In order to improve the utilization rate of nitrogen fertilizer, one way is the use of "Nitrogen synergist" , also is the use of nitrification inhibitor.
Nitrification inhibitor: a general term for active substances that can inhibit soil nitrifying bacteria and microorganisms. It has function of inhibiting the nitrification of ammonium nitrogen by nitrite bacteria in soil to reduce the loss of ammonium nitrogen to nitrate nitrogen. It is suitable for application with various ammonium nitrogen fertilizers or urea.
Urea belongs to amide nitrogen and needs to be converted into ammonium nitrogen before it can be absorbed and utilized by crops. Ammonium nitrogen (nh3-n), which is converted into urea after hydrolysis, can exist in the soil for a long time and it can continue to be converted into nitrate nitrogen (no3-n), which is easy to be lost and volatilized. Therefore, nitrification inhibitors can be added to reduce the loss of nitrogen fertilizer and improve the utilization rate.(In other words, nitrification inhibitors are equivalent to black scissors, which can inhibit the activity of nitrifying bacteria and slow the rate of conversion from ammonium nitrogen to nitrate nitrogen.)
Summary - nitrification inhibitor effect:
1.Reduce the loss of nitrogen fertilizer, improve the utilization rate of nitrogen fertilizer, reduce the amount of fertilizer and increase the yield;
2.Reduce the content of nitrite in crops and improve the quality of crops;
3.Reduce the pollution of soil, groundwater and environmental caused by excessive fertilizer application;
4. Ensure that the plant will not lose fertilizer or prematurely age at the later growth stage. More nitrogen can be absorbed during grain development, which is beneficial to protein synthesis and protein content(Nitrification inhibitors can inhibit nitrification, so that nitrogen fertilizer can remain in the soil for a longer time in the form of ammonium nitrogen, which can reduce the volatilization and leaching of nitrogen in the soil.).
