Abstract

Purpose. To analyze the effect of biochar on the physical indicators of the substrate from the coal mining dump of DTEK Pavlogradska.To compare the effect of different concentrations of biochar to the substrate on the growth indicators of the studied plants - phytoindicators A.fatua and B.Leyss. Methodology. To consists in determining such physico-chemical indicators of the substrate as pH and electrical conductivity (EC), to analyze the different effects of biochar concentration on the substrate (1. substrate; 2. substrate + 10% biochar; 3. substrate + 15% biochar; 4. substrate +20% biochar) on the change in the physical parameters of the obtained substrate and on the growth parameters of the studied plants A.fatua and B.Leyss. Results. Based on the obtained results, such indicators of the substrate as pH = 8.78 and the value of electrical conductivity (EC), which was 301.9 µS/cm, were established. Different concentrations of the substrate with biochar did not affect the final physical parameters: pH = [8.78-8.9], and EC = [ 301.9 µS/cm -303.5 µS/cm]. The growth indicators of both studied plants showed better results on the studied substrate, where there was a ratio of substrate + 15% biochar. A.fatua had an average shoots length of 16.9 cm and a roots length of 9 cm, while B.Leyss had an average shoots length of 18.1 cm and a 9 cm roots system. This analysis makes it possible to consider this technology for phytoremediation of coal mining dumps. Originality. The influence of biochar on the physical parameters of the substrate taken from the tailings dump of coal mining DTEK of Pavlogradska and the growth indicators of the dependence of the studied plants A.fatua and B.Leyss on the amount of biochar in the substrate were determined. The results of the research make it possible to use this method of remediation as the initial stage of restoration of territories polluted by the mining industry. Practical implications. The obtained results make it possible to use this method as an effective method for the initial, biological stage of phytoremediation of a coal dump.
