Abstract

This paper presents soil erosion responses to four different land use types in Maiduguri and environs.  Representative of four soils from Dalori, Chad-basin, Jimtilo, and Domboa-road areas of Maiduguri were selected for the study. The four land uses studied were cultivations of orchard, cereal, and leguminous crops alongside bare soil which served as a control. They are representatives of land use practices found throughout Maiduguri and its surrounds. The samples were subjected to rainfall from stationary rainfall simulator. Results showed runoff volumes, soil loss and soil erodibility varied with land use types and locations. Runoff volumes, soil loss and soil erodibility were all higher in cereal crop-cultivated lands, and least in leguminous-crop cultivated lands. Parallel to that, runoff, soil loss and soil erodibility were highest from soils taken from Dalori area, and they were least from soils collected from Chad basin area. Leguminous cropped areas were found to be more effective in binding soil particles than tree crops. Cereal crops demonstrated poor soil binding effectiveness. The study shows that land use changes influenced the soil erosion risk and called for adoption of appropriate soil conservation techniques to preserve the soil quality, improve crop production and sustain environmental health.
