1. Supply nitrogen nutrition.it is rich in Nitrogen nutrition, medium element, and contain bio-fulvic acid, which satisfy the requirements of crops. Nitrogen can improve crop growth, buds fatness, roots strength, well leaf photosynthesis.

2. Increase the total biomass and economic output, improve the nutritional value of agricultural products, especially increase the protein content in seeds, improve the nutritional value of food.

3. Nitrogen is the main component of protein in crops. nitrogen is also a component of chlorophyll and many enzymes. Chlorophyll is a necessary substance for photosynthesis of crops, and enzymes are catalysts for the transformation of various substances in crops. Nucleoproteins and alkaloids also contain nitrogen.
