    Opis:
    An important question stated in the presented paper is: Could rotifers be the indicators of climate change in the Antarctic environments? Rotifers are one of the most important components of the invertebrate fauna of the Antarctic freshwater and terrestrial ecosystems. However, investigations of their distribution, diversity and an ecological role in the environment have been widely neglected, mainly due to the methodological and taxonomical difficulties. During the investigations 176 species of rotifers were found, including the endemic and cosmopolitan species. Their existence is directly proportional to microvariations of humidity factor. Scientists still have poor knowledge about the occurrence of rotifer species in recently studied habitats e.g. cryoconite holes, nunataks or soil. Probably rotifers could be the indicators of climate change in the Antarctic freshwater and terrestrial ecosystems but more investigations and monitoring studies are needed.

    Opis:
    The distribution of total lithium content with depth was studied in soils of selected forest ecosystems, with regard to their physicochemical properties and possible anthropogenic impact. The six soil profiles, representing forest soils, were selected for the study: Udipsamments formed from sandr sand, eolian sand and alluvial sand, and Haplorthods Humic formed from eolian sand, Dystrochrepts formed from alluvial silt and Eutrochrepts formed from boulder loam. The total Li content was determined after previously dissolving the samples in a mixture of concentrated acids: hydrofluoric and nitric (HF+HNO3). The content of Li in solutions was determined using the FAS method on PU-9100 X Philips spectrometer. The total lithium content in studied soils under investigations occurs in range of 1.63 to 229.68 mg kg-1 and was considerably lower in organic horizons (1.63-8.07 mg kg-1 ) than in mineral (17.58-229.68 mg kg-1). The concentration of lithium in subhorizons of forest litter increases according to the litter decomposition degree (01<0f<0fh). The Li concentrations found in all forest soils formed from sand were much higher than its natural content in surface mineral horizons of arable soils 1.30-56.00 mg kg-1. The total lithium content in studied soils was negative statistically correlated with the content of organic carbon (-0.6062), silt and clay fraction (-0.7131 and -0.6322), hydrolytic acidity (-0.5222), sum of exchangeable bases (-0.6196) and cation exchange capacity (-0.6277).

    Opis:
    Colonization of terrestrial ecosystems by the first land plants, and their subsequent expansion and diversification, were crucial for the life on the Earth. However, our understanding of these processes is still relatively poor. Recent intensification of studies on various plant organisms have identified the plant cell walls are those structures, which played a key role in adaptive processes during the evolution of land plants. Cell wall as a structure protecting protoplasts and showing a high structural plasticity was one of the primary subjects to changes, giving plants the new properties and capabilities, which undoubtedly contributed to the evolutionary success of land plants. In this paper, the current state of knowledge about some main components of the cell walls (cellulose, hemicelluloses, pectins and lignins) and their evolutionary alterations, as preadaptive features for the land colonization and the plant taxa diversification, is summarized. Some aspects related to the biosynthesis and modification of the cell wall components, with particular emphasis on the mechanism of transglycosylation, are also discussed. In addition, new surprising discoveries related to the composition of various cell walls, which change how we perceive their evolution, are presented, such as the presence of lignin in red algae or MLG (1→3),(1→4)-β-D-glucan in horsetails. Currently, several new and promising projects, regarding the cell wall, have started, deciphering its structure, composition and metabolism in the evolutionary context. That additional information will allow us to better understand the processes leading to the terrestrialization and the evolution of extant land plants.

    Opis:
    In the last Vistulian glacial period, the profiles of periglacial perstructions and the profiles of old cryosols were formed in the extra glacial and gradually released from retreating continental glacier regions, originally in conditions of over 6-8 ka existing arctic desert before approximately 14.5 ka, and then from 14.5 to 10.5 ka BP, in the changing short rhythms of glacier deserts, shrub and park tundras as well as in short lasting pine-birch and birch forests. The whole profile thickness of the remaning periglacial horizons of the pleistocene paleosoils at the earth surface consists of a sequence or series of periglacial frost perstruction zones. In the cryogenic perstruction process of surface and subsurface sediment layers in the periglacial environment there were diagnostic horizons - cryosideric - crBv, cryoargillic - crBt, and cryospodic - crBk formed. Their localisation in the perstruction profile, in the soil horizons profile and the grain size profile, with readily recognisable associations of cold climate characteristics, may be used for quantification and diagnosis of rusty and parabrown paleosoils in the framework of superordinatektaxonomic unit of paleocryosols.

    Opis:
    Fungi are among the most important organisms on earth, and they are essential components of terrestrial ecosystems. Their reproductive structures are strictly dependent and affected by environmental conditions, and community dynamics over time and space may be indirect indicators of the health status of forests. We combined macrofungal biodiversity indices in eight Mediterranean forests in Italy and surveyed 160 plots by standardized surveys, to evaluate the role of macrofungi as early predictors of change in the forest structure. The results show that indices of fungal diversity are influenced by geographic and floristic conditions, and inter- and intra-annual temperature and rainfall fluctuations affect the formation of fungal fruiting bodies. These findings suggest that environmental changes could be reflected by macrofungi, and conservation initiatives should consider the pivotal role that fungi play in biodiversity monitoring.

    Opis:
    Four pedons of Alfisols were selected from the Experimental Station Mochełek to study chemical composition of the soil material. The study area is located in the south-western border of the Krajeńska Upland, on the border of two geomorphological formations: erosion surface of floating waters (fluviglacial formation) and rolling ground moraine (glacial material). The investigated soils were classified as Typical Hapludalfs (pedon 11,21 and 26) and Typical Glossudalfs (pedon 7). Chemical composition was analysed using the following methods: fusion with Na2CO3 and dissolving in the HF and HCIO4 mixture. Results were presented in an oxide form and molar ratios (SiO2/R2O3; SiO2/Al2O3; Si02/Fe203; Al2O3/Fe203) were calculated. In the studied soils, the content of SiO2 was from 78.21 to 90.00 %. The lowest SiO2 content was found in the illuvial horizons. Otherwise the illuvial process influenced Al2O3 and Fe2CO3 distribution, the highest amounts of which were found in the illuvial horizons. TiO2 (0.15 to 0.63 %), had similar profile distribution to K2O (1.74-3.88 %) and Na20 (0.61- 1.05 %). CaO and MgO contents were the highest in the parent material, including CaCO3 (pedon 11 and 26). However, the highest amount of MnO was observed in the surface horizons (0.56-0.58 %). Chemical composition of the studied soil material indicated a large influence of the illuvial process and particle-size on the total content and profile distribution of the analysed soil. However, the evident influence of parent material from which the analysed soils were formed, was not found.

    Opis:
    The study site, 2700 m a.s.l., is located in the central Taiwan. A globally rare combination of the mean temperature (ca. 9.5 °C) and total annual precipitation (ca. 4100 mm) makes studies on pedogenic and edaphic processes of the moist soils in this area worthwhile. The study was undertaken to investigate distribution and characteristics of humic substances in this subalpine forest ecosystem. Fulvic acids comprised a higher total organic carbon fraction (1.8 to 25%) than humic acids (1.1 to 13.4%). Fulvic acids were more mobile and migrated downwards to deeper horizons. Comparatively, humic acids were distributed more in the surface horizons. The hu- mification index, based on E4/E6, showed that humification varied in different horizons even in the same profile. The AlogK and RF values indicate that the types of humic acids extracted from Tsuga forest soil are grouped as P or A types, whereas Rp or B types are in Picea forest soil, suggesting a high degree of humification of humic acids in such soils. Features of the absorption spectra were consistent with the classification of humic acids with A logK and RF values. Humification indices and humic acid types in these subalpine soils indicate that they are similar to acidic soils elsewhere with abundant rainfall and cold climate.

    Opis:
    In Poland, soil cover has been identified in detail in terms of spatial variability which resulted in soil records that comprise data on soil properties put in order according to the criteria of administrative and physiographic division. These data were not available in the numerical format till quite recently which meant that their application did not fully meet present requirements of agriculture, environment and landscape conservation, modification of functions, etc. The newly created numerical soil map at the scale of 1.500 000 corrects this difficulty. The main information content of the map at the scale of 1:500 000 covers complexes of soil usefulness and soil types and subtypes. Basic characteristics such as granulometric composition, origin of the parent rock and land use attributes, i.e.: forest, grassland, arable land, waters or barren land, are also included. Apart from the soil coverage, the map contains 13 topographic coverages.

    Opis:
    The research was conducted in 1991-1997 on the soils from arable fields situated near Łódź. To the detailed research there were stated four soil profiles which were different as regards their grain composition (two sand and two silt soils, all shallow) and typology (two profiles of brown leached soils, one pseudopodzolic-gley soil and one fallow glossic grey-brown podzolic soil). Qualification of the directions of the alterations in the content of organic carbon and basic macroelements (P, K, Mg) in soil and hesitation of reaction, hydrolytic acidity and content of the exchangeable basic cations in the soil sorptive complex were the main target of our research. The result of the 7-year-long research showed that different changes took place in the features of the examined soils. However, the exact assignment of the direction of these alteractions is extremely complex and does not warrant getting a satisfying answer. It is the result of taking various agriculture actions which are necessary to the appropriate maintenance of the ecosystems.

    Opis:
    The aim of the present research work was to evaluate the influence of lithogenic conditions on the physico-chemical properties, quantity and quality of humus components in the black earths from the Małopolska Upland. Soil samples were collected from 5 soil profiles which represented proper black earth (profiles No. 1-4) and degraded black earth (profile No. 5). All the investigated soils were under sward. The examined black earths were characterised by different physico-chemical properties strongly related to the parent rock type. Their pH level and sorption capability were decreasing with a decrease in the clay content of the soil texture. Humus resources were the lowest in sandy black earths (average 212 t ha-1) and the highest in the black earh derived from clay (454 t ha1). In the humus composition of the examined black earths, humic acids dominated over fulvic acids. In the A horizons, the Ch:Cf ratio was close to 1, and lower in the upper parts of these horizons which is typical of turf soils. Humus horizons in some of the investigated black earths were classified as epipedon anthropoid according to phosphorus content soluble in 1% citric acid (109 P kg-1 soil).

He discusses this problem in comparison to other natural sciences far better known. As there are no useful teaching aids, the author draws our attention to the importance of the soil monolith, soil displays, posters and atlases. Moreover, he emphasises the role of Internet in education. Finally, he proposes to found a soil profile museum for educational purposes.

    Opis:
    The present study aims to evaluate the mutagenic potential of secondary metabolites viz. anthraquinone, β-sitosterol and quercetin present in Alternanthera tenella and their related analogus compounds similar in their molecular structure. Nine similar putative allelochemicals analogus to each of anthraquninone, β-sitosterol and quercetin respectively were selected, a total of twenty seven similar chemicals were studied for mutagenicity prediction. Ames mutagenicity prediction was carried out by using T.E.S.T. (Toxicity Estimation Software Tool) of USEPA. All experimental metadata were obtained from Toxicity Benchmark and T.E.S.T. The results clearly indicated that the allelochemicals, anthraquinone and its related eight compounds were mutagenic positive except benzanthrone (mutagenic negative) but all experimental data were found mutagenic positive. β-sitosterol showed mutagenic negative in both experimental and predicted value. It’s three related compounds were mutagenic positive but rest six related compounds mutagenic negative in predicted value while in experimental data, seven compounds were found mutagenic positive and rest two mutagenic negative. In case of quercetin, both data were obtained mutagenic positive while in related compounds, seven compounds were found to be mutagenic positive and two compounds mutagenic negative in predicted value. All were found to be mutagenic positive in experimental metadata. Such findings poses a curiosity that are there any possibilities of conversion or substitution in the position of aromatic ring of allelochemicals when present in soil? Because allelopathy depends upon several environmental stressors and mutagenicity may be induced by allelochemicals. It is suggesting for future research to detect metabolic pathway and mechanism of allelochemicals formation in A. tenella in presence of toxins in soil and to validate with other available 2D and 3D softwares.

    Opis:
    Anthropogenic alterations of the recent millennia of our era, in the loess areas of the Lublin Upland are clearly visible in the composition and character of the sediments that fill river valleys. This paper is an attempt to review this issue on the example of a small river valley that runs through the loess relief regions near Lublin. Samples were taken from deep drilling (up to 6 m) in the three cross-sections of the valley (Ożarów, Jastków, Snopków). A total of 172 samples taken from 5 drillings were investigated. The results obtained allow to conclude that delluvial processes dominated in the course of sediment formation that filled the Ciemięga river valley. Those delluvial processes started in the Neolyth by climatic changes and cutting down forests for the incoming agriculture - and have been intensified since the Middle Ages up till now. It is seen in a clear correlation between the growing part of ash components and mineral interbeddings in the peat deposits, as well as in the presence of cereal grains and weed pollen from cultivated fields in the investigated samples. In the chemical composition of the sediments, anthropogenic enrichment of K, P, Fe, Mn, Pb, Cr, Cu, Zn, and Co is observed.

    Opis:
    Specific, humid climate of mountain areas has a great influence on the properties of soils and vegetation, as well as on the mutual relations between these inseparable elements of ecosystems. Research on the interdependence between soils and natural vegetation was carried out on ' the mountain meadows of the Bieszczady National Park. In conditions of the cooler and more humid mountain climate the peculiar character of the soils lies in the presence of organic surface horizon of properties varying considerably from the properties of deeper mineral horizons. This horizon is of great importance in the protection of scarce elements. It prevents pollutants from reaching the ecosystem. It influences the soil water economy. It prevents erosion. This buffer element of the mountain soils requires special protection - in the Bieszczady Mountains the erosion of the mountain meadow soils is only noticeable where the covering vegetation and the organic surface soil horizon were destroyed, e.g. on tourist tracks. The plants of the Bieszczady mountain meadows, together with their direct product - the organic surface soil horizon, prevents the chemical erosion of the mountain meadows, reducing the leaching of many biogenous elements, e.g. calcium.

    The aim of this study was to analyse the acidity and buffer abilities of selected soils occurring within terrestrial (forest, arable and meadow) ecosystems, under specific form of protection within the Lasy Janowskie Landscape Park. The results of the study indicate that the very acid and acid reaction of the soil environment is the result of natural processes, such as relations between mother rock and plant cover (low pH, high value of hydrolytic and exchangeable acidity, and high content of mobile aluminum), and low degree of saturation of the sorption complex with bases. The greatest buffering abilities showed typic gley soil (Dystric Gleysol), peat soil (Terric Histosol), and accumulation horizons of other soil types.

    Opis:
    The aim of this work was to compile characteristics of some selected physical, physico-chemical and chemical properties of the reclaimed hydrogenic soils in the meadow part of the Przedmoście bog in the context of new forming plant communities. Melioration work conducted in this area before the Second World War ended peat accumulation processes. Consequently, drying peat began to disintegrate and mineralise. Analyses of floral lists proved that the existing vegetation replaced the original bog plant communities, which flourished in this area in the past. Descriptions of profiles point to the existence of mixed formations (gyttja, peat) often containing high quantities of CaCO3. Peat formations present in the profiles are usually at the advanced degree of decomposition (H>7) and contain substantial quantities of ash. This high degree of ash content and bulk density results in strong compaction and muddy soil horizons. A low coefficient of C/N showed intense mineralization of organic matter in the upper soil horizons.

    Opis:
    Studies considering hummocks and hollows structure of bog forests were carried out in the Stare Biele Reserve in the Knyszyn Forest. The aim of the study was better recognition of bog forests spatial structure including recognition of soil chemical composition of hummocks and hollows. The bog forest communities in Stare Biele Reserve have various percentage of hummocks. The hummocks have similar morphological structure and are distinctly separated from hollows in all four bog forest communities. Degree of hummocks development and their morphological structure have big impact on plant distribution on their surface. Soil chemical properties are one of the factors, which influence floral abundance and composition of microcenoses. Soil reaction and calcium content, among other measured properties, exert the biggest influence on the floral abundance and composition of microcenoses.

    Opis:
    Twelve samples, collected from four pedons of cultivated soils (black earths) were analyzed by sequential extraction to characterize the role of free iron oxides in the association of lead and cadmium. Amounts of lead and cadmium retained varied from 11 to 89.3% of the total Pb and from 4.8 to 48.7% of the total Cd. Metals associated with amorphous Fe oxides are at least ten times higher than with crystalline Fe forms. Under the existing soil conditions (high pH and CaCO3 content) free iron oxides are components of great importance in the Pb and Cd binding process. However, the results may indicate a stronger association of Pb than Cd with iron oxides in the studied black earths.

    Opis:
    The reports of Intergovernmental Panel for Climate Change indicate that the growing emission of greenhouse gases, produced from the combustion of fossil fuels, mainly carbon dioxide, leads to negative climate changes. Therefore, the methods of mitigating the greenhouse gases emission to the atmosphere, especially of carbon dioxide, are being sought. Numerous studies are focused on so-called geological sequestration, i.e. injecting carbon dioxide to appropriate geological strata or ocean waters. One of the methods, which are not fully utilized, is the application of appropriate techniques in agriculture. The plant production in agriculture is based on the absorption of carbon dioxide in the photosynthesis process. Increasing the plant production directly leads to the absorption of carbon dioxide. Therefore, investigation of carbon dioxide absorption by particular crops is a key issue. In Poland, ca. 7.6 mln ha of cereals is cultivated, including: rye, wheat, triticale, oat and barley. These plants absorb approximately 23.8 mln t C annually, including 9.8 mln t C/yr in grains, 9.4 mln t C/yr in straw and 4.7 mln t C/yr in roots. The China, these cereals are cultivated on the area over 24 mln ha and absorb 98.9 mln t C/yr, including 55 mln tC/yr in grains, 36 in straw, and 7.9 mln t C/yr in roots. The second direction for mitigating the carbon dioxide emission into the atmosphere involves substituting fossil fuels with renewable energy sources to deliver primary energy. Cultivation of winter cereals as cover crops may lead to the enhancement of carbon dioxide removal from the atmosphere in the course of their growth. Moreover, the produced biomass can be used for energy generation.
    Z raportów Międzynarodowego Zespołu ds. Zmian Klimatu (IPCC) wynika, że rosnąca emisja gazów cieplarnianych, głównie dwutlenku węgla pochodzącego ze spalania paliw kopalnych, prowadzi do negatywnych zmian klimatu. Wobec takiego zagrożenia poszukuje się metod prowadzących do ograniczenia emisji do atmosfery gazów cieplarnianych, w szczególności dwutlenku węgla. Badania nad ograniczeniem emisji dwutlenku węgla koncentrują się głównie nad tzw. sekwestracją geologiczną, czyli zatłaczaniem dwutlenku węgla do odpowiednich pokładów geologicznych lub wód oceanicznych. Jednym ze sposobów, nie w pełni wykorzystanych, jest stosowanie odpowiednich technik w rolnictwie. Roślinna produkcja w rolnictwie oparta jest na absorpcji dwutlenku węgla w procesie fotosyntezy. Zwiększenie produkcji roślinnej prowadzi bezpośrednio do wzrostu absorpcji dwutlenku węgla. Dlatego ważnym zagadnieniem jest poznanie absorpcji dwutlenku węgla przez poszczególne uprawy. W Polsce na obszarze o powierzchni 7,6 mln ha uprawia się zboża: żyto, pszenicę, pszenżyto, owies i jęczmień. Rośliny te absorbują rocznie około 23,8 mln t C, z tego 9,8 mln t C/rok w ziarnach, 9,4 mln t C/rok w słomie i 4,7 mln t C/rok w korzeniach. W Chinach zboża te uprawiane są na powierzchni przekraczającej 24 mln ha i absorbują 98,9 mln t C/rok, z tego w ziarnach 55 mln t C/rok, w słomie 36 mln t C/rok, a 7,9 mln t C/rok w korzeniach. Drugim kierunkiem ograniczania emisji dwutlenku węgla do atmosfery jest zastępowanie paliw kopalnych, stanowiących źródło energii pierwotnej, przez odnawialne źródła energii. Uprawa zbóż ozimych jako roślin okrywowych może prowadzić do intensyfikacji usuwania dwutlenku węgla z atmosfery. Ponadto wyprodukowana biomasa może być wykorzystana jako surowiec do produkcji energii.

    Twenty different soils were investigated. The soils varied in their acidification degree, granulometric composition and a carbon content. The investigated soils were collected from arable land, meadows and forests. Humic compounds were extracted from the soil according to the Konowowa and Bielczikova's method. Very high quantitative and qualitative differentiation\was observed. It was related to the soil type and utilisation system. Low but differentiated quantities of humic compounds extracted by 0.05 M H2SO4 were found in the samples of the analysed soils. In the extract of pyrophosphate and sodium base as well as in the extract of sodium base, there were more fulvic acids than humic acids which was reflected in the narrow Ckh:Ckf ratio, particularly in the forest soils. In addition very high proportion of non-hydrolysing carbon was observed. Its content ranged from 52 to 84%. The highest proportion of this fraction was found in the soils agriculturally utilised.

    Opis:
    The Błędów Desert is situated in the south of Poland. In this area, sand-gravel sediments predominate. The origin of the Błędów Desert is not associated with climatic conditions but with a strong development of excavation industry which started in the region in the Middle Ages. The surrounding forests became the main fuel source for the development of mining and metallurgical industry. Therefore, the area of the Błędów Desert was completely deforested. The paper presents reasons for the acceleration of biocenotical systems in the investigation area. For this purpose, transects representative for the following stages of plants successions: stage of encroachment plants, stage of sodding, stage of bushes (shrubs), stage of biogroup and stage of afforestation were made. Plant succession in the investigated transects developed in a multidirectional way. The ground for plants settling in the Błędów Desert represents fluvoiglacial, fluvial and aeolian sand with various grain sizes. Locally, in the old deflation fields, relict horizons of older podzolic and rust-coloured soil are the ground for the invading plants. The process of plant and soil succession takes place at the same time. Content of the available mineral elements in the initial horizons is different; it depends on the plant species in the places where these horizons developed.

    Opis:
    This paper presents pedological research in Žutica forest in northern Croatia. The most common soil types found in this area belong to the hydromorphic class (Pseudogley, pseudo- gley-gley, eugley, fluvisol) except technogenic soils formed as a result of intensive oil exploitation. Some main chemical and physical characteristics of soils are given. For forest productivity the most productive combination of soils are hypogley and pseudogley-gleysol and minimal productivity is in heavy amphygleic soils. An increase of heavy metals occurs in flooded soils in Žutica from nearby agricultural land. A high concentration of active phosphorus,and nitrogen can verify the influence of field fertilisers on the forest. Levels of cadmium found in technogenic soils exceed the permitted concentration. A large amount of CaCO3 in relation to natural forest soils can be found in technogenic soils because of quick lime disposal after oil spills and also pH increase and a nutrition and humus decrease.

    Opis:
    The Macroregion of the Mazurian Lake District and the adjoining mesoregion of the Sępopol Plain were formed during Baltic glaciation and in the post-glacial period. The existing habitat differentiation, especially large variations in the soil cover, is divided into three distinct landscape zones. The northern areas of the district are typical heavy and very heavy soils, composed of tight clays and loams, represented by brown soils and black earths. They contribute to the ecosystem stability. Hydrogenic soils occupy only a small area. Agricultural production, when carried out correctly, should not threaten the habitat and should be in harmony with the area in question. The central, moraine area of the Mazurian Lake District, with unique natural qualities, is comprised of different soil forms and various soil covers. Brown and lessive soils are dominant among mineral soils. Deluvial soils are common, which is a warning sign on the danger of erosion. Contribution of hydrogenic soils is clearly seen. Protection of these soils, as well as re-naturalisation of the selected areas, is becoming vital. This area badly requires ecological farming. Light and very light soils, mainly rusty and podzo! soils, accompanied by large areas of sensitive for transformation hydrogenic, muck, and mucky soils occur in the southern part of the district, in the area of outwash plains. Outwash plains call for complex solutions to improve the quality of their mineral soils, as well as utilisation and protection of hydrogenic soils.

    Opis:
    Contribution of clay mineral phase (<2 um) and organic matter to the cation exchange capacity (CEC) of two clayey soils (gleyic black earths from Gniew) was investigated. The XRD analysis showed dominance of illite and mixed laver illite/smectite as well as the presence of smectite, chlorite and trace of kaolinite in the clay fraction of studied soils. CEC of the soils ranged between 22.08-32.64 cmol(+)/kg. After removal of organic matter with 30% H2O2, CEC the above values decreased significantly. However, the CEC of organic and inorganic components is not an additive. This may be explained by the formation of organo-mineral complexes, which might lower the CEC of the soil as a whole.

    Opis:
    Quantity of some groups of microorganisms and dehydrogenase activity were determined in the top soil layer (0-10 cm) of natural and drained peatland. High soil moisture (85 to 90%) in the natural peatland accounted for the reduction of fungi and cellulolytic microorganisms which can reflect a restricted process of peat mineralization. In late summer (September), peat-muck soils of drained meadows supported rather high numbers of cellulolytic microflora except for the Modzelówka peatland that was highly decomposed. In the alaer peat with high degree of mucking and low moisture content (55-63%) fungi were abundant. Dehydrogenase activity was the highest (153 to 181 ul H2 g-1) in natural peats with high moisture content (80-89%) and the lowest (5-13 ul H2 g-1) in alder peats with high degree of mucking. Thus, moisture and degree of peat mucking affect development of microorganisms and dehydrogenase activity causing more or less intense mineralization of organic matter.

    Opis:
    Investigations have been carried out on the soil material taken from 46 profiles representing lithogenic soils from non-forest areas of the Tatra National Park. When selecting soil material an altitude above sea level (over 1250 m a.s.l.), a rock parent type (non-calcareous and calcareous) were taken into account, in case of non calcerous soils, the weakly developed soils - rankers were selected. On the basis of the investigetions the following conclusions have been drawn: sorption properties of ectohumus horizons in most of investigated lithogenic soils (rankers and rendzinas) are differ- enciated and formed under the influence of parent rocks. Ectohumus of Oh horizons of rankers sorbed exchangeable cations in following order H+>Ca2+≥Mg2+>K+>Na+. In composition of cations in Oh horizons of rendzinas dominated cations of calcium and the order was as follows: Ca2+>Mg2+>H+>K+≥Na+. In ectohumus of Oh horizons of rendzinas occurring under bilberry heath and pine dwarf and rankers the composition of exchangeable ions as well as a degree of base saturation were close. In investigated soils sorption properties of mineral or organic-mineral horizons AC or ABC, occurring in direct contact with the parent rock, were formed under the influence of lithogenic factor.

    Opis:
    The aim of the work was to investigate various soils properties in the partial forest reserve "Krzywiczyny", in the Namysłów Forest Inspectorate (Opole Voivodeship). It was found that upper soil horizons, including organic, humic and illuvial ones, indicated clear accumulation of Mn, Zn, Cu, Pb and Cd. However, a tendency to diminution of these elements content with profile depth was noted. High positive correlation was stated between organic matter content and Mn, Zn, and Cu amounts in the brown leached soils studied.

    Opis:
    Studies on the soils in forest ecosystems in breaks of the rivers Jeleń and Sopot were carried out in the years 1997-1998. Although the rivers differ in length, catchment area, amount of water carried and breadth of the valleys, the most important factors affecting soil formation and their spatial differentiation are similar: bedrock, relief, water drainage, natural type of water management, position of the ground water-table relative to the river water level, and chemistry of spring and soil waters. Steep slopes of the valleys covered with poor and highly acidic podzolic soils are usually overgrown with fir and pine phytocenoses, or rarely, with mixed oak-pine forests. The bottoms are often characterised by longitudinal duality of the flood-plain benches. In the drier area close to the river beds under ash-alder forests, there are more fertile gley soils and gley podzols. Poorer and more acidic localities are occupied by mixed forests with spruce. In permanently moist fragments of the benches at the foot of the slopes and in depressions with stagnant water weakly acidic peat-mud and peat soils occur overgrown with bog-alder forests. Peculiarities of these areas are low peat-bogs suspended even up to 4-6 m above the water-table of the river.

    Opis:
    Natural variability of pseudogley forest soils in the Białowieża National Park was characterised on the basis of five soil exposures. Two of them were located in a water-logged site, one in a mound one in a patch with dominance of deciduous trees, and one in a spruce biogrup. It was found that pseudogley soils of a natural moist deciduous forest show additional differentiation in the form of characteristic micromosaics. There is a pronounced impact of the species structure in a treestand, uprooted trees and hoofed mammals on the properties of the soil cover. Changes resulting from the above biotic factory were observed in all the analysed physical, physico-chemical and chemical soil parameters.

    Opis:
    Eight sandy and three loess forest and arable soils taken from the S-E region of Poland were used in the study. The following fractions of C were determined: total organic carbon, fraction soluble in 0.5 mol NaOH dm-3 (humic acids + fulvic acids), humic acids, fulvic acids, fraction soluble in 0.5 mol H2SO4 dm-3 (hemicelluloses) and residue. Quantity and quality of organic matter depended on horizon and soil use. The highest content was shown by fraction of humus acids and residue, whereas the lowest - hemicelluloses fraction. In most soils C ratio of humic to fulvic acids exceeded 1.0. On average, in humus horizons, it was higher in arable than in forest soils and in loess as against sandy soils. In sandy soils, a slightly higher content of humus fraction and lower residue one than in loess soils was found.

    Opis:
    The aim of the studies carried out in the natural oak-hornbeam forest Tilio-Carpinetum typicum and in the degenerated form in the stage of pinetization Pinus-Lamniastrum, was to obtain and compare qualitative-quantitative structures of soil fungi communities in two different oak-hornbeam forests. This degenerated form of oak-hornbeam forest is the result of removing the natural tree population (typical oak-hornbeam forest) and re-afforesting the resultant vacant area with pines. The study plots were located in such a way that the variations of soil fungi communities were affected only by seasonal changes in the vegetation of the degenerated oak-hornbeam forest Pinus-Lamnias- trum. The soils in both study plots are typical forest grey-brown podzolic soils (Luvisols). The results of mycoiogical studies indicate significant differences between soil fungi communities in both oak-hornbeam forests, although similarities especially in species composition of 15 of the most abundant fungi species were also found. The differences are the result of changes in the floral composition of degenerated oak-hornbeam forest. In the past, when typical oak-hornbeam forest covered whole studied areas, the soil fungi communities were probably almost the same in both plots. The first change could have happened after the removal of the trees; the second, after the re-afforestation of the resulting vacant area with pines. The re-appearance of Tilio-Carpinetum typicum in its once occupied habitat causes changes in the soil fungi community in the degenerated oak-hornbeam forest.

    Opis:
    In order to estimate sorption properties of gypsic rendzinas from the Niecka Nidziańska area as well as compare a composition of exchangeable cations in arable and turf soils 24 profiles have been investigated which represented following subtypes: initial, proper, chernozemic and brown ones, and derived from 3 types of miocene gypsum: selenite, shaly and compact gypsum. On the basis of the investigations it has been found that sorption properties of gypsic rendzinas were formed under influence of lithological factor and depend on the activity of the parent rock which is expressed by a content of the active calcium in the rock. Humous horizons of the arable soils characterised of a slightly lower complex exchange capacity and a higher contribution of potassium and magnesium in the composition of exchangeable ions in comparison with analogous horizons of the turf soils. A content of exchangeable cations permitted to count investigated soils among the soils with saturated complex of exchangeable cations. In their complex dominated calcium and the contribution of acid cations was small.
