Terai region of sub–Himalayan West Bengal is a land of tea and plantation forests. These century old plantations are not only the socioeconomic backbone of the region but also the determinant for the environment and weather conditions. This research initiative was to determine the physico-chemical status of soil in the plantations of this region. Parameters like soil texture, bulk density, moisture content,pH, organic carbon, organic matter, total nitrogen, available phosphorus, potassium, sulphur in soil and micronutrient analysis were conducted in top and sub soil of varied plantations like Camellia sinensis, Ficus elastica, Bambusa vulgaris, Shorearobusta, Lagerstroemia speciosa, mixed forest, fallow dry land and fallow wet land areas respectively. Soil texture of the study area was witnessed to be predominantly sandy loam with bulk density of the soil ranging from 0.485 gm/cm3 to 1.241 gm/cm3. Good moisture content due to considerable rainfall; acidic pH; high organic carbon, organic matter; moderate nitrogen, phosphorus and potassium with low sulphur content were the overall soil nutritional status of the region. This paper highlights the pattern of nutritional demand and the present status of soil nutrition in terai land of sub–Himalayan West Bengal, providing insights with respect to ecologically sustainable management of soil quality.
