Peridge soils dominantly occur on these isolated remnants on the Springfield Plateau. These include the Captina , Clarksville , Nixa , Noark , and Tonti series. These soils typically occur on the Springfield Plateau and should be at slightly lower elevations. Captina, Nixa, and Tonti soils contain a fragipan. Most areas have been cleared and are used for cultivated crops, orchards, pasture, or hay.
Principal crops are corn, small grain, apples, and vegetables.
Native vegetation was hardwood forest, mainly oak and hickory. The series is of moderate extent. Argillic horizon - 6 inches to a depth of 80 inches. Lithologic discontinuities - changes in parent material at 43 and 68 inches. Characterization of the typical pedon by the University of Arkansas Soil Characterization Laboratory.
