PPT-MAJOR SOIL POLLUTANTS WHAT IS SOIL?

Soil is the thin layer of organic and inorganic materials that covers the Earths rocky surface Soil is composed of particles of broken rock that have been altered by chemical and mechanical processes that include weathering and erosion Soil consists of major components . They generally are less than 2 inches thick and are massive Crusts are created by the breakdown of structural units by flowing water or raindrops or through freezethaw action Soil crusts are generally only a temporary condition Typically the soil im The soil should be neutral or slightly acidic with pH 65 to 70 having high organic content Very light sandy soils are not recommended owing to their poor moisture holding properties Climate Light Light is one of the most important climatic factors i Qinxue Wang, National Institute for Environmental Studies, 16-2 Onogawa, Tsukuba 305-8506, Japan, Tel: +81-29-850-2128; E mail: November 04 , 2013; January 28 Batkhishig(2014) Impact of Overgrazing Who are we?.
