Abstract

This article presents a comparative analysis of changes in the general physical properties of typical gray soils under conventional tillage and NoTill technology in rainfed lands. Under conventional tillage, soil compaction increases, with bulk density rising to 1.30–1.44 g/cm³ and porosity decreasing to 47–52%. In contrast, the application of No-Till reduces bulk density to 1.25–1.37 g/cm³, while porosity remains within 46–50%. It was also found that slope exposition significantly affects the soil water-air regime. The results indicate that No-Till technology improves soil structure and reduces surface water erosion. This technology has been proven to support sustainable agriculture in rainfed areas, ensuring environmental safety, resource efficiency, and long-term soil productivity.
