Opis:
A field experiment was conducted univariate in 2008-2010 in the Variety Assessment Station in Szczecin - Dąbie. The soil on which the experience was based is made of light loamy sand (pgl). In terms of granulometric composition it includes it into the category of light soils, agricultural suitability complex IV b, good (5). The experiment included, inter alia, waste compost produced with municipal sewage sludge produced by *GWDA and ash from brown coal (waste grate). No normal ranges for heavy metals being specified in the ministerial regulations were used for environmental purposes, which are maximum 20, 500, 750, 300, 1000 and 16 mg per 1 kg dry matter for cadmium, chromium, lead, nickel, copper and mercury, respectively16 were exceeded in the sewage sludge being used to produce the compost. The field experiment design consisted of 6 fertilisation objects. A test plant was Virginia fanpetals (Sida hermaphodrita Rusby). The content of available phosphorus, potassium and magnesium in the soil, being fertilised with municipal SSC with and without an addition of high-calcium BCA, changed after three years. There was an increase in the content of available phosphorus, potassium and magnesium forms, on average by 8.5%, 16.0% and 9.0%, respectively. When analysing the chemical properties of soil before and after this study, it may be stated that respective systems of municipal sewage sludge compost and high-calcium brown coal ash application differently affected most soil richness indices. The best fertilisation effects were obtained in the system with municipal sewage sludge compost being applied at a dose corresponding to 250 kg N ∙ ha-1 as well as with high-calcium brown coal ash at a dose corresponding to 1.5 Mg CaO ∙ ha-1 being introduced into soil in the first year of study and at a dose corresponding to 0.75 Mg CaO ∙ ha-1 in successive years. Fertilisation with municipal sewage sludge compost without and with addition of high-calcium brown coal ash favourably affected the preservation of soil environment stability and improvement of soil chemical composition.

Opis:
The three-factorial vegetative-pot experiment was carried out in 2007-2008. The first factor consisted of the series with and without compost of municipal sewage sludge and the second factor involved doses of multi-component mineral fertilizers. Perennial ryegrass (Lolium perenne) of Stadion cv. was the test plant. The purpose of the work was to determine the effect of mineral multi-component fertilizers with combined organic fertilization on the content total and forms assimilable of macroelements in soil. Single doses of mineral fertilizers and urea increased the content of nitrogen, phosphorus and potassium in the soil compared to the control. Doubling the doses of fertilizers and urea raised the content of nitrogen, phosphorus and potassium in the soil as compared to single doses. Types of multicomponent mineral fertilizers with the addition of urea did not have a major impact on the diversity of studied elements content in the soil. After two years of experiment, the soil to which compost was introduced in spring contained more nitrogen and phosphorus compared to the control object by 21% and 8.96% respectively. The potassium content in the soil was the same as in the control object. Doubling the doses of mineral fertilizers and urea with the participation of compost resulted in an increase in the content of available forms of phosphorus, potassium, magnesium and sulfate in the soil by 2.52%, 9.12%, 2.25% and 0.80%, respectively, in comparison with single doses. The content of available forms of phosphorus and potassium in the soil after the end of the experiment was greater than of the available forms of magnesium and sulfur.
