Effects of Conservation Tillage on Soil Organic Carbon and Agricultural Productivity
Farmland soil organic carbon pool is the carbon pool affected by human mostly, its recovery has important significance on soil quality enhancement, food security guarantee, water conservation and CO2 emission decrease. Conservation tillage has significant effect on the decrease of water and soil loss, the increase of soil organic carbon and the increase of crop yield. The authors summarized the influence of conservation tillage on soil organic carbon and soil physical and chemical properties, discussed its effect on agricultural productivity, put forward improvement suggestions based on the problems existing in the conservation tillage, and provided scientific basis for reasonable cultivation measures and agricultural management.
