Soils
... Although soils can be grouped together in various categories according to characteristics, no two soils are truly identical. This is partly a function of the fact that no two parent materials (e.g. rocks) are truly identical. Also, the amounts and types of organic material contained in soils differ ...

Soil fertility and crop production
... Crop production is based largely on soils. For large-scale and low-cost crop production, there is no substitute for natural soils as a substrate for crops in the foreseeable future. Soils are the uppermost part of the earth’s crust, formed mainly by the weathering of rocks, formation of humus and by ...
