Urea for fertilizing flowers. Urea: fertilizer, use in the garden Urea for vegetable crops

An experienced gardener and gardener does not forget to use various fertilizers for his plants to help grow healthy, fertile plants. It is especially important to fertilize the soil for the plant in spring and autumn. On the modern market you can find many types of “feeding” for plants and soil. Urea is in particular demand - it is also called urea. As with all fertilizers, urea must be applied correctly so as not to harm the plant. Read the detailed instructions for using urea in the garden.

Among the variety of fertilizers for the garden and vegetable garden, used both in spring and autumn, carbamide or urea is widely known. This fertilizer is in the form of white granules, containing 46% nitrogen. Urea is the richest nitrogen-containing fertilizer, has good solubility and is characterized by the absence of any odor. As the temperature increases, the solubility property increases. It is easy to appreciate the importance of using urea in gardening and gardening, knowing the importance of nitrogen fertilizer for all types of plants.

Urea fertilizer is used for:

• growth activation,
• obtaining abundant harvests,
• keeping plants healthy.

Urea is a good helper in the garden. Thanks to this approval, plants gain color well, have a bright green color, and bring a rich harvest.

It is worth taking the treatment of soil and plants with urea more seriously. A lack of nitrogen leads the plant to a depressive state, the appearance of barren flowers, and, accordingly, a poor harvest. Some plant species may simply die due to lack of nitrogen. It is also important not to overdo it with urea fertilizer. An excess of nitrogen also negatively affects plant development. It is worth carefully familiarizing yourself with the dosage of urea for each type of plant.

Urea - instructions on how to apply fertilizer correctly

The best time to treat the soil with urea

The best time to add urea to the soil is the period of flowering of garden plants and before fruiting of garden crops.

By this time, the soil is sufficiently depleted, and signs of nitrogen deficiency in plants are most clearly visible. It is worth choosing calm weather after heavy rainfall: this will allow nitrogen to penetrate into the deeper layers of the soil. There is no point in using urea before planting, since nitrogen particles are quickly washed out of the soil by precipitation.

When does a plant need urea fertilization?

During the development of a plant, it is important to pay close attention to its appearance. The condition of the plant will indicate the need to apply fertilizer. Having decided to use urea, you need to make sure that nitrogen fertilizers are necessary. Lack of nitrogen affects the appearance of the plant:

1. The plant remains in the sprouting stage for a long time (does not grow into a mature plant);
2. A mature plant has small shoots and bare branches;
3. The leaves are unformed, have white pigmentation, and often fall off.

If the plant does not have the above signs, grows well and has a rich green color, do not rush to fertilize with urea.

Urea can also be used to prevent a lack of nitrogenous elements in the soil. There is no need to wait for obvious signs of nitrogen deficiency. Prevention will help improve the condition of plants and prevent a decline in yield.

What causes excessive application of urea?

Any fertilizer is good in moderation. Excessive enthusiasm for “feeding” plants can lead to negative consequences. Strict compliance is required: fertilizer proportions, time of application to the soil, and most importantly, the need for fertilizer. Excessive enrichment of the soil with nitrogen can lead to a deterioration in the condition of the plant, affecting its fruiting and growth. The death of the entire plant is possible. In order not to harm the plant, you should carefully read the detailed instructions for using urea as a fertilizer.

How to use urea as a fertilizer

Urea is widely used both in the garden and in the vegetable garden. It is suitable for fertilizing all plants. The ways of using it are also varied:

1. Urea solution. A certain amount of urea is dissolved in water and the soil near the plant is watered.
2. Application in the form of granules. Granules are introduced into the soil at a shallow depth, into pre-moistened soil.
3. Fertilizer during planting. When planting a plant, several urea granules are placed in the hole.
4. Spraying plants. Urea is dissolved in water, after which the plant itself is processed.

The variety of ways and ease of use of urea gives it an advantage over other fertilizers.

Fertilizer dosage for different crops in the garden

1. Fruit trees

Feeding trees with urea is an important procedure in every garden. No matter how fertile the earth is, over time its beneficial substances are washed out, dissolved and disappear. To get a wonderful harvest with large ripe fruits, it is necessary to spray the garden with urea.

Fruit trees should be fed with urea three times per season:

1. Spraying trees when the first greenery appears in early spring
2. Application to the soil in the form of a solution during flowering
3. Application to the soil in the form of granules during fruit ripening.

When using urea as bait, you should adhere to the following tips:

• Apple trees need to be fertilized in early spring after the first heavy rainfall. The soil should be completely thawed and well moistened, allowing nitrogen to easily penetrate the soil.
• It is worth retreating 0.5 meters from the tree trunk, trying to spread the urea under the tree crown. The foliage of the tree will create a shadow barrier, thereby preventing the rapid breakdown of nitrogen into microelements from sunlight.
• Urea is not used mixed with other types of nitrogenous fertilizers; they can react with each other and harm the tree.

For each type of tree, there is its own fertilizer rate:

Apple tree

Apple trees are unpretentious and resistant to various climate changes. They can fully develop on poor soil surfaces. But to obtain a high-quality harvest, you still need to take care of apple trees.

SPRING	In early spring, feeding apple trees is done in the form of adding granules to the soil. A certain amount of granules is introduced into the soil, after making a small depression. If you measure the number of urea granules in grams, you get 150 g per tree. After adding granules, the soil is moistened.
SUMMER	The most effective method of using urea for apple trees is to spray the trees. Spraying is carried out during the flowering of the apple tree, before the fruit sets. This way, the leaves of the tree quickly receive and absorb the nutrients introduced, as well as quickly provide assistance to an already sufficiently damaged plant. For young apple trees use 0,3% urea solution, and for mature trees 0,5% solution. The apple tree has large fruits, thus requiring a higher concentration of urea compared to other trees.
AUTUMN	In the autumn, you should refrain from feeding apple trees with urea. The concentration of nitrogen in winter reduces the winter hardiness of the apple tree. This can lead to deterioration of vegetative function and lack of fruits.

Pear

Pear trees have few differences from apple trees. They are similar in structure, since they belong to the same family, and thus the features of caring for them are the same. But there are also some differences.

SPRING	In the spring, pears require three times of enrichment with nitrogen-containing fertilizer. — We make the first complementary feeding during the period of kidney swelling. Root feeding is introduced. Just like apple trees, pear trees should be fed after the first rainfall, adding fertilizer to moist, loosened soil. The quantitative composition of fertilizer applied to the soil for pear-shaped trees is 100 grams per tree. Fertilizing with urea improves the root saturation of the pear with useful substances. — After the first inflorescences appear, the pear should be fed a second time, which completely repeats the first. Nitrogen will help the tree produce as many flowers as possible and prevent them from falling off. The main thing is not to miss the moment. When the inflorescences fully open, a third fertilization with urea is carried out. — Fertilizing pears during the fall of the ovaries allows you to improve the quality (both external and taste) of pear fruits. The third time, a smaller amount of urea will be used so as not to harm the tree. The dosage of urea is reduced to 50 grams, or even 30 grams per tree. It is important to moisten the soil well and retreat 0.5 meters from the tree trunk.
SUMMER	In the summer, foliar feeding of the pear tree should be carried out - spraying the tree crown. In severe drought or, conversely, rainy summer, spraying will help quickly deliver nitrogenous substances than with root fertilization. Added to the sprayer solution of 100 grams of urea per 10 liters of water and the pear tree is processed with it. It is especially important to feed the pear in summer if signs of nitrogen deficiency are clearly visible.
AUTUMN	A pear, like an apple tree, should not be fed with urea in the fall.

Cherry

The cherry tree has a weaker root system compared to apple and pear trees, so the method of applying fertilizer will be different.

Plum

Plum trees, due to their unpretentiousness, need minimal fertilizer: they only need microelements in the soil. But for prevention, it is still worth using fertilizers.

Apricot

Apricot is a rather whimsical tree. Often it does not take root, and having taken root, it produces meager, often spoiled, fruits. To avoid failure with growing apricots, you should carefully consider its fertilizer. To strengthen and grow the apricot, as well as for good fruiting, the tree is fertilized with urea.

Urea is the main assistant to any gardener, which helps to obtain a high-quality harvest and maintain the healthy appearance of trees.

1. Vegetables

Caring for vegetable crops differs from fruit and berry crops. This is due to their undeveloped root system, thin and low stem. Also, almost all vegetable crops are annual, which determines their peculiarity in cultivation and fertilization. Urea is used to fertilize vegetables only once during the entire season and only before the fruits ripen. The method of using urea is different for each vegetable:

Type of vegetable	Fertilizer time	Mode of application	Dosage
Garlic	growing season	Root	Potassium chloride is added to urea - 10 g of urea, 10 g of potassium chloride per 10 liters. water
cucumbers	growing season	Watering solution	15 g of urea per 10 liters. water with the addition of 60 g of superphosphate.
Tomatoes	During disembarkation	The granules are placed in the hole	15 g of urea with the addition of 60 g of superphosphate
Cabbage	growing season	Root	A solution of 30 g of urea per 10 liters. water
Potato	Fertilize the soil before planting	Granules are placed in the soil	For 1 hectare of land, 2 kg of urea.

You should be more careful about vegetable crops and their fertilizers. It is better to fertilize the soil before planting vegetables so that the chemical concentrate has time to dissolve.

The difference between urea and ammonium nitrate

Urea is the main type of fertilizer containing nitrogen in its composition. But there are other nitrogen-containing fertilizers. Among them, ammonium nitrate (ammonium nitrate) is widely known. Despite the similarity of the composition, which includes nitrogen, they have clear differences:

	Urea	Ammonium nitrate
Nitrogen percentage	46%	35% (maximum)
Mode of application	Urea is practically safe to use and has no special storage conditions.	Root only
Chemical composition	Organic compound	Mineral compound
Degree of usefulness	Reacts faster and retains nutrients in the soil longer	Long period of decomposition into microelements, rapid leaching from the soil
safety	Root and foliar	Ammonium nitrate can cause chemical burns (to both humans and plants). The composition is explosive and has special storage conditions

Despite the cost-effectiveness of using ammonium nitrate as a fertilizer, which is cheap and economical in consumption, experienced gardeners prefer urea fertilizer. Due to its explosive nature, ammonium nitrate is difficult to purchase on the regular market, which makes urea very popular among gardeners.

Pros and cons of feeding plants with urea

Urea is one of the most used fertilizers in gardening. In the garden, urea is also irreplaceable and is used everywhere. Like any fertilizer, urea has both beneficial and negative properties:

Advantages of urea as a fertilizer

1. Contains a high concentration of nitrogen 46%, compared to other nitrogen-containing fertilizers;
2. Easily dissolves in liquid and mixes with other types of fertilizers;
3. The chemical composition of urea enriches the soil with microelements;
4. Indispensable in sandy areas;
5. Microelements of urea do not sink into the deep layers of the soil;
6. It quickly reacts with soil bacteria and breaks down into microelements.

Disadvantages of urea as a fertilizer

1. Reduces acid concentration in the soil;
2. Rarely used in autumn, only for some plants;
3. Easily washed off by precipitation and quickly dissolved by sunlight;
4. Has a short shelf life;
5. Excess urea leads to the death of the plant.

Despite the disadvantages of urea as a fertilizer, it is practically impossible to replace it with another nitrogen-containing fertilizer. Ease of use, minimal harm to the plant, and most importantly organic origin are the main advantageous advantages of urea as a fertilizer.

It is quite difficult to grow a healthy plant in the garden and get a rich harvest without the use of additional nutrients. Vegetables, fruits and berries, flowers and trees need fertilizers. Fertilizing with Urea or Urea is recognized as the most practical and effective in agriculture. These are white granules with a grayish or yellowish tint. The use of Urea fertilizer is of decisive importance for plant development and crop ripening.

Description of the fertilizer

Urea The traditional appearance of the fertilizer is white granules with a yellowish or grayish tint. However, recently Urea has appeared in specialized stores in tablet form. Urea tablets are coated with a layer of long-soluble substance, due to which the process of interaction of fertilizing components with the soil significantly slows down. Consequently, the concentration of nitrates in plants and crops remains within normal limits.

The main difference between Urea and other nitrogenous fertilizers is the high concentration of active substances. As a result of contact with microorganisms contained in the soil, Urea is transformed into the ammonia form of nitrogen, and then into the nitrate form.

The nitrogen content in the fertilizer reaches 46%; it is most effective when used in liquid form, in which case the active chemicals do not burn the leaves. Nitrogen is used by agronomists to control plant growth. Despite the fact that agricultural crops use this substance sparingly, regardless of the composition of the soil, it is nitrogen that is most deficient. When added to the soil, plants absorb no more than half of the total volume, the rest evaporates during the decomposition process or is washed away by precipitation. It is the mobility of nitrogen that leads to its lack in the soil and inhibits plant growth.

Benefits of Urea

• The granules dissolve quickly and without sediment in water.
• Nitrates, provided the fertilizer is used correctly, do not accumulate in the crop.
• A rapid increase in vegetative mass is observed.
• The protein content of cereal grains increases, and the yield of all agricultural crops increases.

Flaws

• When preparing the solution, you need to take into account the temperature difference between the fertilizer and the air. During the dissolution of granules in water, an endothermic reaction occurs, as a result of which the finished solution cools. If you dissolve 20 kg of Urea in 100 liters of water, the solution will become colder by 9 degrees. Treatment with such fertilizer will cause stress to the plants. The permissible difference between the temperature of fertilizing and air is no more than 10 degrees.
• If the concentration indicated on the package is not observed, burns appear on the leaves and roots, which can lead to the death of the plant. First of all, this concerns feeding young seedlings and seedlings.

If the nitrogen deficiency is too high and it is necessary to increase the concentration of the solution, magnesium sulfate is added to it at the rate of 3 kg per 100 liters. This component neutralizes the burning effect of nitrogen and protects plants.

Note: Nitrogen is critical for plants and future harvests. It is this substance that takes an active part in the construction of molecules, as it is a component of plant protein. That is why stimulating plant growth with Urea is a prerequisite in the garden to obtain a high yield.

Compound

Do you dream of a lush, healthy garden and a tasty, rich harvest? Provide plants with protein, which is found in abundance in Urea and Urea. The composition of the fertilizer is 46% nitrogen. Top dressing is suitable for any plants and soils. The granules dissolve quickly and without sediment in water, the solution is odorless.

To make Urea, carbon dioxide and ammonia are used, which are subjected to pressure and high temperature. As a result, small crystals are formed that have minimal hygroscopicity.

Nitrogen is presented in Urea in an easily digestible form, thanks to which active nutrition of the leaves and root system occurs. The chemical process of interaction between Urea and soil is long, so the fertilizer is absorbed evenly by plants.

Note: During the formation of granules, a small amount of biuret is released. This is a toxic substance, but the total mass of the fertilizer contains no more than 1%; biuret will not cause harm to the plant.

If the storage conditions are met, the shelf life of Urea is unlimited, however, the warranty period provided by specialized stores is no more than six months. After six months, the concentration of the active substance decreases slightly, which transforms into ammonia and evaporates. The same chemical reaction occurs due to improper storage. If Urea is stored in a room with high humidity, the fertilizer granules stick together and harden.

Instructions for use

First of all, it is necessary to determine whether the plants in the garden have enough nitrogen fertilizers. The lack of this substance affects as follows:

• plants develop unharmoniously and for a long time;
• shoots are weak, crown is sparse;
• the leaves are small, pale, and fall off quickly.

It is also important to promptly determine excess nitrogen:

• at the very beginning of vegetation development, the plant develops very slowly;
• then rapid growth of the crown is observed;
• leaves become dark green;
• fruits ripen faster, but at the expense of shelf life;
• the harvest is less juicy and not as flavorful.

The application of Urea is justified during the flowering period and before fruiting. Traditionally, granules are scattered on the site in a certain proportion, sprinkled with earth on top, the surface is leveled with a rake and watered abundantly. This arrangement minimizes the evaporation of ammonia, which is formed as a result of the interaction of granules with bacteria and enzymes in the soil. It is better to apply Urea in cloudy weather, after good rain. Burying the granules is also necessary to ensure that precipitation does not wash them away from the surface of the site.

The tablets have the longest shelf life, this is due to the fact that according to the production technology they are coated with a special layer that slows down the process of dissolution of the fertilizer.

There is a certain scheme for applying Urea; it is important to adhere to these recommendations, since otherwise the plants and crops accumulate excess amounts of toxins.

Feeding fruit trees

• The first feeding occurs at the stage of formation of buds and first inflorescences.
• The second feeding is carried out at the initial stage of fruiting.

Urea is actively used in the fight against insects and pests. This treatment is most effective against apple blossom beetle, aphids, honeyweeds and weevils. Insects become active when the air temperature rises to +5 degrees, so it is advisable to treat trees during the period of bud formation on the trees. To prepare the solution, add 0.5 kg of granules to a bucket of water (10 liters). Spraying is carried out in late autumn, after the trees have shed all their foliage. The prepared solution is enough to treat an area of ​​ten square meters. You should not spray trees that remained clean in the summer and were not attacked by insects.

Note: vegetable crops cannot be treated with Urea solution - the active substances of the fertilizer burn the leaves and the plant may die.

To feed fruit trees, prepare a solution as follows: dissolve one tablespoon of Urea in one bucket of water (10 liters) and treat one square meter of area with the resulting solution. The mixture is sprayed around the tree trunk, then the area is leveled with a rake. This feeding is carried out in the spring. If necessary, you can repeat feeding twice more:

• at the beginning of fruit formation;
• when the first fruits begin to fall.

Fertilizing of vegetable crops, bushes and flowers

A week before the start of sowing and planting, Urea granules are applied to the soil to a depth of 8 cm. Less deep fertilization of the site will result in some of the nitrogen being transformed into ammonia and evaporating.
Directly during planting and sowing work, urea is poured into the holes, but in this case, an earthen layer must remain between the root system of plants or seeds and fertilizer.
Application of Urea in liquid form to plants is most effective in comparison with fertilizing with other fertilizers with a similar composition. In this case, the active substance does not burn the leaves.

Note: maximum efficiency and safety of Urea can be achieved only if the technology for its application is followed, namely: correct preparation of the solution, compliance with proportions and combining the feeding procedure with watering.

When application is not effective

Autumn application of Urea to the soil is impractical. During this period, microorganisms decompose in the soil, and ammonium is also destroyed.
In early spring, before the start of the growing season, it makes no sense to feed the soil with Urea, since the granules are quickly washed away by rain and do not enrich the soil with nitrogen.

Fertilizer concentration

The concentration of fertilizing depends on several factors:

• fertilizer application method;
• degree of soil moisture;
• chemical composition of the soil.

Note: an excess of Urea has a negative impact on the yield, so it is important not to apply fertilizer during the period of active fruiting of plants.

What can be fertilized

The main condition for using Urea is strict adherence to the dosage. Especially when it comes to feeding vegetable crops, which are very susceptible to the application of various fertilizers.

Generalized instructions for using Urea

Type of work	Dosage	Special Recommendations
Application to the soil in the form of a solution	200 grams of urea per 10 square meters of land	Fertilizer is used for areas where vegetable, fruit and berry plants and flowers grow. This fertilizer is most effective for tomatoes, potatoes, garlic, strawberries and rose bushes.
Application to the soil in the form of granules	For 10 square meters of area from 50 to 100 grams of granules	The fertilizer is deepened into the soil by 8 cm and watered abundantly with water.
Planting work	4 grams per well	The granules are thoroughly mixed with the soil to prevent direct contact of the root system with the fertilizer.
Fertilizing trees	The amount of Urea varies depending on the size and type of tree - from 100 to 250 grams per trunk	For non-fruiting apple trees - 150 grams. For apple trees that bear fruit - 250 grams. For non-bearing cherries and plums – 100 grams. For cherries and plums that bear fruit - 140 grams.
Feeding bushes	70 grams for each bush	The fertilizer is scattered around the trunk, thoroughly covered with soil and watered. The diameter of fertilizer application is calculated based on the size of the plant’s root system.
Liquid fertilizer for vegetable crops	3 grams of Urea are dissolved in 1 liter of water	The solution is used to feed tomatoes, cabbage and strawberries. One liter is enough for one bush. During the formation of the ovary, you can increase the concentration to 5 grams per liter.
Spraying plants	The concentration of the solution is no more than 1%; to prepare, 10 grams of granules are dissolved in 10 liters of water	This volume is enough to process 20 square meters of land.

How to dilute for treating fruit trees against diseases and insects

To combat scab, monilial burn and purple spot, dilute 0.5 kg of granules in 10 liters of water and spray the plants at the end of summer, before dropping the leaves. Treatment can be carried out in late autumn, before the first frost, but in this case 0.7 kg of granules will be required per bucket of water. If trees are treated at the rate of 250 ml of solution per square meter, pests will be destroyed.

Note: you need to be creative when preparing the solution. If the weather is sunny and hot, it is better to reduce the concentration to a minimum.

Price

Fertilizer sales are increasing annually, since Urea is the most popular and in demand fertilizer. The cost of pellets depends not only on packaging and manufacturer, but also on seasonality. Therefore, experts recommend purchasing fertilizer in advance, in this case you can save your budget.

You can purchase fertilizer in bags:

• 1 kg – from 70 to 90 rubles;
• 3 kg – from 150 to 170 rubles;
• 50 kg – from 1000 to 1250 rubles.

Urea is also sold by railcar:

• - 1 ton - from 19 to 19.5 thousand rubles;
• - 20 tons of fertilizer cost an average of 250-260 dollars.

Physical and chemical properties

Urea (pure form)

- colorless, odorless crystals.

Urea (fertilizer)

- colorless granules ranging in size from 1 to 4 mm. The mass fraction of nitrogen in terms of dry matter is 46.2%.

Application

Two grades of urea are produced: A - for industry and B - for crop production.

Agriculture

Urea brands registered and approved for use in agriculture in Russia are listed in the table on the right.

Industry

Urea is used in industry as a raw material in the production of resins, adhesives, and also in animal husbandry as a feed additive.

Behavior in soil

Urea in the soil is dissolved by the soil solution and, under the influence of urobacteria that secrete uraza (a special enzyme), ammonifies in two to three days and turns into ammonium carbonate:

CO(NH 2) 2 + 2H 2 O → (NH 4) 2 CO 3

Ammonium carbonate is an unstable compound; it decomposes in air, forming ammonium bicarbonate and ammonia:

(NH 4) 2 CO 3 → NH 4 HCO 3 + NH 3

For this reason, when urea is applied without incorporation into the soil in the absence of precipitation, part of the nitrogen in the form of ammonia is lost. Such losses are more significant in soils with neutral and alkaline reactions.

Ammonium carbonate embedded in the soil undergoes hydrolysis. This produces ammonium bicarbonate and ammonium hydroxide:

(NH 4) 2 CO 3 + H 2 O → NH 4 HCO 3 + NH 4 OH

The ammonium formed when carbamide is added to the soil is absorbed by the colloidal fraction and is gradually absorbed by plants. It has been established that urea can be absorbed by the roots and leaves of plants without prior conversion. But there is a danger of urea that has not undergone ammonification being washed out of the soil.

As urea ammonification progresses, temporary local alkalization of the soil occurs due to the hydrolysis of ammonium carbonate. After some time, ammonium undergoes nitrification, forming acid and moving the reaction towards acidification:

2NH 3 + 3O 2 → 2HNO 2 + 2H 2 O

2HNO 2 + O 2 → 2HNO 3

Thus, urea is a biologically acidic fertilizer. But after the plants absorb the nitrogen from this fertilizer, there are no acidic or alkaline residues left in the soil.

Application on various types of soils

Urea is used as the main fertilizer on all soils for various agricultural crops.

On light soddy-podzolic soils

in zones of sufficient moisture and during irrigation on gray soils, urea is more effective than ammonium nitrate.

In rainfed conditions

when urea is equivalent to ammonium nitrate.

On soils with neutral and alkaline reactions

When applying, it is necessary to immediately incorporate urea into the soil to reduce nitrogen losses.

Methods of application

Urea is used before sowing and in.

As the main fertilizer, urea is used on all soils and for all agricultural crops.

Early spring winter cropping is carried out with immediate incorporation of fertilizer into the soil by harrowing in order to reduce ammonia losses.

Vegetable and row crops are carried out using cultivators-plant feeders.

Urea is considered the best form of nitrogen fertilizer for plants because it does not burn the leaves and is able to be absorbed by them as a whole molecule, without decomposition.

An old and time-tested fertilizer urea (urea) is used everywhere and is considered universal. In addition, it is part of multicomponent mixtures intended for complex treatment of fields and garden plots. This tool is one of the most popular and widespread options, and its cost is very affordable.

Composition of urea fertilizer

The chemical composition of this fertilizer has not changed for years. It is still a chemical that is 46% nitrogen. From a chemical point of view, it is a carbonic acid amide. It is formed under high pressure from carbon dioxide and ammonia gas. In the finished state, the fertilizer is a water-soluble crystallized substance of white color, sometimes with a yellowish tint. Available in the form of granules, packaged or weighed.

Like all fertilizers with a high nitrogen content, urea improves plant growth, increases productivity, and increases the protein content of grain crops. The peculiarity of this drug is also that it can be used as a means to combat plant diseases and wintering insect pests. These insects include the following species:

• apple blossom beetle;
• slowpoke;
• weevil.
  Among the diseases effectively eliminated:
• Scab;
• Purple spotting;
• Monilial burn.

How to dilute urea for irrigation

Since urea is soluble in water, it is convenient to apply it by watering plants. But it is important to maintain concentration. For strawberries, cabbage, tomatoes and cucumbers it is 20-30 grams per 10-liter bucket. You will need to apply 1 liter of this solution per plant. The same solution is applied under currant bushes, and gooseberries will require a concentration twice as low.

Instructions for use of urea fertilizer

Urea is widely used in dry form, as well as. When sowing vegetable crops, 3-4 grams of the drug are poured into the garden bed and mixed with the soil. Mature trees, including cherries and plums, are fed with 120-140 grams of fertilizer. For apple trees, the dose is doubled. Urea is sprinkled on the surface of the soil and then the plant is watered.

Spraying with a solution is also widely used. This is done during the active growing season of vegetable crops, but before flowering begins. The concentration of the solution is 50 grams per 10 liters. But the amount of sprayed solution is only 3 liters per hundred square meters.

Application of urea fertilizer in spring

For each fertilizer, the timing of its application is important. Urea can be applied when planting potatoes and other crops, usually in mid-spring. But the treatment of trees and shrubs to protect them from pests is done a little earlier. This needs to be done before the buds open, and you can start immediately after the air temperature rises to +3-5 degrees. The solution must be concentrated (I use 0.5-0.7 kg of the drug per 1 liter of water).

In parallel with urea, you can also use insecticides, for example.

To ensure human life, food is needed, and flowers need fertilizer. To enjoy the growing process and the results in the form of lush greenery, abundant flowering, and most importantly, a healthy plant with a bright color, you should know the type, dosage, and feeding rules.

Urea (urea) is a well-known fertilizer that contains the maximum amount of nitrogen compared to other minerals.

Urea is packaged in convenient polymer bags, sometimes paper or laminated containers are used. This form of release is due to the fact that the urea does not cake.

You can even store it in the fresh air; the most important thing is that it is moisture-proof; urea should not be allowed to mix with other components. Shelf life - no more than two years.

When using nitrogen make-up, you should not neglect basic protective measures to avoid burns or poisoning:

• rubber (cotton with rubberized fingers) gloves,
• respirator or gauze bandage;
• workwear.

Urea: pros and cons as a fertilizer for flowers

Urea is an inorganic fertilizer that is gradually absorbed by plants and is the leader in nitrogen content - 46%.

Main advantages:

• it takes virtually no time for plants to absorb nutrients;
• easily absorbed;
• rapid dissolution in water;
• rich color of green mass (dense stems, bright leaves);
• active formation of buds (flower buds), lush flowering;
• ensuring rapid growth;
• urea is convenient for nutrition (feeding) because it is used in the form
  granules;
  liquid solution;
  soluble tablets;
• actively and quickly interacts with soil enzymes and bacteria.

The disadvantages include:

• quick solubility is not always good, because it easily disappears with groundwater;
• strict dosage is necessary, otherwise it causes the destruction of soil microflora;
• Excessive consumption of the nutrient can turn part of the fertile soil into ammonia.

How to improve productivity?

We are constantly receiving letters in which amateur gardeners are worried that due to the cold summer this year there will be a poor harvest of potatoes, tomatoes, cucumbers, and other vegetables. Last year we published TIPS on this matter. But unfortunately, many did not listen, but some still applied. Here is a report from our reader, we would like to recommend plant growth biostimulants that will help increase the yield by up to 50-70%.

Urea: proper use for fertilizing flowers

In order for flower crops to have a bright color and enjoy active growth, you should create a balanced diet for them from various fertilizers, providing appropriate care. At the same time, we should not forget that the soil must be enriched with microelements, and if ornamental crops grow in one place for a long time, they deplete the soil’s useful resources. Therefore, you should not forget to plan your garden, taking into account the availability of places for replanting or planting flower crops, fertilizing the plots of land where you plan to plant the plant, and using regular fertilizing. With such an integrated approach, the garden will have a rich color and pleasant aroma.

Nutrition of ornamental plants is applied taking into account individual needs and subject to basic rules.

Annual plants:

• application of fertilizing 2 times during the season;
• the first time 10-15 days after planting, so that the seedlings take root;
• the second feeding at the time of bud formation and formation.

These simple rules will ensure full development, bright color and lush flowering.

Perennials:

• annually 3 times per season;
• first fertilizing in spring in loosened soil;
• the second - at the time of flower bud formation;
• After the plants have flowered, they should be fed to give them strength for the winter, as well as to ensure strong, healthy buds for next spring.

It is worth knowing that seemingly universal organics are not always suitable for some flower whims:

• asters,
• nasturtiums,
• marigold,
• hyacinths,
• lilies,
• daffodils,
• daylilies,
• tulips.

It should be noted that indoor bulbous ornamental plants should also not be fed with organic matter. Its use leads to various diseases and death. Urea will always come to the rescue, which will ensure the full development of plants and bright color.

Ornamental deciduous plants are especially grateful to urea, because due to the high nitrogen content, green mass increases during the period of active development.

Surface feeding method (pellets):

• scattering of granular crystals over the surface of the earth;
• only around the root system of the plant without direct contact with the roots, otherwise burns may be caused;
• lightly sprinkling with soil to avoid evaporation of some of the nitrogen;
• leveling the layer with a rake;
• mandatory watering of the flower bed.

Burying the granules is necessary if the soil is too wet to prevent them from being washed away from the fertilizing site during gusts of wind or heavy rain. This method ensures a rapid response of the beneficial properties of urea.

If the soil is heavy, then you should use about 25 grams to feed 1 square meter. m. of land.

Use of tablets:

• bury the tablet in the soil in close proximity to the root;
• the tablet dissolves more slowly, resulting in an increase in the temporary interaction of the plant and beneficial properties.

Pest control using a solution:

• urea is used as a spray;
• strictly adhere to the rules for diluting urea with water;
• for pest control, a precise dose of urea per 10 liters of water is 400 grams:

1. for wintering pests, spray in early spring until the buds swell;
2. in summer, if there are signs of nitrogen starvation, spray immediately;
3. in late autumn, in order to get rid of various pests that have accumulated over the summer, at the same time treat fallen leaves.

• during the development period, you can actively, but maintaining concentration, use urea for successful flower vegetation (laying flower buds, growth);
• a few hours before feeding, it is worth watering the plants;
• Do not feed dormant, sick or recently planted, unrooted flowers;
• feed seedlings, as well as young plants, using a less concentrated solution;
• shady flower beds are less likely to need fertilizing;
• heat and sunny days are bad helpers for nitrogen nutrition.

Features of feeding indoor flowers:

• fertilize depending on the time of year:

1. winter – once a month,
2. spring - summer - weekly,
3. autumn – once every 2-3 weeks;

• The growth rate of a flower crop matters:

1. fast growing – weekly,
2. slow - every month.

Foliar feeding by spraying a urea solution is carried out at the beginning of development to activate its growth. Prepare the solution required for treatment at the rate of 10-15 ml per flower crop and in the proportion of 1 liter of water per 7-10 grams.

When laying compost, you should pay attention to the materials of the laying. If these are materials that cause carbon reactions (sawdust, straw, leaves, grass, paper), which can heat up to 60 degrees in a heap, you need to add urea in a ratio of 1 kg/1 sq.m.

Urea as a fertilizer for indoor plants

If you carefully use urea according to the instructions, then even the most ordinary lawn with grass will delight you with bright and juicy greenery that retains its rich color for a long time.
