The invention provides a low-cost and environment-friendly nitrogen fertilizer loss control method and fertilizer loss control. Attapulgite is a natural one-dimensional nano-mineral material. Attapulgite is compounded with organic flocculant polyacrylamide and inorganic flocculant polyaluminium ferric chloride to fix nitrogen (ammonia nitrogen, urea, etc.). ) and reduce nitrogen loss through leaching, runoff and volatilization. The invention can reduce the loss of nitrogen by 20%-60%, improve the utilization rate of nitrogen fertilizer, reduce the pollution of nitrogen to water and atmosphere, and improve soil after long-term application.
