<br />These gently to nuuleralely sloping soils are mt upland

<br />Average anneal precipitation ranges from l7 to 19 inches.
<br />.Julesburg sandy Janet, :i Lo (i percent slopes, makes up
<br />about rill percent of the map unit, :utd Et•kley gravelly

<br />'These suite are used almost entirely fur grazing. Small

<br />Rangeland cegut:aiun of the .luleshw•g soil consists of
<br />blue gram,, s:uul dropseed, sand recdgrass, little

<br />1Vindhrcxks and cnvirunmental plantings are difficult
<br />to establish un these soils. Soil blowing and steepness of
<br />slope are the principal concerns to establishing trees and
<br />shrubs. These hazards e•an be ocrrcumc by cultivating
<br />only in Lhe tree mw, by coirtuw• planting xnd by leaving a
