Agroforestry for soil fertility and sustainable agriculture in Sudan

This study was conducted in South Kordofan State where farming system stability and food security is threatened. The objective was to assess the effect of agroforestry in improving soil fertility, increasing crop productivity and supporting food security and sustainable farming. Accordingly, tree density forest compartments were divided into three strata. In each stratum random circular sample plots were laid out. A total of 21 sample plots were made. Tree performance, forage coverage and gum arabic production were measured for two seasons. Structured questionnaire was also administered to 50 households. Study results indicate that there was significant increase in crop productivity under Agroforestry, and also gum arabic production. Crop productivity was improved due to improvement in soil fertility and protection against wind erosion. The study concluded that agroforestry is suitable for improving degraded lands, improving soil fertility, and hence, food security and livelihoods.
