Based on our results and studies of Bungart and Huettl
(2002) S. viminalis is not adapted to such site conditions at all,
and, therefore, should not be considered furthermore.
Annual yields of R. pseudoacacia matched or even exceeded
the yields reported in the literature. Because of differences
in site conditions and planting densities results of different
sites cannot simply be compared. However, present
results clearly show that R. pseudoacacia is well adapted to
nutrient–poor sandy substrates and the low precipitation
regime.
