FANG SERIES
The Fang series consists of very deep, well drained soils formed in alluvium derived from volcanic rocks, including welded tuffs, basalt and limestone with a component of volcanic ash. Fang soils are on alluvial flats, fan skirts, and inset fans. Slopes are 0 to 8 percent. The mean annual precipitation is about 175 mm and the mean annual temperature is about 12 degrees C.
