Sorghum Yield Adaptation to Climate Change in Eastern Sudan

 Ridges and mini-depressions along the contour create small storage volumes where rainwater can accumulate, allowing more time for infiltration and reducing erosion. Mulching is a protective soil covering to reduce evaporation, maintain even soil temperature, prevent erosion, control weeds and enrich the soil. Mulching and contour tied-ridging provide more water storage and soil organic matter enrichment.
