“…The nutrient returned to the soil through senescent leaves was in the order of N>K>P. Pattern of nutrient concentration in senescent leaves varied according to the species. Similar to our results, Singh et al (1989) and Lodhiyal & Lodhiyal (1997) reported the returned nutrient content by leaf litter in the order of N>K>P in Populus deltoides plantations in moist plain area in the north of India. However, Mahmood et al (2009Mahmood et al ( , 2011 reported nutrient release from leaf litter of three tree species in Bangladesh follows the order of K>N>P.…”

© iForest -Biogeosciences and Forestry IntroductionIn natural forests and man-made plantations, cycling of nutrient is an important aspect, as significant amounts of nutrients are returned to soil through litter fall and become available for nutrient cycling. Among nutrients, some are used in physiological responses and other stored in different plant organs, or returned to the soil through the litter and then partially absorbed by the root of trees (Breeman 1995). Uptake and release of nutrients are important factors at the stand level, because they represent the major fluxes through the system (Miller & Alpert 1984). Nutrient concentration in plant biomass is the result of the balance between nutrient uptake, plant growth and nutrient retranslocation, and the loss of these processes are likely to be influenced both by plant genetic make-up and soil fertility, as well as other environmental conditions (HagenThorn et al. 2004).Forest litter fall is the major flux responsible for nutrient transfer to soil (Parzych et al. 2008) and the growth and productivity of forest ecosystems depends mainly on the amount, the nature and the rate of decomposition of litter fall (Victor et al. 2001). Tree species can play an important role in nutrient cycling through different properties, such as the amount of litter produced, nutrients release and chemical composition of the litter (Rahajoe 2003). Different tree species involve different nutrient release patterns, which are related to litter quality and seasonal environmental factors (Khiewtam & Ramakrishnan 1993). Tracking nutrient returns through litter fall under different tree species is important to understand the dynamics of soil fertility.Soil and old leaf nutrient retranslocation, are the primary sources of nutrients in the leaves (Binkley & Sollins 1995, Piatek & Lee Allen 2000 and litter fall nutrient abundance is related to intensity of retranslocation processes in autumn (Parzych et al. 2008). The nutrient retranslocation, movement and transfer nutrients from the old leaves to the every year store, is an important process in nutrient dynamics in most ecosystems, especially broadleaf ecosystems (Killingbeck 1996, Duchesne et al. 2001). Retranslocation has been characterized as one of the most important strategies used by trees to conserve nutrients, which consequently influences competition, nutrient uptake, and productivity (Killingbeck 1996). Within the same community, foliar nutrient concentrations vary largely amongst different species and different individuals of the same species despite similar soil conditions (Niinemets & Kull 2003). The relative importance of site and species, as the factors determining nutrient concentrations in plant biomass, may differ depending on nutrient element and biomass fraction. Comparative studies of several species growing on the same soils allow a better understanding of species nutrient function (Hagen-Thorn et al. 2004).Different species and clones of poplar are commonly planted as fast-growing species in the world and some pa...

“…The results were very astonishing and it was observed that about 33.3% -83.3% carbon can be enhanced in soil by introducing tree species. It was also concluded that SOC was more where Populus deltoides was grown as compared to Eucalyptus (Singh et al, 1989).…”

. Furthermore, the study area has the potential of stocking 3607.61 Mt and sequestering 13214.67 Mt of CO 2 at the rate of 327232.46 t CO 2 per year. According to calculations, increasing the number of farm trees/ha, average CO 2 sequestration rate of the study area can be increased from 2.05 t CO 2 ha -1 yr -1 to 3.59 t CO 2 ha -1 yr -1 . The role of agroforestry as C sink in not negligible and it should be given a dire consideration in policies, especially, in low forest countries like Pakistan to meets the melinium goals of atmospheric C reduction.

“…Wider use of poplar can contribute to European Union goals to ensure 20% of its energy consumption from renewable resources until 2020 and continue further in the future (Jansons et al, 2014). Poplar based agroforestry has the capability of enhancing soil organic carbon up to 83% (Singh et al, 1989).…”

In poplar, one of the most used species of forestry and agroforestry, below ground biomass allocation plays an important role in providing anchorage as well as efficient nutrient and water distribution channel. Available literature on this aspect is not enough in hybrid Poplar, Populus euramaricana I-214. Therefore, the study was aimed at finding how this species developed its root system and how much belowground biomass was allocated in Forest System (FRS) and Agroforest System (AFS). This was done using soil excavation and root coring methods. Coarse roots were distributed in all directions but their number and proximal cross section area (CSA) were not uniform. In the case of AFS tree maximum CSA was distributed in the south and south-west direction while in FRS it was in the north-east and south-east direction. Fine roots were observed throughout the rooting zone along with coarse and medium roots up to a maximum depth of 2.4 m in FRS and 2.8 m in AFS. Total belowground biomass was higher in AFS tree (130 kg tree -1 ) than FRS tree (120 kg tree -1 ). But on hectare basis FRS accumulated (24.5 Mg ha ). However, if practiced in surplus agriculture area and considered the system as a whole, AFS allows grain production in lieu of some biomass deficit.
