APPLICATION
Mostly used as nitrogen fertilizer in agriculture, also used as raw material in production of plastics, resins, coating, and medicine.
it is used as a surface fertilizer, alone or mixed with other fertilizers;
- it is very effective for crops with long growing seasons;
- determination on the field is based on the culture and climatic conditions and soil
- urea may be used on all soils;
- it is applied both early spring and during the vegetation.
Apply in subsoil and cover when for calcareous and alkaline soils.
Better to apply to together with P K or organic fertilizers
