Bio-energy and biomass system is a new scientific field, very interesting, where there can find new available information; however, there is also place for other novelties. A lot of projects and experiences regarding to what mentioned above, lead to the credence that forest biomass assume a fundamental role, inasmuch they constitute a renewable resource, already or easily present, in the environment. The main purpose of undertaking this study is to analyse the obtainable biomass yields from black locust (Robinia pseudoacacia L.) SRF. Four different plantations have been situated on lands of different fertilities in Italy and Albania. Neither irrigation nor fertilization has been applied. Two different methodologies of biennial harvesting have been compared on black locust plantation situated in Italy. The first one is the contemporary cutting and chipping, while the second with cutting, field seasoning of trees and then chipping. In Albania the analyses of planted trees were mainly focused on height and diameter growth. They revealed a good continuation which means that the bed conditions of abandoned terrain, and climate considering the extended drought period of last summer, don't affect the growth. 展开更多
