Ammonia (NH₃) volatilization can result in a substantial amount of surface applied nitrogen (N) being lost into the atmosphere, making it an environmental pollutant as well as reducing plant-available N. However, N can also be easily lost from the soil through leaching,
and nitrous oxide (NO₂). Enhanced efficiency N fertilizers...

Soil organic matter (SOM) is the result of the balance between decomposition and incorporation of detritus from both above and below ground sources into the soil. It composes only a fraction of the soil by mass but it is one of the most critical components. The Detritus Input and Removal...
