    Opis:
    This paper presents the results of studies which aim was to determine the pollution of the water environment for both methods of preparation for the utilization of sewage sludge in agriculture. The study was conducted in 2008-2012 in lysimeters filled with light sandy soil (clayey sand). During the study variants with equal doses of nitrogen in an amount of 20 g . m-2 (15.7 g per one lysimeter) were supplied to the soil in sewage sludge and in the compost made from the same sludge. These variants were used three times for two species of perennial plants: Miscanthus gigantenus i Sida hermaphrodita Rusby. In a variant of sludge soil fertilizing, it was leached into water environment more than 12% of the applied nitrogen over 5 years of research. In case of compost nitrogen leaching was reduced to 8.1-10.0% of the quantity supplied to the soil.

    Opis:
    The pot experiment was set up with the split plot method in three repetitions in 2006. The objects of the first factor were the doses of manure and organic fertilizers to the soil in conversion to the brought in nitrogen (85 and 170 kg Nźha^-1). the objects of the second factor were the types of fertilizers: manure, sewage sludge and the composts prepared from sewage sludge. The soil used in an experiment was supplied from The Agricultural Experimental Station in Lipnik. The soil was taken from the arable layer, it has the granulometric composition of the light loamy sand. The content of available phosphorus, potassium and magnesium formed on medium level, the pH(KCl) of the soil amounted to 5.13. The soil was characterized by 0° contamination of trace elements, which means that it contained the natural content of cadmium, copper, nickel, lead and zinc. Spring rape var. l.icosmos was the test plant. The aim of the research was the assessment of the influence of manure, sewage sludge and compost prepared from sewage sludge on yield quantity of seeds and straw and the content of cadmium, nickel, lead and zinc in spring rape. The conducted research shows that fertilizers brought into the soil (manure, sewage sludge and compost prepared from sewage sludge) as well as two levels of fertilizing had a significant influence on the yield of the seeds and straw of spring rape. Manure, sewage sludge and compost prepared from sewage sludge played less significant influence on the decreasing or excessive increasing of heavy metals concentration in the seeds of spring rape. The double dose of fertilizers caused higher accumulation of heavy metals in the test plant. The straw of spring rape should be treated as a source of organic matter and the main nutrients for the soil. The highest concentration of copper, manganese, nickel and zinc in the straw of spring rape was noticed after the application of sewage sludge and of cadmium and lead after the application of compost prepared from sewage sludge.

    Opis:
    Agricultural usability of urban and industrial wastes was investigated in 2004 - 2006 in a pot experiment carried out in the vegetation hall. In the first year of the experiment maize was the test plant, oat grass in the second and oat in the third. The experimental design comprised 11 treatments differing with fertilizer and the kind of the supplied fertilizer components. The experiment used: mineral salts, farmyard manure, compost, municipal sewage sludge and industrial sewage sludge in two fertilizer doses. Metal concentrations in the test plants were diminishing in the following direction: oat grass > maize > oat. The lowest concentrations of the analyzed heavy metals were assessed in the plants fertilized with farmyard manure and compost (Zn, Cu). Among the tested plants the highest quantities of Zn, Cu, Ni, Pb and Cd were removed with the yield of the oat grass, then maize and oat. The highest uptake of Zn, Cu. Ni and Pb by plants was registered on a double dose of industrial sludge and Cd on a single dose of municipal sludge.

    Opis:
    The field and laboratory experiment was carried on the brown incomplete soil of the complex of rye good. The obtained results in the yield experiment show that the composts with the participation of municipal sewage sludge increased essentially the yield of the seeds of spring rape in comparison with the control variant. Doubling of the doses of mineral nitric - potassium fertilization against the background of the composts did not have a significant influence on increasing the yield of the seeds of spring rape in comparison with the single doses. The composts with the participation of municipal sewage sludge in the field and laboratory experiment caused a significant increase of the content of the available forms of phosphorus in the soil. As time went by the distribution of the composts in the soil, the content of the available forms of phosphorus increased.

    Opis:
    Pot experiment was conducted in the hall of vegetation at University of Agriculture in Szczecin over the years 2001 – 2003 on the soil of IVa complex of agriculture usefulness (very good rye) numbered among loamy sand as regards to the granulometric composition. The composts used in the experiment were after 8 months of decomposition. There was more nitrogen and phosphorus in the composts in comparison with potassium. In the pattern of the research the doses of composts, corresponding with 100, 200 and 300 kg Nźha-1, i.e. 0.63; 0.99 and 0.126 g N pot were used. The experiment was conducted in four repetitions. In 2001 spring rape Licomos variety was the test plant, in 2002 it was the spring triticale Wanad variety and in 2003 oats Polar variety. In the second and third year of the research of the soil there was 0.475 g N, 0.137 g P and 0.315 g K applied into every pot. It corresponded with the doses of 150 kg N.ha-1, 43.6 Pźha-1 and 100 kg Kźha-1. Mineral fertilizers were used in the form of urea, double superphosphate, 60% potassium salt. The obtained results of the research indicate that the content of the total forms of copper, manganese and zinc in the composts, with the participation of sewage sludge fulfilled the norms concerning the organic fertilizers. Over the years, since the time of an application into the soil the composts with the participation of municipal sewage sludge, the content of the total forms of copper, manganese and zinc has decreased. It was caused by the uptake of these micronutrients by plants.

    Opis:
    A single-factor field experiment was carried out at the Cultivar Evaluation Station in Szczecin-Dąbie in 2008-2010. In the experiment, the compost produced with municipal sewage sludge by the GWDA method was used and high-calcium brown coal ash at a dose corresponding. A test plant was Virginia fanpetals (Sida hermaphodrita Rusby). The obtained results show that Virginia fanpetals biomass contained on average the most nitrogen (3.72 gźkg-1 d.m.), calcium (6.03 gźkg-1 d.m.) and sulphur (1.24 gźkg-1 d.m.) in 2008, while the most potassium (4.39 gźkg-1 d.m.) in 2010. Significantly more phosphorus, magnesium and sulphur was contained by Virginia fanpetals biomass from the objects where municipal sewage sludge compost had been applied without and with addition of high-calcium brown coal ash when compared to calcium carbonate or high-calcium brown coal ash being introduced into soil at the beginning of study. Differences in average nitrogen, potassium and calcium contents in the test plant biomass from particular fertilisation objects were not significant. The macroelements uptake by Virginia fanpetals biomass depended on the yield size and the content of chemical elements under discussion in it.
