The Cause Of The Pollution Of The Soil
In General, the causes of soil pollution can be distinguished into two factors, i.e. factors of man-made and natural factors. That included man-made factors include pollution caused by waste (pollutants) generated from any human activity, such as garbage disposal, use of inorganic pesticides and inorganic fertilizers, as well as the disposal of liquid waste into ground. While the natural factors included covering pollution caused naturally by natural phenomena, such as acid rain.
- Inorganic waste disposal
Inorganic waste disposal into the body of the land is a major cause of soil pollution. Inorganic trash such as trash-broken glass, plastic, metal, rubber and material will be difficult by soil microorganism decomposes in a short time. The existence of these junk-junk ultimately may decrease levels of soil fertility and land use resources. Plants can not live in such environment so that will can disrupt the balance of micro-ecosystem in the long periods of time.
- The Use Of Pesticides
In massive use of pesticides on land-agricultural land would leave residues in the form of inorganic toxins. The residue will make the demise of soil organisms, either in the form of microfauna, mikroflora, makrofauna, and makroflora.
Soil with a low biological fertility rate due to the death of the microorganism of the soil will make power land use as a place of living plants as organisms are producers not maximum. Damage to the ecosystem balance order will occur in massive land pollution cause when it is not be solved, for instance by converting the use of pesticides or organic pest control diseases are integrated.
- The Use Of Inorganic Fertilizers
In addition to pesticides, inorganic fertilizers are always used in the agricultural industry is also the cause of land pollution that needs serious attention. The use of inorganic fertilizers are actually aimed so that the plant can grow optimally will leave residue which affects the damage of soil structure and fertility level of the soil.
- Liquid waste disposal Industry and households
The cause of the pollution of the ground is the disposal of a variety of household liquid waste like leftover detergent and SOAP, as well as the industrial liquid waste to the land. This kind of wastes could not be described in a short period of time by microbial soil. It is caused due to the microbial mikorba-thus will die due to the nature of the toxic liquid waste that is owned.
- Hoarding A Compound Acid
Acid rain due to the volcanic ash volcanic eruptions result raises quite serious side effects in a broad area of coverage for damage to the soil. The acid content is too high on rain water makes soil pH will decrease drastically. As a result, the soil microorganism was not able to adapt will die. In addition, soil structure will also undergo change and cause plants to become incapable of survival..
