Opis:
The aim of the study was to determine differences in the morphology, classification and chemical properties of soils in the city of Szczecin that have been anthropogenically transformed due to their location in an urban area. Soil samples were collected from 22 drillings, with depths of up to 200 cm, in both the Old Town and some newer parts of the city. Various properties were analyzed: the texture, pH in KCl, EC, base cations, and the organic carbon content, as well as the total content of Pb, Zn, Hg, Cd, Cu, Cr, Ni, and Hg. The soils in the Old Town of Szczecin exhibited the most significant anthropogenic transformation, containing anthropogenic admixtures and organic carbon throughout their profiles. These soils were classified as Urbic Technosols (Hyperartefactic) and Skeletic Phaeozems (Technic). The presence of numerous artefacts led to alkalization, high values of the base cations, elevated salinity, and increased content of certain heavy metals. The amounts of Zn, Hg, and Cu in these soils were approximately twice as high, and the Pb levels were seven times higher as the standards allowed by Polish law. Metal pollution in the Old Town area extended to a depth of 200 cm. The soils in the newer areas of Szczecin, which underwent less anthropogenic transformation, contained small amounts of anthropogenic admixtures up to a depth of 45 cm, which is why they did not classify as Technosols. As a result, they were less saline and alkalized, with lower base cations values. Organic carbon was present in these soils to a depth of 60 cm. Pollution with Pb, Cd, and Zn occurred only to a depth of 30 cm, indicating the contemporary origin of these pollutants. When new trees are planted in the Old Town area, consideration should be given to the species of trees that tolerate increased salinity. In newer areas of Szczecin, where salinity is low, all species of trees can be grown.

post-bog soils evolution
Opis:
This research presents the characteristics and inferred evolution of post-bog soils developed in the Last Glacial Maximum area of northwestern Poland near the southern Baltic coast. The study involved a total of five sites near existing lakes in NW Poland. In total, 21 soil pits were described and sampled and 17 piezometers were installed. In soil samples chemical and physical properties were determined. During the hydrological year the water level was checked and chemical properties of water were determined, the floristic composition at each location was also carried out. Mineralisation of post-bog soils initiated by dehydration leads to the decomposition of organic surface layers and an increase in CaCO3 content as well as mineral non-lime components at the expense of organic matter. A sequence of five soil types occurs in this landscape: Sapric Histosols (Limnic), Drainic Histosols (Calcaric, Limnic), Histic Gleysols (Murshic), Umbric Gleysols (Hyperhumic), Gleyic Phaeozems (Hyperhumic) that represent individual stages of soil genesis. Differences between the chemical properties of soils are apparent between organic vs organic-mineral and mineral layers. Man-induced drainage of post-bog soils changes their physical parameters. Bulk density increase and water retention decrease. The fluctuation of groundwater determines the moisture content of post-bog soils and affects the species composition of vegetation. Chemistry of groundwater is shaped mainly by the construction of catchment and the nature of its use, however, it is modified as a result of the inflow of macronutrients released during organic matter mineralisation processes and leaching of exchangeable forms from the sorption complex.

Opis:
Zinc is an essential microelement that is required for the proper growth and development of crops, and its content in the soil varies. Due to the physiological functions it performs in living organisms, zinc is considered an essential element in the nutrition of plants and animals. The total forms of trace elements do not fully reflect the possibilities of their absorption. They provide only approximate ranges of the soil’s abundance in a given ingredient. Plants can obtain microelements only from bioavailable forms.The content of available forms of elements in soils is one of the important determinants of plant yield. Zinc deficiency is a serious problem in agricultural soils around the world because it results in reduced crop yields. The aim of the study was to assess the content of total and available forms of zinc in the surface horizons of arable Luvisols in the Pałuki region, that has been intensively used for agriculture. Basic physical and chemical soil properties were determined using methods commonly applied by soil science laboratories. The content of total zinc forms was determined using the Crock and Severson method. Forms bioavailable to plants were identified using the Lindsay and Norvell method. The content of both forms of zinc was determined by atomic adsorption spectroscopy (AAS). In the analysed samples of arable land, low contents of total and available forms of zinc were recorded. The correlation analysis that was carried out confirmed that the content of these forms in the soil is significantly influenced by reaction. Due to the low levels of zinc forms found in the studied agricultural soils, It is necessary to monitor the amounts of this trace element.
Cynk jest mikroelementem niezbędnym do prawidłowego wzrostu i rozwoju roślin uprawnych, a jego zawartość w glebie jest zróżnicowana. Ze względu na funkcje fizjologiczne, jakie pełni w organizmach żywych, cynk uznawany jest za pierwiastek niezbędny w żywieniu roślin i zwierząt. Formy całkowite pierwiastków śladowych nie odzwierciedlają w pełni możliwości ich wchłaniania. Podają jedynie przybliżone zakresy zasobności gleby w dany składnik. Rośliny mogą pozyskiwać mikroelementy jedynie z form biodostępnych. Zawartość przyswajalnych form pierwiastków w glebie jest jednym z ważnych czynników warunkujących plonowanie roślin. Niedobór cynku jest poważnym problemem w glebach rolniczych na całym świecie, ponieważ powoduje zmniejszenie plonów. Celem badań była ocena zawartości form całkowitych i przyswajalnych cynku w poziomach powierzchniowych uprawnych gleb płowych regionu Pałuk, który od dziesięcioleci jest intensywnie użytkowany rolniczo. Podstawowe właściwości fizyczne i chemiczne gleby określono metodami powszechnie stosowanymi w laboratoriach gleboznawczych. Zawartość form cynku całkowitego oznaczono metodą Crocka i Seversona, a formy biodostępne dla roślin metodą Lindsaya i Norvella. Zawartość obu form cynku oznaczono metodą atomowej spektroskopii adsorpcyjnej (AAS). W analizowanych próbach gruntów ornych stwierdzono niską zawartość form całkowitych i przyswajalnych cynku. Przeprowadzona analiza korelacji potwierdziła, że na zawartość tych form w glebie istotny wpływ ma odczyn. Ze względu na niską zawartość form cynku w badanych glebach rolniczych, konieczne jest monitorowanie ilości tego mikroelementu.

Opis:
Petroleum products influence the engineering behaviour of the soil. Neogene clays and glacial tills from Central Poland were tested under laboratory conditions to evaluate the changes of selected physical and mechanical parameters: particle size distribution, particle density, swelling, shear strength and permeability. Four petroleum products were used in the experiments: diesel fuel, kerosene, jet fuel and mineral engine oil. The study revealed that even for the lowest degree of contamination the values of physical and mechanical properties of the soils changed significantly. Greater variation can be expected in soils contaminated with high-viscosity compounds. Also, higher relative changes were found for glacial tills than for Neogene clays. Consolidation tests revealed changes in soil permeability depending on the soil composition and the physical properties of the contaminant – considerable reduction of permeability was observed for glacial tills contaminated with light Jet fuel, while the reduction was lower for Neogene clays. The obtained results indicate the role of mesopores and the dimensionless pore pressure coefficient in changes of soil permeability. The methodological issues regarding testing and analysing the hydrocarbon-contaminated soils were also presented and discussed, which might be useful for researchers studying contaminated soils.

Opis:
Engineering activity may lead to uncontrolled changes in the geological environment. This paper presents an example of structural changes in fluvial sand of the Praski terrace (in Warsaw) caused by the activity of a temporary concrete batching plant. Our investigations made it possible to identify the material responsible for the structural anomalies observed in the bottom of the trench excavation. The compound responsible for the cementation phenomenon was identified as ettringite – hydrated calcium aluminosulphate: Ca6Al2[(OH)12(SO4)3]·26H2O. The source of ettringite were most probably significant volumes of contaminants coming from the temporary concrete batching plant (e.g., from the rinsing of concrete mixers and/or installations for concrete storage and transportation). While penetrating into the ground, ettringite caused extensive cementation of the soil mass, mainly in the saturation zone. As a result, the mineral (chemical) composition of the inter-grain space changed and the structure of the sand was strengthened. The estimated zone of volumetric changes in soil properties was about 6 thousand m3. However, analysis of the chemical composition of groundwater for its potential sulphate contamination, did not reveal any anomalous concentrations of sulphates.

Opis:
The studied bogs of the Siedlce Heights in eastern Poland are currently undergoing decession. In the course of pedological studies, a significant modification of the structure of soil profiles caused by the murshing process was found. The total contents of carbon and nitrogen values (TC/TN = 11.1–17.3) obtained in the study, as well as slight acidification (pHKCl 5.42–6.15) indicate the eutrophy of the studied soil environment, high biological activity and a significant degree of organic matter processing as a result of the processes of mineralization and humification. In addition, the upper levels covered by the process of murshing, compared to peat, are characterized by lower carbon content and, most often, similar nitrogen content. In the studied soils, humic substances are mostly represented by the fraction of humic acids. As a consequence, high values of the quotient expressing quantitative relations between soil humus fractions (HAs/FAs) were noted. For all profiles, the highest share of fulvic acids was recorded in turf murshic levels (M1). The occurrence of the most mature humic acids was found in the peat levels not covered by secondary transformation processes after dehydration.

The aim of the study was to recognise the accumulation of organic carbon (SOC) in the soils of Polish grasslands (GL) and to consider the possibility of increasing its sequestration in these soils. The Tiurin method (mineral soils) and the mass loss method (soil of organic origin) were used. It was found that: (i) the average SOC content of mineral soils is 2.44% and of organic soils - 10.42%; (ii) according to the Polish criteria, approximately 84% of GL mineral soils are classified as classes with high and very high SOC content, and over 15% and 1% - in classes with medium and low SOC content, respectively; more than 99% of organic soils belong to two classes with the highest SOC content and less than 1% to the class with an average content; (iii) according to the European Soil Bureau, the share of GL mineral soils with a high SOC content is slightly over 4%, medium - slightly over 47%, and low and very low - around 50%; for organic soils they are 67, 29, and 4%, respectively; (iv) the reserves of organic carbon in the 0-30 cm layer on the entire surface of GL soils amount to 412.7 Tg of SOC. There is considerable scope for increasing the SOC stock in meadow-pasture soils.

Opis:
The research was carried out in the morainic areas and in river valleys in NE Poland, where seven sites located in the macroregion of Masurian Lakeland were selected. Thirteen soil profiles representing the following organic soils were studied: earth-covered murshic soils (OMnm), murshic peat soils (OTmu), hemic murshic soils (OMhe) and sapric murshic soils (OMsa). The aim of the research was to investigate the content of selected macro- and microelements in surface formations of organic soils and to determine the influence of sedimentation processes on their spatial distribution. In terms of quantity, the analyzed macro- and microelements can be arranged as follows: Ca > Al > Fe > K > Mg > Na > P > Mn > Zn > Pb > Cr > Ni > Cu > Co. Organic soils situated in the depressions had various degrees of silting with mineral sediments from the nearby areas. Along with erosive waters, deluvial material rich in minerals was flowing along the morainic slopes. Therefore, mineral-organic formations (AO) located in the ecotone zone between mineral and organic soils had the highest content of total Mg – 4.85 g kg-1, K – 5.94 g kg-1, Al – 24.87 g kg-1, Fe – 17.77 g kg-1, Zn – 0.066 g kg-1, Cr – 0.046 g kg-1, Ni – 0.025 g kg-1, Pb – 0.060 g kg-1. The highest content of total calcium, manganese, iron, copper and cobalt was found in mineral-organic formations (AO) and strongly silted murshes (Mtsz). The contents of calcium and sodium were significantly positively and the contents of other macro- and microelements were significantly negatively correlated with the amount of organic matter, organic carbon and total nitrogen.

Opis:
Azotobacter spp. are soil bacteria capable of fixing atmospheric nitrogen and making it available to plants. This makes them microorganisms of hight importance to the agriculture. The distribution of these bacteria is a complicated subject and is correlated with diverse factors, witch determine the presence or absence of the bacteria in a specific soil. The soil properties as soil and fertility and climate conditions affect the abundance of diazotrophs. Research material consisted of 182 soil samples taken in 2015 from agricultural land in various voivodeships. The number of Azotobacter spp. was determined based on plate method. The presented study evaluated the abundance of Azotobacter spp. in various Polish soils and confirmed the relationship between soil properties and the presence of these bacteria. The studied bacteria were present in 37% of soil samples and numbers of these bacteria varied widely, from 3 to 10801 cfu g-1 of the soil. In the case of Azotobacter spp., soil acidity was also an important factor restricting the occurrence of these bacteria in soils.

Opis:
The purpose of this study was to estimate nitrogen oxide emissions from soils used for agricultural purposes by voivodships. Compared N2O emissions were estimated according to the recommended IPCC (tier 1) method with simulated emissions using the DNDC (tier 3) model. Analyses were done for crop rotation (winter rape, winter wheat, winter wheat, winter triticale) in four cropping systems. Moreover, simulated N2O emissions from winter rape and winter triticale cultivation showed lower emissions and constituted 1475% and 13-76% of IPCC estimated emissions, respectively. The use of the model also enabled the determination of factors, which have an impact on nitrous oxide emissions and define its regional differentiation. The analysis showed that with increasing initial soil organic content, emissions of N2O rise and decrease with increasing precipitation or carbon sequestration. Considering the requirements for reduction GHG emissions, improving the methodology used in estimating nitrous oxide emissions is of significant practical value.
Celem badań było oszacowanie wielkości emisji podtlenku azotu z rolniczego użytkowania gleb w przekroju województw. Porównano wielkości emisji N2O oszacowane według zalecanej metodyki IPCC (tier 1) z emisjami symulowanymi, z wykorzystaniem modelu DNDC (tier 3). Symulacje były przeprowadzone dla zmianowania upraw (rzepak ozimy, pszenica ozima, pszenica ozima, pszenżyto ozime) w czterech systemach uprawy. Model DNDC wykazał, że emisje podtlenku azotu z uprawy pszenicy ozimej stanowiły 9-46% emisji szacowanych metodą IPCC. Również symulowane emisje N2O z uprawy rzepaku ozimego i pszenżyta były zdecydowanie niższe i mieściły się w przedziale odpowiednio: 1475% oraz 13-76% emisji szacowanych według IPCC. Zastosowanie modelu pozwoliło także na określenie, które czynniki wpływają na wielkość emisji podtlenku azotu i decydują o jej regionalnym zróżnicowaniu. Przeprowadzona analiza wykazała, że emisje N2O zwiększają się wraz ze wzrostem początkowej zawartości materii organicznej, zmniejszają się zaś ze wzrostem opadów lub sekwestracji węgla. Dlatego, uwzględniając wymagania w zakresie ograniczania emisji gazów cieplarnianych, doskonalenie metodyki szacowania emisji podtlenku azotu ma istotne znaczenie utylitarne.
