Alda and Fonner soils have gravelly sand in the lower part of the control section. Marksbutte soils have coarse sand and gravelly sand above 40 inches. Ovina soils are calcareous throughout. Sunset soils are calcareous throughout and in a drier climate. Wann soils contain more fine and coarser sand in the control section, are calcareous at or near the surface, and are somewhat poorly drained.
Novina soils are on bottom land and low stream terraces of major stream valleys.
They formed in recent alluvial sediments. Slope gradient ranges from 0 to 2 percent. The climate is subhumid. These are the competing Alda , Fonner , Ovina , and Wann soils and the Fonner, Merrick , Leshara , and Gibbon soils. Merrick soils are fine-loamy.
