Alfisols are base-rich mineral soils of subhumid and humid regions. Generally, the subsoil contains significant accumulation of illuviated silicate clays. The subsurface horizons are rich in exchangeable cations with high base saturation. These soils are developed from different type of parent material and at varied geomorphic position. Many of them are formed on pediments and are thus stony and gravelly. The soil is suitable for growing a wide variety of crops.
