Urea (formula - (NH2)2СО)
Urea composition: N-46.2)

Urea (urea) is a spherical, white, solid substance based on 46 percent nitrogen. Produced in accordance with GOST 2081-2010 in accordance with technical specifications.

The main application of urea is agriculture, where it is used as a feed additive and fertilizer. Over the past decades, urea has surpassed and even almost replaced ammonium nitrate as a fertilizer. This success lies in the amide form of nitrogen, which, when interacting with the soil, is converted into ammonium carbonate. This form of nitrogen allows it to remain in the soil for a longer time, facilitating better absorption of nutrients by the plant.

Regardless of the type of urea, be it granular (prilled) or liquid urea mixture, the end results are relatively identical.

 

*Note:

1. In terms of the degree of impact on the human body, urea is classified as a moderately hazardous substance (hazard class 3 according to GOST 12.1.007)

2. The guaranteed shelf life of urea is 6 months from the date of manufacture,

Shelf life – unlimited, subject to storage requirements

 

Urea. Norms and application of fertilizer

When used correctly, urea can have a beneficial effect on plant growth and yield, and can also help increase protein content.

It must be remembered that by leaving urea on the soil surface for a long time in warm weather, you risk “losing” the nitrogen from the fertilizer, since nitrogen is primarily a gas that can volatilize. Therefore, to avoid such losses, it is recommended to add urea during soil cultivation. Under irrigation conditions, urea interacts without any obstacles. In the case of non-irrigated fields in the northern regions of Kazakhstan, only 6-7 mm of precipitation is sufficient for the penetration of urea into the deep layers of the soil to avoid the loss of ammonia.

Urea can be applied in the pre-sowing spring period and at all stages of the growing season. The consumption of urea is quite economical, for example, an acceptable application rate in the pre-sowing period on average per 1 hectare of grain crops is 50-70 kg (to ensure the minimum requirement of the crop)

The rate of foliar feeding (spraying) with urea during the growing season is 3-7 kg per 1 hectare, which when pouring out the general solution is 100-200 l/ha.
