Abstract
Soil enzyme activities and bioloads of various organisms as influenced by Cattle Market activities were evaluated in Okigwe, Imo State. All the bacterial groups estimated have their highest values in the soil in which the slaughter house wastes were disposed while the control was the least. Lipolytic bacterial counts ranged from 1.7 x 10 3 – 2.1 x 10 4 cfu/g; proteolytic bacteria 2.1 x 10 3 – 1.7 x 10 5 cfu/g and total coliforms were 2.3 x 10 4 – 2.7 x 10 5 cfu/g. The total heterotrophic bacterial count ranged from 3.7 x 10 6 to 3.7 x 10 8 and nitrifying bacteria 2.1 – 10 4 – 3.7 x 10 5 cfu/g. The soil pH changed towards slight alkalinity (6,4-7.6) while the change in temperature was not significant (28.2 – 30.4oC). The total organic carbon, nitrate and phosphate were in the order of control -1 ). The order for dehydrogenase and phosphatase activities were Market soil> slaughter house waste soil > Control while lipase and urease had slaughter house waste soil > Cattle Market soil > Control. Cellulase activity was also higher in cattle market soil than slaughter house waste and control. The activities caused increase in both bacterial loads and enzyme activities.
