Two agroforestry systemswere established on reclaimed mine sites in NE-Germany (Lusatia)
and Central Germany (Helmstedt). The yield potential and the sustainability of yields
were studied for different clones of poplar (Populus spp.), willow (Salix viminalis L.), and black
locust (Robinia pseudoacacia L.), considering different rotation periods (3-, 6-, and 9-yearrotation)
and approaches of soil amelioration (mineral fertiliser, compost).
