  • Black soils are mineral soils which have a black surface horizon, enriched with organic carbon that is at least 25 cm deep.
  • The black colour of these soils has been attributed by some scientists to the presence of a small proportion of titaniferous magnetite or even to iron and black constituents of the parent rock.
  • The black colour of this soil may even be derived from crystalline schists and basic gneisses such as in Tamil Nadu and parts of Andhra Pradesh.
