Abstract

Soil is the solid material on the earth surface that results from interaction of weathering and biological activity on the parent material or underlying hard rock. This study was aimed at assessment of physico-chemical properties, bacterial and fungal load of Agrochemical farm soil in Jahun metropolis, Jigawa state. In this study, temperature, pH, moisture content, electrical conductivity, organic carbon, heavy metals and elements of the soil were assessed accordingly. Bacterial and fungal load were also determined using pour-plate methods. The temperature ranges between 14 to 30OC. pH value ranges from 6.72 to 7.79, the moisture content ranges from 0.67% to 1.69%. The percentage of organic carbon range from 0.13% to 0.41%, whereas the electric conductivity ranges from 0.04 to 0.05 respectively. Sample from NPK and manure treated farm presented the highest bacterial count of 3.81× 107cfu/g with the lowest in the NPK treated farm of 2.50×106cfu with no growth in the control river sand, whereas the control showed the highest fungal count of 3.20×105cfu/g with the least in NPK treated farm. In conclusion this study revealed that inorganic and organic management of the farm soil affect its physicochemical properties, size and activity of microbial population.
