Urea 46% N, Diammonium Phosphate (DAP), Complex NPK (Nitrogen, Phosphorus, Potassium) fertilizers

Urea 46% N, Diammonium Phosphate (DAP), Complex NPK (Nitrogen, Phosphorus, Potassium) fertilizers

UREA is a spherical white solid. It is an organic amide molecule containing 46% nitrogen in the form of amine groups. UREA is infinitely soluble in water and is suitable for use as an agricultural and forestry fertilizer as well as for industrial applications which require a high quality nitrogen source. It is not a poison to mammals and birds and is a benign and safe chemical to handle.

Advantages of fertilizer urea

Urea can be applied to soil as a solid or solution or to certain crops as a follar spray. Urea usage involves little or no fire or explosion hazard.urea's high analysis , 46 % N, helps reduce handling , storage and transportation costs over other dry N forms. Urea manufacture releases few pollutants to the environment

Potassium chloride fertilizers

Non- chloride K fertilizers:

Potassium sulfate, Potassium and magnesium sulfate and Potassium nitrate.

Controlled release chemical fertilizers

Controlled-release fertilizers release nutrients according to specific environmental conditions of temperature and humidity, and this ensures the provision of nutrients to the plant at various stages of its growth.

Slow release chemical fertilizers:

Slow-release fertilizers rely on gradually releasing nutrients over a long period of time, which is useful in reducing the risk of excessive fertilizer use.
