Pozycja Open Access Analysis of the content of macro- and microelements in the leaves of sea buckthorn (Hippophaë rhamnoides L.)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Jaroszewska, Anna; Biel, Wioletta; Gibczyńska, Marzena; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, SzczecinSea buckthorn is used in the world primarily for its high nutritional value and unique healing properties. It is a plant with a small climate and soil requirements. The study was conducted to determine changes mineral compounds in leaves of sea buckthorn (Hippophae rhamnoides L. ssp. rhamnoides), depending on the substrate type and the passage of time and assessment of the potential for sea buckthorn growth on saline and degraded soil. The determined the amounts of nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, sodium, molybdenum, chromium, lead, and cadmium. Shrubs of sea buckthorn (Hippophae rhamnoides L. ssp. rhamnoides), of which leaves were collected in June 2015, were located in four sites in Szczecin. The soils, on which sea buckthorn bushes grow are alkaline. The different sites of the growing shrubs of sea buckthorn (Hippophae rhamnoides L.) and the applied fertilization resulted in the differentiation of P, K, Ca, and Mg in leaves of the plant, but no change in N content was observed. Leaf samples collected a year earlier contained more N and P and less Ca and Mg. Leaves of sea buckthorn growing on the banks of the Odra river contained over ten times more Na, twice as much Fe, three times as much Mn as leaves of shrubs growing elsewhere. There was no difference in the amount of Mn in the leaves over the years, while those collected a year earlier contained more Fe. No presence of Mo, Pb, Cr and Cd was recorded in the leaves of sea buckthorn (Hippophae rhamnoides L.). Uptake of large amounts of Na, Ca, and Mg by sea buckthorn indicates the possibility of its growing on saline and degraded soils and the passage of time.Pozycja Open Access Assessment of the progress of integrated pest management products implementation into agricultural production space(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Zatoń, Kinga; Błaszak, Magdalena; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, SzczecinThe study was aimed at assessing the progress of integrated pest management (IPM) implementation into agricultural practices. Assessment of farmers’ attitude to the new EU policy to reduce the use of insecticides as well as evaluating the real possibilities of biological methods use for plant protection was analyzed. Almost 60% of farmers whose farms were conducted in a conventional system declared the use of pesticides prophylactically. Farmers conducted intensive agriculture do not know the principles of IPM (prohibition of pesticides abuse). However, it is possible that these farmers know the restrictions introduced in 2014 without accepting them. It has been observed that in the group of farmers declaring the knowledge upon principles of IPM, the proportion of respondents aware of pesticides ecotoxicity increases. Therefore, a continuous education of farmers seems justified, but at simultaneous expanding the range of biological products and support mechanisms for farmers, who quit the intensive use of chemicals.Pozycja Open Access Metabolic potential of bacteria strains isolated from poultry industry waste(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Wrońska, Ilona; Cybulska, Krystyna; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, SzczecinMicrobial composition of poultry industry wastes was very diverse. They are inhabited by microorganisms that use organic substance to their growth. An appropriate composition of microorganisms is very important in the organic matter decomposition rate. Therefore, microorganisms that contribute to decomposition of several compounds are quite desired. The study dealt with the evaluation of metabolic activity of bacterial strains towards lipids, protein, and starch. The strains were isolated from the poultry waste environment. Metabolic potential of bacterial strains was determined based on the activity index and taking into account the hydrolysis zone diameter and colony diameter. Bacterial strains to a different degree decomposed the organic compounds. Their metabolic activity and direction towards substrates depended on the type of isolated bacterial strains.
