The paper includes the results of determination of Atterberg plasticity limits of arable (0-25 cm) and subarable (25-50 cm) horizons in 53 pseudogley profiles from the community of Ub. On the basis of performed laboratory investigations, it has been found that the pseudogley belongs to the group of moderately plastic soils, with plasticity index higher than 17. In the arable horizon, average moisture at the plastic limit is about 20%, and in the subarable horizon - about 19%.
