As an important urease inhibitor, NBPT is one of the most successful additives utilized to increase the efficiency of urea-based fertilization, prevent the loss of ammonia nitrogen. Inhibit the activity of urease and slow down the conversion from urea to NH4+, hold N by urea form in a long term. It will decrease the concentration of NH4+ in soil solution, reduce potential volatilization loss and prevent harm to seedlings.
