How to dilute urea for spraying shrubs. Autumn garden treatment with urea and iron sulphate

The use of urea in the garden as a fertilizer is in demand, if necessary, to improve the soil characteristics of any type of soil, as well as as a top dressing garden trees, berry plantations or garden plants. To get the maximum effect, the instructions must be followed, both in terms of the timing and the dose of urea application.

Carbamide: appearance and chemical composition

Carbamide or urea is chemical compound, the end product of protein metabolism and the most concentrated nitrogen fertilizer known to date. The release form is granular, which provides the fertilizer with excellent physical characteristics, and also prevents caking and allows urea to keep good performance dispersion.

This type of fertilizer is used to feed any agricultural and horticultural crops in the form of a solution, it is also in demand as a root and foliar top dressing. Carbamide is actively used as a component in the production of complex fertilizers, and is also included in many slow-acting nitrogen-containing fertilizers.

In its pure form, urea is a colorless crystalline substance, Odorless and having the following characteristics:

• solubility in aquatic environment depends on temperature regime liquids and can vary between 50-95 g;
• the substance is soluble in media such as methanol, ethanol, isopropanol and others;
• characterized by the ability to form compounds with the inclusion of inorganic and organic substances.

Colorless fertilizer granules, represented by urea, have sizes in the range of 1-4 mm, and the mass fraction of nitrogen is 46.2%.

Instructions for using urea in the garden as a fertilizer

Urea is highly soluble in water, when applied to soils, it has the effect of slightly acidifying the soil, therefore, if necessary, liming is performed.

The introduction of urea into the soil must be carried out in advance, at an early spring period or for autumn plowing. It is allowed to use amide substances in the form of aqueous solutions during irrigation, or in the process of direct mixing with the soil during loosening.

Foliar feeding of garden plants is indicated for any vegetable crops with severe nitrogen starvation, and also if there is a massive shedding of ovaries. In this case spraying green mass with a properly prepared urea solution is especially effective and gives the fastest positive results. To prepare such a solution for foliar nutrition of plants, it is necessary to dissolve 5-10 g in a liter of water. room temperature. This quantity is enough for processing 20 sq.m of ridges. It is necessary to produce such an event only in the morning hours or evening time, after sunset.

Features and options for using urea in the garden

When using urea, it should be remembered that the application as a granular fertilizer involves a shallow incorporation into the soil, which will prevent the urea from being washed out of the soil during rains or irrigation.

It is important to note that this method of protection is strictly prohibited for use on vegetable crops ah, and neglect of the rule causes the death of the aerial part of garden plants.

For the treatment of the crown of fruit plantations, it is recommended to use a solution based on a bucket warm water, in which you need to dilute 0.5 kg of fertilizer. With this amount of funds, about ten can be processed. square meters garden plantings and berry bushes. Spraying of trees and bushes is carried out in autumn, immediately after leaf fall. As a rule, it is enough to perform only one treatment to get rid of insects and pathogenic microflora.

How and when to feed trees and shrubs with urea

If plants need not only effective protection, but also high-quality top dressing, then fertilizers are applied to the near-stem circle in compliance with the following standards:

• young apple and pear trees - 0.15 kg;
• fruit-bearing apple trees and pears - 0.25 kg;
• young cherries and plums, as well as other stone fruits - 75 g;
• fruit-bearing cherries and plums, as well as other stone fruits - 0.12-0.14 kg;
• berry crops– 75

Surface top dressing trunk circles is carried out by spraying the solution, after which the soil is cultivated with a rake. It is most effective to carry out such an event in the spring, as well as at the stage of active fruiting of garden plantations and berry bushes.

Advantages and disadvantages of urea as a top dressing

Urea or urea, used as a top dressing, has a significant number of positive properties, among which the most important are the following:

• a urea-based solution is quickly and effectively absorbed by any crops that are hypersensitive to high soil pH;
• properly performed foliar top dressing is not capable of causing burns on leaf plates in plants;
• timely carried out, in compliance with the norms of application, top dressing with urea can significantly increase the yield of not only fruit and berry, but also garden and vegetable plants.

Urea is not without some disadvantages that must be taken into account in the process of feeding fruit, berry, vegetable and green crops:

• an increased concentration of carbamide in the soil very often becomes the main reason for the decrease in germination rates seed material;
• when storing fertilizer, certain rules must be observed that allow you to maintain the activity of the active substance;
• urea should not be mixed with other compounds used to feed horticultural crops.

The principle of operation of the active component is very simple. When it enters the soil, a reaction occurs with spherative components and earthen bacteria.

During the first couple of days, there is a rather stormy chemical reaction, which converts the introduced urea into ammonium carbonate. Contact with air causes the transformation into ammonia gaseous state. It is for this reason that it is necessary to thoroughly incorporate the introduced substance into the upper soil layers. It should be remembered that when using such compounds on soils that have a strong alkaline or simply neutral reaction, significant losses and a decrease in overall efficiency are very often noted.

Fertilizers for the garden: varieties (video)

Urea is currently considered one of the best forms of nitrogen fertilizer, suitable for both foliar and root dressing of any garden plants and fruit crops. Properly diluted and applied in accordance with the instructions, the compositions do not burn the foliage of garden crops and are able to be absorbed in the form of a whole, not decomposed molecule, which has a positive effect on the qualitative and quantitative characteristics of the crop. When used on light-composition soddy-podzolic soils with sufficient moisture and good irrigation, the use of urea is more effective than the introduction of ammonium nitrate.

Due to the fact that bacteria multiply rapidly under the bark of untreated trees, the vegetative process slows down. Plants slowly "wake up" after winter. Therefore, the processing of fruit trees in the fall is very important. To do this, you need to prepare the plants. Processing of trees that are older than six years begins with the removal of old bark and lichen wire brush. This is necessary so that pathogens of various diseases cannot hide. Immediately after removal, the trees need to be processed. The last spraying in the fall occurs when all the foliage has fallen. You can perform this procedure after the first frost. To begin with, all foliage, fallen branches and weeds are removed. The protection of fruit trees is provided by solutions of copper or iron sulphate, urea, etc. Each drug is aimed at certain type threats. Therefore, the processing of fruit trees in the fall cannot consist in spraying with only one agent. The drug is selected according to required results. It is recommended to carry out the procedure in question at the end of October.

inkstone

This drug is intended for spraying and feeding fruit trees - apple trees, cherries. After the procedure, the plants are saturated with iron and useful trace elements. Processing fruit trees in autumn helps to improve oxidative processes. The drug fights pests, destroys lichen, scab, moss, black cancer, cytosporosis. iron plays big role in the life of fruit trees. Its lack reduces the amount of yield and leads to incomplete development of the fruit. It is very easy to prepare a solution of ferrous sulfate. It is necessary to dilute one kilogram of dry powder in a fifteen-liter bucket of water.

blue vitriol

This remedy, which includes a fungicide, prevents the appearance of putrefactive diseases, scab, powdery mildew, spotting. it is recommended to spray trees twice - in spring and autumn. Processing fruit trees in autumn blue vitriol especially recommended for pears, apples and plums. You can, of course, spray other plants in the garden. Copper sulphate provides plums defensive reaction from moniliosis, clasterosporosis, coccomycosis, curly. The remedy protects pears and apple trees from scab, moniliosis and phyllosticosis. For fruit trees (up to six years old), up to two liters of copper sulfate per seedling is enough. Consumption for older plants - up to ten liters. Fruit trees are recommended to be sprayed in the morning or evening. The weather should be calm, and the temperature should be from +5 to +30 degrees. From contact with the drug, it is necessary to protect people and animals, and also to prevent it from entering water sources.

Treatment with urea (urea)

Apparatus for processing

The processing of fruit trees in autumn is simplified thanks to existing mechanical or manual principle actions. These devices protect the gardener from contact with the preparations, spray them evenly. Regardless of the principle of operation, all devices are equipped with a spray pump. The differences between mechanical devices and manual models are the convenience of their use. And, of course, there is a difference in their cost. Mechanical devices are more convenient, but more expensive. And for spraying trees with handheld device periodic pumping is required.

Additional processing

The processing of fruit trees in the fall from pests and diseases should not be limited to spraying with copper, iron sulfate or urea. Plants also need to be watered and whitewashed abundantly. The layer of lime on the bark should be at least three millimeters.

If the tree has cracks and wounds, then a little cow dung and finely chopped straw should be added to the lime. The resulting solution will protect the plant from cracking.

Another way to protect is garden pitch. You can buy it at the store or make your own. To do this, you need to take one hundred grams of rosin and two hundred grams beeswax. It is necessary to melt these substances (each separately), then mix them and add one hundred grams of unsalted fat. Before filling cracks, the var must be heated.

Autumn preparation in the southern regions involves pruning trees. In northern cities, this will doom the plant to freezing.

For fertilizing garden and ornamental crops nitrogen fertilizers are needed. With their help, plants intensively start to grow, acquire large leaves saturated color. This article is all about the application of urea, which improves the growth of green spaces in the city and rural greenhouses. Get to know practically proper feeding plants with urea, you can by watching the video.

Urea: from what and for what?

The first of the synthesized protein compounds is urea. Such scientific name wears urea - a fertilizer for feeding garden and ornamental crops, which is used to accelerate growth. Carbamide belongs to the group of nitrogen fertilizers, it is used in agriculture from the 18th century.

The product is produced by the method of synthesis from inorganic substances, is a granular mass consisting of rounded milky granules, sometimes translucent. At present, industrial production of carbamide has been established in the form of tablets.

Urea can be purchased in the form of granules

By chemical composition almost half of urea consists of pure nitrogen, which dissolves without residue in any liquids, including water.

When applied to the soil, granular urea gradually dissolves in the water that the plants receive when watering. Slowly entering the plants, dissolved urea nourishes the roots for a long time, gradually, throughout the entire period of cultivation. In the soil, nitrogen changes its chemical composition, from the amide form to the ammonia form, and then to the nitrate form. A slow change in the chemical composition guarantees prolonged plant nutrition with the substances necessary for growth.

Nitrogen starvation is manifested in plants in growth retardation, yellowing of leaves, inhibition of plant development and complete death. The introduction of urea is shown when fruit trees and berry bushes form unnaturally thin and short branches with small discolored leaves. Nitrogen deficiency is expressed at the beginning of leaf fall in summer period when most of the leaves on plants turn yellow in more early term than it should be in nature. In spring, plants with a lack of nitrogen form weak, underdeveloped buds.

It is allowed to feed with urea fruit trees and shrubs, effective fertilizer for strawberries, strawberries, all vegetable crops, including cucumbers, tomatoes, peppers, eggplants, carrots, etc.

Urea - how to apply fertilizer correctly

When fertilizing with nitrogen fertilizers, in particular carbamide, several types of plant nutrition should be distinguished:

Pre-sowing treatment– urea granules are applied during spring plowing into the furrows. The depth of embedding urea in the ground is at least 4 cm.

Fertilization

Top dressing with urea during planting events – the best option is the use of the composition in combination with potash fertilizers. At the same time, it is not allowed that the granules are mixed with seeds, it is necessary to provide a layer of soil between granular fertilizer and seed.

Fertilization during growth- most effective method is foliar top dressing landings. To do this, carbamide is dissolved in water, spraying on the green mass is carried out in the early morning hours or at sunset, in calm weather.

Important! Foliar top dressing with urea is not recommended on days when precipitation is observed.

An aqueous solution of carbamide does not burn the leaves, it is convenient to spray the plants with the help of special pumps. The usual rate for diluting the solution is from 9 to 15 g of carbamide per 10 liters of water, while it matters which plants are planned to be treated - herbaceous plants sprayed with a more gentle composition, trees and shrubs - concentrated. Adult apple and pear trees need top dressing in the ratio of 200 g of dry urea per bucket of water. For cherries, plums and apricots, the consumption of urea will be 120 g / bucket.

Important! One st. a spoon holds 10 g of urea; matchboxes - 13 g; faceted glass - 130 g of urea.

Treatment with urea from pests

Spraying with urea effectively helps in the fight against plant pests. Spraying is carried out in the spring, when a constant average daily temperature of +5 C is established. It is important to carry out the procedure before the awakening of the kidneys, then all pests wintering in the scales and under the bark will be guaranteed to be destroyed.

A solution of urea for pest control is prepared at a concentration of 50 to 70 g per 1 liter of water. Spraying with urea helps to destroy aphids, weevils, copperheads and a host of other pests.

Nitrogen treatment of the garden can be carried out both in autumn and in spring.

In autumn, at the time of the first stage of leaf fall, it is useful to spray trees with a solution of urea on which traces are seen. infectious diseases: scab, all types of spotting, rust and others. Trees are treated with a solution along the crown and leaf litter. This processing is very effective remedy from infectious diseases of garden trees, the garden next year will not be affected by infections. Simultaneously with the treatment, the urea solution fertilizes the plants.

Pros and cons of feeding plants with urea

The positive properties of urea are:

• When fertilized with carbamide, plants easily absorb nitrogen, which has a positive effect on their growth and the growth of green mass.
• Treatment with a solution of plant fertilizer on the leaves does not cause burns leaf blade, this foliar top dressing is an effective and gentle remedy, which, along with fertilizing plants, is able to effectively deal with garden and garden pests, as well as pathogenic infections.
• The urea solution is quickly assimilated by plants sensitive to elevated soil PH values.
• Excellent results were noted when fertilizing plants with urea in irrigated areas, as well as when applying under crops grown when filling beds with water.

It is very important to observe the dosage when fertilizing

• Guaranteed increase in yield in the garden or in the garden when feeding plants with urea.
• Ease and simplicity in foliar treatment of plants and the introduction of urea into the soil.
• Availability of fertilizer at a price and the possibility of acquisition.

The disadvantages of feeding with urea are the following aspects:

• A strong concentration of fertilizer when applied to the soil when sowing seeds can affect the reduction in seed germination and delay their germination.
• Urea requires careful storage.
• The use of urea in a mixture with phosphate fertilizers is possible only when mixing absolutely dry substances, hyperacidity from the effects of mixed top dressing must be neutralized by introducing chalk into the soil.

Advice! It is necessary to store granular urea in a dry place, otherwise the fertilizer absorbs moisture strongly and turns into lumps.

The size of the harvest depends on each gardener. Timely and competent application of fertilizing is able to ensure soil fertility and the full return of horticultural and garden crops to the nutrients received on time.

To make your garden look well-groomed, bushes beautiful, fruit trees were healthy and gave in the summer good harvest, it must be properly prepared for the season. One of these important activities, in addition to whitewashing and pruning trees, is their spraying, and carbamide (urea) is considered the most effective means for this. Treating trees with urea solves several problems at once.

Urea refers to nitrogen fertilizers the highest concentration is almost 46%. Some beginner gardeners confuse it with saltpeter, which can be harmful to tree foliage. Carbamide is produced in the form of granular crystals of white and yellowish tints, which have absolutely no bad smell, easily dissolves in water (in hot water up to +80°C the process is faster) and is perfectly distributed on the treated areas. Due to its hygroscopicity, it must be stored in airtight containers. Gardeners value urea not only for its high nitrogen content, but also for high speed digestibility by plants. This is especially effective in dealing with harmful insects when every minute counts.

When working with urea, keep the following in mind:

1. Carbamide belongs to organic compounds, but is considered a mineral nitrogen-containing fertilizer.
2. The action of urea begins immediately and has a long period.
3. Urea for the garden as a fertilizer is applied directly to the soil, since it has the properties of weathering.
4. It is used in any soil, including in protected conditions (in greenhouses and greenhouses).
5. Shows good efficiency on waterlogged soils.
6. In soils with high biological activity, carbamide loses less nitrogen, which cannot be said about alkaline and neutral soils.
7. Getting into the soil, urea is converted into ammonium carbonate (ammonium carbonate).
8. It is the most effective and safe nitrogenous fertilizer for garden plants in the summer - does not burn the foliage even with the wrong dosage.
9. Another one of the very useful properties urea is that it slows down growing season- flowering of trees begins later, and this helps to avoid the death of ovaries from spring frosts. This is especially effective for early ripe varieties of peaches, plums, apricots.
10. During the period when buds are forming on the trees, urea treatment solves the problem with many pests and various diseases.
11. Spring treatment of the garden with urea helps protect trees from frost.
12. Urea is useless in the fight against old stumps, it is not able to completely destroy them, but only contributes to decay.
13. Never mix urea with other fertilizers and minerals - chalk, simple superphosphates, lime.

Preparing the garden for cultivation

Before you start spraying the garden in the spring with urea, you need to consider some recommendations:

Processing the garden in the spring from diseases and pests with urea is carried out as follows:

Processing of fruit trees

1. You can start treating the garden with urea if you have properly prepared the trees for this - dug up the ground under them, removed frozen and damaged branches, whitened the tree trunks.
2. A sunny and, most importantly, calm day is suitable for work. If the weather is hot, then it is advisable to spray in the early morning or evening after sunset.
3. It is necessary to prepare the solution and carry out the spraying itself in protective clothing, mask, goggles and gloves.
4. Urea will be especially effective in the fight against insects in combination with copper sulfate - 700 g of urea, 50 g of copper sulfate and 10 liters of water. Such a composition solves two problems at once - it destroys pests and fertilizes the soil.
5. For spraying, it is best to use a special sprayer. With it, even very tall trees can be processed.
6. When processing trees, do not spare the solution, it is impossible to harm them.
7. The second processing of the garden can be carried out already during the flowering period of the trees, and the third immediately after the ovary of flowers.
8. If precipitation falls after spraying, it will be necessary to repeat the procedure, otherwise everything will be in vain.
9. Root feeding of fruit trees during the fruiting period is carried out in the following ratio: cherry and plum trees will need from 120 to 150 g per 10 liters of water; apple trees will require 230-250 g per 10 liters of water.
10. You can not prepare a solution, but pour dry urea, but in this case it is necessary to carefully water the trees with water.
11. In the case of feeding trees with organic matter, the application rate of urea must be reduced by 1/3 or half, it depends on the amount of organic feeding.

Treatment of other plants and shrubs

Surely, many gardeners grow in the garden not only fruit trees, but also other plants, shrubs, both fruit and ornamental. They are also treated and fed with urea, which is used both as a fertilizer and as a disease and pest control.

1. Active feeding of plants is carried out in case of nitrogen starvation, which manifests itself as follows:
   • the plant begins to lag behind in growth;
   • leaves turn yellow and curl into a tube;
   • flowering is weak, without ovaries;
   • fruits and berries appear in small quantities and quickly crumble.
2. For work, preferably morning or evening. No work is carried out during the rainy season.
3. To prepare the solution, you need 30-40 g of urea per 10 liters of water.

Norms for root dressing:

• for cabbage and onions of any variety, beets, tomatoes, sweet peppers and potatoes, take 20-25 g per square meter. m.;
• for legumes and cucumbers - 5-8 g per square meter;
• for feeding strawberries, blackberries, strawberries and vegetables such as cabbage, cucumber or tomato - 20-30 g per 10 liters of water. Under each bush or plant, 1 liter of solution is needed;
• gooseberries are fed in a ratio of 10 g per 10 liters of water;
• for currants take 20 g per 10 liters of water;
• squash, eggplant and zucchini require 10-12 g per sq. m.

Today, urea is the most popular means for feeding trees, shrubs and other plants - approximately 35% of all nitrogen-containing fertilizers. It can be safely called one of the most effective and safe, which confirms the high and ever-growing demand. The cost of carbamide is slightly higher than that of other nitrogen-containing fertilizers due to the fact that it is not natural, but is obtained as a result of synthesis from ammonia and carbon dioxide. But in this case I can safely say that the price justifies the quality.

In order to get a good harvest from your orchard, you need to work fruitfully in it throughout the current year, starting from early spring and ending in late autumn. One of these important activities, in addition to whitewashing and pruning trees, is their spraying, and carbamide (urea) is considered the most effective means for this. Treating trees with urea solves several problems at once. Today we will talk about the processing of fruit trees and shrubs in the spring with urea.

Characteristics of urea

Urea is one of the highest concentrations of nitrogen fertilizers - almost 46%. Some beginner gardeners confuse it with saltpeter, which can be harmful to tree foliage. Carbamide is produced in the form of granular crystals of white and yellowish tints, which have absolutely no unpleasant odor, dissolves in water without any problems (the process is faster in hot water up to +80°C) and is perfectly distributed on the treated areas. Due to its hygroscopicity, it must be stored in airtight containers. Gardeners value urea not only for its high nitrogen content, but also for the high absorption rate by plants. This is especially effective in the fight against harmful insects, when every minute is precious.

What is urea produced in

The product is produced by the method of synthesis from inorganic substances, it is a granular mass consisting of rounded milky granules, sometimes translucent. At present, industrial production of carbamide has been established in the form of tablets.

Urea can be purchased in the form of granules.

According to the chemical composition, urea consists almost half of pure nitrogen, which dissolves without residue in any liquids, including water.

The period of processing the garden with urea

Processing fruit trees in the early spring is much easier than after color. IN May Days pollinated urea will not be able to get on the upper branches of plants due to dense young foliage and will not destroy the foci of infection on the tops of the trees. The result will not be visible. If the garden, in general, consists of trees that allow urea to get through young foliage (for example, pears and plums), then late spring or even summer treatments will also be very effective.

Early spring spraying of the garden with urea is also aimed at combating hard spring frosts. The nitrogen contained in urea will slow down the metabolic processes of the tree for a couple of weeks and will not allow young foliage and delicate inflorescences to bloom ahead of time. Thus, frosts, which can cause irreparable harm to fruit trees, will pass by. This property is especially useful for gardens consisting of early ripe varieties of trees such as peach, plum or apricot.

Fertilizing fruit trees with urea

The moment for processing the garden is chosen as follows. If you notice ants in the root holes, then expect aphids to appear soon. The moment of truth is coming, because this pest can not only deprive you of the harvest, but even destroy the tree. Time to get started:

Prepare the plants as mentioned earlier (digging the ground, cleaning the bark from damage and insects, whitewashing the trunk and skeletal branches).

For spraying trees, choose a sunny, windless day. If it is very warm, work early in the morning or in the evening, after sunset. If precipitation has passed after spraying the trees, re-treatment is required.

Spraying trees and mixing the solution should be done only in protective clothing, gloves and goggles. Use a backpack sprayer with an extended lance for tall trees.

No need to save money, it does not harm the plantings.

During fruiting, feed the plants with an aqueous solution at the roots. Apple trees - at the rate of 230 - 250 g of urea per 10 liters of water, plums and cherries - 120 ... 150 g. Carbamide can be applied dry at the root, then water the tree abundantly.

With the simultaneous introduction of organic matter (manure), reduce the rate of urea by 1/3 or even half.

Treatment with urea from pests

Spraying with urea effectively helps in the fight against plant pests. Spraying is carried out in the spring, when a constant average daily temperature of +5 C is established. It is important to carry out the procedure before the awakening of the kidneys, then all pests wintering in the scales and under the bark will be guaranteed to be destroyed.

A solution of urea for pest control is prepared at a concentration of 50 to 70 g per 1 liter of water. Spraying with urea helps to destroy aphids, weevils, copperheads and a host of other pests.

Latest articles about gardening and gardening

In autumn, at the time of the first stage of leaf fall, it is useful to spray trees with urea solution on which traces of infectious diseases are noticed: scab, all types of spotting, rust and others. Trees are treated with a solution along the crown and leaf litter. Such treatment is a very effective remedy for infectious diseases of garden trees, the garden next year will not be affected by infections. Simultaneously with the treatment, the urea solution fertilizes the plants.

Urea Precautions

When working with carbamide, a number of rules should be observed so that the procedure is effective and does not harm human health. Processing is carried out after preparing the garden: fallen leaves are collected, dry branches are cut, dead bark is removed. Work is carried out only on a calm day, early in the morning or in the evening before sunset. If it rains in the next 2 days, the garden treatment will need to be repeated. It is necessary to carry out work and dilute the solution with gloves, a mask and goggles. For work, a special sprayer is used so that it is possible to process the upper branches of trees. At the end of the work, you must thoroughly wash your face and hands, wash your work clothes immediately.

• Spraying trees and shrubs with carbamide requires pre-training. Under trees and shrubs, you need to dig up the ground, remove excess or diseased branches, be sure to whitewash the trunks.
• You also need to be aware of the weather. The day should be sunny, but not hot and, if possible, windless.
• Spraying with urea in the spring requires safety precautions: gardening is carried out in a respiratory mask, glasses and gloves.
• If your garden suffers a lot from pests, then to increase the effectiveness of urea, you need to add copper sulfate to it. In this case, 700 g of carbamide and 50 g of copper sulfate are needed for 10 liters of water. Moreover, this solution is completely harmless to both trees and shrubs. Therefore, the treatment of the garden with urea with vitriol should be done generously. Do not spare the solution, because it not only protects the trees, but also fertilizes the soil. It will be possible to process the garden for the second time during flowering, and for the third time - after the formation of ovaries.
• Try to match the weather so that after spraying there is no precipitation for several days. If it still rains, then the treatment of trees with carbamide must be repeated.
• If your garden does not have problems with diseases and pests, then it is not necessary to prepare a urea solution. Carbamide can be applied as a root dressing. Just pour dry urea into the hole with a tree or shrub and water it abundantly.
