Effects of Conventional Tillage and Conservation Tillage on Soil Organic Carbon

Abstract:

For the last decades, because of increasing attention to global change, the carbon cycle in the terrestrial ecosystem has become a hotspot problem for every country. It has 1.6 Pg/a C to release into atmosphere because of the irrational land-use, quickening the step of global warming trend. But agricultural soil has the double-sword effects. If improper soil tillage practices are adopted, agricultural soil may become the source of carbon dioxide in the atmosphere. And if adopting effective management measurement and scientific tillage technology, agricultural soil may become carbon sink. This paper reviewed the effects of conventional tillage and conservation tillage on soil organic carbon (SOC), and found that conservation tillage has a huge potential for sequestrating organic carbon compared with conventional tillage. Finally, the important significance of agriculture soil carbon sequestration was discussed in detail.
