Black soils are mineral soils which have a black surface horizon, enriched with organic carbon that is at least 25 cm deep. Two categories of black soils (1st and 2nd categories) are recognized. ... CEC in the black surface horizons ≥25 cmol/kg; and. A base saturation in the black surface horizons ≥50%.

Benefits of black soil-
