Abstract

Effect of waste water execrated from milk dairy on to the soil physicochemical, biological and enzymatic activities like protease, phosphotase was studied in the present study. Discharge of dairy milk effluents alters the physicochemical, biological and enzymatic activities. These changes included increased in pH, water holding capacity, electrical conductivity, Carbon, Nitrogen and Phosphorus in contaminated soil. Higher bacterial and lower fungal populations recorded in the polluted soil. Increased protease, phosphotase activities were observed in soil discharged with dairy waste water from the industry.
