Topics to be covered include a discussion of what soil carbon sequestration is, how and where in the soil it occurs, and its role in maintaining important soil properties. The author draws upon his experience and that of others about practices for various parts of the US to describe on-farm and experimental agricultural systems and their degree of success to sequester carbon and improve soil quality. Included is an overview of carbon sequestration strategies and possible regional methods to compare soil C sequestration for different land uses. The discussion will include information about cropland, pasture, and rangeland as well as information about developing national issues and USDA programs and opportunities to encourage land managers to sequester soil carbon.
