ABSTRACT
This study
evaluated microbiologically, the effect of soil erosion on microbial
communities [based on soil microbial load. In the course of this study, soil
samples were obtained from three ; different erosion sites Umuobia, Amuzukwu
and Isieke-lbeku, with three (3) soil samples I obtained in each erosion site
from the Upper Slope, Middle Slope and Lower Slope and in ! addition to them,
two other soil samples (Agricultural soil and Trampled soil) were obtained I
and used as controls. From this study, the mean microbial counts from the
samples analyzed I revealed that Agricultural soil had the highest bacterial
count at 1.37x10°, followed by the 1 Lower Slope soil samples of the eroded
sites, and the least bacterial count was recorded in the j Middle Slope of the
eroded soil samples. The total fungal plate count investigated revealed
{Agricultural soil as having the highest fungal count ( 1.26x 10 ) and the
Middle Slope of eroded ' soil samples as having the least fungal count
(0.00x10). Bacterial strains were isolated using ; the spread plate techniques
and were identified using colonial morphology, Gram staining ' reaction,
biochemical and motility tests which revealed the major bacterial isolates to
be Bacillus species, Pseudomonas species, Aclinomycetes species, Staphylococcus
species and Escherichia coli while microscopic and colonial morphology revealed
the fungal isolates to be Aspergillus niger, Fusarium solani, Fusarium
oxysporum. The percentage occurrence of bacterial isolates showed Bacillus
species as the most frequently occurring at 6(30%) while percentage occurrence
of fungal isolates revealed Asper gillus niger as the highest occurring fungi
at 5(45.5%).
