Why is urea dangerous as a fertilizer? Proper feeding of plants with urea. The principle of action of urea

All farmers, both experienced and beginners, know about urea (urea). This is a universal and highly effective fertilizer for the garden. Today we will tell you: what is urea, the rules for using it as a fertilizer, and how to fight pests in the garden using urea.

What is urea

Urea (urea)– nitrogen fertilizer in granules, which is widely used in gardening and gardening; moreover, it is inexpensive and accessible.

If you use the correct dosage of urea as a fertilizer for a particular crop, the plant will grow well, develop, and produce a lot of fruit.

Urea in its pure form is round white or transparent granules, and the fact that it is produced in granules prevents it from caking during transportation and storage. (NH 2) 2 CO is the chemical formula of urea, in which almost half, namely 46% of the total volume, is nitrogen.

Did you know?E927b is a food additive - urea, used in the production of chewing gum.

Important!Urea should be carefully protected from moisture during storage, as it is highly moisturized.

Signs of nitrogen deficiency in plants

In open-air soil, seedlings are exposed to various factors, even if they were strong at the germination stage. When there is not enough nitrogen in the soil, you will definitely see it in the plants, according to certain signs:

Important!An excess of nitrogen in plants is also very harmful; it can then be converted into nitrates, and an excess of nitrogen fertilizers in the soil leads to intensive plant growth with the formation of abundant greenery, but fruiting suffers.

Use of urea as fertilizer

Urea is suitable for all periods and methods of application (during sowing, before sowing, during the growing season of plants, foliar feeding before fruit set).

Urea is used as the main fertilizer before planting on all types of soils and for feeding vegetable, ornamental and fruit crops. Can also be used in protected ground conditions.

Interesting fact!The name of the football club "Amkar" from Perm is an abbreviation of two chemical substances: ammonia and urea.

Root feeding

Often, root treatment of plants with urea means that it is introduced into the ground superficially, with further incorporation to different depths.

Simply scattering urea granules during rain will not bring much benefit, therefore, it is best to use local application - a pre-made urea solution for garden seedlings is poured with a watering can as close to the roots as possible.

For strawberries, cucumbers, tomatoes, cabbage, the solution is made at the rate of 20-30 g of urea per 10 liters of water, for gooseberries - 10 g of urea per 10 liters of water, and for currants - 20 g of urea per 10 liters of water.

The second method is also used - digging holes or small holes into which urea granules are thrown, covered and watered. The first option is best used in dry weather, and the second in rainy weather. For fruit and berry plants, urea is applied according to the projection of their crowns.

Important!If the trees are young and do not bear fruit yet, then the amount of urea should be reduced by half, and if organic matter is used - by at least a third.

Foliar treatment

As soon as the first ones become noticeable signs of nitrogen starvation in plants, it is imperative to carry out foliar treatment by spraying plants with urea solution using a hand sprayer in the evening or morning.

If you don’t have a sprayer, you can do the treatment with a simple broom. A solution for fertilizing vegetables is made at the rate of 60 g of urea per 10 liters of water, and for fruit and berry crops - 30 g of urea per 10 liters of water, and this solution does not burn the leaves, which cannot be said about ammonium nitrate.

Important!If there is precipitation outside (for example, rain), then urea cannot be used for foliar feeding.

Urea against pests in the garden

Urea has also found its application in gardening and gardening as good assistant in pest control, and if there is no desire to use various pesticides, then it will be just right.

Urea is amides of carbonic acid, which are colorless, odorless crystals. Among gardeners and gardeners, urea () is often used as a universal, highly effective granular nitrogen fertilizer.

The use of urea promotes the development and growth of plants and their abundant fruiting. has proven itself well among amateur gardeners.

1 How to use urea?

When using urea as a fertilizer in gardening or vegetable gardens, you need to take into account that in a few days it is modified and transformed under the influence of bacteria that are in the soil.

The best results are obtained by applying urea not only to gardening farms, but also to greenhouses. To achieve the maximum beneficial effect, urea must be quickly incorporated into the soil in order to reduce the loss of ammonium carbonate to a minimum. This action significantly increases the level of nutrients, namely nitrogen, entering the plants.

Urea can be used on any soil as a fertilizer or feed for garden and fruit plants. Although this product has versatility, it is still worth remembering that different crops need different amounts of fertilizer. Therefore, the nutritional supplement must be applied in certain doses depending on the plants.

Treatment of gardens and vegetable gardens with urea as a fertilizer during the growing season is used:

• for processing cabbage, peppers, onions, beets, tomatoes, potatoes and 19–23 g/m²;
• for feeding peas or cucumbers, add about 6–9 g/m²;
• for zucchini, eggplant and squash 10–12 g/m²;
• for grains 300 grams per hundred square meters in granular form;
• for protection against pests and diseases in the garden, foliar feeding of vegetable crops 9–15 g for every 10 liters. water;
• For . Fertilizer is applied to the soil before planting berries. Before the appearance of ovaries and buds, spraying with urea 10 g is used. for 2 liters of water. To increase the yield, fertilize with a concentrated solution of 60 g. for 20 liters of water at the beginning of September or at the end of August.

1.1 Application features, properties and consumption of urea as a fertilizer (video)

2 Fertilize the plants

To get a full harvest of cucumbers, you need to feed them. Without fertilizing, plants are prone to poor fruiting and early leaf loss.

Cucumbers can be fed from the beginning of seed germination until the period of fruiting. Plants are saturated with organic substances and beneficial elements. Urea is applied as a top dressing for cucumbers in a volume of 7-8 grams per meter of plot.

Fertilizer must be applied twice during the entire growing season. To increase productivity, cucumbers are fed with a concentrated mixture: 60 grams of urea per 20 liters of water.

2.1 How to dilute urea for garden treatment?

With the use of granules everything is clear, you just need to measure the required weight, and then apply fertilizer to the soil. Therefore, diluting urea requires special attention because many, especially beginning farmers, are interested in the question of how to properly make a solution of the required concentration from it.

2.2 Spraying the garden against pests in spring

Spraying the garden in the spring can be carried out using, it is recommended to start processing in March, when the air temperature is plus 5 and above.

Every summer resident wants a cozy and beautiful garden all year round, for this the trees need to be healthy. Fruit and berry trees should be sprayed against pests and their larvae in early spring. To begin with, the trees are pruned, inspected, and old bark and lichens are removed.

It is necessary to spray before the buds begin to awaken, because the purpose of this event is to destroy pests that are in the wintering stage: copperhead, aphid eggs, apple blossom beetle, etc. Early spring spraying of the garden using the double action method allows you to achieve maximum effect.

For this, the following proportion is used: urea (urea) with 3 percent copper sulfate in the proportion of 10 liters of water, stir 700 grams of urea and 50-100 grams of copper sulfate. This solution will get rid of overwintered garden pests and provide sufficient nutrition for bushes and trees in the form of nitrogen fertilizer. Sprayed trees will have a great start in spring.

2.3 Autumn treatment of the garden with copper sulfate and urea

Every garden, even the most well-groomed one, is not immune from diseases and pests. This is especially true for apple trees affected by scab. Insects and wind carry disease-causing spores, and damp weather promotes infection.

Scab damages leaves and shoots and spoils the harvest.

Destroying pathogenic spores in the fall will help prevent scab next season.

The tree is sprayed with a solution, which has the original name - Bordeaux mixture. It is used by gardeners to combat a large number of infections. You need to spray apple trees with a solution prepared from 400 grams and 300 grams of lime diluted in 20 liters of water. Autumn treatment of apple trees will save trees and crops from diseases and pests.

Also in the fall, currants and grapes are treated with urea. Currants are treated with urea in the fall to kill pests and prevent rotting of the root system. With the onset of cold weather, humidity increases, which is the optimal environment for the emergence of diseases and widespread infections. To do this, autumn treatment of the garden with urea is carried out in the form of spraying.

Processing grapes in the fall is an effective way to control pests. Spraying with urea will rid the grapes of leaf roller and phylloxera. Any one can be added to the solution to enhance the effect.

Treating the garden with urea will help gardeners protect their plants and fruit trees from pests, and the roots from rotting. To achieve the best results, it is necessary to use the drug in the correct proportions and for a certain period of time. The processed harvest will be abundant and rich. Carbonite is a universal fertilizer; it will help garden and vegetable plants grow.

Urea is a fertilizer that many gardeners use when growing various types of vegetables. It is worth noting that it also has another name – urea. Proper fertilizing with urea helps improve fruiting of plants and stimulates their development. However, before using such fertilizer, you need to familiarize yourself with what urea is and how to use this fertilizer in the garden.

Urea, or urea, is a chemical compound with carbonic acid. Externally, humatized urea is similar to ordinary transparent crystals that are odorless. They dissolve easily in ethanol, ammonia and warm water. Urea grade B contains quite a lot of nitrogen and may have a white or yellowish tint.

Currently, urea fertilizer is used in various fields of activity. For example, in the medical industry, urea is used to create drugs that can remove water from the human body and relieve severe swelling. The substance is also often added to various sleeping pills.

Sometimes urea is used as a food additive to improve the aroma and taste of products. Quite often it is added to chewing gum and baked goods.

However, urea is most often used as a fertilizer. The use of urea in agriculture allows you to increase the amount of nitrogen in the soil. Thanks to this, soil fertility improves and the yield of grown vegetables increases. This nitrogen fertilizer is highly active and is therefore quickly absorbed by plants. It is recommended to use it for feeding vegetable crops during pre-sowing preparation of the site or when the bushes begin to gain green mass. In summer, during fruit formation, you should not use urea, as this can significantly worsen the yield.

Advantages and disadvantages

Granular urea, like any other plant nutrition product, has its advantages and disadvantages. The advantages of urea as a fertilizer include:

• increasing the rate of green mass formation;
• an increase in the amount of protein in almost all cereal crops that were fertilized with urea;
• improving the plant immune system and preventing pests;
• absence of large amounts of nitrates even after frequent use of fertilizing.

There are not many disadvantages to using urea, but you should still be aware of them before using the fertilizer. The disadvantages include:

• if dosages are not observed, serious burns may appear on the seedlings, which in the future will lead to the death of the bushes;
• the temperature of the solution is much lower than the air temperature, so it should only be used on warm days;
• Urea is not recommended to be combined with other fertilizers.

How to dilute urea

A liquid urea solution can be used to feed almost any garden or vegetable crop. Before using urea, you need to familiarize yourself with its varieties. There are two main markings:

1. Marking "A". This brand is produced to create special feed additives for animals. Sometimes a fertilizer with this name can be granulated to create a resin or glue.
2. Marking "B". This urea fertilizer is granulated for feeding plants grown in the garden.

For dilution of fertilizing fertilizer, it is the “B” brand that is used, since the “A” label can negatively affect the quality of the resulting crop. To create high-quality fertilizing, you should familiarize yourself with the peculiarities of preparing the solution. It is recommended to maintain the correct proportions of urea, which depend on the plants being fed. For example, foliar feeding of potatoes with urea is carried out using a solution prepared from 50 grams of fertilizer and 10 liters of water.

To properly feed potatoes, 3–4 liters of the prepared mixture are used for each bush.

The optimal dosage of urea when creating a fertilizing mixture for fertilizing shrubs and trees is 30 grams per 10 liters of water. The preparation of such a mixture is carried out in several successive stages. First, all the granules are poured with two liters of cold water and stirred until they are completely dissolved. Having diluted the granules, you need to add another 8 liters of liquid to the mixture.

How to apply fertilizer

Having familiarized yourself with the features of preparing the working solution, you should figure out how to carry out foliar fertilizing with urea. Instructions for using this fertilizing mixture will help improve vegetable yields in the future.

Top dressing

Quite often, potatoes are fertilized with urea. It is recommended to do this while planting the plant. However, some people use this method when growing bushes. To do this, urea granules are dug in near the potato bushes to a depth of about ten centimeters. In this case, the correct dosage must be observed. When adding granules to the soil, you must remember that 200-gram glasses can hold 130 grams of the substance, a matchbox can hold 15 grams, and a tablespoon can hold only 10 grams.

If manure or any other organic fertilizer with a large amount of nitrogen was added to the soil before adding urea, the dosage will have to be reduced by half.

Granules need moisture, so almost immediately after adding them to the soil, abundant watering is carried out. You need to pour at least a liter of water under each bush.

In dry form, granules are often used when preparing soil for planting vegetables. It is customary to do such preparatory work in the fall when digging up the site. In this case, about 150 grams of urea will have to be consumed per square meter of garden.

Watering

Urea with the addition of humates is an organic fertilizer that can be used for watering grown vegetable crops. There are various folk recipes for preparing liquid for watering plants. To treat shrubs and low trees, use a very concentrated solution. Therefore, to prepare the working mixture, you will have to add at least 350 grams of the substance to 10 liters of water.

Currants and other berries do not need such a concentrated liquid. In this case, to prepare the mixture, only 40 grams of urea are added to a ten-liter container of water. Vegetable crops need nitrogen fertilizers, so more concentrated mixtures are used for watering them. To create them, you will have to mix 10 liters of water and 200 grams of urea.

However, when using a fertilizer such as urea in the garden, you must remember that it oxidizes the soil. Before using it, it is recommended to normalize the acidity of the soil and add about 400 grams of chalk to it.

Spraying

Many people are interested in whether it is possible to use urea to spray vegetables. You can spray seedlings with this solution, and there is nothing wrong with that. Spraying of potatoes and other vegetable crops is carried out in the evening or in the morning when there is no sun.

To prepare a urea solution, it is recommended to add 30–50 grams of fertilizer to five liters of cold water. If no plant has ever been sprayed with mineral solutions, you can make the mixture more concentrated. To do this, add 120 grams of urea to a ten-liter saucepan. About two liters of liquid should be consumed per plant.

The prepared mixture can be used not only to stimulate the development of seedlings, but also to protect them. The prepared spray liquid can destroy all pests on the bushes and protect plants from the most common diseases. It is best to use this solution against copperhead, weevils and flower beetles.

Before spraying, you must make sure that there will be no heavy rains in the coming days. If there is a downpour in the first two days after spraying, you will have to treat the seedlings again, as the urea will be washed off the leaves.

How to replace urea

Many people are interested in whether it is possible to replace one fertilizer with another. Since urea contains a large amount of nitrogen, any other nitrogen mixture can be used instead. Sometimes, in the absence of urea, vegetables are fed with calcium, ammonium or potassium nitrate. You can also use diammophos or ammophos.

Conclusion

Urea, or urea, is the most famous nitrogen fertilizer. It can be used everywhere: at home, in the garden, in the greenhouse and in the vegetable garden. Urea is highly effective, low cost, and can be purchased at any garden store.

Urea can be used to feed any crops: ornamental, fruit, and vegetable. The fertilizer contains ammonia nitrogen, which, rather than inorganic nitrogen salts, is absorbed in plant tissues, is intensively used in biochemical processes, and therefore its use is more effective than other nitrogen fertilizers. Among other beneficial properties, urea serves as an excellent preventive agent for the autumn treatment of apple trees against scab.

How to properly apply urea to feed plants

When adding urea granules to the soil, they must be immediately embedded in the soil to a depth of 3-4 cm. In soils with high biological activity, urea turns into ammonium carbonate in 2-3 days, and this compound easily decomposes in air to gaseous ammonia, that is, part the nitrogen simply evaporates. Therefore, surface application of urea without incorporation into the soil is ineffective.

Is it necessary to apply urea when planting vegetables and berries?

Before planting, the granules are dug up along with the soil at the rate of 5-10 g/m². However, ammonia gas, when released, can damage young shoots. Therefore, it is better to add urea to crops in advance, 1-2 weeks before sowing. The negative effect of ammonia on young shoots can be almost completely neutralized by using potassium fertilizers. At the same time, the efficiency of fertilizers will increase.

Features of feeding perennial flowers with urea

To feed perennial flowers during the growth period, use 20-30 g of urea per 10 liters of water. Watering is carried out at the rate of 1 liter per adult plant.

Features of feeding trees and shrubs with urea

Fruit, berry and ornamental trees and shrubs are fed once or twice a season. Urea is applied over the entire crown projection, scattered over the surface before watering. When using organic fertilizers, the dose of urea is reduced by a third or even half. On average, from 150 to 250 g are applied to an adult fruit-bearing apple or pear tree, 100-140 g to a plum tree, and 30-40 g to a currant tree.

Fertilizing vegetable crops with urea: when used dry - 5-20 g per 1 m².

For cucumbers and peas add no more than 5-8 g/m² of dry urea,

For zucchini and squash add - 10-15 g/m² urea,

Under tomatoes and peppers- up to 20 g/m² urea.

For watering vegetable crops, you can prepare a solution: 20 g of urea per 10 liters of water. Water at the rate of 1 liter of the prepared solution per plant.

Foliar fertilizing with urea: why is it needed and how to do it correctly?

When there are signs of nitrogen starvation in plants, as well as in case of shedding of ovaries, it is useful to carry out foliar fertilizing with urea. Urea has an advantage over nitrate and other nitrogen fertilizers: it burns plant leaves less. The consumption of urea solution for foliar feeding is approximately 3 liters of working solution per 100 m².

The crowns of fruit trees are sprayed at a concentration of no more than 0.5% (50 g of urea per 10 liters of water). It is desirable that the urea solution in a fine-droplet state falls on both the upper and lower sides of the sheet, wetting it evenly.

For indoor plants, a urea solution for foliar feeding is prepared at the rate of 5-8 g of urea per 1 liter of water. If the plants have very pale leaves (which indicates a nitrogen deficiency), then 3 g of magnesium sulfate (magnesium sulfate) should be added to 1 liter of solution. The use of magnesium sulfate will reduce the risk of burns and increase the effectiveness of feeding, since magnesium is part of chlorophyll.

Foliar feeding is carried out in the morning or evening.

Urea - as a means of protecting plants from diseases

Urea can also be used to control pests and diseases.

When the first warm spring days arrive (average daily air temperature is +5 °C and above) before the buds begin to swell, a concentrated urea solution (500-700 g of urea and 50 g of copper sulfate per 10 liters of water) is used to spray fruit trees against pests, as well as from scab and other diseases.

Early spring spraying helps delay flowering and reduces the likelihood of damage to flowers by spring frosts in heat-loving crops (cherry plum, apricot and others).

In autumn, at the end of leaf fall (late October - early November), to protect apple trees from scab and other infectious diseases, spray the trees with a solution (500 g of urea per 10 liters of water). In principle, preventive treatment of trees with a urea solution can continue on all days when the air temperature is +5 °C or higher. It is also useful to treat fallen leaves. On young trees, before treatment, carry out a test spraying in advance and make sure that the concentration of the urea solution does not harm the bark or leave burns on it. For trees older than 6-10 years, carefully clean the places where the old bark has peeled off, heal cracks and fill up hollows.

5 Basic rules for using carbamide (urea) in the garden

1. In open air, ammonia evaporates. To avoid its loss, fertilizer should be embedded in the soil to a depth of at least 3-4 cm.
2. There must be a layer of soil between the urea granules and the freshly sown seeds. It is better to use urea together with potassium fertilizer.
3. Urea can be mixed with other fertilizers only if they are dry, and only before sifting, as it increases the hygroscopicity of the mixture. You cannot mix urea with simple superphosphate, lime, dolomite and chalk.
4. A urea solution during foliar feeding does not burn the leaves (5-10 g per 1 liter of water), unlike ammonium nitrate. Already 48 hours after spraying with urea, nitrogen is found in plant protein.
5. Store unused fertilizer granules in a dry place, since urea absorbs moisture well.

INFORMATION ABOUT THE DRUG

Urea, or urea,- a chemical compound that is carbonic acid amide CO(NO2)2. This is an organic compound, but it is usually classified as a mineral nitrogen fertilizer.

Appearance of carbamide (urea). They are colorless, odorless crystals. The finished product looks like round granules of white, grayish or slightly yellow color.

Composition of carbamide (urea). This is the most concentrated of nitrogen fertilizers: pure urea contains about 46.2% nitrogen!

Properties of carbamide (urea). It is highly soluble in water; solubility increases with increasing temperature. In an aqueous solution, urea hydrolyzes to form ammonia and carbon dioxide, which determines its use as a mineral fertilizer.

Use of carbamide or urea. Used for root and foliar feeding, as well as to combat pests and diseases.

Nitrogen fertilizers are needed to feed garden and ornamental crops. With their help, plants begin to grow intensively and acquire large, richly colored leaves. This article is all about the use of urea, which improves the growth of green spaces in the city and rural greenhouses. You can practically get acquainted with the correct feeding of plants with urea by watching the video.

The first of the synthesized protein compounds is urea. This scientific name is urea - a fertilizer for feeding garden and ornamental crops, which is used to accelerate growth. Urea belongs to the group of nitrogen fertilizers and has been used in agriculture since the 18th century.

The product is produced by synthesis from inorganic substances and is a granular mass consisting of round, milky, sometimes translucent granules. Currently, the industrial production of urea is in the form of tablets.

Urea can be purchased in granule form

In terms of its chemical composition, almost half of urea consists of pure urea, which dissolves without residue in any liquid, including water.

When applied to the soil, granulated 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 growing the crop. 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 nutrition of plants with the substances necessary for growth.

Nitrogen starvation manifests itself in plants in slower growth, yellowing of leaves, inhibition of plant development and complete death. The application of urea is indicated during the formation of unnaturally thin and short branches with small discolored leaves in fruit trees and berry bushes. A lack of nitrogen is expressed at the beginning of leaf fall in the summer, when most of the leaves on plants turn yellow earlier than expected in nature. In spring, weak, underdeveloped buds form on plants lacking nitrogen.

It is allowed to feed fruit trees and shrubs with urea; it is an effective fertilizer for wild strawberries, strawberries, and all vegetable crops, including carrots, etc.

Urea - how to apply fertilizer correctly

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

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

Fertilizer application

Fertilizing with urea during sowing events– the best option is to use the composition in combination with potash fertilizers. In this case, it is not allowed for the granules to be mixed with the seeds; it is necessary to provide a layer of soil between the granulated fertilizers and the seed.

Fertilizer application during the period of growth– the most effective method is foliar feeding of plantings. To do this, urea 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 fertilizing with urea is not recommended on days when precipitation occurs.

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

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

Treatment with urea against pests

Spraying with urea is effective in controlling plant pests. Spraying is carried out in the spring, when a constant average daily temperature is +5 C. It is important to carry out the procedure before the buds awaken, then all pests overwintering in the scales and under the bark will be guaranteed to be destroyed.

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

Treatment of the garden with nitrogen can be carried out both in autumn and spring.

In autumn, during 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. The solution is used to treat trees along the crown and leaf litter. This treatment is a very effective remedy for infectious diseases of garden trees; next year the garden 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 urea, plants easily absorb nitrogen, which has a positive effect on their growth and the expansion of green mass.
• Treatment of plants with a solution of fertilizer on the leaves does not cause burns to the leaf blade; this foliar feeding is an effective and gentle means, which, along with fertilizing plants, can effectively fight garden pests, as well as pathogenic infections.
• The urea solution is quickly absorbed by plants sensitive to elevated pH levels in the soil.
• Excellent results were noted when fertilizing plants with urea in irrigated areas, as well as when applied to crops grown when the beds were filled with water.

It is very important to observe the dosage when applying fertilizers.

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

The disadvantages of fertilizing with urea are the following aspects:

• A strong concentration of fertilizer when applied to the soil when sowing seeds can reduce the germination of seeds and delay their germination.
• Urea requires careful storage.
• The use of urea in a mixture with phosphorus fertilizers is possible only when mixing absolutely dry substances; increased acidity from the effects of mixed fertilizing must be neutralized by adding chalk to the soil.

Advice! Granular urea must be stored in a dry place, otherwise the fertilizer strongly absorbs moisture and turns into lumps.

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