Abstract
This paper is an effort to be carried out to investigate the large amount of waste products generated from industries producing sugar, Chocolates, spirit, paper ,etc.,in Nellikuppam town located at Cuddalore District .The soil samples were collected from in and around the Nellikuppam town and analyzed the physical parameters of the soil such as, electrical conductivity and the chemical parameters such as pH, macro nutrients (Available Nitrogen, Phosphorus, Potassium) & micronutrients (Zinc, Copper, Manganese, Iron).These macro and micro nutrients are analysed by Atomic Absorption Spectrometer(AAS).The results were obtained and compared with the standard values of critical limits available for fertility of Agricultural Purpose. Electrical conductivity ,pH and amount of copper present in all the soil sample were within the critical limits. Slight abnormal changes were observed in chemical parameter like Available Nitrogen, Phosphorus, Potassium, Zinc, , Manganese, Iron due to the presence of some impurity in soil .
