Soil is a creation of nature and consists mostly of minerals (45%) and very little organic matter (about 5%). It provides a habitat to man and animals, and supports plant life.
Soil is the unconsolidated mineral material on the immediate surface of the earth that serves as a medium for plant growth.
The factors controlling the rate of soil formation and the final product are (a) parent material, (b) climate, (c) biota, (d) topography, and (e) time. These five factors interact to produce all varieties of natural soils. Soil differs from the material from which it is formed in many physical, chemical, biological and morphological properties and characteristics.
Mankind has indirectly or directly created soils. When natural soils are not suitable, people extensively modify soils to suit their needs.
Soil usually has two or more horizontal layers, which can be seen from the soil profile in a vertical crosssection. The horizontal layers of the soil, with their own texture and color, are called soil horizons. The thickness and composition of horizons distinguish one soil from another; each horizon has a distinct identity. There are three almost distinct horizons namely, the plow layer, the leached layer and the accumulation layer.
Mature soil may be described in terms of the following four soil horizons: (i) A horizon is the uppermost layer, containing organic matter, though most soluble chemicals have been leached from it. (ii) B horizon is strongly leached with little or no organic matter. A and B together are often called the topsoil. (iii) C horizon is the subsoil, a layer of the weathered and shattered rock. (iv) D horizon is the bedrock. The main types of soil are pedalfers, pedocals and laterites or latosols.
Soils may also be classified in terms of texture. hams, with roughly equal proportions of sand, silt and clay, together with humus, are among the richest agricultural soils. Wearing away of the soil is a primary cause of concern in agriculture.
