“…Among root components, fine roots had the maximum value (0.45-0.49% N; 0.06-0.07% P; 0.25-0.28% K) followed by lateral roots and stump root. These results are in general agreement with those obtained from different aged Eucalyptus globulus plantations (George and Varghese 1990) and Populus deltoides plantations (Lodhiyal et al 1995;Singh 1998). The leaf component of plant is metabolically most active and accumulates maximum amount of nutrients.…”

“…The amounts of nutrients transferred to the plantation floor via litter fall were calculated. The turnover rate (k) for each element on the plantation floor was calculated as: k = A/(A + F) where, A is the amount of nutrient added to the plantation floor by litter fall and F is the nutrient content of the lowest value of floor litter in the annual cycle (Lodhiyal et al 1995). Turnover time (t) was calculated as the reciprocal of the turnover rate (k).…”

“…Bernier (1984) also suggested that poplars were efficient in the cycling of nutrients and that a large portion of nutrients utilized for annual growth was periodically involved in cycling. Lodhiyal et al (1995) compared poplar with Eucalyptus and found that there was a higher proportion of nutrient retranslocation in poplar as compared to that of the Eucalyptus plantations. From the standpoint of sustainability, studies on aspects of nutrient use by species harvested in short cycles are important for the tree based intercropping system.…”

Nutrient concentrations in plant and soil and their rates of cycling in poplar (Populus deltoides)-based agroforestry systems were studied at Pusa, Bihar, India. The nutrient concentrations in the standing biomass of the crop were more than those in tree, whereas the nutrient contents showed the reverse trend. Soil, litter and vegetation accounted for 80.3-99.5, 0.1-5.0 and 0.4-14.7%, respectively, of the total nutrients in the system. Considerable reduction (40-54%) in concentration of nutrients in leaves occurred during senescence. The uptake of nutrients by vegetation, and also by different components with and without adjustment for internal recycling, were calculated separately. Annual transfer of litter nutrient to the soil by vegetation was 37.3-146.2 N, 5.6-17.9 P and 25.0-66.3 K kg ha À1 year À1 in young (3-year-old) and mature (9-year-old) plantations. Turnover rate and time for different nutrients ranged between 0.86-0.99 year À1 and 1.01-1.16 years, respectively. Compartmental models for nutrient dynamics have been developed to represent the distribution of nutrient contents and net annual fluxes within the system. This study shows that the poplar-based agroforestry system can be sustainable in terms of soil nutrient status.

The purpose of this study was to characterize the carbon, nitrogen, phosphorus and potassium in the Barnowpara Sanctuary, Raipur district, Chhattisgarh, India through the use of satellite remote sensing and GIS The total storage of nutrients in vegetation (OS+US+GS) varied from 105.1 to 560.69 kg ha -1 in N, 4.09 kg ha -1 to 49.59 kg ha -1 in P, 24.59 kg ha -1 to 255.58 kg ha -1 for K and 7310 to 4836 kg ha -1 for C in different forest types. They were highest in Dense mixed forest and lowest in Degraded mixed forest. The study also showed that NDVI and carbon storage was strongly correlated to Shannon Index and species richness thus it indicates that the diversity of forest type play a vital role in carbon accumulation. The study also developed reliable regression model for the estimation of LAI, biomass, NPP, C & N storage in dry tropical forests by using NDVI and different vegetation indices, which can be derived from fine resolution satellite data. The study shows that dry tropical forests of Central India are quite immature and not in standing state and have strong potential for carbon sequestration. Both quantitative and qualitative information derived in the study helped in evolving key strategies for maintaining existing C pools and also improving the C sequestration in different forest types. The study explores the scope and potential of dry tropical forests for improving C sequestration and mitigating the global warming and climatic change.

“…The concentration of nutrients within the ecosystem usually depends upon a functional balance in their intra system cycling (Lodhiyal et al 1995, Rawat & Singh 1988. Elements taken up by trees become available again for uptake and growth through litter fall, canopy leaching and retranslocation.…”

A 72-year-old mixed oak/beech stand has been studied on the element (N, P, K, Ca and Mg) content in its woody biomass, in the wood increment and in the litter fall. Crown leaching and nutrient uptake have been calculated respectively according to Ulrich (1983) and to Cole & Rapp (1981). Eight oaks and six beeches have been sampled, regression equations between the tree element content and the stem volume have been calculated in order to scale up from the tree to the stand level.The annual amount of elements taken up is 70 kg N, 4,9 kg P, 69,3 kg K, 43 kg Ca and 6,1 kg Mg per ha. For K, Ca and Mg a large part of the nutrient uptake is due to crown leaching. The amount of Nand P in the litter fall constituted the largest part of the uptake of Nand P. For the elements K, Ca and Mg, crown leaching is very important in the nutrient cycling: crown leaching amounts respectively 63%, 21% and 43% of the annual return of these elements from the canopy to the forest floor.
