Slow-release urea CO(NH2)2; 46% N, 0.069% NBPT: In order to prevent urea from quickly turning into ammonium and nitrate, which are nitrogen forms that can be quickly broken down and absorbed by bacteria, and to prevent or reduce nitrogen loss to the air by flight or to the ground by washing, 0.069% partially disabled bacteria with the urease enzyme that breaks down urea. It is urea mixed with NBPT N- (n-butyl) thiophosphoric triamide) inhibitor. Thanks to this compound, bacteria that decompose urea work slower, and less ammonium and nitrate pass into the environment. Therefore, in periods when plants do not take them, nitrogen losses do not occur or are less. It has superiority over normal urea fertilizer in sandy region soils with excessive rainfall and washing.
