    Calorific values of Miscanthus x giganteus biomass cultivated under suboptimal conditions in marginal soils

  • Original language description

    Miscanthus x giganteus is a second-generation biofuel crop with C4-photosynthesis, efficient water usage and high resilience to environmental conditions. From sustainability point of view is promising its cultivation on marginal soils, such as brownfields or contaminated sites. These soils however provide suboptimal cultivation conditions which can affect the quality of biomass including calorific values. In this work we have determined calorific values of young M. x giganteus biomass samples (1 or 2 years of cultivation) cultivated in various marginal soils. Obtained average calorific value was 17.44+-0.70 MJ/kg (dry mass), which is value comparable to firewood or middle quality brown coal. The variability of calorific values was quite large. Stems had slightly but significantly higher calorific values compared to leaves. Significantly higher calorific values were also obtained for field experiments than for pot experiments. Plant growth regulator (PGR) Stimpo increased significantly stems calorific value compared to non-treated plants while the calorific values of plants treated by PGR Charkor were comparable with non-treated control. Cultivation of M. x giganteus in petroleum industry contaminated soil resulted in the most significant reduction of calorific values of leaves besides order of magnitude reduction of quantity of biomass. Overall the results show that from energetic point of view, M. x giganteus provides highly energetic biomass even if cultivated in marginal soils and it is thus promising for sustainable use of such localities.
