1 RRIGATION development is proceeding at a rapid rate in the United States as a result of public projects for harnessing waterways and of advances in technology for tapping ground-water sources effectively. In recent years 3 considerable area of Chernozem soils in a sub-humid climatic region has been brought under irrigation in Nebraska. Present Missouri Valley development plans call for a large increment in irrigated acreage of soils belonging to the Chernozem group in Nebraska and adjacent states, and a very rapid expansion of Pump irrigation throughout this area is currently evident. Reported changes in the chemical properties of soils due to irrigation apply, for the most part, to arid and semi-arid climatic regions where soils generally have limited profile development and are neutral to alkaline in reaction. Potentially irrigable Chernozem region soils in sub-humid eastern Nebraska, however, have well developed profiles with a moderately acid A horizon over a fine textured B horizon. Thus, an investigation of the influence of irrigation on the chemical properties of soils of the area in question seemed in order. A survey type problem was undertaken to evaluate salt accumulation trends, soil fertility changes and cation saturation trends in relation to acidity and alkalinity by comparing samples from local irrigated fields and immediately adjacent non-irrigated land.
