Miscanthus Production
FIGURE 5.7
Mean dry biomass per surviving plant of M. × giganteus for different amendments in the
postmilitary soil.
ratio of humic and fulvic acids was 0.2–0.5, which indicates a weak humus
accumulation and active destruction of the soil mineral part. M. × giganteus
showed sufficient tolerance and good enough growth and development in
this postmining soil during 2 years of experimentation (Figure 5.8).
In order to determine the impact of amendments on the growth and development parameters of M. × giganteus, different amendments were applied:
mineral fertilizer with a balance of nutrients N 60 :P 60 :K 60 kg ha −1 ; ash of sunflower hulls or sewage sludge each in the amount 10 t ha −1 ; a mixture of ash
and sewage sludge (total 10 t ha −1 ); a double dose of sludge (20 t ha −1 ). The
amendments were incorporated into soil in a dry form once before planting.
