Abstract
The purpose of this study was to assess the quality of compost obtained from ten (10) municipal solid waste dumps in the Sokoto metropolitan area, Nigeria. The Compost was characterized to understand its fertilizing and polluting potential to soil. The fertilization index (FI) was determined empirically from the values of TOC, TN, TP, TK and C:N ratio and the cleaning index (CI) using heavy metal concentrations. The results were compared with quality control metrics. The FI values for the composts ranged from 4.00 to 4.70, while the CI values ranged from 2.60 to 4.00, respectively. Most of the MSW composts analyzed showed good fertilizing potential and were of good quality for use as soil fertilizers.
