Urea is a kind of white granular product which serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is high soluble in water and promote plants to absorb nutrient during sprouting and increasing the utilization efficiency of nitrogen and phosphorus nutrients. Urea is widely used in agricultural and industrial field. 

 Urea is a high concentration of nitrogen fertilizer, is a neutral organic fertilizer, also can be used in the production of a variety of compound fertilizer.No residues in the soil any harmful material, long-term application of no bad influence.Animal husbandry can be used as the ruminant feed.But in the granulation temperature too high will produce a small amount of biuret, also called biuret, has inhibitory effect on crops.Our country regulation with urea fertilizer biuret content should be less than 0.5%.Biuret content exceeds 1%, cannot do seed manure, seedling weight and foliar fertilizer, the issue of the urea content in other also shoulds not be too much or too concentrated.Urea is organic nitrogen, after the soil urease, after hydrolysis of ammonium carbonate and ammonium bicarbonate, use can be absorbed by crops.Therefore, urea in crop 4 ~ 8 days before the period of fertilizer application.Urea is suitable for the basic fertilizer and fertilizer, and sometimes used as a seed manure.Urea before conversion is molecular state, can not be soil adsorption, should prevent the water loss;Into the formation of ammonia and volatile, so also want to deep applied urea turns the soil.Urea all applies to all crops and soil, can be used as a basic fertilizer and fertilizer, dry paddy field all can use.Due to the transformation of urea in the soil can accumulate large amounts of ammonium ion, would result in higher PH 2-3 units, plus urea itself contains a certain number of biuret, its concentration to 500 PPM, will inhibitory effect on crop radicle and plumule, therefore the urea used as seed manure.Urea (nitrogen) can promote cell division and growth, make the branches and leaves grow lush.
