Dix Series The Dix series consists of gravelly, excessively drained soils that are neazly level to sloping and occur on terraces along intermittent streams. These soils developed in waterlaid, loose sand and gravel. In a typical profile the plow layer is noncalcareous, dark grayish-brown sandy loam about 7 inches thick. It is free of lime. The subsoil, about 11 inches thick, consists of dazk grayish-brown coazse sandy loam that is also free of lime. Fine gravel makes up about 10 to 15 percent of this layer. The underlying material is brown gravelly coazse sand that is free of lime, loose and somewhat stratified. These soils have rapid permeability and slow runoff. The water holding capacity and natural fertility are low. Because these soils aze periodically flooded, they are susceptible to severe erosion. The native vegetation consists of sedges, western wheatgrass, blue grams, side-oats grams, needle-and-thread, and sandreed grasses. Almost all of the acreage is cultivated, mainly to winter wheat or sorghums. In Phillips County the Dix soils were not mapped sepazately. They were mapped only with the Chappell soils in an undifferentiated unit and with the Wages and Eckley soils in a complex.
