Vegetation of a multivariant model experiment on coal combustion waste deposits. Part III

Abstract

An experimental study of the share of plants in the reclamation of combustion waste deposit from coal engineering was performed in the period of 2011-2016, fertilised with four types of compost and sewage sludge. Combustion waste deposits were contained in cylindrical containers with 80 cm in diameter (0.5 m2 area) and 100 cm high. Annually, during the vegetation period, the quantity and quality condition was assessed as well as the yield of fertilised plants. Great species diversity of significant biomass was observed. High reclamation effectiveness of combustion waste deposit was observed in the majority of fertilisation options. Biological reclamation of combustion waste sites with the use of soil formation deposits and vegetation is becoming more and more commonly applied and developed. To that end, many experimental studies have been carried out (model, lysimeter, field), one of which being the presented experiment.
