The study looked at different ways of preparing soil for growing winter wheat on sloped land in China. They compared methods like reduced tillage, no-till, and subsoiling to see how they affected soil water conservation and wheat yields. No-till and subsoiling were the best at keeping water in the soil, leading to higher wheat yields. These methods also saved energy, reduced labor, and increased profits. Overall, no-till and subsoiling are promising ways to improve water availability and crop yields in dryland farming.
