The research was carried out on two meadow objects with clearly different geochemical conditions of the soil environment (a small Ciemięga river valley and meadows surrounding three lakes of Uściwierz, Bikcze, and Nadrybie). Soil and plant samples (6 species – mainly meadow grasses) were taken in 2 vegetation periods – 1995 and 1996. The results showed that soils from the fertile valley of the Ciemięga river, as the ones derived from low peat silted-up by carbonates and loess silt, had a neutral reaction and a great content of basic components – especially calcium compounds. Boggy soils occurring in the second object, derived mainly from weakly decomposed low or transitional peat, had low ashness and a very acid reaction. In the chemical composition of almost all plant species there is a clearly more favourable situation in the samples from the Ciemięga river valley meadows. That allows to conclude that the trophism of meadow habitats to a great degree depends on the amount of Ca in the environment, because Ca – by deciding on the soil reaction - indirectly affects the mobility and, therefore, also availability of other nutrients for plants.
