Abstract. The land of coal companies becomes unsuitable for further agricultural activities. Biological remediation is used to restore them. This study aimed to investigate the effect of soil improvers on plant establishment during biological remediation of disturbed landscapes in conditions of pronounced erosion processes. The present study analyzes the maturation processes of cultures in dynamics based on geospatial materials and maps of normalized relative vegetative index in biological remediation of the site of cultivated plant species and their positive response to the use of pre-sowing seed treatment with biological soil improvers and growth regulators. When the results of experiments on sites with varying degrees of preparation during the mining phase of remediation were compared, it was discovered that sites hydroseeded with a grass mixture had the highest efficiency in terms of survival rate and biomass growth. At the same time, the best result for hydroseeding was observed in plots with the application of a potentially fertile soil layer (loam). It was also found that the planting of trees and shrubs on the site with the application of loam and sector of technogenic eluvium slows down the initial vegetation process due to a longer period of plant adaptation, but does not have a great impact on the plant establishment. The data on biological remediation with soil improvers obtained from the experiment will be used for further analysis to determine the best phytoremediation technology for disturbed landscapes in conditions of severe erosion processes.
