Study was performed in Haplic Luvisol in Hnevceves in the Czech Republic. Two soil profiles, which were in close distance from each other, were chosen: 1. under the conventional tillage, 2. under the permanent (30 years) grass cover. The micromorphological images were used to evaluated of all diagnostic horizons. The hydraulic properties of the diagnostic horizons were studied in the laboratory using multistep outflow experiments. A tension disc infiltrometer and minidisc tension infiltrometers were used to measure cumulative water infiltration under unsaturated conditions. The Guelph permeameter was used to measure cumulative water flux under surface ponding condition. Results showed, that while properties in thr Bt2 and C horizont are similar, properties in the Ap and Bt1 horizons were differrent.
