These soils have been mapped described, analyzed, characterized and classified under 5 colossal physiographic units. Table 4.1 Major physiographic units and overabundant soils found in Sikkim SL. Physiographic Units No 1 Summit and ridge (50%) Escarpments (>50%) Steeply angle (30 - 50%) Moderately steep sloping (15-30%) Valleys (15-30%) Rocky cliffs and astute huckster Glacier/Perpetual snow IDENTIFIED SOILS Soils occurring in different landforms argon studied in respect of their morphology, physical and chemical characteristics. In accordance with the physiographic sequence of the terrain features, 78 soil families were determine in Sikkim State and mapped into 69 mapping units. It revealed that soils of Sikkim belong to 3 orders, 7 suborders, 12 great groups and 26 subgroups. It is observed that Inc eptisols be dominant (42.84%) followed by Entisols and Mollisols occupying 42.52% and 14.64% respectively. Sikkim has been divided into five broad physiographic units.
