Abstract

The plantation of Pinus nigra on Pannonian dolomite slopes started in the early 20th century and continued in several waves. The main purpose of afforestation was to stop soil erosion on the slopes originally covered by grazed rock grasslands. It was also assumed that the pine improves the soil, thus makes possible the planting of other, economically more valuable tree species later on. Our work focused on the quantification of the effect of pine stands on the soil of closed dolomite grassland, a vegetation type frequently subjected to afforestation. Soil samples were taken from 3 depths (0-5, 5-10 and 10-15 cm) at 5-5 sites, then traditional chemical variables (pH, humus%, available N-, P-, K-content, etc) were determined in the laboratory. Under pine plantation acidification was significant only in the uppermost 5 cm. Regarding the humus content the pine plantation soils never exceeded the corresponding soil layers in the closed dolomite grassland. Most soil variables (Ca 2+3, Na +, K +, SO 4 2-, NH 4 +, etc.) had lower values in the pine plantation soil, than in the closed grassland. Soil amelioration on dolomite slopes, due to Pinus nigra plantations is not supported by our results.
