PPT-SOIL ANALYSIS What is Soil?

The top layer of Earths crust where most plants grow It contains minerals decaying organisms water and air It is divided into horizons which are layers parallel to the Earths surface in which . 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 texturecourtesyNASA: (Getandsample)soilhorizonsmallthesprayLetthebetweenthemoisturethroughout.OncetheStepStep(TestIf the soil: handswhenrubbedandStep themediumribbon 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 Uppermost layer of earth’s crust that supports plants, animals and microbes.
