Plasticity of pseudogley soils in Ub community

TLDR: In this article, 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.

Abstract: 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 %. Average values of the liquid limit in the arable horizon are about 38 %, and in the subarable horizon about 40 %. The optimal moisture for machine tillage of the investigated pseudogley and for other field operations varies between 19 and 22 %. Several other physical and textural characteristics are presented, including clay activity index and potential mechanical instability and soil susceptibility to treading.
