Question

Control of soil pollution​

Answer 1

Here is ur answer:

Soil pollution is defined as the build-up in soils of persistent toxic compounds, chemicals, salts, radioactive materials, or disease causing agents, which have adverse effects on plant growth and animal health.

Soil is the thin layer of organic and inorganic materials that covers the Earth’s rocky surface. The organic portion, which is derived from the decayed remains of plants and animals, is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments, was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient food.

There are many different ways that soil can become polluted, such as:

a. Seepage from a landfill

b. Discharge of industrial waste into the soil

c. Percolation of contaminated water into the soil

d. Rupture of underground storage tanks

e. Excess application of pesticides, herbicides or fertilizer

f. Solid waste seepage
