Soil organic matter is stabilized by organo-mineral associations through two key processes: The role of the carbon to nitrogen ratio
The loss of organic matter (OM) from soil during long-term agricultural cropping results in a
decrease in the inherent fertility of the soil as well as releasing greenhouse gases. Despite …
