Abstract: | We used statistical data including specific calculations to show how the productivity of different biomass categories varies with land use, environmental conditions and land management at national and local level in Slovakia. Three different study sites were selected. Averaged annual productivity of the total biomass from one hectare ranged from 5.96 to 12.03 t on arable land, from 4.02 to 15.20 t on grasslands and from 11.72 to 13.56 t on forest land. Although the biomass productivity varied among the various biomass categories and the study sites, the average annual values of the total biomass per hectare from productive land was about the same at all three study sites (11.62, 11.68, 11.78 t/ha). Detailed quantification of different biomass categories offered a variety of possibilities to use them for further applications in economy and ecosystem services. At the national level, the unused biomass could have produced 29.8 PJ (petajoule) of heat energy. |
