Soil pollution is the high buildup of toxic chemicals that cause human health and ecosystem risk. Soil Pollution also affects physical, chemical and biological property of soil and reduces the crop production capacity of soil. Pesticides, fertilizer, organic manure, chemicals, radioactive wastes, wasted food, clothing, leather products, plastics, paper, bottles, tins-cans, and corpses are all part of the soil contamination problem. Chemicals such as iron, lead, mercury, copper, zinc, cadmium, Aluminum, cyanides, acids, and alkaline, among others, are found in industrial wastes and reach the soil either directly or indirectly through water and air, Example acid rain. The presence of poisonous material in soil in a high enough amount to cause a risk for the soil environment and our ecosystems is called "soil pollution." Soil pollution occurs when the amount of contaminants in the soil exceeds its natural level. There are generally two main causes of soil pollution:
