چکیده:
Soil pollution is one of the types of environmental pollution. Soils are as cathartic in nature.
In addition to being suppliers of food, it has also refined property. This property can be
obtained due to their physical properties, chemical properties and biological properties. One
of the major concerns of today's agriculture is soil contaminated with pollutants harmful to
human. Soil pollution is as a major environmental problem in the known world. Various
sources of pollution such as agricultural pollution, oil pollution, heavy metals, industrial
wastes and so reduce the quality of the soil, spread in groundwater levels and the incidence
of other environmental problems. However, the lack of proper management of organic waste
can lead to the increase of concentration of salts, heavy metals, pathogenic microorganisms,
soil pollution, water pollution, agricultural products, fish etc.

Importance of soil In addition that soil is an important component of achieving sustainable development, the following functions are considered: • Sustaining biological activity, diversity and productivity • Setting the water flow and solute transport division • Filtering, buffering, reducing and detoxifying organic and inorganic materials, including municipal solid waste and urban waste and atmospheric deposition • Storage, cycle nutrients and other elements in the biosphere Identifying and predicting soil contamination Unlike air pollution, the chemical composition of soil pollution is not easily measurable, even if the presence of harmful substances and hazardous compounds in soil is approved; but if the soil is disturbed normal function, this disorder can be well observed because the quality of plant, for example, the desired product is reduced and compounds and elements are found to be inappropriate or excessive.
