The Carbon Cycle and Soil Organic Carbon

erosion and nutrient leaching Soil organic carbon is also important to chemical composition and biological productivity including fertility and nutrient holding capacity of a field As carbon stores in the soil increase carbon is sequestered and the risk of loss of other nutrients through erosion and leaching is reduced.
