The subsoil, which extends to great depths, has about the same texture as the soil, but is of a lightyellowish color. The type forms flat valley lands lying only 5 or 10 feet above mean water level. It is naturally well drained and seldom subject to overflow. In narrow valleys where moisture conditions are favorable the type is cleared and cultivated. Broad areas often suffer from drought, and are left to the native growth of scrubby pine and oak. The soil is sedimentary, but the material is derived more or less locally from underlying sandstone. It is used for corn, of which 40 to 80 bushels per acre are obtained under good moisture conditions and heavy fertilization. Vegetables, strawberries, and cranberries also do well on limited areas, but the greater part of the type can only be safely used for agriculture with some system of irrigation. 1 2 3 4 5 6 7 Soil (2) 0 10 28 49 3 5 4 Subsoil (2) 0 10 32 50 3 3 3 Acres.

Sioux sandy loam.--The soil is a coarse to medium brown sandy loam or heavy sandy loam from 10 to 24 inches deep, containing considerable organic matter. The color becomes lighter with depth. The subsoil over wide areas consists of almost pure waterworn gravel, which is found at an average of 22 inches below the surface and extends to great depths. The subsoil, however, varies considerably, and the gravel is frequently bedded in a matrix of sandy loam, silty sand, or sand. This is an alluvial soil occupying river terraces or bottoms, with level to gently rolling topography. The drainage is too thorough where the pure gravel subsoil predominates for good crop yields, although the soil is early and might be profitably utilized in the p...
