- Abstract
The article features a study on the long-term cropping system effects on carbon sequestration in Eastern Oregon. Cropping systems that maintain or improve levels of soil organic carbon (SOC) may lead to sustainable crop production. SOC has beneficial effects on soil quality and productivity. Soil samples were taken at different measurements of soil depth profiles from grass pasture, conventional tillage winter wheat-fallow, and fertilized and unfertilized plots of continuous winter wheat, spring wheat, and spring barley. The results show that tillage and cropping intensity influenced carbon sequestration. There was more potential to sequester carbon with less tillage and more intensive cropping than with more tillage and less intensive cropping.
