In India, Histosols are the soil order that has a negligible area. Histosol is soil consisting primarily of organic materials.
Organic soil material has an organic carbon content of 12 - 18% or more depending on the clay content of the soil. Histosols have very low bulk density and are poorly drained because the organic matter holds water very well. Histosols are also called Organosols.
