Mitigation of ammonia volatilization and nitrate leaching via loss control urea triggered H-bond forces.

ABSTRACT: Excess nitrogen (N) fertilizer applied to crops, which discharges to the environment, principally through denitrification, runoff, leaching, and volatilization, results in a waste of resources and pollution. Here, a high-performance loss control urea (LCU) was prepared by adding a loss control agent (LCA) with high thermal stability, large specific surface area, and good water retention capacity complex (6%) to traditional urea (94%). The existence of hydrogen bonds between LCA and N source for LCU in the presence of water enhanced N source adsorption capacity, where adsorption between LCA and NH₄⁺-N was strongest, for urea and NO₃^--N was weakest. In a laboratory experiment, cumulative losses of NH₃ volatilization from soils treated wi
