Soil tillage and crop rotation create specific physical conditions for plant growth and influence the soil hydrological properties and soil water erosion process on sloped land. The aim of the current study was to trace the changes of the hydraulic properties of Epicalcic Chernozem under field experiment with winter wheat and maize rotation on sloped terrain and from the adjacent non-cultivated soil near to the village Trastenik, Ruse region, North Bulgaria. The field experiment has been performed for 3 years under wheat and maize growing under 3 variants of cultivation: up-and-down slope culture (T0), traditional contour tillage (T1), and crop specific erosion control contour tillage (T2). The T2 variant included minimum tillage, direct sowing and use of cover crop after wheat harvest as green manure before maize sowing. The soil sampling for determination of hydraulic properties was conducted in April and October each year. The water retentions at low suctions (pF 0.4–2.5) were determined on the undisturbed soil cores by suction type apparatus in the process of drainage, while water retention at high suctions pF 4.2 and 5.6 was performed on fine earth samples (< 2 mm) by pressure membrane apparatus and water vapor adsorption method, correspondingly. The saturated hydraulic conductivity was determined by falling head method on undisturbed soil cores. The results show a more persistent positive effect of the crop specific erosion control tillage (T2) on the increasing of available water capacity, air capacity and saturated conductivity even at the end of the vegetation season when the subsoil compaction was more severe pronounced in the other studied variants. Nevertheless, the results could not reach the conditions of the adjacent grassed land.
