Sažetak
In recent decades, the establishment of short rotation energy plantations is becoming ever more common in marginal sites, including tailing dumps of open pits in mining basins. During the exploitation cycle, not only do short rotation energy plantations produce woody biomass for energy production, but they also accumulate large amounts of carbon from the soil and air. In this case, the energy plantations are primarily environmentally friendly, which is accompanied by their economic importance. Black locust (Robinia pseudoacacia L.) has a number of advantages that justify its use in the establishment of energy plantations. The main objective of this paper is to assess the current state of energy plantations of black locust established in autumn 2008 on a tailing dump of the »Kolubara« mining basin (Serbia), as well as to determine the yield of dry matter of black locust per hectare. The data on the number of trees, diameter and height increments, the mass of trees per diameter class and the amount of biomass were obtained by the method of partial survey. The survey found a high percentage of survival of black locust seedlings (95.67%), the average diameter in the plantation (6.83 cm), medium tree height (7.15 m) and the absolute yield of dry matter (2.96 t/ha/yr). The results of this research on experimental energy plantations will be useful in the planning of future energy plantations in low-productivity sites, as well as in the selection of techniques and technologies for utilization of energy plantations.
