Opis:
In the result of geomechanical transformations associated with the activity of open cast brown coal mining, some changes in air-water relations may occur on arable land adjacent to these regions usually referred to as hvdrological alterations. However, they do not always need to result in soil degradation, i.e. in the deterioration of their production potentials. This will often depend on the distance of fields from the workings, value of the arable land (soil quality class), type of water management, etc. On the basis of long-term studies carried out in the area of operation of two brown coal mines - KWB "Konin" and "Adamów" - on arable land and grasslands of over 60 villages on the total area of 30 thousand hectares it was possible to develop evaluation criteria for the extent of soil degradation and work out principles for compensation payments for farmers. Three zones and appropriate sub-zones of soil susceptibility to drainage were determined and clear and simple criteria for the estimation of the extent of arable land and grassland degradation were worked out. Furthermore, the authors proposed simple and readable systems to calculate compensatory payments to be paid to farmers taking into account the state of soil degradation, value of agricultural land (price of 1 ha of land of appropriate class) and the area of damaged land. The degree of soil degradation, both of arable land and grasslands, ranged from 10 to 30%. In the case of grasslands, additionally, an appropriate sum of money was allocated to compensate for sward recultivation.

The content of Cd, Pb, Cu, Ni and Cr was analysed in the soil layers of 0-20 and 21-40 cm originating from four fruit growing farms localised in the area of Wielkopolska. The analyses have shown that the content of all the investigated heavy metals both in the arable soil layer and in the subsoil, was lower than their natural content in the Polish soils. The phenomenon of decreasing Cd, Cu and Pb content, and increasing Ni values in the deeper soil layers as compared to the arable layer was observed.

Opis:
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.

In July 2000 the diurnal cycle of analyses was conducted in order to determine variation in the concentrations of nitrogen and calcium compounds as well as dissolved gases in surface microlayers of a shallow coastal barrier lake located at the Baltic Sea coast. Water for analyses was collected in a diurnal cycle for the period of 24 h from lake Dołgie Wielkie. The analyses were conducted on the surface microlayer with a thickness of approx. 100 μm, a layer with a thickness of approx. 250 6m and a layer of subsurface water from a depth of 15 cm. Based on the analyzed data, information was collected on the migration of nitrogen compounds between the analyzed layers. Changes were observed in nitrogen forms reduced to oxidized forms and vice versa.

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:
A static field experiment carried out on lignite discard, manure and mineral fertilisers in the years 1994 to 1998 was used to study effects on yield and sonie soil chemical properties of the applied variants of organic and mineral fertilisation: NPK; manure 30 t/ha + NPK; lignite discard 90 t/ha; lignite discard 90 t/ha + NPK. The present results show that lignite discard contributed to an increase of yield production potential of a good rye complex soil and brought about a significant increase of the triticale grain yield in comparison with the object with manure. The level of mineral fertilisation applied in the entire crop rotation, in relation to various variants of organic fertilisation (which was applied 3, 2 and 1 year before the examination) exerted a positive effect on pH and the content of basic nutrients in the soil.

Opis:
Research carried out on mineral soil with mechanically damaged upper layer proved greater variability of general aspect between species than between varieties within a species. Among the investigated species, the following had higher general aspect values during the whole research period: Festuca ovina, Festuca rubra, and Lolium perenne; while Agrostis capillaris and Agrostis canina had lower values. Significant differentiation of the general aspect evaluations were observed only in Festuca genera variations, whereas evaluations of the general aspect of variations within the rest of the species were close. Sowing time did not significantly affect di fferentiation in the evaluation of the general aspect of varieties in Agrostis, Poa, and Lolium genera. However, spring sowing positively affected the general aspect of the Festuca ovina varieties and the Terros variety (F. arundinacea).

Opis:
Indigenous mycorrhizal colonisation of one (1/0) and two (2/0) year old Scots pine (Pinus sylvestris L.) seedlings from forest nurseries situated in the north-west part of Poland was investigated. Seedlings were fertilized after a schedule designed to satisfy their requirements which resulted from soil analysis of each nursery. In autumn needle nitrogen concentration and mycorrhizal status were estimated. As a rule seedlings 1/0 obtained high doses of fertilizers, and their needle nitrogen concentration highly exceeded the recommended optimal level above which mycorrhiza formation is greatly restricted. Highly negative correlation was found between the nitrogen status of foliage and mycorrhizal quantitative and qualitative colonisation estimated in the abundance class of 0-5. When internal nitrogen level was low, several ectomycorrhizal morphotypes were found on roots of tested plants. Excessive nitrogen fertilization decreased root ramification pattern and along with increased pH promoted ectendomycorrhizal symbiosis. Two-year-old seedlings (2/0) were characterised by significantly lower nitrogen concentration in the needles which resulted in much higher ectomycorrhizal colonisation. Ectendomycorrhizal symbiosis in the case of 2/0 seedlings was scarce. The results indicate that natural colonisation in nurseries is dependent on the soil management practices, especially nitrogen fertilization. Optimalization of nitrogen fertilization may intensify ectomycorrhizal colonisation of the nursery stock from indigenous fungal species and improve the growth of Scots pine seedlings in bare-root nurseries and plantations.

Opis:
The aim of the study was to analyse the balance of mercury (Hg), i.e. the content of this metal, its inflow and outflow, in the ecosystem of the Bay of Puck. Based on literature data and the results of the author’s own study, this analysis has shown that the main source of Hg pollution is the atmosphere. An estimated 1.1–3.8 kg of Hg enters annually from the atmosphere, whereas the mass of Hg carried there by river waters per annum is about 7 times lower (0.13–0.44 kg year−1). The 0.9 –2.7 kg year−1 of Hg released from Bay of Puck waters to the atmosphere is of the same order as the quantity deposited from the atmosphere. The total amount of Hg deposited in the upper (0–5 cm deep) layer of the sediments has been estimated at 240–320 kg, its rate of entry being c. 2.25–2.81 kg year−1. 0.25–1.25 kg year−1 of Hg are released from the bottom sediments to bulk water, while 0.61–0.97 kg remains confined in aquatic organisms, including 133 g in the phytobenthos, 2.6 g in the zooplankton, 420–781 g in the macrozoobenthos and 34 g in fish.

Opis:
Ecosystem services (ES) concept has been popular among researchers in the last several years. In this paper, we assessed the development and trends in Polish ES research in the period 2010-2016 using the content analysis of 84 scientific papers – the outcome of ECOSERV Symposia. We analysed such attributes as the type, dimension and scale of the study, ecosystems and ES investigated, the system used to name or classify ES, data used, as well as the considered policy and business questions. In addition, we compared the Polish studies with the European research in the database developed in the ESMERALDA project. The conducted study provides insight into the major achievements as well as challenges that the Polish ES research community will have to face. The findings may serve a discussion on how future directions of the research can be shaped in order to mainstream ES into environmental management.
