The aim of the paper is to compare the ecological values of the index figures of soil temperature-T, moisture-W, soil acidity-R, nitrogen content-N and biological activity-G, calculated without the covering ratio of species, and T1, W1, R1, N1, G1 values calculated with the covering ratio of species and test when the frequency of species in agrocenosis has indicator value. The use of Ellenberg's ecological indicators showed a variation of habitats in soil agricultural suitability and types of soil, especially when the covering ratio of species was included in calculations
