ABSTRACT
The present study aim is to determine soil
microbial biomass as affected by amendment of the soil with organic and
inorganic fertilizers: Soil amendment affect the growth of microorganism. From
the result the organic treatment (B) had the highest total viable plate count
2.41 x 108 to 8.4 x 10'followed by organic and inorganic treatment (D) 1.79 x
10 to 7.5 x 10', then followed by inorganic fertilizers (C) 7.1 x 10 7 to 3.4 x
10' and next is A which is the control .2 x 10' to 6.7 x 10 4 • The result
shows Bacteria isolated which belong to the family E. coli, P. aeruginosa,
Klebsiella pneumonia., Streptococcus spp., Staphylococcus aureus., Bacillus
spp. and Micrococcus spp., and fungal isolates which belong to the family Asper
gillus spp., Pencillum spp., Trichoderma spp., Rhizopus spp. and Mucor spp. The
percentage occurrence of bacterial isolates, from the result E. coli, P,
aeruginosa and Bacillus spp has the highest occurrence of (20%) followed by
Klebsiella pneumonia and Staphylococcus aureus with (15%), while the least
percentage occurrence was in Micrococcus spp and Streptococcus spp with (5%)
and the percentage occurrence of fungal isolates, from the result Pencillum
spp. has the highest occurrence of (36.5%) followed by Asperigillus spp. with (27.3%)
and Rhizopus spp. with (18.2), while the least percentage occurrence was in
Mucor spp and trichoderma spp with (9.1 %). The pH of these treatments is right
for the growth of these crops. The best Soil pHs for overall availability of
nutrients plant growth and microbial processes is slightly acidic to neutral
(6.0-7.5). Organic manure achieves a high microbial load, high nutrient content
for soil, and this leads to higher growth of crops. Farmers should be
encouraged to use organic manure as a way of adding nutrients to the soil other
than the use of fertilizers.
