Krzywy-Gawrońska A single-factor field experiment was carried out The Cultivar Evaluation Station in Szczecin-Dąbie in 2008-2010. <...> The soil on which this experiment was set up is formed from light loamy sand (lls). <...> Regarding its granulometric composition, the soil is classified to the category of light soils, of soil quality class IV b and good rye complex. <...> In the experiment, a combustion waste in the form of high-calcium brown coal ash was used, as well as a compost produced from municipal sewage sludge by the GWDA method. <...> A test plant was perennial Amur silver grass (Miscanthus sachariflorus). <...> The highest average increase in the nitrogen content in soil in 2008-2010 was observed in the objects fertilised with municipal sewage sludge compost at a dose corresponding to 250 kg N∙ha-1 with addition of high-calcium brown coal ash being introduced into soil in the first year of study and in next years, respectively by 23.3% and 27.7%, when compared to those with calcium carbonate or high-calcium brown coal ash being applied at the beginning of experiment. <...> The positive effect in soil richness indices was obtained after the application of municipal sewage sludge compost with annual introduction of high-calcium brown coal ash into soil. <...> In the soil of objects being fertilised with municipal sewage sludge compost without and with addition of high-calcium brown coal ash, the pHKCl value and the content of organic carbon and total N, P, K and S increased, as well as that of assimilable P, K and Mg forms. <...> Keywords: waste, sewage sludge, compost, soil, total content of macroelements and assimilable forms. <...> Many authors paid attention to the possibility of ecological and agricultural use of high-calcium brown <...>
