Miller, Pulaski, and Yahola soils occur on similar areas. Miller soils have a fine control section. Pulaski and Yahola soils have a coarse-loamy control section and lack a mollic epipedon. Port soils are well drained. Runoff is negligible on 0 to 1 percent slopes and very low on 1 to 3 percent slopes.
Permeability is moderate.
These soils are occasionally or frequently flooded for very brief periods during March to October. Mainly cultivated to alfalfa, small grains, grain sorghum, and cotton.
