摘要：
The ameliorative species are considered to keep soils fertile as they return nutrients via litter-fall. Contents of nutrients in assimilatory tissues, litter and forest floor under five tree species in comparison with two low-density treatments with dominance of grass were investigated. The objective of this study was to answer whether the species differ in chemical properties of plant assimilatory tissues` matter (leaves and current year needles) and properties of soil humus layers under 18-year-old plantations. Weight of dry mass of forest-floor vegetation (herbs and litter) was higher in grass and broadleaves treatments compared to conifers. Birch had more foliar phosphorus and nitrogen while Mountain ash had more foliar potassium, calcium, magnesium compared to the other species. Mountain ash litter was higher in calcium. Forest floor humus (fermentation and humification horizons) showed similar contents of base cations under grass and broadleaves. Humus under conifers was higher in phosphorus.
