Effect Of Cassava Mill Effluent On Soil Microorganisms And Physicochemical Characteristics With Depth:- Ordi, Friday C
ABSTRACT
The effect of cassava mill effluent on soil
microorganisms and the physicochemical parameters of the soil at various depths
were studied. The results revealed the bacterial isolates as Proteus spp,
Bacillus spp, Staphylococcus spp, Streptococcus spp, Clostridium spp,
Pseudomonas spp and Klebsiella spp, while the fungi isolates were Aspergillus
spp, Penicillium spp, Mucor spp, Rhizopus spp, Fusarium spp and Yeast cells
like Sacchromycetes spp. At various depths, there are significant differences in
the total aerobic bacterial counts at surface (7.25x108±2.92cfu/g), subsurface
(8.6xl08±2.79 cfu/g) and deeper sample counts (6.4xl08±2.67cfu/g). Total fungal
counts also showed significant differences at P<0.05 between the surface
(2.7X103±1.2cfu/g) and subsurface (4.9x103±3.1 cfu/g) sample counts as well as
between surface and deeper sample counts (3.3x103±1.3 cfu/g), while there was
no significant difference observed between surface and deeper sample counts at
P>0.05. The pH and the Cyanogenic glucosides, increased with depth while %N,
%OM, Mg, Ca, Moisture Content ratios, all decreased with depth. Cassava Mill
Effluent (CME) negatively affected the microbial populations and
physicochemical parameters of the soil around it at various depths. Hence, waste
generated in the environment should be properly treated before discharging them
into the environment.
