Nitrogen Fertilizer Urea 46 Prilled Granular Urea Fertilizer 46-0-0 Urea N46%
Urea, also known as carbamide, has the chemical formula CH4N2O. It is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal.
Urea is a high-concentration nitrogen fertilizer, a neutral quick-acting fertilizer, and can also be used to produce a variety of
compound fertilizers. Urea is suitable for base fertilizer and top dressing, and sometimes as seed fertilizer.
As a neutral fertilizer, urea is suitable for various soils and plants. It is easy to store, easy to use, and has little damage to
