example 6 Argidurid
landscape
Elmore Co., ID
Soils of
these landscapes commonly contain a silica- and
CaCO3-cemented duripan at a relatively
shallow depth. The duripan impedes the downward
growth of roots and the movement of water in the
profile. These landscapes receive ~10" of
mean annual precipitation and are used mainly for
rangeland. However, in areas where the soil is
deeper, some irrigated crop production does
occur. When irrigated, these soils are used for
pasture, hay, corn, small grains, sugar beets,
and potatoes. Vegetation in the potential natural
plant community is mainly Wyoming big sagebrush,
bluebunch wheatgrass, Sandberg bluegrass, and
Thurber needlegrass.
