Soil contamination Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity‚ agricultural chemicals‚ or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons‚ polynuclear aromatic hydrocarbons (such as naphthalene and benzo(a)pyrene)‚ solvents‚ pesticides‚ lead‚ and other heavy metals. Contamination is correlated with the

Introduction Every type of soil has its own percentage of moisture content. The void in soil content water and air. The moisture content may varies for each types of soil. Different type of soil has different moisture content. Moisture content of soil also may be affected by the climate where the high humidity country tend to have higher moisture content in soil. Size or structure of the soil particles also affecting the moisture content. The properties of the soil to retain water also one of the

management can affect soil characteristics as well as soil quality. The term soil quality can be defined as the overall activity of a soil within an ecosystem that preserves biological activity and environmental quality‚ thus promoting plant and animal health (Doran et al. 1994). Alterations in soil properties and processes can affect functions that soils perform in the environment‚ which in turn influence patterns of plant growth (Ahuja 2003). Changes in land use influence several soil processes‚ such

Evaluation of the soil management strategies in the India The more time goes past‚ the more man starts realising how the management and the way we threat soils is important to insure its preservation and conservation. Nowadays‚ around 9.4 million hectares of soil‚ which represent the 0.5% of the land present on our planet‚ is irreparably damaged and has no longer any biological function. In other words‚ it can no longer be used in any useful way to provide food or other elements to the earth’s

3 Throughout the world soil is constantly being eroded. There are three major principles that can cause soil to erode‚ leading to soil degradation. Over-cultivation‚ overgrazing‚ and deforestation have huge impacts on the degradation of the soil. There are‚ however‚ actions that can be taken to preserve or correct the conservation of soil. To further understand the prevention of degradation‚ we must fully comprehend the major causes of soil erosion. One major cause of soil erosion is over-cultivation

Outline the most serious threats posed to the physical environment and vulnerable populations by soil degradation Soil degradation is the decrease in the quality and quantity of soil caused by agriculture and industrial purposes. Types of soil degradation are water and wind erosion‚ physical degradation and chemical degradation. Some of these are human causes and some are physical causes. Overgrazing‚ deforestation‚ overpopulation‚ fertilizer and pesticide use and conflict are some examples of
