Abstract

A study on soil water retention pattern under Chir (Pinus roxburghii), Khair (Acacia catechu), Eucalyptus (Eucalyptus hybrid) plantation and barren land was conducted in Mussoorie Forest Division (UK). Multivariate test showed that the mean soil retention changes across the different soil depth. The maximum amount of water was retained by the soils under Khair (356.90 to 879.40 k lit/ha) followed by Chir (286.73 to 913.13 k lit/ha), Eucalyptus (212.50 to 932.50 k lit/ha) and the least under barren land (116.27 to 824.03 k lit/ ha) during the different months of the year. Good amount of water can be retained by the soils under plantation even in the drier months of April (255.20 to 393.27 k lit/ha) to June (21.50 to 356.90 k lit/ha) as compared to barren land (116.27 to 221.0 k lit/ha). Even in the driest month of May, surface layer can hold 148.89 % and over all entire profile by 217.73 % more water under plantations as compared to barren land. In drier months, lower layers had higher retention as compared to upper layers. From July to September, soil profile retained maximum water because entire profile gets recharged due to rainfall.

Abstract

Soil characteristics in relation to Forest vegetation and parent material in Kempty range of Mussoorie Forest Division, Uttarakhand have been studied. The results show that geologically, the rocks of the study area are of pre-cambrian to early paleozoic in age with recent and subrecent deposits. The organic matter and available nitrogen contents in the surface horizons increased with increase in altitude. The increase in the clay content of B horizon may be due to in-situ weathering of minerals. From the clay content of different horizons, it is quite evident that movement of clay from A to B horizon has taken place in all the profiles. Due to clay illuviation and greater thickness of B horizon, soils from Sainj, Kempty and Mailgarh blocks having Pinus roxburghii, Quercus leucotrichophora and Dalbergia sissoo vegetation, respectively, appeared to be more developed than those from Kheragarh and Gandiyala blocks (Miscellaneous and barren land). Statistical analysis showed that source of variations in different soil characteristics are significant for Clay, pH, CEC, Ex. Na, Available N and WHC for replications It has been observed that Q. leucotrichophora and P. roxburghii forests occur in the soils of Mollisols order on limestone, dolomite, shale, slate and quartzite (Kempty and Sainj blocks) whereas presence of phyllite (Mailgarh and Kheragarh blocks) shale, sandstone, quartzite etc. resulted in Ultisols order. The barren land soil of Gandiyala block belonged to Mollisols order. Findings of the study will be helpful to formulate the strategies for sustainable management of the natural forests and to work out potential productivity of soil and forest etc. for the overall afforestation of such lands and to create deeper understanding of natural stands ensuring ecological and economic benefits reaching the rural masses.

Abstract

A study was conducted in Saini Majra (Haryana) under agroforestry system and at nearby open area to investigate the light intensity pattern under both the sites. Open area received 96.42% higher light intensity as compared to agroforestry system because there were no trees on the field. Maximum light intensity was recorded during mid-day (1210 to 1235 hrs) under both the sites. It is evident from the study that Poplar trees planted in agroforestry system can absorb or reflect up to 51.76% solar radiation before reaching to the ground even at a leafless stage.

Abstract

Global warming and emission of CO₂ are of world wide concern because these are creating environmental imbalance and are a long term threat to the well being of all life on earth. Soil is a major sink of carbon. 9815.95 million tonnes of Soil Organic Carbon (SOC) store was estimated in total forest soils (as per 1994 forest stands) under 19 species spread over 27 States and Union territories in India. Spruce forest soil has maximum SOC store (386.0 t/ha) while Khair has minimum (51.93 t/ha). In India , miscellaneous forests are spread over an area of 40.7316 million ha , and their soils have maximum SOC store (6469.80 million tonnes) while in Hollong forest with an area of 0.0068 million ha , soils have the least SOC store (0.82 million million tonnes). Among the Indian States , Arunachal Pradesh has maximum SOC store (1702.08 million tonnes) while Dadra&Nagar Haveli has minimum (2.42 million tonnes) SOC store. Arunachal Pradesh ranks first in India having 248.11 t/ha SOC store in the soils of the State. Soil conservation practices should be strengthened to conserve these natural resources so that carbon store may not deplete especially from hilly terrain.

Abstract

Factor analysis of soil nutrient distribution pattern under Chir, Teak, Eucalyptus, Shish am and Khair, in Mussoorie Forest Division (U.P.) was studied. It was done to identify underlying factors that are responsible for correlation among nutrients under five plantations. Eigen values for the first four factors were > 0.90 and combined accounted for 77 percent of total variation in the soil supporting the five plantations. The four factor model explained > 90 percent of the variance in total phosphorus; 85 percent of the variance in organic matter and available nitrogen; and > 70 percent of the variance in total nitrogen, total potassium, and total sodium, available potassium and available phosphorus. However the four factor model explained only 62 percent of the variance in available potassium and 66 percent of the variance in total calcium. The four extracted factors are aggrading factor (36.6 percent), Sodium factor (16.16 percent), Phosphorus factor (12.67 percent) and total phosphorus factor (11.92 percent) obtain through varimax orthogonal factor analysis.

Abstract

Soil nutrient changes were studied under 5, 10, 15 and 20 years old Eucalyptus monocultures, in comparison to natural sal forest. Soil nutrient depletion under 10 and 15 years old monocultures were higher than 5 and 20 years old monocultures, in comparison to natural sal. Soil profile distribution of attribtttes showed gain in clay content and available P and loss in total K and P in all monocultures as compared to natural sal. The soil under 5 year and 20 year monocultures were less depleted because of faster mineralisation of residual organic matter in 5 years old monoculture and a gradation of soil nutrients as the monoculture aged as in 20 years old monoculture.

Abstract

The present study reveals that selection system soil has more infiltration capacity than that under clearfelling system. Selection system provides longer opportunities for infiltration in comparison to clearfelled system due to more organic matter (6.72%) which increased porosity (56.7%) and water holding capacity (71.3%) of the forest soil. Clearfelling system provides less organic matter (4.62%) to the soil hence porosity (41.2%) and water bolding capacity (46.4%) of tree-less soils are comparatively lower.

Abstract

A study was conducted in Picea smithiana (Spruce) and Abies pindrow (Silver fir) forests managed under selection, shelterwood and clearfelled management systems in Kotgarh Forest Division (H.P.) to study the phosphorus behaviour in soils with challge in these systems. Level of soil phosphorus in different sites within the management systems, specific effects of management systems and site conditions. correlation between phosphorus level and soil depth in all conditions of the study, intercorrdation between total and available phospborus were worked out. Soils under selection system were well supplied with phosphorus followed by shelrerwoott and clearfelled systms. In many cases phosphorus level was indfpendent of soil depths as well as total and available forms were also mutually indeptendent of each other. The immobility of the element, biologically mediated uptake, soil pH etc. seemed to have brought about the pattern observed in this study The selection management and good site conditions have maintained better pbosphorus supply. Overall observations clearly indicate low soil phospborus supply in these forests.

Abstract

Soil organic carbon was estimated in four land uses viz. forests, plantations, agroforestry and horticulture in Haridwar district. Over all 425 soil samples were collected from different land uses at various locations. Soil organic carbon, bulk density and coarse fragments were estimated in collected samples and SOC pool was calculated by using the equation as suggested by IPCC Good Practice Guidance for LULUCF. Maximum SOC pool (73.63 t/ha) was estimated under sal forest followed by miscellaneous forest (56.48 t/ha). Under horticulture land use, SOC pool was higher (58.66 t/ha) in the soils under litchi orchard as compared to Mango orchard (40.62 t/ha) and Guava (29.46 t/ha) orchard. Under block plantation, maximum SOC pool was estimated in the soils under teak (52.50 t/ha) followed by eucalyptus (39.06 t/ha), poplar (30.45 t/ha) and the least was under shisham (28.12 t/ha). Under agroforestry model, poplar - sugarcane showed higher SOC pool (25.78 t/ha) as compared to poplar - wheat (22.93 t/ha). On an average, Haridwar's forests have 65.05 t/ha SOC pool while horticultural land use have 42.91 t/ha, plantation have 37.53 t/ha and agro-forestry have 24.35 t/ha. Soils under forests stand show higher carbon pool than other land uses. Average SOC pool under forests was 65.05 t/ha, therefore, Haridwar district has 4.09 million ton of SOC pool under forests.

Abstract

Soil samples for the estimation of organic carbon store were collected from the entire catchment area starting from Rajban to origin of Giri and all the land uses were covered to estimate soil organic carbon. Soil organic carbon store in Giri catchment was estimated (up to the depth of 30 cm), and observed that maximum SOC store (93.47 t ha^-1 ) was in the soils under Kail + Silver fir and Spruce forests and Kail + Quercus forests followed by Deodar forests (82.14 t ha^-1). Soil organic carbon store under miscellaneous forests (57.66 t ha^-1) and chir forests (57.33 t ha^-1 ) was similar and the least SOC store was under sal forests (47.29 t/ha). Under agriculture land use, in cropping srstem soil organic store was 53.62 t ha^-1 while under orchards it was 53.96 t ha^-1. Altitude wise maxImum soil organic carbon pool was in the soils located above the altitude of 2500 m (91.37 t ha^-1 ) followed by 2000-2500 m ( 88.68 t ha^-1). The least SOC store was in the soils located below 1000 m (54.34 t ha^-1). Girl catchment has 8,165,593.15 tones (8.16 million tons) soil organic carbon store in the forest area and under agriculture land use soil organic carbon store is 3,167,521.58 tones (3.16 million tons).

Abstract

Estimation of SOC pool under different vegetation covers was conducted in Almora district of Uttarakhand state in two land uses viz. forests where soil organic carbon pool was estimated in Deodar (Cedrus deodara), Quercus (Quercus leucotrichophora), Sal (Shorea robusta), Chir (Pinus roxburghii) and miscellaneous forests and under horticulture land use where SOC pool was estimated in apple orchards. Maximum SOC pool was observed in the soils under Deodar forest (114.36 t ha^-1) followed by Quercus (91.77 t ha^-1), Sal (61.51 t ha^-1), Chir (54. 18 t ha^-1) and the least was under miscellaneous (24.68 t ha^-1). Subset for α= 0.05 indicate that Deodar stands separately (a), Quercus stand separately (b) Sal and Chir were together (c) and miscellaneous forest was also in separate SOC pool (d). SOC pool in soils under apple orchards was 61.99 t ha^-1 . On an average, forests in Almora district have 73.76 t ha^-1 SOC pool in the soils. All the forests of the districts have 1,74,20,939.95 tones (17.42 million tons) SOC store in the soils. In the district 1.26 million tons SOC pool was estimated in the soils under horticulture land use system.

Abstract

Soil organic carbon (SOC) is a major component of global carbon sinks and forests being one of the most important ecosystems for storing SOC. A database of SOC estimates along with other attribute information for different forest types of India were compiled from various literature sources and normalized for 1990 using modeling approach. Different thematic maps in digital format were prepared and harmonized using standard geospatial reference. The database was linked to thematic maps and used to estimate SOC densities and stock for three depth classes (0-25, 0-50 and 0-100 cm) in geographical information system. The mean soil organic carbon density estimates for top 30 cm ranged from 22.42 t/ha in sub-tropical dry evergreen forest to 100.33 t/ha in Himalayan moist temperate forest and similar trend was observed for top 0-50 and 0-100 cm as well. Soil organic carbon stock estimates for top 30 cm ranged from 1.89 Tg C in Himalayan dry temperate to 1406.68 Tg C in tropical moist deciduous forest and comparable trend was observed for top 0-50 and 0-100 cm. The total soil organic C pools in Indian forests have been estimated as 3.72, 5.25 and 7.66 Pg C in top 0-25, 0-50 and 0-100 cm soil depth respectively (1 Pg = 1000 Tg). The present database may form inputs in models to study carbon flux and help in prioritizing areas for carbon sequestration in Indian forests.

Abstract

A study was undertaken in western region Haryana comprising Bhiwani, Fatehabad, Hisar, Jind and Sirsa districts to estimate soil organic carbon stock under different land uses viz. forests, block plantations, horticulture, agroforestry and agriculture. Maximum organic carbon stock was found in the soils under forests (40.26 Mg ha^-1). It was followed by plantation (33.27 Mg ha^-1), horticulture (25.69 Mg ha^-1), agroforestry (21.98 Mg ha^-1) and the least SOC stock was under agriculture (18.10 Mg ha^-1). Total soil organic carbon stock under forests was 1.22 million tons, out of these, Jind district has the maximum SOC stock (3, 17, 898.62 Mg). Least SOC stock was in Fatehabad district (1, 16, 086.27 Mg). Total SOC stocks under horticulture was 5, 23, 476.12 Mg, out of this, Sirsa district has 2, 64, 919.95 Mg and the least SOC stock was in Jind district (36,537.21 Mg). Soil organic carbon stock in Abubshehar Wildlife Sanctuary was 47, 7578.17 Mg and in Bir Bara Van Conservation Reserve was 19,490.85 Mg.

Abstract

India has stabilized its forest and tree cover which is about 24.01 per cent of its total geographical area. Forests store significant amounts of carbon in its biomass, litter, dead woods and soil; and it has a major role in climate change adaptation and mitigation. Soil carbon is the largest terrestrial carbon pool and it holds a very important role in the carbon cycle. Soil samples were collected from all major forest types in different parts of the country as well as from adjoining non-forest areas for estimating the loss of soil organic carbon due to land conversion. The results of this study indicated that maximum soil organic carbon stock was under tropical moist deciduous forests (1665.65 million tonnes) followed by tropical dry deciduous forests (1572.38 million tonnes) and least under Himalayan dry temperate forests (3.85 million tonnes). The total soil organic carbon stocks i.e., 4327.36 million tonnes and 4680.25 million tonnes were estimated under the forests in the year 1995 and 2007 respectively. The estimate showed that due to increase in forest cover during the assessment period, soil in Indian forests acted as a net sink of 352.89 million tonnes of soil organic carbon. The maximum increase in soil organic carbon stock during this period was under tropical moist deciduous forests (125.91 million tonnes) and the least increase was under Himalayan dry temperate forests (0.23 million tonnes).

Abstract

A study was conducted to assess litter fall, nutrient return and soil fertility under Grewia optiva which is an important agroforestry species in Himachal Pradesh. The average annual litter fall of G. optiva has been recorded as 170.25g/m²/yr. The annual leaf litter recorded (79.56 g/m² /yr which was 46.73 per cent of total litter) was maximum followed by miscellaneous litter (43.31 g/m² /yr which was 25.44 per cent of total litter fall), reproductive litter (26.05 g/m² /yr which was 15.30 per cent of total litter fall), twigs (17.83 g/m² /yr which was 10.47 per cent of total litter fall) and the 2 least was from bark component (3.50 g/m² /yr which was 2.06 per cent of total litter fall). Nitrogen in leaf litter, twigs, reproductive litter, miscellaneous litter and bark was 2.23, 1.21, 0.91, 1.01 and 0.95 per cent respectively while phosphorus concentration was maximum (0.139 %) in leaf litter followed by twigs (0.11 %), reproductive litter (0.11 %), bark (0.11 %) and the least was in miscellaneous litter (0.08 %). Potassium concentration was varied from 1.13 per cent in miscellaneous litter to 2.03 per cent in leaf litter. Calcium concentration varied from 1.75 per cent in reproductive litter to 3.12 per cent in bark while magnesium concentration varied from 0.22 per cent in miscellaneous litter to 0.48 per cent in twigs. The trend of nutrient return was in order of Ca (4.26 g/m² /yr) > K (2.71 g/m² /yr) > N (2.48 g/m² /yr) >  Mg (0.72 g/m² /yr) > P (0.18 g/m² /yr). Monthly leaf litter and their respective nutrient concentration for nitrogen, phosphorus, calcium and magnesium were significantly related. Soils under G. optiva were well enriched in organic matter and available nitrogen, phosphorus and exchangeable potassium.
