Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Field experiments at three locations, namely Bolampatti, Pethikuttai and Coimbatore (Coimbatore Forest Division, Tamil Nadu) having different rainfall pattern and soils were conducted in 1985-86. Coir pith mulch was used on heavier soils of Bolampatti and Coimbatore, while gravel mulch was used on medium soil of Pethikuttai. Height of A. planifrons (113%), A. nilotica (96%), P. pterocarpum (85%), A. indica (60%) and E. camaldulensis (57%) increased due to coir pith mulch treatment. Response to mulch treatment was not so marked in case of A. leucophloea (27%) and T. indica (13%). A. lebeek, E. cuminii and P. pinnata did not respond to treatment. At Pethikuttai, use of gravel mulch increased height of E. camaldulensis (53%), A. indica (59%) C. pentendra (47%), A. leucophloea (68%) and A. nilotica (96%), A. planifrons (51%), P. pterocarpum (91%) A. lebbeck (122%). Growth of E. cuminii, C. equisetifolia, P. pinnata and T. indica was not significant due to mulch. At Coimbalore, where additional water was also given during severe moisture stress, plant height of C. equisetifolia increased from 115 to 147 cm E. camaldulensis from 102 to 120 cm in 6 months after planting. T. indica did not respond to mulch application at this site. Use of coir pith mulch maintained significantly higher moisture regime at all the locations throughout the growth period. Coir pith mulch reduced the surface soil temperature by 3 to 5°C at Coimbatore.

Abstract

Study was Initiated to evaluate the effects of removal of Chir pine needles from the forest floor of 57 years old Pinus roxburghii plantation at the Champion Block. F.R I, Dehra Dun. Data collected for the first year reveal that maximum (83%) needle fall did occur during pre-monsoon period followed by monsoon months (12%), dry months (4%) and post monsoon months (1%). The moisture content in the needles, recorded was 5.5% for pre-monsoon needle fall, 6.0% for monsoon fall, 27.3% for dry period and 39.9% for post monsoon fall. Approximately 10.79% metric ton/ha of needles were shed during the year. This litter fall contained about 113 kg/ha of N., 15 kg/ha of P, 35 kg/ha of K, 65 Kr/ha of Ca, 22 kg/ha of Mg and 338 kg of ash/ha. No significant change in soil properties has been noticed at present due to removal of needles. The observation in this regard is continuing.

Abstract

The nature and properties of the soils supporting Cryptomeria japonica in Darjeelling Himalayan Region were studied. The soils are acidic and contain high organic matter. The growth parameters are inversely related to the p^H and organic matter of the soils while height of plants and basal area of tbe species are positively correlated with C.E.C., exch. Ca⁺²,Mg⁺², K⁺ and available phosphorus. Total nitrogen contents of the soils are correlated positively with G.B.H. and basal area but negatively with the heights of the plants. Ranges of some of the attributes suitable for the growth of the species under more or less similar climatic conditions are assessed.

Abstract

A vailable P has a low status in the soils or Pali range (Shahdol) while status or available K is medium to high. Available P and K have a positive correlation with all the factors like clay, pH, CaCO₃, organic matter and catipn exchange capacity in the soil developed over Deccan trap. While it has a negative correlation with all the above factors except organic over in the soil developed over lametas (Calcareous). In the soils developed over Gondwans sand stone, available P and K show mixed rotationship. It shows negative correlations with some factors like clay, pH, calcium carbonate etc. and positive correlation with others like organic matter and in some profiles clay C E.C etc. Hence there is a need to study to investigate responses to P application for enhancing forest productivity.
