Abstract

The coffee industry is located in Jayamangalam near Periyakulam, Theni District. The soil was collected from dumping site of coffee effluent, to analyse the physico chemical parameters during January-May, 2017. It was analyzed using standard methods. The pH of the sample was alkaline in nature. The value of electrical conductivity was higher than the permissible limit. The amount of available nitrogen, phosphorous and potassium concentration was also high. Heavy metals such as Zn, Fe, Cr, Cu, Mg, Pb and Mn were also analyzed. This soil contains high amount of heavy metals where Cu followed by Magnesium was the highest among them and exceed permissible limits. The effluent from the coffee industry was the major source of pollution which will affect the flora and fauna existing in such soil environment. Thus, there is need for treatment of coffee industry effluent before they are discharged into the soil environment.
