Soil is the layer of broken rock particles and decaying organic matter on the surface of earth‚ which is essential for the growth of plants. It comprises of all the necessary nutrients that aid the growth and development of plants and trees. There are different types of soils‚ each one of them varying in its nature and texture. While some soils are deep rooted‚ the others are present on the margin. They also differentiate in their color‚ as some may be red while others are black. There are various

SOIL POLLUTION INTRODUCTION 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

Soil Degradation The damaging process of soil particles being moved and cycled by water or wind is known as erosion. Soil erosion can occur anytime soil is bare or exposed and naturally removed by wind or water. This form of soil degradation is a natural process but it further elevated by human activity. Human disturbances of the soil allow for this process to happen more rapidly under natural conditions. According to the University of Michigan‚ whose geologist conducted a study‚ human actions

Soil scientists are interested in soils as a medium for plant growth. So soil scientists focus on the organic rich part of the soils horizon and refer to the sediments below the weathered zone as parent material. Classification is based on physical‚ chemical‚ and biological properties that can be observed and measured. Soils engineers think
