Soil Horizon is classified into three categories − Horizon A, Horizon B, and Horizon C; collectively known as Soil Profile (i.e. the arrangement of soil layers
Horizon A’ is the topmost zone, where organic materials stored with the minerals, nutrients, and water, necessary for the growth of the plants.
‘Horizon B’ is the transition zone between the ‘horizon A’ and ‘horizon C’, and hence, it contains matter derived from ‘horizon A’ as well as from ‘horizon C’.
‘Horizon C’ is composed of loose parent material and hence, it is the layer of first stage of the soil formation process and eventually forms the above discussed two layers.
Classification of Soil
Soils were classified on the basis of their inherent characteristics and external features including texture, color, slope of land, and moisture content in the soil.
Soil Survey of India, established in 1956, made comprehensive study of soils.
Hey dude..........
Soil is very important and a valuable resource for every human being. Soil is the mixture of rock debris and organic materials, which develop on the earth's surface. The major factors that determine soils' characteristics are parent material, climate, relief, vegetation, time, and some other life-forms.
