“…SU increased the amount of available water in the soil by reducing surface runoff, promoting crop growth, yield, and rainfall utilization efficiency (RUE), and improving the soil structure and physical properties. Furthermore, SU can be used on thick and compacted soil to reduce further soil compactness and increase plant productivity [ 13 , 14 ]. RT can effectively improve soil structure, reduce soil bulk density, and increase crop productivity [ 5 , 15 ].…”

Continuous tillage cultivation positioning trials can provide the basis for maintaining soil health, improving resource utilization efficiency and crop productivity, and achieving sustainable agricultural development. In this study, changes in soil stability and water–holding capacity characteristics were measured under different tillage cultivations from a multi–year microscopic perspective and analyzed to evaluate selected key indicators. Continuous monitoring of rainfall utilization efficiency and yield was carried out for five years. Here, we discuss the role of conservation tillage in buffering and stabilizing rainfall precipitation pattern on the fluctuation and uncertainty of soil water retention and water supply capacity and soil quality. The study was carried out on dryland areas of the Loess Plateau in northern China with eight tillage systems established in 2016: no–tillage (NT); no–tillage and straw (NTS); subsoiling (SU); subsoiling and straw (SUS); rotary tillage (RT); rotary tillage and straw (RTS); conventional tillage (CT); and conventional tillage and straw (CTS). All treatments were applied in conjunction with continuous cropping for five years. The evaluated soil parameters were mean weight diameter (MWD), geometric mean diameter (GMD), >0.25 mm aggregate content (R0.25) of water–stable aggregates (WSAs), soil moisture characteristic curve (SMCC), specific soil water capacity (Cθ), soil organic matter (SOM), rainfall utilization efficiency (RUE), and maize yields for five consecutive years. The MWD, GMD, and R0.25 of SUS were 27.38%, 17.57%, and 7.68% more than CTS (control), respectively. Overall, SOM, average annual RUE, and average annual yields increased by 14.64%, 11.89%, and 9.59%, respectively, compared with 2016. Our results strongly suggest that conservation tillage can considerably improve these characterization indicators. SUS was more effective than CTS in the 0–40 cm soil layer at hedging against drought in the area, stabilizing crop production, and achieving sustainable agricultural development.

Based on the problem of insufficient coordination of integrated machinery and technique configuration in the exploration of dry farming regions, a method of two-period comparative test was carried out in Shanxi Province, China. Zones of the effects of different treatments on straw coverage, soil moisture, emergence rate, seedling condition, yield, and benefit were monitored and analysed. The result was that the coverage before sowing decreased to below 55% after surface harrowing or rotary tillage in autumn by using dry farming technology in Northern China. The average number of emerging seedlings through surface tillage was larger than that without surface tillage by 1.7 plants/5 m; emergency rate was increased by 8.37%, and the increase in amplitude of grain yield reached 28% compared with that of traditional farming. Moreover, the input–output ratio reached 1:4.41. The experiments showed that the net income could reach RMB 1,251–1,401/hm2, and compared with traditional farming, operating cost was lowered by 23.1%–28.8%, and benefit was elevated by 48.8% with prominent cost saving and benefit increase. The study results will facilitate the improvement of water-saving and production-increasing technologies in Northern China and play a critical role in the development of agricultural cultivation and steady growth of agricultural output in this region.
