- Abstract
Against the backdrop of excessive global nitrogen fertilizer use, the loss of nitrogen fertilizer has led to environmental pollution and resource waste. Therefore, finding effective mitigation measures is of great significance for sustainable agricultural development. This study examined the problems of nitrogen fertilizer loss in soil and the potentials of nitrification inhibitors and urease inhibitors to reduce it by using quantitative analysis methods. Different soil types and treatment areas at the ecological agriculture experimental station were included in the study with different ratios of nitrification inhibitor, 3,4-Dimethylpyrazole phosphate (DMPP), and urease inhibitor, N- (n-butyl) thiophosphoric triamide (NBPT) treatments. The indicators for the degree of nitrogen fertilizer loss measurement included ammonia volatilization, nitrogen leaching, and nitrogen fertilizer utilization efficiency. The results showed that, by using the CO (NH2)2+DMPP+NBPT treatment method, the cumulative losses of ammonia volatilization in sandy soil and clay soil after 15 days were 5,430.36 g N/hm² and 4,130.36 g N/hm², respectively. The nitrogen runoff loss rates were approximately 36-60% and 34-45%, respectively. The nitrogen leaching loss rates were about 20-74% and 15-50%, respectively. The nitrogen fertilizer utilization efficiency for wheat was approximately 36.1-37.4% and 44.3-45.6%, respectively. The results indicated that the utilization of nitrification/urease inhibitors could significantly reduce nitrogen fertilizer loss and improve its overall utilization efficiency. The results of this study offered valuable insights for enhancing environmental conservation and promoting food security.
