The aim of this study was to evaluate the possibilities of using the SIG (Site Soil Index) for assessing the variability of the soil-site conditions on reclaimed and reforested spoil heaps of the lignite mining plant KWB ‘Bełchatów’. The studies were arranged on 4 substrate variants of the built up external and internal spoil heaps: on barren Quaternary sands (NWG), potentially abundant Quaternary loamy-sands (NWL), loam (NZL) and acidic sands Miocene strata after neutralization (NZG). The differences between these substrates are mainly in the acidity and texture. Non-significant differences between the values of SIG for soils on Quaternary substrates, but between soils developed on Quaternary and Miocene strata were found. The analysis showed the soil-plant relationships expressed in correlations of SIG and species richness (number of vascular plants). It was concluded that the use of the SIG index to diagnose the habitat conditions on the post-mining sites was possible, but rather auxiliary. For greater usefulness of SIG, the modifications of the value range for the site conditions scale were proposed in accordance with specific conditions on the post-mining facilities.
