 Effects of Tillage Methods on Soil Organic Carbon and Total Nitrogen Content in the Loess PlateauTingting Meng Asian Agricultural Research, 2020, vol. 12, issue 02 Abstract: In order to determine whether long-term no-tillage operation in the loess plateau threatens soil fertility and crop yield, a suitable high-yield and efficient tillage technology system was established. In the Changwu loess plateau agri-Gecological experiment station of the Northwest A&F University of Changwu County, Shaanxi Province, the no-tillage experimental field for three consecutive years was selected. In September 2015, no-tillage, tillage, and rotary tillage were carried out before winter wheat was sowed. After the harvest of winter wheat in 2016, soil organic carbon, total nitrogen and wheat yield in 0-30 cm soil layers under different tillage methods were analyzed. The results showed that the soil organic carbon and total nitrogen contents in the 0-30 cm soil layer decreased along the profile under the three tillage methods. In this study, the soil organic carbon and total nitrogen content in the 0-10 cm soil layer under different tillage methods were no-tillage > rotary tillage > tillage, the actual yield of winter yield in one hectare was tillage > rotary tillage > no-tillage, and there was significant difference in the actual yield of winter wheat only between the no-tillage and tillage.
