MLRA 107 - Iowa and Missouri Deep Loess Hills Iowa, Kansas, Nebraska, and Missouri 53,810 km2 (20,770 mi2)

Soils:
Soils of the uplands are mainly Udolls. Orthents are also extensive. They are deep and medium textured and moderately fine textured and have a mesic temperature regime, an udic moisture regime, and mixed minerology. Well drained, gently sloping to rolling Hapludolls (Galva, Marshall, and Monona series) and gently sloping to rolling, somewhat poorly drained, Argiudolls (Higginsville series) are on loess-mantled uplands. Somewhat poorly drained, nearly level to gently sloping Hapludolls (Primghar series) and poorly drained, nearly level to gently sloping Haplaquolls (Marcus series) are on loess-mantled uplands. Somewhat excessively drained and well drained, strongly sloping to very steep Udorthents (Hamburg and Ida series) are in thick loess and on uplands. Well drained Hapludalfs (Knox series) are in narrow bands on slopes where moisture is favorable for growth of forest vegetation. Moderately well drained, moderately sloping to steep Argiudolls are on side slopes in clay loam glacial till. Well drained and moderately well drained Udifluvents (Haynie and McPaul series) and Hapludolls (Keg, Kennebec, and Salix series), somewhat poorly drained or poorly drained Fluvaquents (Onawa and Albaton series), and poorly drained or very poorly drained Haplaquolls (Colo, Luton, and Wabash series) formed in alluvium and are extensive on bottom lands.
