The aim of the modeling studies (MONERIS) was to estimate annual source apportioned nitrogen (N) and phosphorus (P) emissions into the Vistula and Oder basins in 1995-2008, thus, during the transition period in Poland, characterized by changes in both agricultural sector and handling of point source pollution. N and P emissions into both basins showed declining tendencies. Between the sub-periods 1995-2002 and 2003-2008, the overall N emission into the Vistula and Oder basins decreased by 16-17% (i.e. by ca 26,900 tons in the Vistula and by ca 18,000 tons in the Oder basin); P emission declined by 23% in the Vistula and by 32% in the Oder basins (i.e. by ca 3400 tons in the Vistula and by ca 2200 tons in the Oder basin). The temporal patterns of N and P emission into the Vistula and Oder basins, as well as the percentage contribution of N and P pathways (particularly: overland flow, tile drainage, groundwater, waste water treatment plants) showed great differences between the basins. Natural (type of bedrock, soil type, lake area) and anthropogenic (regionally and temporarily different type and intensity of agricultural activity, spatially different structural changes in agriculture during the transition period, regionally and temporarily different investment in waste water treatment plans) factors were found to be responsible for the differences, and the relationships are extensively discussed in the paper. In 1995-2008, 70% of N emission into both river basins was via groundwater and tile drainage, with the former playing more important role in the Vistula basin, and the latter playing more important role in the Oder basin; contribution of N emission from point sources was comparable in both rivers and it reached 11-12%. In 1995-2008, point sources, erosion, overland flow, and urban systems were found the most important P pathways in both basins, with a higher percentage contribution of point sources in the Oder basin. © 2011 Elsevier B.V.

Metal (Zn, Pb, Cd, Cu, Ni, Cr) accumulation in shoots of 38 plant species spontaneously colonizing three Zn-Pb waste deposits in southern Poland was studied in order to find out if the age of the waste (30-130 years) or its type (slag or flotation residues) influence metal content in plants and to identify species potentially suitable for biomonitoring and phytoremediation. The total metal concentrations in the waste upper layers ranged from 7300 to 171790mgkg-1 for Zn, from 1390 to 22265mgkg-1 for Pb, and from 66 to 1464mgkg-1 for Cd, whereas CaCl2-extracted fractions accounted for 0.034-0.11 %, 0.005-0.03 %, and 0.28-0.62 % of total Zn, Pb and Cd concentrations, respectively. The concentrations of Cu, Ni, and Cr in substrates and in plants were low and ranged within the background values. Metal accumulation in plant shoots was poorly correlated with both total and CaCl2-extracted forms of metals in the substrate and was highly variable among species and also specimens of the same species. The highest mean concentrations of Zn, Pb and Cd were found in Anthyllis vulneraria L. (901.5mgkg-1), Echium vulgare L. (116.92mgkg-1), and Hieracium piloselloides Vill. (26.86mgkg-1), respectively. Besides Reseda lutea L., no species appeared to be a good indicator of polymetallic environment pollution based on chemical analysis of shoots; however, metal accumulation in the whole plant communities of a particular contaminated area might be an accurate tool for assessment of metal transfer to vegetation irrespective of the type or age of the waste. All the species studied developed a metal exclusion strategy, thus exhibiting potential for phytostabilization of metalliferous wastelands. © 2014 Elsevier B.V.

The plant hormone auxin is believed to influence almost every aspect of plant growth and development. Auxin transport, biosynthesis and degradation combine to form gradients of the hormone that influence a range of key developmental and environmental response processes. There is abundant genetic evidence for the existence of multiple pathways for auxin biosynthesis and degradation. The complexity of these pathways makes it difficult to obtain a clear picture of the relative importance of specific metabolic pathways during development. We have developed a sensitive mass spectrometry-based method to simultaneously profile the majority of known auxin precursors and conjugates/catabolites in small amounts of Arabidopsis tissue. The method includes a new derivatization technique for quantification of the most labile of the auxin precursors. We validated the method by profiling the auxin metabolome in root and shoot tissues from various Arabidopsis thaliana ecotypes and auxin over-producing mutant lines. Substantial differences were shown in metabolite patterns between the lines and tissues. We also found differences of several orders of magnitude in the abundance of auxin metabolites, potentially indicating the relative importance of these compounds in the maintenance of auxin levels and activity. The method that we have established will enable researchers to obtain a better understanding of the dynamics of auxin metabolism and activity during plant growth and development. © 2012 Blackwell Publishing Ltd.

This article presents a review of methodologies allowing for the calculation of agricultural biogas potentials on a regional level. A definition of theoretical, technical and economic potentials as well as methods for their calculation are provided. The review of the state-of-art studies in this area has indicated that despite differences in calculation methods, procedures for approximation of theoretical and technical potentials are well established. However, there have been various approaches to elaborate a methodology to calculate the economic (market) potential. In this article a scenario building approach is applied for a case study region of the Lubelskie Province, east of Poland. The results have shown that the elaborated methodology can be applied by policy makers to integrate also other renewables in planning procedures. © 2014 Elsevier Ltd.

The most cost-effective and pro-ecological method of purifying the environment moderately contaminated with heavy metals is the extraction of such substances from the soil by plants, which are able to grow under conditions of high concentrations of toxic metals and to accumulate them in their tissue. The 3-year microplot experiment with perennial energy crops, miscanthus (Miscanthus giganteus) and Virginia mallow (Sida hermaphrodita), was conducted in the Experimental Station of the Institute of Soil Science and Plant Cultivation in Puławy, Poland (51°25'N, 21°58'E). The experiment was carried out on two different soils with varying levels of acidity, moderately contaminated with zinc and lead. The results from the three first years of cultivation of these plants (2008-2010) indicate that miscanthus and Virginia mallow can be cultivated on soils, moderately contaminated with zinc and lead. Miscanthus turned out to be a more tolerant species. Its dry matter yield on average was two times higher and accumulated higher quantities of zinc and lead in biomass compared to Virginia mallow. Thus, the phytoextraction of Zn and Pb from the soil contaminated with metals was much greater for the miscanthus than for mallow, and significantly higher uptake of Zn than Pb was observed.

This study evaluated the interactions between antiradical and anti-inflammatory compounds from coffee and ginger. Results obtained for whole plant material extracts were compared with those for chlorogenic and caffeic acids (the main hydroxycinnamic acids of plant material). All the tested samples showed the ability to scavenge free radicals and to inhibit lipoxygenase (LOX) activity. Both of these activities increased after simulated gastrointestinal digestion. Aromatic additives, such as ginger, are able to change the antioxidant properties of coffee extract and antioxidant interactions may be identified using two methods. Antiradical phytochemicals from coffee and ginger acted synergistically - isoboles adopted a concave form, while after digestion in vitro an additive reaction was observed; in turn, chemical standards acted antagonistically. Water extractable LOX inhibitors acted antagonistically; however, after digestion in vitro synergism was observed. The same kind of interaction was determined for standard compounds. These results were confirmed by IF (interaction factor) analysis. © 2014 Published by Elsevier Ltd.

The article deals first with the problems of defining information. It is concluded that it is a misunderstanding to take a term and then to look for a definition. Rather a different way ought to be taken: to find the phenomenon first and then assign a name to it. The view that information is the same thing as a structure is considered. Then the processes by which information is created are analyzed. The definition that information is detected difference is closely scrutinized and it is found that information can also be detected sameness. It is argued that information is relative to the observer and for the very reason of the way it is created it is subjective. That extends only to information acquired. The existence of subjective information, however, does not prove information cannot exist objectively.

Yield variability of selected winter wheat cultivars under different sowing rate and selected application, was investigated during 2006-2008, in the Lower Silesia region (South-West Poland). Experiments with two varieties, two levels of sowing rate and seven herbicides, including untreated object were set up on the same field, using split-plot method. For evaluation of yield stability Kang's yieldstability statistic (YS) was applied. Examined herbicides did not influence grain yield of both cultivars, at standard wheat density (450 seeds/m 2). Under low density, Kobra Plus variety showed variable reaction to herbicides. Iodosulfuron methyl sodium + diflufenican + mezosulfuron methyl, mecoprop + MCPA + dicamba and iodosulfuron methyl sodium + amidosulfuron resulted in yield increment in comparison with untreated object, whilst dicamba + triasulfuron gave opposing effect. Yield stability at different herbicide objects during 3-years period was considerably variable and dependent on cultivar and sowing rate. Yield of both cultivars, obtained from plots treated with iodosulfuron methyl sodium + diflufenican + mezosulfuron methyl, iodosulfuron methyl sodium + amidosulfuron and mecoprop + MCPA + dicamba, under low density was comparable with standard sowing.

The aim of this study was to compare the suitability of several extractants for bioavailability of boron, copper, manganese, zinc and iron in soils to plants. For each element, 3 extractants were compared: so called specific, DTPA and EDTA. The specific method was different for different elements, hot water, nitric acid, magnesium sulphate (VI) and sodium sulphate (IV), or chloric acid solutions were used for boron, copper, manganese, and zinc, respectively. Total 156 samples were divided into 4 groups based on soil pH: very acidic, acidic, slightly acidic, and neutral. The extracted elements by different extractants from each soil group were correlated with the accumulated elements in plants. On this basis, suitability of extractants for estimate of bioavailability was tested. Results suggested that all the tested extractants were applicable for Mn, and none was satisfactory for B and Fe, EDTA and DTPA provided significantly better results for Cu and Zn than the specific one. © by PSP.
