What is urease inhibitor---NBPT
Urease inhibitor---NBPT is a substance that inhibits hydrolytic action on urea by the enzyme urease.  YMS urease inhibitors---NBPT 
prevent or suppress over a certain period of time the transformation of amide-N in urea to ammonium hydroxide and ammonium through
the hydrolytic action of the enzyme urease. By slowing down the rate at which urea is hydrolyzed in the soil, volatilization losses of ammonia 
to the air (as well as further leaching losses of nitrate) is either reduced or avoided. Thus, the efficiency of urea and of N fertilizers containing 
urea (e.g. urea ammonium nitrate solution), is increased and any adverse environmental impact from their use is decreased
