Thiourea (ASU) is an important nitrification inhibitor that effectively prevents the oxidation of ammonium nitrogen to nitrate nitrogen by inhibiting the activity of Nitrosomonas sp. and Nitrobacter sp. in soil, thus reducing nitrogen loss.

Thiourea (ASU) is an important nitrification inhibitor that effectively prevents the oxidation of ammonium nitrogen to nitrate nitrogen by inhibiting the activity of Nitrosomonas sp. and Nitrobacter sp. in the soil, thus reducing nitrogen loss. Nitrate nitrogen is easily lost through leaching, leading to nitrogen loss, not only reducing nitrogen fertilizer utilization efficiency but also potentially migrating to water bodies through leaching, causing environmental pollution. Using nitrification inhibitors such as thiourea can reduce the production of nitrate nitrogen at the source, improve nitrogen fertilizer utilization efficiency, effectively increase crop yields, and reduce the negative environmental effects of nitrogen. Therefore, thiourea, as a nitrogen fertilizer enhancer, shows good yield-increasing effects in agricultural production, not only helping to increase crop yields but also reducing the environmental pressure of nitrogen fertilizer use to a certain extent, providing support for sustainable agriculture.
