Fertilizer Muriate Potash K2o Kcl 60% Min CAS 7447-40-7

Urea is a white granular solid fertilizer with a nitrogen content as high as 46%, making it the nitrogen fertilizer with the highest nitrogen content at present. It is highly soluble in water, has strong hygroscopicity and is prone to caking during storage. Urea itself cannot be directly absorbed by plants. It needs to be decomposed by microorganisms in the soil and converted into ammonium nitrogen and nitrate nitrogen before it can be utilized by crops. This transformation process is affected by temperature, humidity and soil pH. Urea is suitable for all types of soil and crops and can be used as base fertilizer or top dressing. However, it is best to bury it in the soil when applying it to avoid exposure on the surface, which may cause nitrogen volatilization and loss. It has a fast fertilizer effect and is inexpensive. It is one of the most commonly used nitrogen fertilizers in agricultural production.
