Abstract

Four pot culture experiments were carried out to determine the response of N, P and K by Eucalyptus tereticornis varieties FRI-4 and FRI-5 grown on sandy loam New Forest Soils, Leaf number, average leaf area, total leaf area, fresh biomass and dry biomass of both the varieties responded to N application whereas variety FRI-4 responded to N+K application and variety FRI-5 to N+P application. These growth parameters were also highly correlated with the Fertilizer Use Efficiency (FUE) (mg dry biomass/mg N, P or K). Interestingly FUE of varieties FRI-4 and 5 were inherited from their mothers E. camaldulensis and E. tereticornis respectively. Further, these parameters were directly related to the relative chlorophyll content of leaves; a determination of light transmission through leaf at photographic infrared band; measured using "Agrophotometer".

Abstract

Greenhouse study was carried out to determine fertilizer use efficiency of trees species with regard to N, P and K nutrients. Eucalyptus cumaldulensis. E. citriodora and Acacia nilotica responded to the application of N, P and K whereas Acacia catechu. Eucalyptus, grandis E. tereticornis var FRI-5 and Prosopis juliflora responded to only N and P application and Albizia lebbeck. Leucaena leucocephala and E. tereticornis var FRI-4 responded to N and K only.

Abstract

Greenhouse experiments were carried out to see the response of N, P and K by A. nilotica seedlings grown on sandy loam New Forest soils. Treatments consisted of 0,50, 100, 150 and 200 ppm N (100 ppm P₂,O₅, and 50 ppm K O as basal dose); 0,50,100 and 150 ppm P₂,O₅, (100 ppm N and 50 ppm K₂O as basal dose); 0, 25, 50 and 75 ppm K₂O (100 ppm each of N and P₂O₅, as basal dose) and factorial combinations of 0 and 100 ppm N, 0 and 100 ppm P₂O₅, and 0 and 50 ppm K₂O. A. nilotica seedlings responded to N applied alone or in combination with P and K. Application of P and K applied alone or in combination decreased the growth, yield and fertilizer use efficiency in Ihe absence of N. The best treatment of 100 ppm N, 100 ppm P₂O₅, and 25 ppm K₂O was observed.

Abstract

A detailed phytosociological analysis of woody species of Chakrata forest at twelve different sites supporting seven tree species viz., Cedrus deodara, Pinus roxburghii, Picea smithlana, Pinus wollichiona, Quercus florihunda, Q. semicarpifolia and Abies pindrow was carried out. Their total basal cover varied between 1455 and 5672 cm² 100 m^-2 and total density from 0.7 to 3.7 trees 100 m^-2. The distribution pattern was random for most of the species. The species diversity was greatest in Pinus wallichlana forests followed by Quercus floribunda forests. However, the values of concentration of dominance, exhibited inverse relationship with the species diversity.

Abstract

Reducing emissions from deforestation and degradation (REDD+) in Non-Annex-I countries is of central importance in efforts to combat climate change, because carbon management in forests will probably be the single most important st agenda of the first half of the 21^st century in the context of the greenhouse effect and mitigation of global climatic changes. In this context we tried to know the position of Carbon stock in India from 1880 onwards by compiling the published literature, besides that the C stocks for the year 2003, 2005 and 2007 were also estimated on the basis of GS data published by Forest Survey of India. Carbon stocks in Indian forests from 1880 showed a marked decrease from 7940 Mt in 1880 to 3426 Mt in 1980 which have reduced to 3325.30 in 2003 to 3161.71 Mt in 2007. The carbon stock in India's forest biomass decreases continuously despite slight increase in forest cover of the country.

Abstract

Reducing emissions from deforestation and degradation, along with conservation and sustainable management of forests, known as REDD+ is recognized as an innovative climate mitigation option for incentivizing local communities. India has contributed a lot to this process in international negotiations. However now, the mechanism needs to be implemented at national, state and local levels. Country should be ready with national strategy and action plan and like various other countries pilot projects could be started in different parts of the country to draw lessons for full-fledged implementation of REDD+. Deforestation is not much of the problem in the country. So focused efforts should be made for addressing the drivers of degradation and for conservation and sustainable management of forests in the country. Enough potential exists for enhancement of forest carbon stocks in various kinds of forests, in trees outside forests in both urban and rural landscapes, and in coastal areas. This needs to be harnessed with the help of a huge network of JFM communities in the country. India has developed tremendous capabilities in use of remote sensing, which can be utilized for development of reference levels and carrying out measurement, reporting and verification of carbon stocks. However, capacity needs to be built at state and community levels for mainstreaming REDD+ at all levels in the country.

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).
