    The Conservation Requirements of Rare ind Threatened Vascular Plants of Natura 2000 Habitats of the Dolina Płoni i Jezioro Miedwie (Płonia Valley and Miedwie Lake) Special Area of Conservation

    The Dolina Płoni i Jezioro Miedwie (Płonia Valley and Miedwie Lake) PLH 320006 is one of the most valuable Natura 2000 sites in West Pomerania. It has been established to protect 17 types of natural habitats, 2 plant species, and 4 animal species. The aim of this study was the selection of the most valuable vascular plant species found in this site. From the 745 species recorded within the research area, 93 taxa of high environmental value have been chosen. Among them, there are legally protected species, as well as the taxa endangered with extinction perspective, vulnerable and rare to Poland and West Pomerania. More than a half of the valuable species constitute the indicators of natural habitats protected in the site. The most numerous are the species characteristic for natural and semi-natural grassland habitats. The major threats to the selected taxa include: eutrophication, improper water management, secondary succession caused by the abandonment of traditional agricultural methods, and simplification of the age- and species-structure of woods, which all result in the decrease of habitats biological diversity.

    The Response of Festulolium Braunii (K. Richter) A. Camus to the Amount of Seeds Sown and the Llevel of Nitrogen Fertilisation in Cultivation for Seeds
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Czyż, Henryk; Kitczak, Teodor; Faculty of Soil Science, Grassland Science and Environmental Chemistry, West Pomeranian University of Technology, Szczecin, Poland; Faculty of Soil Science, Grassland Science and Environmental Chemistry, West Pomeranian University of Technology, Szczecin, Poland
    The study was conducted in the years 2008–2011. Two factors were taken into account in the research: I – the amount of seeds sown: 9, 12 and 15 (kg · ha–1) and II – nitrogen dose: 0, 60, 90 and 120 kg · ha–1. The experiment was founded in the spring of 2008, with sowing with a nurse crop – spring barley, on brown soil of brown acidic subtype formed of light clayey sand of glacial origin – IVb soil valuation class. In the autumn of the year when the experiment was founded the following were applied – 80 kg P2O5 · ha–1, 80 kg K2O · ha–1 and 30 kg N · ha–1, and in spring – in the year of complete use, before vegetation, 40 kg K2O · ha–1 was applied and nitrogen fertilisation was replenished up to the amount assumed in the third factor of the research. The results of the study over Festulolium braunii of Sulino cultivar showed that on light soils it is possible to obtain an average seed yield of 13.5 dt · ha–1 – in the first year, 16.1 dt · ha–1 – in the second, and 15.3 dt · ha–1 – in the third year of yielding. The research revealed that when founding a seed orchard by companion planting with spring barley it was recommended to apply the amount of seeds sown of 15 kg · ha–1. On light soils the use of nitrogen fertiliser in doses of 60, 90 and 120 kg · ha–1 caused an increase in Festulolium braunii seed yield in the years of the study on average by 34.9, 46.3 and 53.3% respectively in comparison to the units fertilised only with phosphorus and potassium. The factors used in the research had also a favourable effect on the increased number of spikelets and seeds per inflorescence.
