The pH, electrical conductivity, sodium-adsorption ratio, saturation percent, hydraulic conductivity, NO3 content, and NaHCO3-extractable phosphorus were determined on an irrigated Solonetzic soil complex. The soils were sampled to the 142-cm depth at 20 locations on a small, levelled field. Yields of barley were obtained in the field and in the greenhouse on soil cores. Stepwise multiple regression analyses indicated that hydraulic conductivity and available phosphorus in the 0- to 15-cm depth were the most important factors explaining yield variation in the field. In the greenhouse, available phosphorus was more important and hydraulic conductivity was of secondary and minor importance.
