<br />Bailer Series
<br />' The Bailer series consists of shallow, well drained
<br />soils on ridges and hill slopes, mainly on the east-lacing
<br />dip slope of the Dakota Hogback. The soils Termed in
<br />' noncalcareous, stony, loamy material derived from
<br />sandstone of the Dakota Formation. The slope is 15 to
<br />50 percent. The average annual precipitation is 15 to 17
<br />inches, and the average annual temperature is 47' F.
<br />' The Irosl-free season ranges from 126 to 142 days.
