Eugley soils are representatives of preterrace part of bottomland. They can be found in the area of relief depression, or in the lowest part of the floodplain. The main characteristic of these soils is excessive moistening with flood or groundwater. In the embankment protected part of the alluvial plain where there is no flood, the soil is moistened with groundwater. Groundwater dynamics of these areas is dependent on the level of the water level of the Danube River, which affects level of groundwater in a protected part of the alluvial plain. This paper presents the studies of eugley soil in the area of middle flow of the Danube River in Vojvodina (Nothern Serbia). External and internal morphology were determinated in soil profiles of eugley soil on the left bank of the Danube River, in part protected by an embankment. The particle size distribution of the soil was determined according to the international B-pipet method prepared in the sodium-pyrophosphate. Depth of groundwater of eugley soil in the tested area as well as soil moisture content at 10, 30 and 70 cm depth were measured monthly during 2011. Particle size distribution of the studied soils showed increased proportion of the total clay, the texture classes were sand, silty loam, and the most prevalent texture class was loam. Measured soil moisture content in 2011 at a depth of 10 cm was moving from 19.47 to 71.08 vol.%, At a depth of 40 cm soil moisture content ranged from 15.99 to 57.75 vol.%,while at a depth of 70 cm soil moisture was in the range of from 15.95 to 52.12 vol.% for all three studied soils. The level of ground water varied within the measured year. In the profile 1 ground water ranged from 50 to 190 cm below the soil surface, for the profile 2 these values ranged from 30 to 170 cm in depth, whereas in the profile 3 the depth of the groundwater was from 30 to 190 cm. It can be concluded that the soil moisture content at all three depths was the highest at the spring.
