... results of biofuel production reflect encouraging figures for some of the crops that have been tested, reaching productions even higher than those obtained by native species in natural soils in the vicinity of the restored lands. Table 1 shows the results obtained, with maximum productions reached of 95 t ha -1 of wet biomass for poplar clones AF2 (populusxcanadensis), with a level of fertilization F2, of 600 kg ha -1 NPK. After five years of growth, the annual productions are of 19 t ha -1 year -1 . ...
