Any substance within the soil that will increase above its ordinary stage can come to be harmful to people and surroundings is referred as Soil pollution. Human life is exceedingly depend upon soil. Soil pollution is growing every day and have become a rather regarding matter.

Estimated Polluted Areas:-
According to Chinese government in 2015,it is envisioned that approximately 16% of Chinese soil are polluted the contribution to the soil pollution. In European Economic Area and Western Balkans is about equal to three million. The United States of America has greater than 1300 polluted sites.In Australia, it's far expected that the  sites are of 80000.

Reasons Of Soil Pollution:-
Both the natural and human activities can reason soil pollution. Natural elements of soil pollutants can be from the eruptions of volcanos and weathering. However the adaptation ability and regenerative capacity of flora make this threat much less problematic to environment. Then what's the real cause?
  1) Industrial Activities
Industries are the most important contributor of gaseous pollution to environment and soil. Manufacture Industries like glass, textiles,rubber manufacturing, pigment manufacturing,soap and detergent,leather-based manufacturing are some of the examples. These toxic and the incredibly polluted gas  exhibited from the industries directly enter air and water bodies. The pollutant in the atmosphere  input the soil without delay through acid rain.

  2) Mining
Mining can contribute to soil pollution in the form of heavy metallic and other poisonous wastes. These wastes can pollute soil within the shape of heavy metals and different poisonous wastes. These wastes can pollute soil through the erosion of wind and water. The wastes consist of chromium, nickel,spills of crude oil and brains.
  3) Increased Transportation Facilities and Urbanization
Urbanization has massive effect on soil pollution. Increased infrastructural facilities is a main pollution contributor and it is much less considered in planning and impact evaluation. The pollution associated with transportation is because of the emission of gas from engines.These can cause excessive environment pollution like smoke,fog,smog, and many others.
One of the major soil pollutants get up due to urbanization is plastic.It persist in surroundings for a long term.The polymers found in plastic could be very tough to decompose inside the soil hence becoming a major pollutant.
  4) Generation and Disposal of Water and Sewage
Electrical and electronic equipment subsequently became waste as they're no longer functioning. They are drastically growing hazardous waste and need to be considered as threat. One of the harmful scenario is created by means of lack in municipal waste control.
Top hazardous chemical compounds including poly-aromatic hydrocarbon, heavy metals, private care, and pharmaceutical compounds attain soil and groundwater at once from landfills. These pollutants can cause pollution of groundwater and impact food chain. Wastewater is some other issue regarding with soil pollutants.

The contaminants like heavy metallic, salts and pathogens are deposited until water is treated nicely.Recycled waste water is used for agricultural purposes in many nations like Israel and Pakistan.
  5) War and Military
War and military activities produced soil pollution to a great extent in last century. Modern equipments used for war and military activities are made from non degradable and risky chemical substances which persist soil for long time. However there's a limit positioned by  governments for publishing evidences of pollution caused by this factor.
  6) Agricultural Activities
The increased use of insecticides and fertilizers had contributed soil pollutants to a tremendous extent. The wastewater and urban sewage can cause lower in productivity of crops and impair plant metabolism. The agrochemicals containing trace metals like Cu, Cd,Hg and Pb which ends up in decrease the crop production and plant metabolism,soil salinity and water eutrophication
The increase and advancement in human population is causing soil pollution to a great extent. Studies and research have shown that soil pollution is increasing in rural and urban areas,had attained a alarming state. Soil pollution can cause dangerous health problems in human beings. Even new born babies can affect serious health issues.
