Long-term single tillage causes serious deterioration of land quality and reduction crop yield. Tillage rotation can alleviate the problems caused by long-term tillage. However, effects different rotations are still very limited. A experiment was conducted in North China Plain to evaluate impacts on soil organic carbon (SOC), total nitrogen (STN) There were eight treatments with two main factor...

Mechanical subsoiling is an effective practice to promote better water infiltration and crop root development. The bending tool (BST) a primary used remove soil compaction restore productivity. In this study, discrete element model was developed validated using laboratory bin tests investigate the effects of mounting angle BST (5°–33°) on disturbance behaviors draft forces. results show that up...
