    Opis:
    The paper presents the possibility of applying spent synthetic ion exchangers and sorbents based on natural zeolites for the reclamation of degraded soils. The obtained research results confirmed the improvement of the soil sorption capacity (cation exchange capacity) caused by the addition of spent ion exchange sorbents. They also enabled to determine the magnitude of changes of the analyzed parameters depending on the amount of wastes introduced to the soil. The addition of 1% (w/w) spent cation exchanger enables to increase the cation exchange capacity twice, whereas in the case of zeolite, the observed increase reaches about 20%. Simultaneously, introduction of waste ion exchange sorbents increases the content of exchangeable calcium and magnesium while doubling in the content of these macroelements is observed for 5% (w/w) and 2% (w/w) of spent ion exchanger, respectively. In the case of the exchangeable potassium content, a satisfactory increase is observed with 1% (w/w) addition of spent zeolite.

    Opis:
    The number and groups of mites (Acari) and species composition of oribatid mites (Oribatida) were analysed in three different substrates used for the restoration of degraded soils: (1) pine forest litter, (2) apple orchard litter, and (3) pine chips. The study was conducted in the years 2011-2012, on microplots of the area of 1m2 , established in a belt of trees of a nursery in Białe Błota (Bydgoszcz Forest District). Average biannual mite density per 50 cm3 of the investigated substrates ranged from 14.6 to 54.43 individuals. The highest numbers of mites were found in shredded forest litter and the lowest in pine chips. The most abundant mites in the studied material were oribatid mites, accounting for 57.3 % of these arthropods. The highest number of oribatid mites was found in the forest litter (28), and the lowest (20) in pine chips. The number of species in both types of litter was similar in the first and second year of the study, but it rose three times in the pine chips substrate over the study period. Oribatid species in the litter substrates were dominated by the eurytopic Tectocepheus velatus, and the most abundant species in the pine chips substrate was Oribatula tibialis. The experiment indicated a possibility of practical use of the shredded litter in the reintroduction of soil mesofauna and soil regeneration. This may facilitate the soil inoculation process, e.g., by using seeders specially adapted for this purpose. Additionally, a quick colonization of wood chips by acarofauna may suggest the possibility of using them as an excellent substrate for soil regeneration.

    Opis:
    The efficient use of water is increasingly important and proper soil management, within the specificities of each region of the country, allows achieving greater efficiency. The South and Caparaó regions of Espírito Santo, Brazil are characterized by relief of ‘hill seas’ with differences in the degree of pasture degradation due to sun exposure. The objective of this study was to evaluate the least limiting water range in Udox soil under degraded pastures with two faces of exposure to the sun and three pedoenvironments. In each pedoenvironment, namely Alegre, Celina, and Café, two areas were selected, one with exposure on the North/West face and the other on the South/East face. In each of these areas, undisturbed soil samples were collected at 0-10 cm depth to determine the least limiting water range. The exposed face of the pasture that received the highest solar incidence (North/West) presented the lowest values in least limiting water range. The least limiting water range proved to be a physical quality indicator for Udox soil under degraded pastures.

    Opis:
    Gleby zdegradowane w wyniku szkodliwego oddziaływania emisji z hut metali nieżelaznych są często wyjałowione z substancji organicznej oraz brak w nich odpowiedniej mikroflory. Taki stan środowiska glebowego wyklucza skuteczność biologicznej rewitalizacji bez wcześniejszego wzbogacenia matrycy gleby odpowiednimi substratami. W pracy przedstawiono wyniki badań dotyczące zmian wartości wybranych parametrów mikrobiologicznych i fizyczno-chemicznych gleby wzbogaconej komunalnymi osadami ściekowymi po 6 miesiącach od aplikacji substratu. W doświadczeniu wykorzystano zdegradowaną glebę pochodzącą z terenu oddziaływania huty w Miasteczku Śląskim i komunalny osad ściekowy z oczyszczalni ścieków komunalnych w Pajęcznie w trzech proporcjach wagowych (10, 30 i 50%). Przeprowadzone analizy wykazały poprawę większości badanych parametrów (pH, TEB, CEC, azot organiczny, fosfor przyswajalny, liczebność grzybów i promieniowców), a zastosowane osady ściekowe przyczyniły się zarówno do wzrostu zdolności buforowych badanej gleby, jak i jej znacznego wzbogacenia w fosfor przyswajalny łącznie z poprawą stosunku C:N. Otrzymane dane wskazują, że w badanej glebie zachodzi korzystna odnowa procesów mineralizacji substancji organicznej, co potwierdza skuteczność stosowania osadów ściekowych w rekultywacji gleb zdegradowanych.
    One of the most widespread form of soil degradation is the chemical contamination, which is generally seen in industrialized areas and can be manifested as heavy metals pollution. Soils degraded by the toxic emissions from non-ferrous foundries (rich of heavy metals) are very often deficient in organic compounds and suitable microflora because of limited soil's protective abilities in the presence of metallic elements contamination. That kind of soils is hard to revitalize without earlier improvement of soil matrix by specific substratum. Sludges from municipal waste water treatment plants (particularly from country-side ones) are rich in nutritive compounds which can be assimilated by plants. Because of that, sludges can be very effective soil-forming substrates in upper layers of inorganic ground where they can restore a biological activity which is proper for fertile soils. The paper presents the evaluation of municipal sewage sludge influence on selected physico-chemical and biological (bacteria and fungi constitute the most important part of the microflora present in soils) parameters of degraded soil after six months since the application. The investigated soil was taken from the area polluted by Miasteczko Slaskie zinc foundry, and municipal sewage sludge originated from waste water treatment plant in Pajeczno. Conducted analyses have shown improvement in the majority of studied parameters (fungi and actinomycetes population, pH, TEB, CEC, Kiejdahl's nitrogen and assimilable phosphorus). Applied sewage sludge caused improvement of sorption capacity (cation exchange capacity - CEC) which indicates amelioration of soil's fertility. Sludge used in experiment also indicates high enlargement of assimilable phosphorus in connection to appropriate carbon to nitrogen ratio (C:N). The presented work has shown positive sewage sludge influence on organic matter mineralization processes which confirms the fact that this substratum can be effectively used in degraded soil reclamation e.g. in low cost soil cleaning procedures like phytoremediation.

    Opis:
    The aim of the experiment was to compare the rehabilitating effect of three factors that may improve the degraded and very poor soils formed from loose sands: dolomite liming, use of a multi−component fertilizer with delayed action (Silvamix W) and temporary introduction of an admixture Alnus incana into the Pinus sylvestris plantation. The results of the factorial experiment after 9 years indicate that the soils on which the experiment was established cannot be afforested without prior rehabilitation treatments. The activity of dolomite was most effective while of Silvamix − weaker. Alder survived in the plantation composition only when used in combination with dolomite fertilization, then its rehabilitating effect was apparent. Rehabilitation relying on the use of dolomite at a rate of 2 t/ha in combination with a 50% admixture of alder in the pine plantation is recommended to be used in practice.

    Opis:
    The aim of this study was to compare colonization of pine chips without supplements and pine chips supplemented with forest litter, peat and lignite by mites (Acari), and particularly oribatid mites (Oribatida) in a two-year cycle. The study was conducted in the years 2013-2014, on microplots established in a belt of trees in a nursery in Białe Błota within Bydgoszcz Forest District. The experiment was established on four microplots (1 x 1 m). It included the following variants: C - pine chips alone, Lf – pine chips inoculated with fresh forest litter, Lf+Pe – pine chips enriched with deacidified high peat (20%) (pH 5.5-6.5) and inoculated with the litter, Lf+Li - pine chips enriched with granulated lignite (20%) inoculated with the litter. In the first year of the study, mite abundance in the chips inoculated with forest litter was significantly higher than that on microplot C. In the second year of the experiment, the abundance of these microarthropods decreased probably due to unfavorable weather conditions. The most common group of mites were usually oribatid mites that accounted for 19.7 to 80.4% of all mites. An analysis of seasonal dynamics of Oribatida abundance over the entire study cycle revealed a clear increase in their numbers in non-supplemented pine chips only on the last sampling date. Oribatida abundance in Lf variant was similar at the beginning and end of the study. Contrary to that, their number decreased in the chips supplemented with peat, and particularly those enriched with lignite. In total, 36 species of oribatid mites were identified on all microplots. The greatest boost in species diversity after the introduction of forest litter was observed in Lf chips and the smallest in Lf + Li variant. Oribatula tibialis was the most common oribatid mite in the investigated substrates. Low numbers of Oppiella nova and Tectocepheus velatus, the species having trophic associations with fungi, may indicate poor colonization of the chips, particularly those enriched with lignite, by saprotrophic organisms.

    Opis:
    Concentration and profile distribution of heavy metals was investigated as contamination indicators of the forest soils formed from glacial deposits of the South Podlasie Lowland. The study was carried out on thirteen soil profiles situated a hundred meters from the road. The highest content of heavy metals was found in the organic horizons of the investigated soils. The mean content of Mn, Zn, Cu, Pb, Ni, Cr in the investigated soils were: 556.7, 72.9,15.5, 63.5,13.8, 16.5 mg/kg d.m. of the soil, respectively. In the mineral-organic and mineral horizons of the investigated soils heavy metals were present in quantities which were close to natural. The podzol soils, podzols and rusty soils developed from sands contain less heavy metals than the soils lessivés, black earth and deluvial soil. The Mn, Zn, Cu, Pb distribution in the soil profiles is influenced by the soil forming processes. The distribution index of the examined metals distribution in the genetic horizons testify to it.

    In the study, the content of heavy metals such as Pb, Cd, Ni, Cu, Zn and Mn in the soils collected from various regions of the Lublin Voivodeship was examined. The examined soils were light medium soils. Content of individual elements was determined by the AAS method in the extracts of 1 M HCl. The analysed soils were poor in copper and manganese. Their concentration and the concentration of lead, cadmium and nickel was in the lower realms of the range natural for light soils formed from sands. Only the content of zinc was fairly high in the above soils, frequently as high as the first degree of contamination.

The studies comprised 20 points in the vicinity of Sosnowiec and 20 points from near Zawiercie. Soil abundance in the available forms of microelements was assessed on the basis of the limiting numbers suggested by the Institute of Soil Science and Plant Cultivation. Soils of Zawiercie and Sosnowiec belonged to those with high contents of zinc in all the cases; in the majority of objects these were the soils with medium contents of copper and manganese. In half of the cases, the soils were classified as possessing low iron content, and in the remaining half as having medium iron content.

    The paper characterises total concentrations of Cd, Cu, Ni, Pb, Zn in the surface layers (0-20 cm) of agricultural soils in Poland (48620 soils samples) and Lublin region (3829 soil samples). The results for Lublin region are expressed in terms of the degree of metal pollution as compared to contamination in the rest of the country. The average concentration of Cd, Cu, Ni, Pb and Zn (in mg kg-1 of soil) in the A horizon of agricultural soils in Poland and in Lublin region (values in parenthesis) are as follows: 0.21 (0.17); 6.5 (4.9); 6.2 (6.6); 13.6 (10.7); 32.4 (23.3). About 79% of the agricultural soils in Poland are characterised by a natural (0°) content of heavy metals while 17.6% contain elevated level (10) of these metals. In the Lublin region it is 91.9% and 6.7%, respectively. About 3% of the Polish soils (1.4% in the Lublin region) exhibit various degrees of contamination with heavy metals. This includes heavy (IV0) and very heavy pollution (V0) which is found in up to 0.4% of the agricultural land and up to 0.2% in the Lublin region.

    The studies comprised 20 points localised in four communities of the Silesian province The aim of the investigations was to assess cadmium contents in soils, grain and straw of spring barley cultivated in the ecologically hazardous region and to describe relations between this metal contents in the soils and indicative parts of barley. It was found out that 27 of the examined soils were characterised by an increased cadmium contents, 69 of the soils were slightly contaminated and 8 of them showed medium contamination. In 42 grain samples of barley the permissible dose was exceed in the plants appropriated for consumption. A significant relationship was found between cadmium contents in the soils and their granulometric composition. Significant relationships were also registered between cadmium concentration in the soil and its contents in barley. Cadmium contents in grain was significantly correlated with organic carbon and clay fraction. However for straw, significant relations were found between cadmium contents and granulometric composition, reaction and organic matter contents.

    Opis:
    The present paper reviews content and phytoavailability of heavy metals (Cd, Cu, Ni, Pb, Zn) in the soils of seven selected regions in the former Tarnów province, considered to be particularly endangered by contamination by these metals. One hundred soil samples were collected, 50 from the 0-10 cm layer and 50 from the 40-50 cm layer and mixed meadow sward from the same places. Most of the examined soil samples had a natural heavy metal content with the exception of a few samples containing higher amounts of Cd, Ni, and Zn. A strong correlation between heavy metal content and soil sorptive capacity and the organic matter content and the level of soil fraction with particle diameter of <0.02 and <0.002 mm was observed. Analysis of heavy metals in plants revealed that the limit values of Cd and Zn content were exceeded only occasionally together with reduced fodder quality of the investigated sward.

    Opis:
    The alluvial soils in the Bóbr river valley, devastated by sand and gravel exploitation, were reclaimed for agricultural use. After reclamation treatment, the newly formed soil was very acid. Application of 5 Mg/ha lime elevated soil pH to 6-7, but during the following years, soil pH dropped again by about one half of the pH unit a year. Rapid drop in the pH level can result both from geological and soil-forming processes. Efficiency of mineral fertilizers applied in various combinations did not give the expected results and the yield of cultivated plants was not satisfactory. Mineral fertilization in various combinations did not result in the expected yield levels.

    Opis:
    Research was carried out on the basis of investigations from the years 1996-1998 on the so-called monoliths in the soils derived from loess formations. Properties of those formations were differentiated by landscape and processes of water erosion. It was found out that post-sewage waters (waters received after sewage treatment) from a mechanical-biological sewage treatment plant have a more favourable influence on both the value of acidification indexes and relations between cations in the soils than solid mineral salts.

    Opis:
    Lublin municipal waste water effluent treated in two stages (mechanical and biological) was used in the monoliths filled with loess soil of an undisturbed structure taken from different erosion zones: W - top (grey-brown podzolic soil): D - bottom of the valley (deluvial soil); N - northern slope (brown soil - weakly eroded), S - southern slope (calcareous soil - strongly eroded). Control objects were the monoliths treated with equal amounts of water and nutrients: N, P, K, Mg. In the soils treated with sewage and water and mineral salts, a similar increase in the content of soluble metal forms (Zn, Cu, Mn, Pb, Cd, Ni) was observed.

    Opis:
    The aim of this paper was to assess differentiation in the total content of Cu, Zn and Mn under the influence of water erosion. The present author investigated parent material, eroded soils and delluvial sediments of a small arable-forest catchment of the moraine zone in West Pomerania. The average content of heavy metals in the parent rock (boulder light loam) were assumed as geochemical backgrounds of Cu, Zn and Mn. It was found out that erosion process caused differentiation in heavy metals. Zinc was the most mobile in this transportation; Mn was not sensitive to it. Delluvial sediments from arable (drainage) depressions had a clearly lower content of Cu and Zn than the parent material. It was also noted that Cu and Zn content in the forest area was lower than in the arable area of a similar relief and soil composition. Mn content was always higher in the arable soils. Soil-forming processes influenced differentiation of heavy metals in the vertical soil profile. The humus and Bt horizons (accumulation of silicate clay) were enriched with heavy metals. A decrease of heavy metal content was noticed in the eluvial horizon (Eet - outwash of silicate clay). The humus horizon of the investigated soil had, a natural (not increased) content of Cu, Zn and Mn.

    Opis:
    Results of mineral forms of nitrogen (N-NO3 and N-NH4) changes in ectohumus layers and needles during decomposition processes are presented. The experiment was conducted in controlled conditions in a chamber with stable temperature and humidity. Plant samples and soil samples from ectohumus were taken in ecosystems in various stages (object without damages signs, in the process of degradation and degraded). In the fresh material, directly after sampling, content of mineral forms of nitrogen was analyzed. Controlling of the content changes were done after 30, 60 and 90 days of incubation. In the fresh material high differences of the content of N-NO3 between degraded ecosystems were found. The lowest content were found in needles of degraded spruce forest and this situation was permanent during the incubation. In the Oh layer content of N-NO3 was initially the lowest, but during incubation was increasing and after 30 days of decomposition was the highest. The highest content of ammonia nitrogen was found in needles from degraded ecosystems and despite of decreasing the amount during decomposition this was stable until 90-1 day of incubation. In Oh layers content of N-NH) was decreasing with the time of incubation and the most clear was observed in ecosystems in degradation process and degraded as well.
    W pracy przedstawiono wyniki analiz zmian zawartości mineralnych form azotu (N-NO3 oraz N-NH3) w poziomach próchnic nadkładowych (Olf i Oh) oraz w igłach świerków podczas procesów ich dekompozycji. Doświadczenie prowadzono w warunkach zamkniętych w komorze inkubacyjnej, przy stałej temperaturze oraz wilgotności. Próbki materiału roślinnego - igły oraz próbki z poziomów próchnicy nakładowej pobrano z ekosystemów świerkowych w różnym stadium degradacji (obiekt bez objawów degradacji, zamierający oraz obumarły). W materiale świeżym, bezpośrednio po pobraniu w terenie wykonano oznaczenia zawartości form N-NO3 oraz N-NH4. Kontrolę zawartości mineralnych form azotu przeprowadzono po upływie 30, 60 i 90 dni inkubacji. W materiale wyjściowym wystąpiły znaczne różnice w zawartości form azotu azotanowego. Najmniejszą jego ilość stwierdzono w igłach świerków obumarłych i taka zawartość utrzymywała się przez cały okres inkubacji. W poziomie epihumusowym (Oh) zawartość N-NO3 była początkowo najmniejsza, spośród badanych obiektów, ale z upływem czasu inkubacji zwiększała się i od 30 dnia procesu dekompozycji utrzymywała się na najwyższym poziomie. Największą zawartość azotu amonowego odnotowano w igłach świerków obumarłych i mimo tendencji spadkowych we wszystkich obiektach, taki stan utrzymał się do 90 dnia inkubacji. W poziomach epihumusowych, niezależnie od stopnia degradacji siedliska, zawartość azotu amonowego zmniejszała się wraz z upływem czasu inkubacji, a najwyraźniej zmiany te zachodziły w siedliskach zamierających i obumarłych.

    Opis:
    The author investigated a 0-3 cm layer of two forest brown soils: brown acid and brown leached. These forest soils were under handsome beech trees (Fagus sp.) between 100 and 120 years old. The author compared the chemical properties of the soils. The soil existing near the tree trunk (1 m2 of surface, strongly washed by rain water polluted by chemical substances) and the soil existing under the tree umbrella (40 m2 of surface in the area of the tree-tops, washed poorly by rain water). This comparison showed changes in these properties, dependent upon the degree of atmospheric contamination. It was found that, at the same level of atmospheric contamination, higher changes of properties were found in brown leached soil than in brown acid soil. Less acidified soils (with alkaline or neutral pH reaction) are more suitable in these researches. The investigations of the forest soil layer 0-3 cm (12 soil profiles) showed that changes in their chemical properties in relation to tree trunk-tree umbrella can be the basis of assessment of the degree of atmospheric contamination.

    Opis:
    Przedstawiono tok postępowania w pracach rekultywacyjnych gleb i gruntów zdegradowanych chemicznie. Na podstawie uzyskanych danych z poligonu badawczego w Łomiankach wykazano konieczność dokonywania badań geochemicznych na terenach, gdzie istnieje chociażby niewielkie prawdopodobieństwo skażeń, określając metodykę badań, kryteria ocen i przykład rekultywacji. Sposób realizacji inwestycji uzależniono od szczegółowego rozpoznania stopnia degradacji podłoża i jego zasięgu przestrzennego w nawiązaniu do wykształcenia litologicznego warstw, warunków geologicznych i hydrogeologicznych oraz koncepcji rekultywacji.
    The article presents the course of action in reclamation works on chemical degradation of soils and grounds. On the basis of the data gathered from the test site, the need for geochemical analyses has been demonstrated in the areas of even a slight possibility of contamination. The methods of analyses, evaluation criteria, and example of reclamation have been specified. The way of executing the investment will depend on the detailed identification of the degree of the substrate degradation as well as its spatial extent in relation to the lithologic formation of layers, geological and hydrogeological conditions and the resulting concept of recultivation.
