NOSHADE SERIES

The Noshade series consists of very deep, well drained soils that formed in alluvium derived from granitoid with limestone rocks. The Noshade soils are on fan remnants. Slopes range from 1 to 4 percent. The mean annual precipitation is about 150 millimeters (6 inches) and the mean annual air temperature is about 15 degrees C (59 degrees F).

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, thermic Typic Haplocalcids
