The research was carried out on two meadow objects with clearly different geo- chemical 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.
