ABSTRACT

This study was carried out to assess the abundance of soil microorganism under the influence of tree species of Acacia senegal, Balanites aegyptiaca and Faidherbia albida. The experimental design used was 3x2 factorial in CRD (Complete Randomized Design). The two factors were three tree species of Acacia senegal, Balanites aegyptiaca and Faidherbia albida; two soil depth levels (20cm and 40cm) and control (0cm) were studied. The result had shown that Balanites aegyptiaca had the highest number of bacteria and fungi with means of 1.97E+18a and 2.43E+14a respectively. Acacia senegal had the highest number of nematodes with a mean of 1062.5a but lowest in terms of number of bacteria and fungi with a mean of 1.25E+18b and 2.20E+14a respectively. Balanites aegyptiaca gave the lowest in terms of number of nematodes. Soil depth of 20cm performed better in the number of nematodes and fungi found in the soil with a mean 1068.8a and 2.16E+14a respectively while 40cm depth had the highest in the number of bacteria with a mean of 1,56E+18a. In conclusion Balanites aegyptiaca was observed to have the highest impact on the abundance of these microorganisms followed by Acacia senegal with prevalence of the microorganisms in the 20cm soil depth. It is recommended that Balanites aegyptiaca be used in research requiring the study of fungi, bacteria and nematodes in soils and samples to be collected at the depth of 20cm.
