Soil forming process running in hydromorphic conditions has a significant position in the landscape quality. These conditions can be permanent (wetland) or temporal, resp. interrupted during a year (wet and dry season). Result of the given conditions is creation of hydromorphic phenomenas described in this contribution. Basic soil parameters have been determined on selected sites (pH/KCI, H2O, CaCI2, C sub(ox), N sub (t), fractional composition of humus - HA, FA, Q sup (4)sub(6), as well as labile carbon content – C sub (L)). In addition, also iron in dithionite (Fe sub (d)) and oxalate (Fe sub(o)) extracts has been determined. On the basis of obtained results creation of (semi) hydromorphic phenomenas refers to: - heterogeneity of soil cover - reconstruction of genesis of soil and landscape - qualitative change of soils during their development - part of soil profile can be older than originally presupposed - soil with paleohydromorphism phenomenas occurrence can relatively well and long time keep their soil properties
