Due to the fact that we are running short of fossil energy and the world needs more environmentally friendly energy sources, plant biomass may be one of the solutions. Hoverer, biomass fuel faces difficulties related to cultivation of grass with particular chemical content (fertilisers along with the climatic and soil conditions are vital for productivity and yield quality, e.g., nitrogen fertilisers increase the yield and quality of grass plants notably), whereas combustion of this fuel may negatively impact the air quality (the whole process of thermal utilisation of solid biofuels is influenced by the kind of the solid biofuel used, its physical characteristics and its chemical composition. The chemical composition of solid biofuels has various effects on thermal utilisation thereof). This study aims at assessing the amounts of exhaust gasses emitted when burning meadow fescue and timothy biomass, changes thereof depending on the type and norm of the fertiliser applied, as well as researching the suitability of such biomass for biofuel production. It was found that timothy biomass has the lowest S and C content, while meadow fescue biomass tends to have the highest S content. The lowest S content was discovered in biomass fertilised with N dose F + N60, the smallest N volume when treating cops with F + N30, and the highest C with F + N120(60 + 60).
