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

What Is Soil Pollution? [pic] What Is Soil Pollution? Soil pollution results from the build up of contaminants‚ toxic compounds‚ radioactive materials‚ salts‚ chemicals and cancer-causing agents. The most common soil pollutants are hydrocarbons‚ heavy metals (cadmium‚ lead‚ chromium‚ copper‚ zinc‚ mercury and arsenic)‚ herbicides‚ pesticides‚ oils‚ tars‚ PCBs and dioxins. Until the 1970s‚ there was little talk of soil pollution and its devastating effects. In the 1980s‚ the U.S. Superfund was

What Is Soil Pollution? Soil pollution comprises the toxic waste of soils with resources‚ mostly chemicals that are out of place or are present at concentrations advanced than normal which may have unpleasant effects on humans or other organisms. However‚ soil pollution is also caused by resources other than the undeviating addition of man-made chemicals such as undeveloped runoff waters‚ industrial waste materials‚ acidic precipitates‚ and radioactive clash. Both organic and inorganic contaminants

Soil Pollution The process of contamination of the land surface of the earth is referred to as land pollution. It results from human activities that cause imbalance in nature. Dumping human and industrial waste harmful agricultural practices and exposing the land to harmful chemicals leads to the pollution of land. We speak of water and air pollution and rarely even think of the adverse effects of land pollution. Let me share with you some of the important facts about land pollution. Land

Soil and its types: What is the Soil? ‘Soil’ is the thin layer on the surface of the Earth on which the living beings survive. Soil is the layer which is composed with many substances; in this layer various plants have their roots. Soil is made of many substances like weathered rock particles‚ and decayed plant and animal matter. Soil is made of diverse materials like broken down rock particles and organic material. There are different types of soil and various ways to classify it. Classification:

A soil horizon is a layer parallel to the soil surface‚ whose physical characteristics differ from the layers above and beneath. Each soil type has at least one‚ usually three or four horizons. Horizons are defined in most cases by obvious physical features‚ chiefly colour and texture. These may be described both in absolute terms (particle size distribution for texture‚ for instance) and in terms relative to the surrounding material‚ i.e. ‘coarser’ or ‘sandier’ than the horizons above and below

Podzols In soil science‚ podzols (also known as podsols or Spodosols) are the typical soils of coniferous or boreal forests. They are also the typical soils of eucalypt forests and headlands in southern Australia. The name Podzol is derived from the Russian words pod = under and zola = ash. Characteristics of Podzol soils - Deep organic layer comprising L (litter)‚ F (fermenting organic matter) and H (humus) forest‚ less under moorland - An ash-grey‚ structure less‚ silica rich E or elluvial

Types of Soil & Their Uses Soil is a complex system of organic and inorganic matter that directly and indirectly supports plant and animal life. It is comprised of minerals‚ nutrients‚ water‚ microorganisms and decomposed living matter that provide the essential elements required to sustain growth. The soils of different geographical areas differ in chemical makeup‚ structure‚ pH value‚ texture and color. Soil makes the basis of the ecosystem and performs functions essential for the survival
