Abstract
Bacteria and fungi identification is very crucial in other to understand their roles in soil structure formation and plant growth. The distribution of bacteria and fungi is diverse, and varies greatly across different environment, such as soil and water. However, the presence of various diversities of these microbes can be either harmful or beneficial to agriculture. Therefore, this work was conducted to identify the various diversity of bacteria and fungi in the soils of the study area. The microbial count ranged from 3.2×106 to 6.7×106 for bacteria (0-15cm) and 1.7×104 to 4.3×104 for fungi (0-15cm). For 15-30cm, bacteria ranged from 1.2×106 to 3.0×106 and fungi ranged from 0.2×104 to 2.7×104. It was observed that the microbial population was greater in top soil (0-15cm depth) and reduces down the soil profile (15-30cm depth). The diversity of bacteria species identified incudes: Pseudomonas sp, Bacillus sp, Nocardia sp, Clostridium sp, Proteus sp, Micrococcus sp, Staphylococcus sp and Klebsiella sp. While the diversity of fungi species identified includes: Cladosporium sp, Aspergillus sp, Pichia sp, Fusarium sp and Penicillium sp.
