In order to define the models of energy plantations of the short rotation on deposols of open-pit coal
mines, The Serbian Ministry of Science and Technological Development supported the researches
aimed at the determination of the post-exploitation areas suitable for the short rotation plantations in
the Kolubara basin. Besides the research of ecological conditions of the post-exploitation areas,
research of the development and productivity of biomass in the forest cultures established during the
biological recultivation, the comparative experiment was set with the number of fast-growing species,
in order to determine the technology of the soil preparation, feeding, density of sowing, measures of
protection, effects of phytoremediation, the selection of the mechanical devices, the analysis of the
economic parameters, etc. The aim of the research is the increase of the participation of energy from
biomass and partial replacement of the fossil fuels, in accordance with the Kyoto Protocol, Davos
Forum and other international agreements. This paper presents some results which are part of the
project.
Key words: Biomass, short rotation plantations, deposols, Kolubara lignite basin.
INTRODUCTION
The industrial, general-economic, as well as civilization
developments of the human community are inconceivable
without the energy sources. The non-renewable fossil
energy sources such as coal, oil and natural gas, which
account for 2/3 of the known world reserves of the
primary energy sources, are still the most important. The
coal accounts for 46% of the reserves.
Since Serbia is relatively poor in the reserves of quality
and high-calorie brown coals and since they are exploited
by the deep mines, they do not cause major disturbances
to the landscapes and nature ecosystems in these areas.
However, Serbia is rich in low-calorie lignite which is
mainly used for the production of the electricity in thermal
plants. The increasing need for electricity and the limited
hydro-energy potential as the most important, eco-
friendly, renewable potential, results to the further
increase of the lignite production in open-pit mines . It

implies the disruption of orography, destruction of the
ecosystems and further endangering of the environment
by the pollutants of the current and future thermal plant
(Drazic et al., 2007).
Short rotation forestry (SRF) in Europe has a long
tradition and originally aimed at providing a supply of fuel,
fodder and convenience wood, usually by means of
coppice systems. The main genera involved are:
Populus, Salix, Eucalyptus, Robinia, Betula, Alnus,
Castanea and Quercus. Eucalypt is confined to the
Mediterranean parts of Europe, whereas willow and birch
mainly are found in the northern parts. SRF systems are
employed in forestry and agriculture and have integrated
functions in agroforestry, shelterbelt- and environmental
applications such as vegetation filter systems. Modern
SRF has developed towards an industry which needs
large volumes and a continuous supply. Consequently
the focus is on species with a high initial growth rate and
breeding programmes are directed towards resistance or
tolerance against pathogens. With the actual range of
final products in mind (biomass for energy purposes,
paper pulp, particle board, veneer, construction wood) a
