Natural resources, soil, a thin layer of organic and inorganic materials, the rocky surface of the earth. Bottoming out with a number of factors and time a. mechanical weathering of rocks by changes in temperature, wind, flowing water is connected, lichens are a few factors.
Pollutants, poisons, radioactive materials, salt, chemicals, if the deterioration of soils, soil texture and mineralogical composition was added. The biological balance of soil pollutant-degrading soil organisms. The negative effects of this pollution is low soil fertility, plants and animals, affecting growth.
The main causes of soil contamination are:
The occasional use of fertilizers
The occasional use of pesticides, insecticides and herbicides
Disposal of large quantities of solid waste
Deforestation and soil erosion
In the industrial pollution
Radioactive waste
Control of pollution
Various measures to control pollution of the soil are:
Reduction of chemical fertilizers and pesticides:
As soil erosion has become a major concern, we have three R’s: Reduce, Reuse, Recycle, to minimize the use of fertilizers and pesticides.
Thor are better alternatives to chemical fertilizers. These are microorganisms that are used to increase the fertility and the ability of soil to increase. This process also reduces the need for pesticides and fungicides in Biofertilization.
Practice of crop rotation – legumes can fix nitrogen from the air and thus to improve soil fertility. These plants can be grown in soil in cultures that consume a lot of nutrients.
Recycling
Recycling and reuse of materials such as glass bottles, plastic bags, paper, fabric, etc. at home instead of recycling, reducing waste pollution. The use of plastic bags has increased dramatically. Paper bags or jute bags is a good alternative for them. Clay toys can be a good source of entertainment for children.
Reafforestation
Heath, soil erosion and flooding can be controlled through afforestation. Vast forests have fallen victim of human greed. Everyone would decide on the earth, to plant trees to save the planet Earth.
Recycling
The biological treatment of wastes with anaerobic bacteria, such as methane and acetogenic recommended because it helps to go through and to less toxic organic forms.
It is time that people realize the importance of the rich and fertile ground for measures to prevent infection. Large parts of the desert, laughing with the people has created us. If you do not build tanks and containers fertile by nature, if they do not stop their destruction?
