Alluvial soils (khadar and bhangar) are azonal soils. They form in transported and recently deposited materials. Azonal soils have a profile determined predominantly by factors other than local climate and vegetation.

Lateritic soils are the most weathered and infertile of all soil types. Due to intensive leaching and low base-exchange capacity, typical lateritic soils are generally infertile and of little value for crop production (Geography of India by Smita Sengupta, p 63).

Edaphic is a nature related to soil. Edaphic qualities may characterize the soil itself, including drainage, texture, or chemical properties such as pH. Edaphic may also characterize organisms, such as plant communities, where it specifies their relationships with soil.

Leaching refers to the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Laterite soils are formed soils under conditions of high temperature and heavy rainfall with alternate wet and dry periods. They are leached and are, thus, less fertile.
