Abstract

This study presents an assessment of the water-physical properties of rainfed soils. Enhancing the fertility of rainfed soils and developing scientifically sound agronomic practices for the efficient utilization of soil moisture under water-limited conditions necessitate a comprehensive investigation of their water-physical characteristics. Key indicators governing the soil water regime include particle-size distribution, soil aggregate structure, total porosity, and soil organic matter (humus) content. These properties play a crucial role in regulating water storage, retention, and transport within the soil profile, thereby significantly affecting crop productivity, resource-use efficiency, and the long-term sustainability of agroecosystems in regions characterized by inadequate precipitation.
