Different sunfleck characteristics, length and number of sunflecks per metre and sunfleck fractional area, were measured at different depths inside willow (Salix viminalis) canopy. All these characteristics depend on the pathlength of the direct solar radiation beam into the canopy, τ=L/sin h, where L is the downward cumulative leaf area index and h is the solar elevation. The mean sunfleck len...
Rising demand for bio-based products exerts growing pressure on natural resources such as wood. The agricultural technique of short rotation coppice (SRC) to produce dendromass from fast trees has gained relevance ease the wood forests. European-funded project Dendromass4Europe supports establishment SRC in Western Slovakia and its biomass use four new materials, context a developing bioeconomy...
No study has been previously completed on the range of sites, potential yield, and financial characteristics poplar short rotation coppice plantations (SRC) in Hungary. This paper conducts a literature survey to reveal biomass production such presents model that is used analyze their performance. The results indicate break-even-point between 6 8 oven-dry tons per hectare year once minimum cost ...
Root-associated fungi are key contributors to ecosystem functioning, however, the factors which determine community assembly are still relatively poorly understood. This study simultaneously quantified the roles of geographical distance, environmental heterogeneity and time in determining root-associated fungal community composition at the local scale within a short rotation coppice (SRC) willo...
