Influence of no-tillage on soil physical properties and crop production

As an important soil management practice for agriculture production,no-tillage could increase soil moisture storage,improve fertility,prevent particle from agricultural land,reduce soil and water loss and accelerate agriculture sustainable development.It has already proved that no-tillage played an important role in arid and semiarid areas of China.However,the regional eco-environment,climate types and agricultural production technology differ in various spacia-temporal scales,associating with the difference in land utilization patterns.The influence of no-tillage on the soil physical properties and crop production also presented distinguish in region-spatial and temporal patterns.In this review,the effects of no-tillage on the soil physical properties and crop production were summarized and synthesized; meanwhile,the existing questions of continuous application for no-tillage in China were analyzed,and also the possible suggestions were put forward.The results from this review provided references for optimal application of no-tillage in different regions and supports for the mechanism involving conservation tillage reduce soil erosion.
