چکیده

Five genotypes of Short Rotation Coppice (SRC) willow: ‘Beagle’ ((S. viminalis ‘L810203’ x ‘L81102’) ‘Astrid’ male parent unknown), ‘Olof’ (S. ‘Bowles Hybrid’) schwerinii ‘L79069’) ‘L78195’ ‘L78101’) ‘Orm’) ‘Bjorn’). ‘Ashton Stott’ (S.viminalis S.dasyclados ‘Korso’, ‘Tora’ ‘Orm’), and ‘Torhild’ ‘79,069’) viminalis) S. ‘L78101’)) ‘Tora’) ((S.viminalis were grown in large mono-plots or within plots intimate mixtures. Over a seven year period half the harvested on two-year harvest cycle (three harvests) rest three-year (two harvests). At end this 7 trial there no significant differences between total dry weights stool survival, irrespective interval. With realisation importance finding for more regular crop management practices, experiment was continued further six years allowing round two three harvests. Results suggest that ultimately are yield penalties, although these may be minimised by careful appropriate clonal selection.

Evaluating ecosystem processes in willow short rotation coppice bioenergy plantations

Despite a growing body of research linking bioenergy cultivation to changing patterns of biodiversity, there has been remarkably little interest in how bioenergy plantations affect key ecosystem processes underpinning important ecosystem services. In this study, we compare how the processes of predation by ground arthropods and litter decomposition varied between Short Rotation Coppice (SRC) wi...

Potential benefits of commercial willow Short Rotation Coppice (SRC) for farm-scale plant and invertebrate communities in the agri-environment

The cultivation of bioenergy crops (BECs) represents a significant land-use change in agrienvironments, but their deployment has raised important issues globally regarding possible impacts on biodiversity. Few studies however, have systematically examined the effect of commercial scale bioenergy plantations on biodiversity in agri-ecosystems. In this study we investigate how the abundance and d...

The Effect of Chemical Soil Properties on Weed Infestation Structure in Willow (Salix L.) Short-Rotation Coppice

Differences in soil and habitat conditions, depending on the type of soil on which shrubby species of willow Salix L. are being grown for energy purposes, are reflected in weed infestation species diversity and the distinctiveness of these crops, and require an individual program of control and reduction of the abundance of competitive herbaceous vegetation. Our study aimed at determining soil ...
