MLRA 73 - Rolling Plains and Breaks Kansas and Nebraska 59,260 km2 (22,880 mi2)

Soils:
Most of the soils are Ustolls. They are deep, well drained, and medium textured and moderately fine textured. These soils have a mesic temperature regime, an ustic moisture regime, and mixed and montmorillonitic mineralogy. The nearly level to moderately sloping Argiustolls (Harney and Holdrege series) are on loess-mantled uplands. Haplustolls (Uly series) and Ustorthents (Coly series) are on adjacent steeper slopes. Gently sloping and moderately sloping Haplustolls (Wakeen series) and Pellusterts (Bogue series) are moderately deep over shale on the more strongly dissected uplands. Haplustolls (Hord, McCook, and Roxbury series) and Ustifluvents (Hobbs and Munjor series) are on flood plains and terraces.
