Agricultural soilsCarbon and Nitrogen cycling in agricultural soils drives many soil processes and contributes to ecosystem services provided by soils including nutrient turnover and soil stabilization. Central to many of these processes is the decomposition (mineralization) of organic matter and plant residues. There are several foci for this research, including understanding factors that control decomposition, the fate of residues from genetically modified plants in soils, and the effects of different management on soil carbon stocks.
