We studied the spontaneous development of understory vegetation in a reclaimed fly ash landfill. Plots were reclaimed 11years earlier with sewage sludge, and boulder clay mixed with fly ash, and then afforested. Additionally, fertilisation with different doses of NPK was used. The treatments resulted in differences in the success of afforestation and in the spontaneous development of understory vegetation...
We have investigated the effect on growth of fertilisation versus biological nitrogen fixation by rhizobial nodules in Retama sphaerocarpa(L.) Boiss, a leafless leguminous shrub native to the Iberian Peninsula and North-West Africa that has generated interest for revegation of dry Mediterranean habitats. Our main objective was to optimise the formation of root nodules under nursery conditions and...
Seedling recruitment from forest soil polluted with heavy metals was studied in order to determine the revegetation potential of the seed bank. The soil samples were collected from untreated and fertilised Scots pine stands along a 8 km transect running SE from a copper-nickel smelter in SW Finland. The composition and size of the active seed bank and the survival of the germinated seedlings were...
