 This paper is a short overview presenting the different areas of biomass ashes application in the agriculture and forestry. The advantages and disadvantages of biomass ashes as a source of nutrients for the plants are discussed.

The dynamic changes on energy suppliers market have been observed in Poland during last decade.  The EU policy by pressing great attention on the environment protection has great impact on the energy production sources balance. The emission CO2 quotas enforce the power companies to invest in renewable technologies, mainly wind farms and thermal combustion of plant biomass installations. This last technology, based mainly on fluidized bed combustors, is especially developed by electrical industry
