DEGRADED SOILS OF THE MOST BASIN AND THE POSSIBILITIES OF THEIR LOCATION, CLASSIFICATION AND RECLAMATION.

Brown Coal Research Institute j. v. c. (VÚHU) from July 2023, together with scientific teams from several European countries, participates as part of the EU research program in the solution of the REECOL project, which deals with the reclamation of areas affected by mining in European coal basins. This paper includes the results achieved in the preparation of the first sub-research report of the project, which deals with degraded soils. On the basis of archival data and own research, the concept of "soil degradation" was defined for the purposes of the REECOL project solution in the conditions of the Most basin, a set of laboratory analyses of soils suitable for determining the degree of degradation was determined, which will be modified in the course of the next solution in terms of efficiency and financial sustainability. The methodology of research is composed of terrain mapping, sampling and sample analysis realised by accredited test laboratories. The main part of the paper contains a brief description and localization of the areas of degraded soils of the Most Basin. The individual chapters briefly describe the areas affected by various types of degradation and the proposal for their reclamation, one locality is always described in more detail as a case study area. Part of the contribution is a map of areas affected by individual types of soil degradation. [ABSTRACT FROM AUTHOR]
