The Poocham series consists of very deep well drained soils formed in wind or water deposited silts and very fine sands. They are on terrace escarpments and along deeply dissected drainageways. Slope ranges from 25 to 80 percent.
Permeability is moderate in the solum and moderate or moderately slow in the substratum.
Mean annual temperature is about 48 degrees F and mean annual precipitation is about 42 inches. Poocham very fine sandy loam on a 64 percent west facing slope in a forested site. Solum thickness ranges from 10 inches to 15 inches. Coarse fragments range from 0 to 5 percent throughout the soil. Reaction ranges from very strongly acid to slightly acid throughout.
