Soil Pollution
Soil pollution is standing up as an havoc in densely populated and developing countries. Since soil-formation is slow it is regarded as non-renewable resource. Soil pollution is the effect of dumping and disposal of wastes, application of agrochemicals or indirect result of air pollution (acid rain).
Pesticides reduce the population and number of species of living organisms which effect structure and fertility of the soil. Several pesticides and their degradation products enter the food chain via. plants.

Improper sanitation and unhygienic practices of the people of developing countries pollute the soil. Innumerable pathogens present in these wastes contaminate the vegetable crops and cause several health hazards for man and domesticated animals. Biological sources are a minor factor in altering soil composition.
