Science & mode of action
How KPA reduces ammonia volatilization.
Mode of action: urease inhibition
Potassium polyaspartate (KPA), an organic, biodegradable amino acid salt, acts as a urease inhibitor. It reduces the volatilization of ammoniacal nitrogen from urea-containing fertilizers, which is particularly relevant in alkaline soils or warm, dry conditions.
