In the broad research project on the chemism of the meadow soil environment of the Lublin region a preliminary estimate of the current state of acidification of the meadow soils has been made. pH determination has been done in soil samples collected from 63 meadow locations of the region. The content of Ca, Fe and Mn in soil samples and vegetation of the meadows examined have also undergone determination. The results of pH determination showed that about 20 % of the examined soil samples are very acid, 40 % - acid or slightly acid, 30 % - neutral, and 10 % - alkaline. Very acid reaction concerned mainly light textured podzolic soils of the Podlasie region and the Lowland of Sandomierz as well as the majority of the post-bog soils and black earths. Slightly acid and neutral soils are those alluvial and soils developed on loess of the Lublin Upland. Generally, we can draw the conclusion that the soil reaction of meadow soils of the Lublin region is more dependent on the geographic location of the site rather than the local ecological conditions.
