SOIL EROSION Janeen Uy I BS MANAGEMENT ES 10 J Submitted to: Dr. Severino Salmo III March 8‚ 2012 Soil is found on the Earth’s crust and formed through weathering and decay of organisms. It may be considered dirt to a lot of people but it is highly an important tool for our survival. The soil holds the roots of the plants where nutrients are stored. It is important since it enables the soil to store and regulate the flow of water‚ filters the pollutants and improves the soil’s quality

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

A General Essay on Bioremediation of Contaminated Soil Dana L. Donlon and J. W. Bauder‚ Professor‚ Montana State University-Bozeman MSSE Graduate Student and Professor‚ respectively Bioremediation is defined as use of biological processes to degrade‚ break down‚ transform‚ and/or essentially remove contaminants or impairments of quality from soil and water. Bioremediation is a natural process which relies on bacteria‚ fungi‚ and plants to alter contaminants as these organisms carry out their

Soil‚ which is one of the most important natural resources‚ is often less heeded. The importance of soil conservation is relatively less talked about as compared to the conservation of water and other natural resources. The almost-omnipresent soil is mostly taken for granted. Its omnipresence is ironically the reason behind us‚ human beings‚ taking it for a ride. We rarely even think of it as a natural resource that needs to be conserved‚ a part of the natural wealth that needs to be preserved.

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 is an important natural resource that covers much of the earth’s land surface. All life on earth depends on the soil as a direct or indirect source of food. Plants are rooted in the soil and obtain nutrients (nourishing substances) from it. Animals get nutrients from plants or from animals that eat plants. Certain microbes in the soil cause dead organisms to decay‚ which helps return nutrients to the soil. In addition‚ many kinds of animals find shelter in the soil. Soil contains mineral
