Natural resources, the soil is, the thin layer of organic and inorganic materials for the rocky surface of the earth. The bottom has a variety of factors and a time to process. Mechanical weathering of rocks by changes in temperature, wind, flowing water, lichens are a few factors.
Pollutants such as toxic chemicals, radioactive substances, salts, chemicals, when ingested on the floor, the deterioration of the quality of the content, structure and soil minerals. This leads to soil pollution. Soil contaminants disrupt the biological balance of the organism in the soil. The negative effect of this contamination is the fertility of the soil, which reduces influence the growth of plants and animals.
The main causes of soil pollution are:
* The random use of fertilizers
* The random use of pesticides, insecticides and herbicides
* Removal of large quantities of solid waste
* Deforestation and soil erosion
* Added industrial contaminants
* Introduction of radioactive waste
Control of soil pollution
Various measures proposed, soil pollution control:
Reduce the use of chemical fertilizers and pesticides:
As soil erosion has become a major concern, we must take the three Rs: reduce to Reduce, Reuse and Recycle, the use of fertilizers and pesticides.
Biofertilizers are the best alternatives to chemical fertilizers.
Practice of crop rotation – legumes can fix atmospheric nitrogen and thus to improve soil fertility.
Recycling
To eliminate recycling and reuse of materials such as glass containers, plastic bags, paper, fabric, etc. at the national level to reduce waste pollution. Use plastic bags has increased dramatically. Paper bags or jute bags can be a good alternative for them. Toys made of clay can be a great source of entertainment for children.
Reforestation
Wastelands, erosion and flooding can be controlled through reforestation. Vast forests have become the victims of the greed of man. Every person on earth should decide to plant trees to save our planet Earth.
Waste treatment
The biological treatment of wastes with anaerobic microorganisms such as methanogens and acetogenic is recommended because it the reduction of waste ground into a form less toxic and biodegradable helps. Industrial and radioactive waste must be properly before the soil can be treated. Large areas of man-made desserts laugh about us. If we should not build tanks and containers made of natural fertile ground not stop the destruction?
