摘要：This study was aim to investigate the effects of land use on the nature and population of microorganisms in soil from five different farms within University of Maiduguri, Borno State. A total of ten composite samples were obtained and analyzed in the laboratory. The total microbial population was consistently higher in the grazing reserved land with mean of 105x10 4 CFU/g than in cultivated farms with means of 84.5x10 4 CFU/g, 66x10 4 CFU/g and 66x10 4 CFU/g, for cereal (sorghum), beans and tomato farms respectively. The site with the least microbial population was gum-Arabic plantation with the mean of 29x10 4 CFU/g. Bacteria were the most dominant species at all sites regardless of depths.
