In the paper the chemical composition of ashes from combustion of different kind of biomass and co-firing of coal and biomass was presented. Ashes from biomass, in general, have high content of macro elements as Ca and K. Increase of some macro elements in ash from co-firing of coal and biomass was relatively low, even share of biomass was 30%. Primary results of experiments indicate positive effect of ashes from biomass on yielding and some other parameters of chosen species of plants.
