The missing data on bulk density make impossible the calculations of soil water retention, organic carbon pools and evaluation of the numerical indices of soil and forest habitat fertility and potential productivity. A common reason of skipping of bulk density measurement is the high content of rock fragments in soil, in particular in the subsoil layers, that may hamper the collection of samples with...
Both the international ISO standard and modern soil classifi cations and databases require soil pH measurement at a 1:5 soil:solution ratio, while the ratio 1:2.5 is still the most commonly used in Poland and other European countries. The transformation of laboratory practices is necessary, but it is also necessary to establish and validate a reliable procedure for converting soil pH at soil:solution...
The morphology and properties of the post−arable soils that influence the trophic status of forest habitats on the Barycz river terraces (south−western Poland) were analyzed. The fieldwork included the characterization of the soil, tree layer, and the vegetation of the forest floor, as required for the forest habitat evaluation. In the collected soil samples, a set of physico−chemical analysis was...
Lake sediments and peat bogs are “natural archives” of long-term changes in the quality of the natural environment at local and regional scales. However, due to technical difficulties the sediments of mountain lakes are rarely subject of geochemical analyses. Also, the sediments of Wielki Staw (1,225 m a.s.l.), the largest lake in the Karkonosze and entire Sudeten Mountains, have never been analyzed...
Due to the ease and low cost of implementation, a commonly used method of determining the humus content in soils is the loss-on-ignition (LOI) method. Several regression equations and transformation factors are reported for LOI conversion to soil organic matter (SOM) or total organic carbon (TOC) content. The vast majority of the conversion factors have been developed for surface horizons of lowland...
Chemical properties and fertility of soils were compared under spruce, mixed and beech stands in four types of forest habitat (mountain broadleaf forest, mountain mixed broadleaf forest, mountain mixed coniferous forest and mountain coniferous forest) in 373 sites of forest monitoring in the Stołowe Mountains National Park, SW Poland. Soils under the spruce stands had higher organic carbon pools in...
Deep dystric Cambisols developed on the homogenous regoliths of granite in the Stołowe Mountains National Park (SW Poland). In general, the soils have a texture of gravelly sandy loam, apparently silty, the strong acid reaction and the base saturation below 30% throughout the profile (oligotrophic variant). Only the soils developed in lower parts of slopes have a base saturation up to 40−50% or more...
The rapid retreat of the Werenskiold Glacier (the Svalbard archipelago, High Arctic) is leading to an extensive broadening of the proglacial zone covered with recent moraine till on older glacigenic deposits or directly on bedrock schists. To study the type and intensity of initial soil development under a harsh periglacial climate, a chronosequence of six soils was established between the glacier...
