Morphology and physiochemical characteristics of three soils within the altitudinal range of 315 to 1490m under different vegetal cover of South Sikkim forests are discussed. The soils are acidic with fairly high content of organic matter and total nitrogen. Exchangeable calcium is maximum at the surface of all the soils and highest under mixed broad-leaved species. Humic acid content decreases down the profile. The properties of the three soils differ fairly widely and the difference can primarily be attributed to differences in physiograpby reflected through differences in vegetal cover and ultimately in the resultant soils. The three soils have been classified upto sub-group level according to Soil Taxonomy.- Suitability of Different Forest Species for Social Forestry Programme under Different Soil Conditions.

The growth of different forest species planted in road-sides and canal-banks has been correlated with the soil attributes in coastal zone of Midnapore district, West Bengal. Some of the sites having better nutritional status accelerates the growth of some selected species. On the basis of the results some species have been recommended for Social Forestry Programme under the said soil condition in a given climatic zone.- Suitability of Different forest Species for Social Forestry Programme Under Different Soil Conditions Part II-lateritic Soil

Height and girth increment of different forest tree species planted along road-sides, canal and river banks, wastelands and along railway tracks have been studied and correlated with soil attributes of lateritic soil zone of Midnapore district, West Bengal. Some of the sites having better nutritional status accelerated the growth of some selected species. On the basis of the results some species have been identified and recommended for planting in the lateritic belt to meet the demand for fuel wood and fodder.- Distribution of Organic Matter in Coppice Sal (Shorea robusta) in Relation to Soil Chemical Attributes

The above-ground biomass production in coppice sal in the lateritic region of West Bengal reveals that wood contributes the largest share of tbe total biomass followed by bark, branch, leaves, and twigs. Largest biomass production is observed in 8 years old coppice sal. The biomass production is highly correlated wilh total K2O aod P2O6 of the soil and the age, height and girth of the stands. The wood biomass is highly correlaled with total Ca and Mg of the soil.- Suitability of Different Forest Species for Social Forestry Programme under Different Soil Conditions Part I - Alluvial Soil

The growth of forest tree species planted along road sides, canal banks and railway tract has been correlated with the soil attributes in Alluvial soil zone of Midnapore district, West Bengal. Some of the sites having better nutritional status accelerate the growth of some selected species. On the basis of the results some quick growing species for Social Forestry programme and range of soil characteristics most suitable for optimum growth of plants in a given climatic condition have been recommended.- Soil Characteristics under Sal (Shorea robusta) in Tarai Region of the North-eastern Himalayas

The nature and properties of some sal (Shorea robusta) growing soils in the tarai region of North-eastern Himalayas were studied in order to evaluate the characteristic of the soils supporting the species It was found that since sal is growing well in this area, the characteristics and nature of the soils should be favourable for the growth and development of the species Ranges of Some Of the soil sutributes suitable for the optimum growth of the species under more or less similar climatic conditions were assessed.- Soil Characteristics Under Coppice Sal (Shorea robusta) in the Lateritic Region of West Bengal

The nature and properties of some coppice Sal (Shorea robusta) growing soils in the lateritic region of W. Bengal were studied in order to evaluate tbe characteristics of the soils supporting this species. Out of 31 sites, 23 sites bad GBH greater than the table values suggesting tbat these sites were very much favourable for optimum growth of Sal (coppice). Ranges of some of the soil attributes suitable for the optimum growth of the species under more or less similar climatic conditions were assessed.- Nature and Properties of Some Introouced Teak (Tectona grandis) Growing Soils of North-west Bengal

Nature and properties of some introduced teak (Tectona grandis) growing solis of Nort-west Bengal were studied in order to evaluate the characteristics of the solis supporting the species. It was found that since teak was growing well in the area, the characteristics and nature of the solis must be favourable for the growth and development of the species. Information from other good teak growing areas will help to generalise the range of the characteristics of the soils suitable for the species.- Variations in Properties of Soils Brought about by Termite Activity on Plants
