Abstract
The objective of this study was to determine the impact of municipal solid waste (MSW) treatment techniques on the soil Chemical properties of Sudan Savannah, Nigeria. MSW was collected from multiple metropolitan sites and mixed together. The composite sample was used to produce biochar and compost treatments. The effect of MSW treatment techniques on the qualities of soil was assessed by applying treatments and controls (untreated MSW) to soil at various rates. Soil samples were collected four weeks after treatment application, processed and analyzed in the laboratory. Results showed significant difference (*P≤0.05) in soil Mg and Zn, as well as highly significant difference at (**P≤0.01) in soil EC and K values. Biochar is recommended for acidic soil to improve soil pH, whereas compost is suggested for increasing soil organic matter and microbial activity. The use of untreated MSW is primarily advised for long-term soil deterioration solutions.
