Influence of a fertilizer stockpile on soil and water properties in a protected area – a case study from Tarnawa Wyżna in the Bieszczady National Park
Wpływ składowiska nawozów mineralnych na właściwości gleb i wód w obszarze chronionym na przykładzie Tarnawy Wyżnej w Bieszczadzkim Parku Narodowym

Opis:
After the displacement of population at the end of 1940s, soils of the upper San valley were subject to natural plant succession. In 1980s a large remediation programme was carried out in the studied area - the study was aimed to investigate the impact of one of the many abandoned fertilizer stockpiles. The research has shown only a relatively small and spatially limited influence of the stockpile on soil properties expressed mainly in pH changes and an increase in soil compactness. The obtained results indicate that soil, owing to its filtering role, prevents the spreading of calcium and phosphorus compounds, potentially able to eutrophicate the environment.

Opis:
In this paper, the current problems associated with the classification of brown earths, are presented. According to the Polish Soil Classification (PSC) (1989, 2011), base saturation is the main parameter for identifying eutrophic and dystrophic brown soils. In practice, however, it is not possible to determine the base saturation value in the field. Therefore, the aim of this study was to estimate the base saturation using a regression equation and create a field guide for brown earths, based on the pH value, measured using a Hellige indicator, and the calcium carbonate content. Determination of the pH ranges enabled the classification of brown earth types in the field. These results suggest that pH can be used as a proxy for base saturation especially in the field. A change in the hierarchy of soil (sub)types is proposed for the new Polish Soil Classification.

Soil cover of the north-eastern part of the Chernokhora Mts. (Ukraine)

Opis:
Soil cover in the investigated area of the Chernokhora Mts. is characterized by shallow soil profile containing a lot of unweathering crumbs of sandstone and specific character of organic matter. It is a result of very hard bedrock (especially sandstones), intensive morfphogenetic processes and very humid and cold climate. Under beech and spruce forests Dystric Cambisols and Cambic Leptosols prevail. In subalpine and alpine areas Umbric Leptosols, Lithic Leptosols and Dystric Regosols occur. The Pulmonario- Alnetum viridis vegetation occur on Hapli-Eutric Gleysols enriched by waters migrating among rocks.

Krzysik, Magdalena
Opis:
W pracy przedstawiono zróżnicowanie oraz charakterystykę gleb na obszarze Pienińskiego Parku Narodowego. Duże zróżnicowanie litologiczne, rzeźba terenu oraz warunki hydrologiczne wpływają na złożoność pokrywy glebowej na tym obszarze. Wyróżnione oraz scharakteryzowane typy gleb, występujące na terenie Pienińskiego Parku Narodowego to: rędziny (Rendzic Leptosols), pararędziny (Calcaric Cambisols), gleby brunatne (Cambisols), gleby glejowe (Gleysols), mady (Fluvisols) oraz gleby organiczne (Histosols).
Diversity and characteristic of soils in Pieniny National Park were discussed in this thesis. Variability of geology, relief, and hydrological conditions are responsible for very high diversity of soils in the Pieniny National Park. Previaling soils in the described area are as follows: Rendzic Leptosols, Calcaric Cambisols, Cambisols, Gleysols, Fluvisols and Histosols.

Opis:
Soil water properties are one of the most important soil features which determine water distribution and its availability for plants. Therefore, the aim of the study was to describe selected soil air-water properties and assess the size of spatial autocorrelation for soil properties. The soil samples were collected from a two-hectare field located in the mesoregion called Sępopol Lowland, in north-eastern Poland. The area is covered with Eutric Gleyic Cambisols formed from glaciolimnic sediments. Soil water retention properties as well as bulk and specific densities were analysed. The following soil pores and soil water capacities were calculated: macropores, mesopores, micropores, potential useful water retention (AWC – available water capacity), and among AWC, readily available water capacity (RAWC), and small pores available water capacity (SAWC). Geostatistical analyses as a function of the semivariogram and correlogram were carried out using Isatis Geovariance. The shares of the macro-, meso- and micropores in total porosity were similar. The lack of autocorrelation in the case of mesopores and micropores was noted. However, small autocorrelation was found in the case of SAWC, which was confirmed by a small nugget effect.

Biotic and abiotic determinants of soil organic matter stock and fine root biomass in mountain area temperate forests : examples from Cambisols under European beech, Norway spruce, and silver fir (Carpathians, Central Europe)

Opis:
Forest ecosystems significantly contribute to the global organic carbon (OC) pool, exhibiting high spatial heterogeneity in this respect. Some of the components of the OC pool in a forest (woody aboveground biomass (wAGB), coarse root biomass (CRB)) can be relatively easily estimated using readily available data from land observation and forest inventories, while some of the components of the OC pool are very difficult to determine (fine root biomass (FRB) and soil organic matter (SOM) stock). The main objectives of our study were to: (1) estimate the SOM stock; (2) estimate FRB; and (3) assess the relationship between both biotic (wAGB, forest age, foliage, stand density) and abiotic factors (climatic conditions, relief, soil properties) and SOM stocks and FRB in temperate forests in the Western Carpathians consisting of European beech, Norway spruce, and silver fir (32 forest inventory plots in total). We uncovered the highest wAGB in beech forests and highest SOM stocks under beech forest. FRB was the highest under fir forest. We noted a considerable impact of stand density on SOM stocks, particularly in beech and spruce forests. FRB content was mostly impacted by stand density only in beech forests without any discernible effects on other forest characteristics. We discovered significant impacts of relief-dependent factors and SOM stocks at all the studied sites. Our biomass and carbon models informed by more detailed environmental data led to reduce the uncertainty in over- and underestimation in Cambisols under beech, spruce, and fir forests for mountain temperate forest carbon pools.
