Samples were taken from 50 Jatropha bushes destructively during a randomized research trial on 100 ha in Luxor, Upper Egypt, on
behalf of the Atmosphere Protect GmbH. This trial determined for the first time on a scientifically concrete basis the complete upper as well as subsurface biomass of an energy
plant established in a desert environment. These results are of utmost importance to derive economic and ecologic parameters.
