Soil provides habitat to animals, plants, insects, humans and as a whole living organism so it is considered to be a vital part for living beings. Soil helps to provide the necessary moisture and minerals to support the plant that prevents many natural disasters. Also, many microbes make their existence on the soil.
Soil pollution is the degradation of soil due to the presence of various unwanted chemicals that alters the natural state of the soil. It degrades the quality of soil and makes it unsuitable for plants as well as other living organisms. The excess use of chemical fertilizers, pesticides, insecticides and other has degraded the quality of soil and its natural capacities. Soil pollution is mostly seen in the areas where urbanization is high and industrialized areas. Hence, when the chemical and physical properties of the land changes and cause harm to living organisms, it can be considered as soil pollution.

Measures to Control Soil Pollution
Conservation and Management of Forest
Forest is one of the major factors to play role in balancing the ecosystem and providing habitats to various animals and microorganisms. Places with a high number of trees do not suffer from natural calamities such as floods, landslides, etc. Forest causes rainfall which is very important for the plants to survive.

But, in the present days, people have been cutting down the trees for their benefit which is causing an imbalance in the surrounding environment. Some of the major ways to conserve forest are listed as follows:
Any undesirable change in the chemical and physical properties of soil which causes direct or indirect effects in the living organisms is said to be soil pollution.
The major sources of soil pollution are:
We can control the soil pollution by following the listed measures:
Forest plays a vital role in balancing the ecosystem. It is very important to conserve forest resources. Following are some of the measures that can be implemented to conserve and manage the forest resources in Nepal:
