Research progress on the influence of irrigation methods on ammonia volatilization in farmland

Ammonia volatilization is an important way to lose nitrogen fertilizer in Agricultural Ecosystems, and the main source of ammonia volatilization in the world comes from ammonia volatilization in agriculture Ammonia volatilization not only reduces the utilization rate of nitrogen fertilizer in farmland, leading to the waste of resources, but also leads to environmental problems such as air quality decline, soil acidification and water eutrophication. The paper reviews the characteristics of furrow irrigation, drip irrigation and sprinkler irrigation and the research results of soil ammonia volatilization under several irrigation methods. It provides a theoretical basis for selecting suitable irrigation management measures to reduce the emission of ammonia volatilization in farmland system.
