Soil is one of humankind's most important resources, providing for the growth of arable crops, grassland and trees, which give us food, fibre, and timber. As part of the natural environment, soil supports the plant growth needed for the cycling of gases, provides a habitat for a wide range of organisms, buffers the flow of water and solutes between the

Metalloids, Soil Chemistry and the Environment
2010This chapter reviews physical chemical properties, origin and use ofmetalloids and their relevance in the environment. The elements boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are considered metalloids.

The soiled environment: bubble, bubble, soil in trouble
Medical Journal of Australia, 2002There are many contaminated soil sites in Australia. Contamination may be from human activities (eg, smelters, industrial waste dumps, old gasworks) or from naturally occurring sources (eg, surface mineralisation). Concentrations of contaminants may vary markedly across a site. Their distribution may be localised or quite extensive. Common contaminants

Soils in Harmony with the Environment
2016Soil, like air and water, is critical to terrestrial life on Earth. Soil is out of sight and easy to overlook, yet intrinsically beautiful. Earth has a diversity of landscapes from Antarctic deserts to tropical rainforests, each with a complex variety of soils.

Reviews in Mineralogy and Geochemistry, 2001
“ The limited occurrence of these minerals has resulted in a scant knowledge about their properties in the soils. ” Zelazny and Calhoun (1977) As pointed out by the above authors, the occurrence of natural zeolites in soils is rare and not well known, and only about 75 papers have been published describing the occurrence of zeolites in soils.

Extreme environments limit life. Extreme environments are generally limited by moisture and temperature and include both hot deserts such as the Sahara and cold deserts such as the Dry Valleys of Antarctica. Geothermal activity creates extreme environments of heat and acidity or alkalinity that challenges survival for all but a few specially adapted ...

Manipulation of Soil Environment to Create Suppressiveness in Soils
1989Recognition of the occurence of soils that suppress diseases due to soil-borne plant pathogens led to the basic concept of soil suppressiveness or as we proposed in french “soil receptivity to diseases” (Alabouvette et al 1982; Corman et al 1986; Louvet in this book).

Abstract Within any landscape there is an incredible range of soil types resulting from variation in soil-forming factors, namely parent material, climate, topography, time, and biota. This chapter introduces the soil-forming factors and how they influence the physical and chemical properties of soils.
