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

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

Soil Porosity and Permeability GEO 101 LAB – Earth Science July 26‚ 2014 Soil Porosity and Permeability The focus of week three’s lab in Earth Science is to figure out the porosity and permeability of four different soil types: gravel‚ sand‚ potting soil‚ and soil from my back yard. This lab is designed to look at the porosity and permeability of these four soil samples. Porosity is basically the measure of how much of the soil volume is open space. Permeability is the measurement of how long

Soil and Its Components Research Paper SOIL AND ITS COMPONENTS Soil is everywhere. It is abundant throughout the earth and contains most of the worlds diversity. Soil is full of life. It is actually believed that a handful of soil may consist of more living organisms than there are on this Earth. GENERAL DESCRIPTION Soil is a natural body comprised of solids (minerals and organic matter)‚ liquid‚ and gases that occurs on the land surface. (Natural Resources Conservation Service‚ 2013)

SOIL Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3000 to 12000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a time will come when there would not be enough soil left to sustain life on earth‚ because the soil is a necessary growth medium for plants‚ a home for certain insects and animals‚ as well as a medium from which we get minerals‚ such as gold.

SOilIntroduction Soil plays a vital role in our ability to cultivate crops. Throughout human history‚ our relationship with the soil has affected our ability to cultivate crops and influenced the success of civilizations. This relationship between humans‚ the earth‚ and food sources affirms soil as the foundation of agriculture. Soil testing is necessary for knowledge of characteristic of the soil‚ quantity of fertilizer is needed so that fertilizers are used only as needed‚ not too less or too

What is Soil? Soil is the surface of the earth’s crust where plants have their roots and where many small animals make their home. It is also a result of the breakdown of rocks. Formation of Soil Soil is formed when rocks break down into very small particles by various processes such as weathering. There are two types of weathering: Physical Weathering and Chemical Weathering. Physical Weathering arises from the heating and cooling‚ the wetting and drying‚ and the freezing and
