Urea - nitrogen fertilizer for soil


Every summer resident, who grows vegetables and fruit and berry plants in his personal plot, knows a lot about fertilizers, which should be used to achieve the highest yields. Among the group of fertilizers for self-preparation and industrial production, special attention is paid to nitrogen fertilizers. It is nitrogen that is often lacking for many plants for full vegetative development and effective fruiting.

Urea is one of the most popular nitrogen fertilizers. This is the so-called popular urea, containing in its composition fifty percent nitrogen. The chemical formula of urea is as follows.

Therefore, it is considered the most concentrated fertilizer available in the chemical industry's arsenal.

Urea is often produced in granular form. Packing of the obtained granules in many cases varies, since the applied doses are always calculated from the soil areas. If nitrogen fertilizer is applicable at the dacha, then one or three kilograms can be purchased.

If, however, whole field lands are treated, it is advisable to purchase urea in plastic bags.

Fertilizer urea is the hardest substance in structure that is not able to absorb excess moisture from the environment, due to which it has a long shelf life, excellent bulk properties, due to which it is very well dispersed during use in practice.

The main advantages of the use of urea:

  • nitrogen fertilizer has the property of regulating the growth of the vegetative mass of any plant species;
  • introduction when growing crops, urea increases the protein and gluten content in the resulting grain yield;
  • high yields of all crops depends on the sufficient nitrogen content in the soil on which they are grown.

Useful urea

If you wish to fertilize the soil with any fertilizer, you should always know the rate of application, in order not to harm, but rather create the most favorable conditions for the development and growth of the planted or planted plants.

Urea as a fertilizer can be used in a granular state or in a dissolved liquid form.

The application rate of urea for different crops is different, below are the application rates before sowing:


  • rapeseed, barley, wheat, rye - two kilograms per hundred of the future sown area;
  • potato, fodder and sugar beet - two kilograms per hundred;
  • onions, tomatoes, carrots and cabbage - twenty to thirty grams per square meter of sown area.

For the purpose of feeding and feeding already planted crops, the following standards apply:

  • for rye, rapeseed, wheat and barley, one and a half kilograms of carbamide is weaved;
  • for fodder and sugar beet, as well as potatoes - one and a half kilograms per hundred;
  • for corn, garden fruit trees and shrubs - ten grams per square meter.

To feed the rose bushes and vegetable seedlings, a special solution is prepared containing the following proportions: 90 grams of urea is dissolved in 10 liters of cold water.

The main point in fertilizing the soil is not to overdo it with the amount of nitrogen, since an overabundance can negatively affect the seedlings and the seedlings that have already been taken.

You should know that urea nitrogen fertilizer should be embedded in the soil, because the instantaneous chemical reactions of urea elements with soil bacteria, urea in a short period of time turns into ammonium, which evaporates too quickly, and this in turn causes the loss of nitrogen, which is so necessarysoil in order to supply plants with nutrients.

If the feeding is carried out by the method of dispersing the granules manually or by the mechanized method, then after the obligatory attribute abundant watering of the fertilized agricultural plantations should be carried out.

Urea is often mistaken for saltpeter. However, it is different in structure fertilizer. Saltpeter is less resistant to wet conditions, while carbamide perfectly fulfills its purpose in various soil areas - arid and too moist.

In the first days of application, urea manifests itself as a weakly alkaline fertilizer, which is very useful for acidic and slightly acidic soil.

The nitrogenous fertilizer introduced into the soil can be completely absorbed by growing plants, and it can also remain in some percentage ratio in the soil, but while in it, urea does not change its chemical composition and has a beneficial effect on the subsequent sowing of plants.

Urea is very loyal to the effects on foliage and shoots; it is not capable of burning plants like saltpeter, therefore, it is applicable both for external processing of crops and for root feeding.
