The paper examines hydromorphic soils from the class of gley soils, soil type humogley. The examinedsoils are located in the protected part of the inundation of the middle course of the Danube. Accordingto the chemical properties of the examined soils, the pH value ranges from 7,64 to 8,15 on average, andwith depth there is an increase in alkalinity. The total salts of the examined soils had increased valuesin the humus horizon and ranged from 0,06 to 0,09%. The texture classes of the humus horizon of thesesoils are: clay loam to sandy clay loam, while the lower sub-horizons of the gley are textural classes ofsandy loam, loamy sand and sand. The influence of the Danube water level on the groundwater levelresults in high correlation coefficients, which range from 0,67 to 0,88. The groundwater in these soilshad the highest level from 28 cm to 70 cm depth, and the lowest level was from 110 to 175 cm deep.The amplitude of groundwater variation during the year in the examined humogley soils ranges from66 to 132 cm. Groundwater quality classes according to U.S. Salinity Laboratories are unfavorable andrange from C3S1 to C4S1, ie salt to very salty water with low sodium content, and according to theFAO classification the water quality is such that there is a moderate need for restriction. Highgroundwater level above the critical level, as well as watering the soil with water of this quality canhave an impact on salinization of the surface horizon of humogley soil of the examined area.
