Summary:
The paper shows the results of the third year of research into biopotential and energy properties of indigobush. The research is planned to last for 6 years. According to the annual plan, the experiments were done in sample plots 1 and 3 in the third year of research. A research block polygon was established in a thirteen-year-old natural stand of indigobush in the compartment 126a of the Management Unit Posavske Šume, Sunja Forest Office, Sisak Forest Administration. The research is based on a project protocol and annual work plans and is carried out in four experimental fields, each containing six 5 x 5 m experimental plots. The basic task of the scientific-research project is to determine trends in bioproductive or bioenergy capacity in naturally planted indigobush at repeated felling operations. The time rhythm of the research was determined by the number of the plot, in combination with the project protocol and annual work plan.
Indigobush, particularly in the lowland systems of the Posavina region, covers large areas of forest soil. In some of these areas indigobush is so widespread that its shade prevents natural regeneration of stands of valuable autochthonous tree species. As a species of light, indigobush invades forest areas after tree cutting and overshadows the desired autochthonous young growth with its dense canopy. For this reason, it is perceived as an aggressive plant and a very dangerous weed, since not only does it considerably hinder the regeneration of Croatia’s most valuable lowland forests but also makes it more costly.
The possibility of using indigobush biomass for energy is limited by a number of factors. The most important ones include the quantity of biomass per surface unit and the profitability of its harvesting, chipping, transport
