    Cane Pruning IntensityoOf Vine as a Substantial Factor Influencing Physico-Chemical Attributes of Berries Cultivar ‘Regent’
    (Wydawnictwo Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Pachnowska, Kamila; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology Szczecin, Poland
    The research were focused on the assessment of quality attributes of berries cultivar ‘Regent’. The vines trained on Single Guyot training system were pruned at three intensities of 4, 6 or 8 buds per cane. Berries were harvested in three consecutive seasons (2013–2015) at the research station of West Pomeranian University of Technology Szczecin in Poland. ‘Regent’ grapes were analysed in terms of physical and chemical attributes, i.e. weights of clusters and 100 berries, total soluble solids, titratable acidity, pH, polyphenols, nutrients (Ca, Cu, Fe, K, Mg, Mn, N, P, Zn) and heavy metals (Cd, Pb). Our results showed that cane pruning intensity of vine cultivar ‘Regent’ had significant influence on the quality of berries, with the exceptions of cluster weight, titratable acidity and pH. Weight of 100 berries, total soluble solids and most of elements increased as the intensity of pruning increased. In turn, the lightest pruning treatment led to the greatest polyphenol, K, Cu and Fe contents in berries.

    The Effect of Multicomponent Mineral Fertilizers on the Content of Macronutrients in Soil After Sugar Beet Cultivation
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Sobolewska, Magdalena; Pużyński, Stanisław; Dojss, Dariusz; Hury, Grzegorz; Gibczyńska, Marzena; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland; Grupa Azoty Zakłady Chemiczne „Police” S.A., Poland; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland
    A wide range of multicomponent fertilizers, often with similar chemical composition, differs in the quality and digestibility of nutrients and price. The paper compared the effect of mineral multicomponent fertilizers from Polish and foreign producers on changes in the content of macronutrients in soil during sugar beet cultivation. The study also analyzed the effect of varying doses of fertilizers used. Fertilizers used were characterized by the following composition of NPK(S): two Belarusian 8–20–30, Russian 7–8, 19–20, 29–30 and Polish 6–20– 30(7) – Polifoska 6. The experimental plant was sugar beet of NATURA KWS cv., normal-sugar type. The soil on which the experiment was carried out was characterized by low abundance of available potassium and medium available phosphorus and exchangeable magnesium. The experiment was carried out in 2014–2017 in Lipnik. The study compared two factors: 1st factor – 4 multicomponent mineral fertilizers (two Belarusian, one Russian and Polifoska). 2nd factor – 3 doses of fertilization (minimum, optimum, maximum, which amounted to 2.5, 5.0 and 7.5 dt per hectare, respectively. Fertilization with multicomponent fertilizers did not have a significant impact on changes in the pH of experimental soil. In the experiment carried out, there was no difference in the performance of tested multicomponent fertilizers: Belarusian, Russian and Polish, regarding changes in the content of available phosphorus as well as available and exchangeable magnesium in the soil. The use of different doses of multicomponent fertilizers resulted in a significant increase in the content of available potassium and exchangeable magnesium in the soil, and the available phosphorus after using the highest dose of fertilizer.

    Inner-City Brownfields – Genesis, Specifics of Contamination, Possibility of Renewal
    (Wydawnictwo Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Kiepas-Kokot, Anna; Dusza-Zwolińska, Elżbieta; Department of Ecology, Environmental Protection and Management, West Pomeranian University of Technology, Szczecin, Poland; Department of Ecology, Environmental Protection and Management, West Pomeranian University of Technology, Szczecin, Poland
    A city’s post-industrial areas are a reservoir of attractive urban space which can both be reused for industrial purposes or managed in a different way. The economic transformation of the post-industrial era caused a high availability of brownfields in modern cities, mostly as a result of high costs of maintaining production in central locations. The available spatial resources were not suited for the needs of modern, concentrated, automated and fragmented production processes. The early industrial model of development enforced spatial development of cities that was tailored to the needs of industry. Revitalization of these areas is an opportunity for their efficient use. The main barrier in this process is, inter alia, soil contamination, which is poorly researched, highly varied, and expensive in liquidation. Soil and land contamination of brownfields is a permanent footprint of many years of high industrial pressure and it is substantially less considered than the environmental state of the surroundings of said brownfields. The pollution of soil within the areas of former industrial plants is often accompanied by the left-behind decaying infrastructure. Waste collected in industrial facilities can also be problematic. The characteristics of industrial sites in city centers strongly limit the possibilities of transformation. New legal regulations, which introduce historical soil contamination statuses and remediation plans, are an important stimulus for the intensification of processes of transformation of the industrial areas of city centers through the improvement of their ecological status and can, thus, be an effective path to sustainable urban development.

    Waste from the Harvesting of Button Mushroom (Agaricus bisporus) as a Source of Natural Melanin
    (Wydawnictwo Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Łopusiewicz, Łukasz; Center of Bioimmobilisation and Innovative Packaging Materials, West Pomeranian University of Technology, Szczecin, Poland
    Natural melanins are of great potential value and application in the fields of pharmacology, cosmetics and functional foods. In the present study, natural melanin was reclaimed from waste after the harvesting of button mushroom (Agaricus bisporus). The physiochemical properties of raw and purified melanin were determined, including their ultraviolet-visible (UV-Vis), infrared (IR) and Raman spectra. Colour values, polyphenolic content, antioxidant and antibacterial activity were also evaluated. The result showed that the characteristics of the obtained pigments were similar to synthetic L-DOPA melanin. Raw and purified melanins showed differences in chemical composition, antioxidant activity and light barrier properties. Isolated melanins showed antibacterial activity against Enterococcus faecalis and Pseudomonas aeruginosa but were inactive against Bacillus cereus, Escherichia coli and Staphylococcus aureus. This is the first research on the character of melanin reclaimed from waste after the harvesting of A. bisporus.
