The soil is polluted by several means. The soil is eroded by different natural factors like the flood, volcanic eruption, rainfall, and wind flow etc. Due to flood soil is eroded and become unproductive. Plant cannot grow on that soil. Rainfall and wind, in the same way, erode the upper layer of the earth and make the soil.


Main Causes of Soil Pollution

  • Industrial Activity
  • Agricultural Activities
  • Waste Disposal
  • Accidental Oil Spills
  • Acid Rain etc.

Several activities of human beings, cause the soil to be polluted. Destruction of forests and plants, excessive cultivation and irrigation cause soil pollution. If there is no plant and cultivation is done in excess, it will erode the fertile layer of the soil surface and thus soil will become non-fertile. Excess irrigation causes waterlogging and makes the soil saline. Underground salt being dissolved in water come to the surface and make the soil non-fertile. Various types of waste materials are one of the causes of soil pollution. Harmful chemical substances and substances that are not absorbed by nature (e.g. polythene, plastic etc.) cause soil pollution. When the soil is polluted no plants, insects or microorganisms can grow on it. As a result, the soil becomes unproductive and unfit for human habitation. To keep the natural environment balanced a fertile and productive soil is necessary. Therefore, we all should take care so that the soil does not get unfertile and polluted. One of the ways to protect soil pollution is to plant more and more plants. There should have necessary laws so that industries do not leave their wastes here and there. If we all are careful against soil pollution it is possible to prevent the pollution.
