Resumo

This study assessed degradation status of erosion devastated soils as well as ameliorative measures on such soils. Field sampling was aided by morphological landscape changes. Surface samples (0-20 cm) depth were randomly collected from two erosion units and used in conducting a greenhouse experiment using maize (Zea mays L.) as a test crop. The experiment was laid out in a completely randomized design (CRD) and rates of ground periwinkle shells (GPS) and sewage sludge (SS) used as treatment. Treatments were replicated 9 times. Statistical tests of difference in soil properties were performed using t-statistic at p < 0.05. Status of soil degradation was evaluated using Land Degradation Index (LDI). Results showed low organic carbon content, and high bulk density and aggregate instability in eroded soils. The LDI values were high in most of physical parameters. The GPS and SS treatments significantly (p < 0.05) improved yield and soil properties except soil pH and aluminium saturation.
