The use of urea fertilizer in the garden in spring, as well as at other times of the year, will definitely help increase yields.

And it is suitable for almost all plants in our garden and vegetable garden.

What is urea, composition, production

Urea has another name - carbamide, a chemical that is carbonic acid diamide. This compound is odorless and colorless crystals that dissolve quickly in various liquids, for example, alcohol, ammonia and ordinary water.

In its pure form, carbamide consists of 45-50 percent nitrogen; it is used in various fields. For example, in the medical industry, it is the basis for the production of dehydration solutions that promote the elimination of fluid from the body. In addition, urea is used in the manufacture of sleeping pills, in the food industry to enhance the taste, in the production of bread, rolls and even chewing gum.

Most often, urea is used in the agricultural industry, urea is a fertilizer that saturates the land with nitrogenous substances that increase the rate of fruiting and accelerate the growth of agricultural crops.

If this fertilizer is applied for wheat or for other grain plants, then the amount of protein in them increases significantly. All plants quickly absorb urea, as this substance has a high rate of activity.

Application of urea fertilizer in the garden in spring

Before applying this fertilizer in the spring, it will be helpful to make sure that the soil is lacking nitrogen and not any other elements.

Here are the main signs that show that plants lack nitrogenous compounds:

  • the process of growth and development slows down;
  • the leaves become small and narrow, their shade fades;
  • foliage falls off much earlier;
  • bushes branching worse than usual, shoots become lethargic and thinner;
  • kidney formation gets worse.

Urea is introduced into the soil in the spring, as a separate fertilizer, or combined with any other top dressing. The amount of fertilizer applied directly depends on the condition of the soil and those plants that will be planted.

Urea is applied immediately before sowing seeds or before planting crops. Top dressing is applied one to two weeks before planting.

In the course of planting seedlings or seed, urea granules can be introduced. However, in this case, the roots of plants or seeds should not be allowed to come into direct contact with the fertilizer, otherwise the plants will develop slowly.

In order to prevent this, it is important to first add top dressing to the hole, then fill it with a small layer of soil, and then sow. In the spring, you can combine the application of urea with fertilizers containing potassium.

Let's watch a useful video on the use of urea fertilizer in the garden in spring:

Do I need to apply when planting trees, shrubs, vegetable crops

Urea is used as a top dressing for vegetables, various shrubs and fruit trees; a different dosage is applied for each crop:

  • when planting potatoes, tomatoes, beets and other similar crops, about 10-20 grams of the substance is applied per square meter;
  • for legumes or for cucumbers, use from 5 to 10 grams of dressing per square meter;
  • to get a good harvest of eggplants, zucchini, add urea twice. The first time, fertilizer is applied when planting a crop, and the second time is at the beginning of the formation of ovaries. On average, 10 grams of the substance are used for each square meter of earth;
  • so that trees or shrubs give a good harvest of berries or fruits, it is recommended to use urea. Each fruit and berry crop has its own dosage. To feed cherries and plums, 120 grams of carbamide is diluted in 20 liters of water. To fertilize apple trees, 200 grams of the substance are diluted in 10 liters of water. The diluted fertilizer is applied into the grooves that are made around the trunk along the perimeter of the crown;
  • gooseberry or currant bushes are fed, while the buds have not yet swollen, urea is diluted in an amount of 10-20 grams per 10 liters of water.

Root and foliar feeding, urea application rates

Foliar fertilization is carried out when green crops are already actively growing. The fertilizer is diluted in water and all parts of the culture that are above the ground are irrigated with a solution, irrigation is carried out in the morning or evening, in calm, dry weather. Also, this procedure is performed with shedding of ovaries or nitrogen starvation.

Root feeding is the introduction of granules of a substance into the soil either before planting or after planting crops. It is important to mix the fertilizer with the soil, after adding urea, the earth is watered with plain water. The urea application rate depends on the crop being fertilized.

Effectiveness of application in combination with other fertilizers

Urea can be used alone or in combination with other dressings. However, during the combination, the growing season and soil composition should be taken into account. For example, if the composition of the earth is acidic, it is recommended to add lime to the soil, it neutralizes the acid.

It is important to apply any additives only dry and immediately after mixing with urea.

Basically, urea is combined with organic substances or superphosphate. Here is a list of fertilizers that can be combined with urea:

  • potassium sulfate;
  • cow dung;
  • sodium nitrate;
  • potassium chloride.

But there are limitations, it cannot be used simultaneously with gypsum, wood ash, dolomite flour, calcium nitrate and chalk.

Application in the garden, how to breed urea for spraying trees in spring, dosage

Urea treatment in spring is carried out three times:

  • The first manipulation is carried out at the first warming, the temperature outside should not be less than five degrees. In this case, the optimal dosage is 700 grams of urea for ten liters of water.
  • The second procedure is performed during the flowering period of the culture. It is very important to add a small concentration of the substance so as not to burn the buds, buds and leaves. Dosage: for ten liters - 50 grams of fertilizer.

The last spring feeding is carried out during the ovary period. Dosage: 600 grams of urea for ten liters of water.

Do not reduce or increase the dosage, the culture will only suffer from amateur performance.

How to properly use urea in the garden and in the garden, we will find out when watching the video:

Urea as a fertilizer for flowers

It is worth considering some of the nuances. For annual plants, fertilizer is applied 2 times per season. The first time - two weeks after planting the seedlings, and the second time at the time of the formation of inflorescences.

Perennial flowers are fertilized three times per season. First, urea granules are added to the soil when planting a crop. Then it is administered during the period of kidney formation. The last procedure is after dropping the buds to nourish the soil and flower for the next year.

Expert advice:

  • two hours before the introduction of urea, water the flowers;
  • for young plants, the concentration should be halved;
  • sick or only planted plants cannot be fertilized;
  • do not apply the procedure on hot days.

Use of urea as a plant protection product

This substance is a good prophylaxis against insects, especially aphids, weevils and copperheads. For this purpose, the solution is prepared in the following proportion: for ten liters of water, five hundred to seven hundred grams of urea. Spraying is carried out.

To cope with diseases: scab or purple spot, a solution is prepared in this way - six hundred grams of carbamide for ten liters of water. The spraying procedure is carried out in the spring, before the formation of buds.

Pros and cons of making urea


  • The substance is well and quickly absorbed, the result is visible after 24 hours.
  • Fertilizer is used in greenhouses, vegetable gardens and for indoor crops.
  • Urea can be used in an apartment, under a film and in an open area.
  • Increases productivity, accelerates growth.
  • Good prevention of harmful insects and plant diseases.


  • It works badly in barren, poor land.
  • Strict adherence to dosage.
  • When in contact with seeds, growth slows down.

As you can see, urea allows you to grow healthy plants on the land and get a large harvest.

The main thing is to follow the instructions, adhere to the proportion and time of feeding.
