Nitrification Inhibitor硝化抑制剂

Key points

• It acts on soil nitrifying bacteria, slowing the conversion of ammonium to nitrate and thereby reducing leaching and denitrification losses.
• It is commonly used in fertilizers containing ammonium nitrogen, such as urea, urea-ammonium nitrogen fertilizers and ammonium-bearing compounds.
• Effectiveness is strongly temperature-dependent: nitrification is already slow at low temperatures, so the marginal benefit of the inhibitor falls accordingly.
• It is a synergistic material, and adding it does not change whether the product requires registration or filing under China's fertilizer registration rules.
