“…Latter had also lesser inter-tree competition for underground resources like nutrients and moisture. Jha and Gupta (1991) and Banerjee et al (2009) have also suggested that providing extra irrigation, fertilizer doses, weeding and hoeing during the early age of intercropping enhanced tree growth resulting in more biomass accumulation (Singh and Sharma, 2007). Corroborating results were found in other studies like, agrisilviculture (Pingale et al, 2014), fruit trees (Raizada et al, 2013), young Populus deltoides plantation (Kern et al, 2004) and Acacia mangium (Danial et al, 1997).…”

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.

“…As the soil can affect poplar growth, these trees also affect different soil properties. Singh and Sharman (2007), and Augusto and Ranger (2002) stated that tree plantations influence soil physical, chemical and biological properties negatively or positively through litter fall, accretion and decomposition of organic matter. It seems that different poplar plantations of various quality and quantity have been able to change some soil properties in the Guilan plain in successive years.…”

ABSTRACT:We evaluated earthworm abundance and biomass in plantations of different poplar species and clones as well as the effect of some soil chemical and physical properties on them. (P. caspica), as endemic and endangered poplar species, were selected in this study. Earthworm abundance and biomass, soil texture, bulk and particle density (BD, PD), pH, organic carbon (OC), total nitrogen (N), available phosphorus (P) and exchangeable potassium (K) were evaluated. The results showed that the earthworm abundance and biomass, OC, P and N in P. d. 63/51 were higher than in the other poplar species and clones. The correlation coefficients showed a positive correlation of OC, N and a negative correlation of pH, clay, BD and P with earthworm biomass. Based on the results, compared to the other species and clones P. d. 63/51 creates favourable conditions to produce more organic matter and higher abundance and biomass of earthworms, hence it could be beneficial for maintaining the soil quality status for successive plantings.

“…Nonetheless, Deans et al, (1996) revealed that it is useful to know the stock of carbon s biomass per unit area, not only to facilitate choice of species but also to assess the impact of deforestation and re-growth rates on the global carbon cycle. Various interacting factors through which a tree influences carbon stock in the soil under agroforestry are addition of litter, maintenance of higher soil moisture content, reduced surface soil temperature, proliferated root system, enhanced biological activities and decreased risk of soil erosion (Singh and Rathod 2002, Schultz et al, 2004, Singh and Sharma 2007.…”
