Types of soil pollution can be distinguished by the source of the contaminant and its effects of the ecosystem. Types of soil pollution may be agricultural pollution, Industrial wastes and urban activities.
Agricultural Pollution
Agricultural processes contribute to soil pollution.
Fertilizers increase crop yield and also cause pollution that impacts soil quality.
Pesticides also harm plants and animals by contaminating the soil.
These chemicals get deep inside the soil and poison the ground water system.
Runoff of these chemicals by rain and irrigation also contaminate the local water system and is deposited at other locations.
