During 1993 - 95 81 plant communities of high legumes percentage were analysed. These communi- tes were grown mainly on the light and very light soils. The mean soil pHxci values ranged within 5.3 - 6.3 Generally, high Mg content, moderate Mn, Fe, Cu, Zn contents and low P, K contents were found in the soil. The legume plants appeared to be rich in N, Ca, Mg and deficient in Na and Zn. Significant linear relationship was observed between N, P, K, Ca, Mn, Zn contents in plants and soil pH values.
Twelve physiographic regions, determined in Kraków province, were analysed using 1398 Braun- Blanquet phytosociological surveys of grain and root crops. The evaluation was made according to the Ellenberg method in which, weeds were considered to be indices of thermal (T), humidity (W), soil reaction (R), nitrogen content (N), and soil biological activity (G) conditions. The method proved to be useful to demonstrate differences between studied mesoregions.
