Soils Of Sikkim

Chapter 4 SOILS OF SIKKIM Sikkim enjoys a wide range of climate, mapped, physiographic, geology and vegetation that curve the governance of unlike kinds of soils. 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 sloping (30 - 50%) Moderately steep sloping (15-30%) Valleys (15-30%) Rocky cliffs and precipitous huckster Glacier/Perpetual snow IDENTIFIED SOILS Soils occurring in different landforms argon studied in respect of their morphology, physical and chemical substance characteristics. In accordance with the physiographic sequence of the terrain features, 78 soil families were set 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 I nceptisols argon dominant (42.84%) followed by Entisols and Mollisols occupying 42.52% and 14.64% respectively. Sikkim has been divided into five broad physiographic units. The human relationship amid these physiographic units and their soils are established and discussed under the following heads.
