    The paper presents the geographical and historical spectrum of agrophytocoenoses flora of winter crops cultivation and a dozen year old fallows adjacent to them, in the area of the south-western part of the Szczecin Plain. A series of anthropogenic indices were determined. 242 phytosociologic releves taken within the area of differentiated soil conditions were used in the description. The affiliation of individual taxons to the geographical and historical status was determined and then anthropogenic indices were calculated. In regard to the scope of natural character of the examined flora biotopes, the contribution of nonsynanthropic spontaneophytes (Sp) is symbolic, and the indices are very small what results from the aricultural use of biotopes. The flora of both differently exploited habitats is under strong anthropopression and this is a favourable factor for synanthropization of phytocoenoses. The values of (Sw) and (Sp) are very large and they confirm the process of restructure of the communities. A clear change is observed in the floristic character of fallows in which the contribution of apophytes increases. The process of apophyzation is confirmed by larger values of indices (Aw) and (Ap) in phytocoenoses of fallows. In segetal communities of winter crops markedly dominant are archeophytes and the (Ar) index is significantly larger than that in the flora of fallows. The influence of a human being on the communities of winter crops cultivation is also confirmed by a larger index of flora general anthropophytisation (An). The contribution of kenophytes and diaphytes is symbolic and the indices of kenophytization (Kn) and fluctuation changes in the total flora (FLC) are very small. The high indices of total flora stability (TC) confirm the stability of floristic composition of the studied phytocoenoses.

    Wielkość i jakość plonu bulw potomnych frezji z grupy Easy Pot w zależności od rodzaju i dawki nawozu
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Żurawik, Piotr; Zawadzińska, Agnieszka; Pracownia Roślin Ozdobnych, Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Roślin Ozdobnych, Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie
    Experiments were conducted in the years 2006–2007, in spring-summer season, in the unheated foil tunnel. Corms and cormlets of freesia from Easy Pot Group (‘Gompey’, ‘Popey’ and ‘Suzy’) were the plant material. The influence of traditional fertilizer Azofoska and the slow-release fertilizers Osmocote Plus 5/6M, Osmocote Exact and Polyon 5/6 was evaluated in the experiments. Among all evaluated cultivars ‘Gompey’ was characterized by the greatest coefficient of corm number increase. Coefficient of corm weight increase depended on the size of planted corms. When freesia was cultivated from corms all fertilizers affected increase of both coefficients. Whereas, in experiments where cormlets were the plant material, Polyon affected decrease of the yield of freesia, independently on its dose. The greatest yield of corms was obtained when Osmocote Plus and Osmocote Exact were used, independently on cultivar, size of corms and dose of fertilizer.

    The study confirmed the impact of uncontrolled dumping waste sites on some chemical properties of soil, particularly in the surface layers. It manifests itself as: the change in pH within the landfill as compared to adjacent areas, increase of conductivity indicated on the higher salinity of soil, increase of organic matter content resulting from the deposit of organic waste, increased content of C and N and the extension of C:N ratio, which indicates on reduced ability of microorganisms to the processing of organic matter and increase in soil additives in the form of glass, metals, plastics, which can contribute to degradation of soils. The wastes stored at the surveyed illegal dumping sites within the area of municipality Kobylanka not significantly affected the heavy metal contamination of soils. The most of soil samples shall be eligible for the soils with the natural category of Cr, Cu, Hg, Ni, Pb and Zn content. Only a few samples of soil were classified to category with increased content of Zn, Cu, Pb and the average of Ni and Cr.
