Soil: A natural body of mineral (non-living) and organic (living) material that forms on the surface of the earth, and is the medium for plant growth.. Forms over time from the decay of plants and organisms on the surface, and the break-down (weathering) of rocks, minerals, and sediments at, and beneath, the surface.. 1 Conjugated unsaturated systems have a porbital on a carbon adjacent to a double bondlThe porbital may be empty (a carbocationThe porbital may hold one electron (a radical)lThe p orbital may hold two CLORPT for short. Soils differ from one part of the world to another, even from one part of a backyard to another. . They differ because of where and how they formed. And over time, five major factors control how a soil forms. These factors are . Soils. We know more about the movement of celestial bodies than about the soil underfoot. . - Leonardo da Vinci.

Soils support the growth of higher plants by providing a medium for plant roots and supplying nutrient elements that are essential to the entire plant.. Soil properties are the principal factor controlling the fate of water in the hydrologic system. Water loss, utilization, contamination and purification are all affected by the soil..
