Opis:
In the 40 fir localities in the Sudety Mountains, varying in site conditions and the degree of natural regeneration development were taken soil samples from the mineral horizon and were subjected to particle size distribution analysis. The best regeneration of fir stands has been reported on medium-textured soils, containing a few percents of the clay fraction and from 50to 60% of sand.The poorest regeneration was reported on silty soils, located in the lower parts of slopes. In comparision with the Carpathians, spectrum of conditions in which firs grow in the Sudety Mountains is clearly shifted from coarse-textured soils to medium-textured soils.

Opis:
The purpose of this study was to determine the basic physico-chemical properties of soil in silver fir stands with different stage of natural regeneration. The investigations were carried out in south-west part of Poland – in the Sudety Mountains. From 854 silver fir stands, 40 testing sites, varying in terms of habitat conditions and degree of natural regeneration, were selected. Soil samples were collected from litter (organic horizon – O) with a thickness of 7–15 cm and from mineral A horizon lying up to 20 cm below the organic horizon and were then analysed for pH, EC, C org., total N, exchangeable cations (Ca, Mg, K, Na, H and Al), soluble Mn, Fe, Zn and Pb as well as particle size distribution (samples from A horizon). The analysed soil samples are characterized by very high acidity and low content of bases. According to the performed statistical tests, none of the factors analysed within the samples tested has a significant impact on the natural regeneration of silver fir. The only dependence between potassium content in soil and the regeneration of silver fir in the Sudety Mountains is close to statistically significance.
