What fertilizer is best for tomatoes. Fertilizers for tomatoes Complex mineral fertilizers

Step-by-step feeding of tomatoes is a traditional agricultural technique for caring for a plant, taking into account the phases of development. Indeed, many believe that tomatoes, like any other crop, in the process of their growth, development and maturation, need to be fed. Properly selected doses of mineral water, of course, satisfy all the needs of the culture in obtaining nutrients, but you need to take care not so much about the crop, but about the soil. Let's take a closer look at when and how to feed for a healthy crop and what soil fertility depends on.

Step-by-step top dressing of tomatoes depending on growing conditions

Of course, gardeners most often prefer such substances, after taking which the result is immediately visible. This is, for example, urea. After introducing it into the soil, the tomato bushes become lush, thick, beautiful, but the disease resistance and fruiting of the plant specifically suffer. Therefore, overfeeding tomatoes with nitrogen is not recommended; more attention should be paid to other elements that the tomato lacks.

Top dressing of a tomato must be carried out competently, giving it the whole complex of microelements, and then you will get a plentiful and healthy harvest. You should also know that the composition and amount of top dressing also depends on where the crop grows - in a greenhouse or open ground.

With the traditional approach with the use of mineral fertilizers, the return on top dressing is significantly increased if they are used in phases of development and in a balanced way. A perfect illustration of this is the harvests from narrow beds Mittlider. But you can do without them at all, gradually introducing the principles of organic farming. And since not everyone has switched to eco-farming, step-by-step instruction for feeding tomatoes will be useful to you.

Top dressing of tomatoes in the greenhouse

A greenhouse is a completely different world than open ground. First, here you should take care of the soil in which the tomatoes will be planted. Light and fertile soil should consist of:

• sod land(1 part);
• humus (2 parts);
• sand (0.5 parts).

Add superphosphate and potassium sulfate (1 tbsp per 1 sq.m) in the fall, and urea (1 tbsp per 1 sq.m) in the spring.

Secondly, seedlings prepared for planting in a greenhouse must first (about a day before the process) be carefully fed with Epin-extra, which increases its resistance to pests and diseases, and improves the survival rate.

After the tomato seedlings have taken root in the greenhouse, foliar top dressing should begin. To do this, we recommend using Plantafol (approximately 1 tbsp per 10 liters of water). It is used in different proportions in different phases of development, in total it is necessary to carry out 4 top dressings:

1. 5-7 days after landing in a new place. During this period, phosphorus is important for the culture, so Plantafol is taken with its predominance in the composition (10:54:10).
2. Carry out similarly to the first.
3. For the third top dressing, Plantafol is used, which contains phosphorus, potassium and nitrogen in equal proportions. This combination will stimulate the flowering of the culture.
4. It is carried out when the fruit ovary begins in the tomato. In this case, Plantafol should have an increased content of potassium (5:15:45).

In greenhouse conditions, it is also recommended to carry out top dressing, which contributes to the resistance of the tomato to diseases. The following solution is used: in a bucket of water, dilute 1 tbsp of calcium nitrate and 1 tbsp of Plantafol. Spraying is carried out twice a month.

The use of Italian Plantafol is beneficial for private traders, as it eliminates the rather laborious calculations of fertilizer doses required for a particular development phase. Of course I have, successful experience the use of mineral waters in our country - for those who are interested, be sure to find and study the adaptation of Mittlider agricultural technology to our preparations, author - Ugarova T. Yu. "Family vegetable growing on narrow ridges." There are convenient tables of step-by-step mineral supplements and there is no point in rewriting them.

During the growing season, top dressing of tomatoes must be carried out as follows, observing the sequence of top dressing:

1. The period of color formation. You can pick up store-bought complex fertilizers, in which case you should look at the growth phase for which this or that type of fertilizer is applicable. Or you can use folk methods: bird droppings / mullein (0.5 l) + superphosphate extract. Irrigation dosage - 1 liter in each well. To prepare the extract, take a maximum of 1.5 tablespoons of crushed fertilizer, pour 10 liters of hot water into it, and stand for a day.
2. The second time it is desirable to feed the plants when the second tomato brush blooms. Here, simply complex fertilizer is used, the dosage is observed according to the instructions.
3. It is carried out during the period when the third brush begins to bloom in the tomato. Complex fertilizers are also suitable - 1 tablespoon per 10 liters. Each plant needs to consume about 2 liters of top dressing.

But in the process of feeding there is important rule: in no case should you overfeed tomatoes - an excess of some elements also harms the plant, as well as their lack.

The problem that occurs most often is that a powerful vegetative mass prevents the fruits from growing and developing. If all of a sudden this happened, and the tomato bushes resemble thickets, emergency measures should be taken to help the fetus directly. For this, it is recommended to treat the culture with an extract of superphosphate - 1 liter for each plant. The extract concentrate for this purpose is increased - they take 3 tablespoons of fertilizer, instead of one.

Top dressing of tomatoes in the open field

The most essential nutrients for culture open soils is nitrogen, phosphorus, potassium (NPK), in different periods development, it needs certain microelements to one degree or another.

With the development of tomato fruits, phosphorus is needed, so it is especially important to add it to the soil even when seedlings are still growing. To do this, when planting seeds in a box, they use soil with the addition of superphosphate - 1 tsp per kilogram of land is enough. Nitrogen and potassium can also be added here, but in very small quantities - 1/7 tsp is enough for 1 kg of soil.

Then the tomatoes must be fed in the process of transplanting from the box into open ground. During this difficult period, the tomato needs potassium, which promotes the ovary and ripening of the fetus. Before digging a place for planting a tomato, organic matter is added to the soil - about 5 kg, 1 tablespoon of superphosphate, 2 tablespoons of potassium sulfate - all this per square meter of area.

Tomatoes also perceive well fertilizers such as humus and compost - they are best applied directly to each hole before planting a bush. But manure for open ground can only be added when digging the earth after harvesting, i.e. in the fall, since the introduction of manure into the soil in the spring will contribute to too intensive growth of foliage, to the detriment of the fruits.

In the period from planting to fruit formation, three main root (i.e. soil) top dressings are produced:

1. Carried out at the very beginning of flowering plants. As a top dressing, watering is carried out with the following solution: for 10 liters of water, you will need 0.5 liters of any infusion from organic fertilizer (chicken manure, green grass, mullein). Also during this period, an extract of superphosphate is introduced into the soil.
2. It is carried out when the flowering of a tomato appears on 2 brushes. They are fed with organic matter (exactly the same as in the first case), only 1 tbsp of complex mineral fertilizer is added to the infusion.
3. When the third brush begins to bloom at the tomato, they are fed simply with complex fertilizer - 1 tbsp is diluted in 10 liters of water.

As for foliar top dressing (i.e. spraying tomatoes), they also need to be carried out, according to following principle:

• before the formation of the fetus. During this period, tomatoes are sprinkled with infusion of urea (1 tablespoon of urea + 1 g of potassium permanganate is diluted in a bucket of water);
• After the formation of the fetus. It is recommended to spray with a solution prepared using potassium sulfate, potassium nitrate, potassium magnesia (1 tablespoon of any of them per 10 liters).

For foliar top dressing, the rule applies: the procedure should be carried out in the early morning, or in the evening, when the sun is still or no longer scorching. So top dressing will last longer on the leaves, nourishing them. Root and foliar dressings are best alternated.

Foliar top dressing of tomatoes with iodine

Recently, such a simple preparation as iodine has been used as a top dressing for a tomato. It is he, according to gardeners, that contains components that stimulate the faster formation of ovaries on the bushes and the development of the fetus. In addition, iodine also affects the number of ovaries, which become more with such top dressing.

There are two options for solutions using iodine in the composition:

• Plain iodine solution. Preparation is not difficult: 3 ml of iodine is diluted in a bucket of water. Dosage must be observed! For accuracy, you can use a syringe. Watering with iodine solution is carried out at 0.5 liters for each bush.
• Solution with serum and iodine. Whey is mainly used as a preventive measure against late blight, which affects tomatoes. For 9 parts of water, take 1 part of whey, mix well. After that, iodine is added - at the rate of 20 drops per 10 liters. Tomatoes are sprayed with this solution, not watered. The procedure is carried out 2-3 times a month, preferably in the evening, in calm, clear weather.

2-3 days after iodine treatments, it is important to shed the garden bed with some "live" preparations (EO, compost tea, weed infusion) in order to revive the microflora in the garden. But more on that later, but now let's move on to fertilizers for tomatoes without chemicals.

Folk remedies - the best organic fertilizers for tomatoes

Of course, it is best, if possible, to use as a top dressing for tomatoes. natural remedies , whose action is not inferior in efficiency to store-bought fertilizers, and in terms of "usefulness" they are clearly superior. True, the preparation of nutrient solutions according to folk methods requires more time and effort. But they are definitely worth it.

There are several really effective remedies that will give tomatoes everything they need to get a healthy and bountiful harvest:

• Mullein. The basis of its preparation is fresh cow dung, which is currently not so easy to get. Manure is diluted with water (1 to 3) and left for a week, after which the mullein is ready. For direct watering of plants, mullein is bred: 1 liter of fertilizer per bucket of water. Irrigation dosage - 1 liter per hole. It is not worth overdoing it with mullein - top dressing is carried out no more than 2 times during the entire growth period.
• Infusion based on chicken manure. Also an effective tool, the preparation of fertilizer is similar to the first option. Before watering, the fertilizer is also diluted, only in a different proportion: a bucket of water requires ½ liter of infusion. In order for the tomatoes to better accept the top dressing, they should be poured a little with plain water before the procedure.
• Wood ash. In its composition, it is very similar to a complex fertilizer, which combines calcium, sodium, magnesium, potassium, the lack of which the culture most often experiences. Dry ash is brought into the holes when planting tomatoes, and the beds are also sprinkled with it. But most effective top dressing will be a solution of ash. For root and foliar dressings, it is prepared in different ways:
  • For spraying, the ashes are boiled in water for half an hour. Dosage based on 100 g per liter. After the solution has cooled, it is still diluted with water - 2 liters of plain water should be used per 1 liter of concentrate. In order for the infusion to linger longer on the leaves, add a little laundry soap or other adhesive.
  • For irrigation, the ash is diluted in water at the required concentration. Do not insist, watering is carried out immediately.
• Herbal infusions. This is perhaps the most affordable top dressing for an ordinary summer resident, since there is no need to look for and buy raw materials - it grows right on the site. The richer the composition of weeds for infusion, the better. All of them contain different trace elements: nettle - iron, potassium; dandelion - calcium; alfalfa - phosphorus, etc. The principle of infusion is based on the fermentation of grass in water, while 2 parts of weeds are taken for 1 part of water. The container where the preparations are made must be tightly closed. Thus, 10 days must pass, after which the fertilizer for tomatoes is ready. Immediately before watering, the concentrate must be diluted with water as 1/10. Each bush will be quite enough 1.5 liters. You should not get carried away with herbal infusions - we recommend feeding them tomatoes no more than 2 times a month.
• Yeast. Despite the fact that they do not contain any nutrients, they can serve as a plant growth stimulator - they activate soil biota. In this case, both fresh yeast (diluted in water and immediately watered) and dry yeast (dissolved in water and insisted for several hours before watering) can be used.

Of course, you can prepare a complex solution (as many summer residents do), for example, based on herbal, where to add manure, ash, superphosphate and something else “useful” for tomato. Such top dressing will be replete with all trace elements and nutrients, but there is a risk of overdoing it and “overfeeding” the tomatoes, which means accumulating nitrates in them. So let's look at the problem of plant nutrition from a different angle.

Why You Shouldn't Feed Tomatoes

Properly grown seedlings and a bed rich in organic matter generally almost do not need top dressing. We did not come to this immediately, of course. At first, they also stuffed the earth with chemistry. Gradually, the understanding came that mineral supplements and mistakes in agricultural technology make dependent plants out of plants.

Think for yourself, because they simply have nowhere to go from the garden and have to absorb excess minerals. Here salts accumulate in tissues and fruits. There are more pests on such plants - soft tissues are easier to bite through. Yes, and the fruits are stored worse. Do we need such food?

Now, if we see leaf chlorosis, then we don’t grab onto bags of fertilizers, but immediately pull out the plant and burn it, because. in 99% of cases, it is affected by a viral infection, and it cannot be cured. The rest of the time, we replenish the beds with organic matter, water with weed infusions and occasionally with EMs. That is, we do not feed tomatoes, but soil workers - beneficial microbes and earthworms. We cherish them and cherish them. It is the active microflora that feeds our vegetables, not chemistry.

ancient wisdom says: “A fool grows plants, a smart one grows soil”

Plants feed not at the expense of humus and minerals accumulated in the soil, but with the active participation of biota. These invisible cohabitants of plants, digesting food for themselves with the help of enzymes, supply nutrients in a form digestible for plants. By replenishing the beds with organic matter and preserving the soil structure, we feed our microbe helpers (bacteria, fungi, etc.) and soil animals (earthworms, etc.). That, in fact, is why it is not necessary to feed tomatoes, but to grow fertile soil and increase plant immunity.

Step-by-step feeding of tomatoes still resonates with adherents of traditional agricultural technology. Perhaps such care will be popular for a long time, but one should not forget about the dosages and quantities of fertilizers - overfed plants will not give a bountiful harvest. And remember that, first of all, it is not the plants that need to be fed, but the earth, so that a favorable microflora develops in it, which will provide the tomatoes with all the necessary antibiotics and nutrition.

One of the most important components of the growing process cultivated plants is their nourishment with useful substances. No exception - and tomatoes, which are very demanding and whimsical for fertilization. For tomato are used different kinds nourishing substances that in one way or another affect the development and rapid growth of seedlings, the formation of a strong stem and healthy fruits. Ultimately, the summer resident receives the expected high yield of ripe tomatoes.

Tomatoes very quickly absorb any nutrients, so it is necessary to feed seedlings and mature bushes so as not to oversaturate the soil with one type of fertilizer. To do this, follow the instructions on the package. From personal experience summer residents are advised to carefully study the type of soil and the conditions under which tomatoes grow, both in open ground and in a greenhouse. For example, after planting seedlings in the soil, foliar top dressing of tomatoes is carried out.

It should be remembered that the concentration of the ammonium nitrate solution should not exceed the limit of 0.4%. When the plant goes through the active phase of flowering, the required rate of ammonium nitrate is 0.7%. During the fruiting period, about 90 g / 10 liters are introduced. water. The limiting norm in this case is 0.9%.

Together with foliar top dressing of tomatoes, root top dressing is highly effective. It is this complex that will allow you to achieve maximum productivity. Root top dressing of tomatoes is applied directly to the holes at the time of planting seedlings in the soil, and throughout growing season about three times, approximately every 14-21 days. In this case, the expected yield increase is about 24%.

As a fertilizer, you can use organic (solutions with water of chicken manure, mullein, manure) or mineral (phosphorus, nitrogen, calcium, potassium) in combination or separately, depending on which nutrients the tomatoes lack.

How to determine the lack of mineral fertilizer in tomatoes? It is necessary to consider in detail the types of fertilizers and dressings for tomatoes, as well as the main signs by which it is possible to determine which substances are lacking in plants.

Phosphorus. This is one of the most necessary substances for the growth of tomatoes, especially at the beginning of seedling development in permanent soil. With a lack of phosphorus, the stems of the plant are painted in purple. This process takes place gradually and indicates a poor development of the root system. If only the lower leaves and the bottom of the stems turn purple, you can wait a bit with the introduction of phosphorus recharge. If in purple hue the leaves began to stain in the middle of the stems, immediate feeding of the tomato with phosphorus is necessary.

The best phosphate fertilizer is superphosphate. It is sold in powder or granule form. Its main advantage lies in the fact that in its composition the components are in an easily digestible form.

Nitrogen. This substance is necessary for the plant at the beginning of its development and during the budding period. The first feeding of tomatoes is carried out with nitrogen fertilizers immediately after planting in the ground. It is necessary to monitor the proportions at the first feeding.

If the seedlings are healthy and full of vitality, you do not need to feed immediately. In the event that the plant begins to wither and lose vitality then nitrogen supplementation is necessary. Nitrogen deficiency is characterized by the appearance of yellow areas on the surface of the leaves. The stems gradually become sluggish, and the lower leaves begin to fall off. The most popular and effective nitrogen fertilizers for tomatoes - ammonium sulfate, ammonium nitrate, carbamide, ammonium sulfate. These fertilizers tend to acidify the soil, so after applying them, it is necessary to deoxidize the soil with a liquid lime mixture.

Often the symptoms of poor plant development with a lack of nitrogen are very similar to the symptoms with a decrease in air temperature or abundant watering. Therefore, it is important not to confuse them. Saturation with nitrogen fertilizers can lead to burning of the plant.

Potassium. This fertilizer for tomatoes is responsible for the number of ovaries and inflorescences on the bush. When the process of fruit set has begun, it is already too late to feed the tomato bush. To prevent this from happening, potash fertilizers must be applied in advance. In gardening practice, a lack of potassium in the body of a tomato plant is very rare. Potassium also contributes to the maintenance of the necessary moisture balance. Thanks to this nourishment, the fruits acquire such a property as resistance to change. climatic conditions and a lot of diseases.

Calcium. It is necessary for tomatoes to form the root system, strengthen the stems and form ovaries. It also improves immunity (provides a protective function). Its deficiency is practically not found in tomatoes. In addition to the main top dressing of tomatoes with fertilizers, many summer residents use foliar top dressing in the form of micronutrient fertilizers. The light solution is widely used boric acid(10 liters of water / 10 grams of boric acid). Then the resulting solution is sprayed onto the leaves of the tomato bush.

Complex fertilizers for tomatoes (tomatoes)

Many summer residents are preparing a nutrient complex for high-quality growing tomatoes at home. This can be done if you strictly follow the recommendations and know the necessary proportions. Therefore, it is best for beginner summer residents to buy ready-made complex fertilizer for tomatoes in specialized stores or retail outlets.

The best complex fertilizers for tomatoes:

• Calcium nitrate.
• Diammophos.
• Ammophos.
• Nitrophoska.
• Mortar.
• Potassium monophosphate.
• Nitroammophos.
• Kemira Universal -2.

They include useful substances that are already balanced for a certain type of plant. The process of growing tomatoes requires a summer resident special attention, but at the same time, plants quickly master the resulting complex useful substances and the result will follow almost immediately after the introduction.

Yeast for feeding tomatoes

Yeast is a fertilizer for tomatoes. They are one of the non-standard dressings of tomatoes. It consists in watering the bushes with a solution of yeast and water.

This feeding is distinguished by its simplicity. It does not require a lot of money to make. Economic benefit is the main advantage of this type of tomato feeding.

Preparing this nourishing substance is not difficult:

• You need to take a clean bucket made of plastic or metal (10 liters) and add 20 grams to it. yeast and 30 gr. Sahara.
• The resulting solution must be thoroughly stirred and infused for about 24 hours in a warm place, at a temperature not lower than 20-22 0 C.

After the expiration of the regulatory period, the resulting mixture can be used as a fertilizer. Approximately 200 ml should be added. under 1 bush of tomatoes.

Whatever fertilizer you choose, it is worth remembering that for best effect it is worth using complexes of substances. Those. do not use only organic fertilizers separately, but take them in combination with mineral fertilizers, but correctly calculate the dosage.

Thus, fertilizing the soil when planting tomatoes plays a key role in the growth of future fruits. To date, there are a large number of different fertilizers that can improve the quality of fruits, the main thing is to follow the exact instructions for the dosage and time of applying them to the soil. With the help of top dressing, you can grow an excellent crop of tomatoes on the soil, which is not particularly fertile.

Tomatoes are a fairly demanding vegetable crop. This plant actively takes nitrogen, potassium, phosphorus and other minerals from the soil. During seed germination, phosphorus is necessary to enhance the growth of plant roots, it contributes to more early flowering, ripening of tomatoes, increases productivity, sugar content and dry matter in fruits. Potassium is necessary for normal fruiting, and nitrogen in the ammonia form is necessary for the rapid ripening of fruits. During budding, flowering and fruit formation, plants need nitrogen-potassium nutrition. If there is a lack of nitrogen or potassium, then plant growth is weakened, and this leads to a decrease in fruits and a decrease in yield.

To prepare a good complex fertilizer, you can use stinging nettle and dandelion leaves in any proportion, fill a third of a two-hundred-liter barrel with this mixture, add any manure, pour water and leave covered with a film for ten days. After that, remove the film and the top floating layer. Mix the solution and add the fertilizer "Humate + 7" to it. The finished product is diluted with water in the ratio of a liter of the composition to a bucket of water and each bush is watered with 3.5 liters of the resulting solution.

A popular approach to fertilizing tomatoes is also to use iodine. It accelerates the development of fruits, helps to increase their weight and also disinfects the soil and protects the plant from fungal diseases. The solution is very easy to prepare: for each bucket of water - 4 drops of iodine and water two liters for each plant. Iodine is also used along with milk to nourish, disinfect and increase fruit production. To prepare such a remedy, a liter serum is used, where iodine is added (about 20 drops). Each bush is watered with a liter of such a solution.

Types of fertilizers

Despite all its fertility, after the frequent planting of vegetables and other plants, the soil is depleted and no longer brings such an amount of crop as, for example, in the first few plantings. To help the soil restore its fertility, various types of so-called top dressing are used, i.e. fertilizers. Not all vegetable crops need a high level of soil fertility, such as pepper, but a tomato requires a high level, otherwise it simply will not grow and produce a crop.

Excess nitrogen negatively affects the growth of tomatoes. It delays fruiting, there is a high probability of plant diseases.

Tomatoes are rather capricious plants, therefore their feeding must be correct and effective, with any mistake in the use of fertilizers, they can bring not good, but harm to the plant and deprive you of the crop. Therefore, it is worth paying utmost attention to the preparation of various solutions, because. if you overdo it with some of the fertilizers, the plants can deteriorate or die completely and strictly adhere to the rules for the consumption of fertilizers for each tomato bush.

After all, every gardener knows that a tomato can be demanding and, during its ripening, draws out a huge amount of nutrients from the soil, which are formed into a powerful vegetative mass, which, after ripening, is harvested as a crop.

Thus, in order to get a good crop of tomatoes, you need to create everything the necessary conditions.​
- 0.1-0.2% solution (10-20 g per 10 liters of water) for irrigation in greenhouses and in open ground. Plants are watered 2-3 times a season before flowering or crop formation. During the growing season, saltpeter is used as a surface top dressing at the rate of 10-40 g/m2 before watering, or as a foliar top dressing in open ground with a 1% solution (100 g per 10 l of water) when using a pneumatic sprayer. If necessary, the treatment is repeated after 7-10 days.

When growing tomatoes, ammonium nitrate (it contains 34% nitrogen), ammonium sulfate, or ammonium sulfate (20.5-21.5) and urea, or urea (46% nitrogen) are most often used. All ammonium fertilizers cause acidification of the soil, which adversely affects the growth of tomatoes and other vegetable crops. To neutralize 1 kg of ammonium sulfate applied, the same amount of lime from the soil is consumed.​

The second feeding can be carried out both root and foliar.

Important: you should not overfeed the tomatoes before the fruit is set with ammonium nitrate, mullein or bird droppings, as an excess of nitrogen in the soil will cause the plant to “get fat” - it will form a strong stem with abundant foliage, however, it will not bloom and bear fruit. It is important not to over-fertilize the plants, as an overdose of any drug can adversely affect internal state fruits. For this, humus or mineral fertilizers. But if you skipped this stage of soil preparation, you will have to feed the tomatoes during their growth and development if you want to get a rich harvest.

• Soil enriched with organic materials and biofertilizers is the key to a rich harvest of tomatoes.. Intended​
• - this is a simple powdered or granular superphosphate (14-19% phosphorus) and double granular superphosphate (45-50% phosphorus). Foliar (spraying) - dilute 2 tablespoons of superphosphate in 10 liters of water.
• To eliminate such a deficiency, root dressing can be carried out by dissolving Phosphorus fertilizers applied to the soil contribute to the resistance of plants to various adverse conditions, the development of a strong root system and good fruit set.

During fruiting, greenhouse tomatoes, to accelerate the ripening of fruits, can be fed with the following composition: 1st. l nitrophoska, 1h. l dry sodium humate powder, diluted in 10 liters of water. For every 1m2, 5 liters of working solution are consumed. In the event that you have applied too much nitrogenous fertilizer with your own hands and your tomato has “burned”, then here is an instruction on how to fix it: : first you should water the plants, and then introduce nutrients.​

In this case, the tomato must be fertilized at the initial stage of development, when the plant really needs nitrogen. But it is worth remembering that in working with such demanding plant Like a tomato, it is better to underfeed than to overfeed. Better yet, just give the plant as many nutrients as they require at various stages of development after planting.

Recently, summer residents are trying to abandon chemical, artificial fertilizers, preferring natural top dressing. How to fertilize tomatoes, everyone chooses for himself, as there are many options.

1. for use under all garden and horticultural crops. It has a neutral reaction, so it does not acidify the soil. One of the main advantages of this fertilizer is its environmental friendliness: it is completely absorbed by plants without polluting environment. With the systematic use of "Universal", the content of humus in the soil increases. Potash fertilizers For the third fertilization - carry out root dressing. In a ten-liter bucket, dilute 50 g of urea or 2 liters. Potassium nitrate. The lack of this trace element can manifest itself: 2 g of boric acid in 10 liters of water

• Then you need to feed the tomato during its flowering. At this time, the plant is in great need of potassium and phosphorus. It is very easy to notice when a plant needs one of these substances - its growth slows down, the leaves curl, and the color of the plant changes. Yeast is one of the best plant growth stimulants. It is used dry when digging, it is used in the form of potassium salt (30-40% potassium), potassium chloride, or potassium chloride (52-60) and potassium sulfate, or potassium sulfate (45-50% potassium). ​Fourth foliar top dressing- for 10 liters of water - dilute 15 g of urea and spray the cucumber beds with the resulting solution.

The first time it occurs after two weeks from the time of planting seedlings in the ground to stimulate the growth of the roots and the plant itself. The second top dressing occurs after two weeks after the first, and the third, foliar top dressing of the tomato, either during flowering or already the formation of fruits. Finally, the last feeding is usually carried out at the time when the plants are in the fruiting stage.
2. What to feed tomatoes? The most common feeding methods are: bird droppings, ash, yeast and others. Let's take a closer look at each of them.​
3. - 100 g/m2 on cultivated and 150 g/m2 on non-cultivated soils locally in holes and furrows; when planting seedlings - 20 g per hole (the fertilizer is thoroughly mixed with the ground), when feeding - 30 g / m2, followed by loosening and watering (if necessary).

Nutrients needed for greenhouse tomatoes

In the first feeding, slurry is used (8 l of water / 1 l of slurry).

• The appearance of spots along the leaf veins, which later die off;
• Tip: In order to stimulate fruit set, you can use foliar top dressing with an aqueous solution of boric acid. 1 g of boric acid is dissolved in one liter of hot water, after which the solution is cooled. The inflorescences are sprayed with a warm solution.
• The leaf blade begins to curl along the main vein;

1. At the moment, there is a huge number of different fertilizers for any stage of plant growth. In the case of tomatoes, both mineral fertilizers and organic fertilizers can be used, they can be both in dry form and in the form of solutions.

Yeast. They are the best plant growth stimulator.​ For refueling the soil In large doses, a high concentration of chlorine is created in the soil, which can damage the tomato root system, especially in greenhouse conditions. Potassium salt poses the same danger. Chlorine noticeably worsens the taste of fruits.

For the second, ash is suitable as a fertilizer (1 tbsp. ash / 10 l of water). Stir and apply under the roots of plants.

The stems of the plants are quite thin and woody.

Potassium

This microelement plays an important role throughout the entire vegetative period of tomatoes, but it is especially necessary during the formation of ovaries and fruit development.

Red and purple spots appear on the underside of the leaf;

1. – up to +220С
2. In order for a tomato planted in a greenhouse or greenhouse to please the gardener good harvest tasty fruits, it is necessary not only to create in a greenhouse or greenhouse the conditions of humidity, light and temperature necessary for plants. For good growth and fruiting of tomatoes, a wide variety of nutrients are needed, which must be complete and balanced.

It is worth remembering that top dressing of tomatoes should take place only in the bite zones, and not on the plant itself, otherwise it may begin to rot and will not bring the expected harvest.

Recipe for the preparation of yeast fertilizer: 20 grams of yeast is diluted in 10 liters of water, left for 24 hours, plants are fertilized with the resulting solution. "Rostmoment" is a ready-made fertilizer, which is produced on the basis of yeast. It is also suitable for planting tomatoes. This tool is the best biostimulator of growth and further development of plants. Using this fertilizer, you can be sure of its quality. "Rostmoment" is suitable for fertilizing tomatoes that grow in pots.

• When growing seedlings, 10 g of fertilizer per 1 kg of soil is applied, mixing thoroughly. The composition of the fertilizer includes,% -. humic compounds - 3.2, nitrogen - 7, phosphorus - 7, potassium - 8, magnesium - 1.5, sulfur - 3.8, iron - 0.1; is in it and essential trace elements- zinc, copper, manganese, molybdenum, boron.​
• In recent years, complex complex fertilizers containing several nutrients have become widespread. Among them are ammophos, nitroammophos, diammophos (contain nitrogen and phosphorus), potassium nitrate (contains nitrogen and potassium), nitrophoska, nitroammophoska, mortar, etc. Magnesium and sulfur fertilizers, microfertilizers are also used. Of the new fertilizers, it should be noted Kemira (several types), solute, etc.
• For the third fertilizer, the Gummi preparation is best suited (10 l of water - 2 l of the preparation).

Phosphorus

To eliminate zinc deficiency, zinc sulfate can be applied directly to the soil, at the rate of 2-3 g per 10m2, or sprayed with an aqueous solution of zinc sulfate.

slowing down the process of fruit ripening.

• Let us dwell in more detail on the question of what time and how to feed the tomatoes in the greenhouse.
• If tomatoes do not get enough of any substances they need, then the price of such a deficit is quite high: their growth slows down or stops altogether, it is difficult to set and ripen fruits.

First of all, plant nutrition occurs with the help of organic fertilizers, which are organic compounds containing plant nutrients needed for good development and harvest. Manure is a natural organic fertilizer for tomatoes.

trace elements

Ash is an excellent source of potassium and phosphorus, magnesium, sulfur, zinc and other trace elements. Ash is added before planting seedlings in each hole. To do this, take 3 tablespoons of ash and mix it with the soil. For enrichment soil 3 cups of ash per 1 square meter are required.

"Solution" is a complex water-soluble fertilizer containing nitrogen, phosphorus, potassium and magnesium in the optimal ratio for plants, as well as trace elements. This fertilizer is indispensable for growing a wide range of crops. Kemira Universal 2 is a complete mineral fertilizer used during spring digging of the soil. The recommended rate for tomatoes is 150-160 g / m2, however, it can be divided into the main dose, which is 90-100 g / m2, and two top dressings during the growth period - 30 g / m2. 2 - 3 weeks before the planned harvest.​

Tip: to carry out a comprehensive feeding of tomatoes with microelements, you can use a decoction of wood ash. To do this, 3 cups of ash are boiled for 20 minutes in 0.5 liters of water. After the broth has cooled, it is filtered, and then topped up to 10 liters of water and sprayed.

• Magnesium deficiency manifests itself on tomatoes during the mass laying of ovaries and fruit ripening, and manifests itself as follows:
• Tip: The first top dressing of a tomato in a greenhouse can be done while planting seedlings in a permanent place. To do this, 10-15 g of superphosphate are added to each prepared well.
• Nitrogenous fertilizers are needed at two main stages of tomato development:
• To stop the development of the green mass of tomatoes, root dressing is carried out with an aqueous solution of superphosphate, diluting

In the event that an excessive amount of organic or mineral fertilizers was applied to feed the tomatoes in the greenhouse, the plants are oppressed and may die, as severe dehydration occurs.

Bor

Of course, before using this tool, you should pass through the compost and in no case use it raw. This folk method of feeding is very effective, because. the manure of hay-eating cattle has a huge amount of nutrients.​

A key role in the growth of fruits is played by fertilizing the soil when planting tomatoes.

Particularly effective

• Apply fertilizer
• Tip: When choosing fertilizers for growing cucumbers in a greenhouse, choose those that do not contain nitrate nitrogen.
• The first condition for obtaining a high yield of tomatoes and cucumbers is fertile soil. Naturally, every year the earth, endowing us with a generous harvest, loses many beneficial trace elements, therefore, to replenish stocks, fertilizers for cucumbers and tomatoes should be regularly applied. Usually fertilize the soil before planting, during its process and after planting vegetables.
• Leaf discoloration, starting with old leaves of the lower tier;

After transplanting into a greenhouse or greenhouse. 3 st. spoons of the drug in 10 liters of water

At each stage of its development, a tomato needs various top dressings, which we will discuss in more detail.

Magnesium

Another option for feeding a tomato is bird droppings, which is a very strong fertilizer containing a large amount of nitrogen.

Chicken manure is a fairly valuable fertilizer. Its chemical composition is ahead of manure, and the nutrients are contained in a fairly light form. Feeding tomatoes with chicken manure has a prolonged effect, even after two or three years after fertilization, the soil remains saturated and has a positive effect on plants. Feeding from bird droppings is prepared quite easily. The concentration of the solution is prepared depending on the stage at which the tomatoes grow. You can prepare the following composition: 100 g of fresh bird droppings are added to 10 liters of water, infused for 24 hours and the plants are watered. Top dressing with manure with bedding is applied during tillage, in the ratio of 6 kg of fertilizer per 1 sq. m. Chicken manure is not a universal fertilizer, therefore, in addition to it, it is necessary to add other top dressing to the soil, such as ammonium nitrate, superphosphate.

"Solution" for root and foliar feeding of plants (apply 15-25 g / m2 for vegetable crops), since the nutrients in its composition are absorbed by plants very quickly, which allows you to quickly regulate plant nutrition.

• It is necessary before spring digging, evenly scattering it over the used area. Best result gives the introduction of full fertilizer in the holes when planting seedlings or in rows with seedless technology. To prevent contact of seeds with fertilizer, the soil in the beds and holes is mixed.
• Fertilizers for tomatoes can be purchased ready-made, or made independently.
• ​Cucumbers are a crop that is very demanding on soil fertility; for active growth, it is necessary to provide a nutritious habitat that will help ensure excellent harvest. The best soil for the development of cucumbers is light loamy soil with a neutral reaction, enriched with humus.​

Gradual spread of yellowing (see Why tomatoes turn yellow - a professional look) and discoloration from the bottom of the tomato bush up; In addition to macronutrients, tomatoes need a lot of micronutrients. According to experienced gardeners for good fruiting and obtaining a quality crop of tomatoes, you need aboutAfter the formation of ovaries on the first two brushes in most tomato bushes.

Manganese

. The resulting solution is used at the rate of 1 liter per plant.

• But chicken manure is not very actively used in tomato fertilizer, because. has a very strong odor and contains helminth eggs and weed seeds that can harm the plant as well as benefit it. But science has been able to solve this problem too. To date, gardeners are offered to use chicken manure to fertilize open ground not in raw form, but in dry form. It is dried at very high temperatures, which provides cleansing of unnecessary, but the preservation of nutrients and odor reduction.​
• For a good result, it is not necessary to use expensive fertilizers, the main thing is not to exceed the dosage and apply them to the soil in time.
• Magnesium sulfate is an effective magnesium sulfur fertilizer containing 16% magnesium and 13% sulfur. Magnesium deficiency occurs most often on soddy-podzolic, acidic sandy soils. As a general rule, the lighter and more acidic the soil, the more severe the magnesium deficiency can be.​
• Feed the plants
• The main rule when growing tomatoes is to observe the optimal dosages when using fertilizer for tomatoes, because an excess of organic additives (manure, chicken manure), mineral nitrogen fertilizers can lead to negative consequences. Phosphorus-potassium compounds should be preferred; ash will also be useful for potassium sulfate.

For cucumbers, it is best to use fractional (partial) fertilization, as plants require a large amount of nutrients, however, an excess of minerals can also have a negative effect. Deciding on fertilizers is not an easy task, because, depending on the stages of development, various trace elements and minerals should be introduced.​ Yellowing of the leaves while maintaining the green color of the veins. 20 trace elements

Zinc

As mentioned above, if the seedlings have greatly outgrown, and besides, they were grown in low light conditions, and after transplantation remain weak and elongated, then through

Experts, answering the question of when and how to feed tomatoes in a greenhouse, recommend adhering to a certain scheme for applying various fertilizers during the growing season of tomatoes.

Quite often, seedlings of home-grown tomatoes are very stretched out, and by the time they are transplanted into the greenhouse, they look, to put it mildly, “not very”. (See How to fertilize tomatoes)​

• Nitrogen can also be obtained from leguminous plants. You just need to make a few plantings of leguminous plants in the ground where you plan to plant tomatoes, and you will not need any fertilizers and top dressing, because legumes are excellent soil enrichers with nitrogen and also, thanks to their developed root system, become soil leaveners.
• Nitrophoska and other complex fertilizers are applied during seedlings of tomatoes, 0.5 teaspoon per 1 liter of water.
• When applied to the soil

You can do it superficially by spreading fertilizer lightly mixed with the soil around them or along the rows. After that, the plants should be watered abundantly. Feeding rate 30-40 g / m2.​

Tomatoes, unlike cucumbers, prefer slightly acidic soils than neutral compositions.

• Another folk approach to fertilizer, which has been effectively used by many gardeners for quite a long time, is the use of green manure, i.e. herbal solutions. They are very easy to prepare and all they need is herbs. The most commonly used nettle. It is cut, placed in a barrel, plastic or wooden, and filled with water.
• Planting tomatoes begins with the use of superphosphate, 1 tablespoon per well.
• This fertilizer increases crop yields, improves the taste of vegetables by increasing the content of starch and vitamins in fruits.

When growing tomatoes, you should remember

If you are an experienced gardener, and have some idea of ​​​​fertilizers, then you can safely add potassium, phosphorus and nitrogen to the soil, as independent element, focusing on the need for cucumbers in a particular period of growth.​

10-15 g of the drug per 10 liters of water

The most significant are:

The use of mineral compounds:

1. It can be fed with nitrogen-containing fertilizers. Such root dressing will give a powerful impetus to enhanced growth and development of the root system and the bush itself.
2. 14-20 days
3. 10 liters of water 1 liter of mullein
4. After that, they are left to ferment, stirring the contents daily to release oxygen from the solution. Shortly after the start of fermentation, a not very pleasant smell may appear, but this can be easily eliminated by adding a few drops of valerian to the barrel. After two weeks of fermentation, you can open the barrel and if the solution has cleared up, then it has fermented and is ready for use. But it is worth remembering that such a mash is unsuitable for direct watering of the plant, it must first be diluted and only then used this remedy like fertilizer. Usually, to dilute nettle mash, a ratio of 1:10 is used and the plant is watered under the root.
5. 5 days after planting, you can water the tomatoes with a weak solution of potassium permanganate.
6. Use it separately or together with other mineral fertilizers - at a dose of 12-15 g / m2. It is especially effective when feeding

The best complex mineral fertilizers for tomatoes

10 liters of water

50 g ash Mineral fertilizers are an excellent addition to organic ones, and are used at all stages of tomato growth. The most popular mineral fertilizers are phosphorus, potash and nitrogen. Phosphate fertilizers are mainly phosphate and superphosphate, which contains a whole range of substances useful for the plant, such as phosphorus, calcium, sulfur and, of course, nitrogen, which act on the plant from different angles and bring different benefits.​

In spring, it is necessary to fill the soil with mineral fertilizers: 80 g per 1 square m of superphosphate and 20 g per 1 square m of potassium chloride; 3-5 g / m2 1 time in 10-15 days. You can carry out foliar top dressing with a solution of magnesium sulfate (15 g / 10 l of water).

Apply When planting seedlings in the soil, add manure or bird droppings to the holes (plants will grow, not fruit ovaries).

The leaves are rounded, wrapped down - calcium deficiency. Manganese deficiency manifests itself:

Kemira Universal2

Tomato, a very rapidly developing plant, which needs potassium for development, which contributes to the formation of stems, the setting and development of fruits, the manifestation of varietal taste, as well as a beautiful appearance. ​.​ Potash mineral fertilizers are usually used during fruit ripening, which helps them develop taste and avoid the appearance of green veins inside. Potassium monophosphate - a water-soluble concentrated phosphorus-potassium fertilizer, contains 50% phosphorus and 33% potassium. It is in the form of dressings: 1 tbsp. a spoon (20 g) is dissolved in 10 liters of water and used to fertilize tomatoes in protected ground 1 time in open ground - 1 time in two weeks.

In addition, ash, as a mineral fertilizer for plants, is a highly effective substance. However, it is worth paying attention to what such ash was made of, because. it may contain different amounts of potassium depending on the source material. Thus, pine and birch contain the largest amount of potassium - almost 40 percent. http://youtu.be/7vTOvlEgtQM​

Magnesium sulfate

for plant nutrition, root and non-root, in the generative phases of development. When root feeding, plant roots effectively absorb phosphorus and potassium, which contributes to optimal metabolism. Root top dressing is carried out either with dry fertilizer, distributing it over the surface no closer than 8 cm from the plant stem, followed by loosening, or with a solution at the rate of 7.5-15 g / m2 per 10 liters of water. Foliar top dressing is best done in the morning or evening hours, using sprayers or sprayers.​ 1 st. a spoonful of fertilizer is dissolved in 20 liters of water and watered with this solution once a week. It is not recommended to change fertilizers for tomatoes. Best Option, choose one of the complex mineral compositions(for example, ammophos, diammophos, nitroammofoska, etc.) and use it together with organics, adhering to strictly defined dosages. Before choosing a fertilizer for tomatoes, take into account the characteristics of the soil. 1 top dressing - 14 days after planting in the ground. yellowing of the leaf blade, starting from the tip; This trace element is responsible for the quality of the tomato, namely for the saturation of the fruit with vitamins and sugars, as well as for its size and keeping quality.

With the nitrogen type of fertilizers, you should be very careful, because. with an immoderate dosage of such a remedy, the soil will become too toxic, due to which the tomato will grow too quickly, but the fruits will be disfigured: cracks and spots appear, the shape and taste change. But with moderate use of such a mineral fertilizer, it will help plants grow and develop normally. The nitrogen type of fertilizer includes urea and various types of nitrate, such as ammonium, potassium or calcium nitrate. Urea for tomato fertilizer can be used in small quantities, and the consumption rate of such a solution will be half a liter per plant.
