Abstract

The potential of bioenergy accumulation and production of Slovakian agricultural soils was derived. Energetically most productive are the soil types like Chernozems (88.6 GJ.ha-1) and Mollic Fluvisols (76.14 GJ.ha-1). The least energy amount generate Gleys, Organosols, Solonetzes and Lithosols (31.63 GJ.ha-1). Energy accumulated in farmland exploitability by plants cropped is variable depending from soil representative and its properties. The lowest exploitability was found at Cambisol (0.7–1.8 %), the highest at Regosols (3.1–7.0 %).
