Urea contains 46% nitrogen in amide form, is the most concentrated among solid nitrogen fertilizers. Water-soluble, nitrate-free fertilizer with an almost neutral reaction.
It is used in fertilization systems in all soil-climatic zones of Ukraine in the main and extra-root foliar nutrition. In the system of fertilization of spring grain crops, they are applied in pre-sowing cultivation. It is more appropriate to use urea for crops with a long growing season - beets,
corn for grain, etc. In the soil, the amide form is transformed into an ammonia form, and later into a nitrate form. This process occurs slowly, so nitrogen from urea is evenly absorbed by plants during the growing season, and does not excessively accumulate in the plant and in groundwater. Little is washed out of the soil, nitrogen losses in the soil are minimal. The amide form of nitrogen is able to be quickly assimilated through the leaf surface.
The higher the soil temperature, the better and faster nitrogen from urea is assimilated. It has less effect on very acidic or recently limed soils. Less effective also on overmoistened, cold soils and when applied in early spring on winter crops. They are trying to work urea into the soil, because the losses during surface application are 20-30% higher than with nitrates.
