Identifying new criteria for assessing the impact on the ecosystem generated by the establishment of Jerusalem artichoke crops on difficult and floodable soils

Jerusalem Artichoke (Helianthus tuberosus L.) is a technical plant that manages to adapt very well unfriendly environments, even in polluted or poor nutrients soils and may serve the near future as an important raw material for food, chemical, pharmaceutical industries. Furthermore, growing rapidly, producing large amounts of biomass offers possibility be harvested up 2 times year, therefore presents high potential used field biofuel production. The plant's capacity multiply easily by developing small tubers soil, allowing production economically advantageous crops, can considered advantage producers, however this feature might drawback agricultural land owners considering invasive behavior. present paper aim assess two Artichokes crops established on marginal soils, assessing productivity extensive impact ecosystem, paying special attention invasiveness tendencies.
