AB The steadily increasing demand for energy and concerns about climate change haveprompted countries to promote the use of renewable energy sources, including lignocellulosicbiomass. In this context, this work aims to assess the biomass production for energy purposes incrops with short rotation, as well as its effect on soil properties. Deciduous tree species were used,mainly Siberian elm (Ulmus pumila L.), black locust (Robinia pseudoacacia L.) and a hybrid poplar clone(Populus × euroamericana (Dode) Guinier, clone ‘AF2’). Four field trials were implemented, under twodifferent types of Mediterranean climate, where highly productive taxa were tested, in addition to themixed planting of a nitrogen-fixing species with a non-fixing one. Short-rotation coppices (SRCs) ofthese taxa yield about 12–14 t ha−1 year−1 of high-quality dry woody biomass, when fertilizers andirrigation water are supplied; generate 205–237 GJ ha−1 year−1 net and earnings of about EUR 1.5 perEUR 1 invested; and sequester into the soil 0.36–0.83 t ha−1 year−1 of C and 57 kg ha−1 year−1 of N.Therefore, these species raised as SRCs could improve degraded soils if the crop is properly managed,resulting in favorable economic, energy and CO2 emission balances. The use of mixed plantationscan bring economic and environmental gains, and the biomass transformation into high-quality chipsor pellets gives it added value
