DMPP Nitrification Inhibitor

2017-12-28 back

Product Description

DMPP is effective during the first step of nitrification. It reduces the activity of ammonium oxidizing bacteria (represented by Nitrosomonas) in the soil, and then hinders the conversion of NH4-N to NO3-N, so as to avoid the leaching or volatilization of nitrogen. It has no effect on the second step of nitrification, but as long as the first step of nitrification is inhibited, the whole nitrification reaction is inhibited.

Product Features 

Long-acting for nitrogen release control: the peak of releasing ammonia N is postponed by 15 days, the peak of releasing nitrate N is delayed by about 25 days, and the fertilizer effective period is extended to 110-120 days. All these features mentioned above allow fertilizers to satisfy the crop needs during the whole season.

High-efficiency in nitrogen release control: the peak of ammonia N releasing value is reduced, which is useful for lowering ammonia pressure and loss of nitrogen caused by ammonia volatilization, improving ammonia concentration and persistence time in soil solution, which in turn reduce the nitrate nitrogen loss.

Nourishment by increasing ammonium: prolong the release cycle of ammonia nitrogen, raise the ratio of ammonia nitrogen (ammonia N: nitrate N>3/7) , which in turn raise the NUE up to 30%. 

 

Directions for use 

Use DMPP liquid spray to the granular surface of urea or ammonium nitrogen fertilizer, under normal circumstances recommended to add 1-3 kg per ton of fertilizer.
