Abstract:

Short rotation high density plantations were established in the provinces of Soria and Madrid in 2009. Three poplar clones (I-214 and two improved new clones Oudenberg and Baldo) together with willow, black locust and sycamore species were included in the study. Representative samples were collected after a three year cycle. Species harvested in Madrid lead to a higher yield (10.9 odt/ha year as average of all species and/or clones) than species harvested in Soria (9.3 odt/ha year), as a consequence of better climate conditions and soil characteristics in Madrid. In general, the best yields were obtained for willow and I-214 poplar clone (higher than 16 t/ha year), followed by the others poplar clones, black locust and sycamore. Calorific value shows statistical differences among species and/or clones, although variations are lower than 0.4 MJ/kg. N, S and Cl contents are higher in Madrid than in Soria. The S contents obtained in Madrid usually exceed the limits of high quality pellets or briquettes for being utilised in the domestic sector (EN 14961-part 2 or part 3). The SRCs considered in this work show a good ash melting behaviour.
