<br />Harvey-Stoneham looms, 0 to 3 percent slopes
<br />(Hsg).--This complex rs on uplands, mostly in the
<br />aortbern half of the county in azeas up to 1,200
<br />acres in size. About 75 percent of each area is
<br />Harvey loam, wet, and about 25 percent is Stoneham
<br />loa.
<br />'the Harvey soil in this soil complex has the pro-
<br />file similar to that described as typical for the
<br />series. The Stoneham soil has the profile described
<br />as tvpit al for the Stoneham series.
<br />The principal inclusions are Olney sandy loam,
<br />0 to 3 percent slopes, and Manuel silt loam, 0 to 3
<br />percent slopes. Total inclusions account for about
<br />.0 percent of each mapped area.
<br />This is a good soil for range. The porous sur-
<br />face layer takes water well, and there is high
<br />rater-holding rapacity in the subsoil. There is a
<br />high hazard of sheet erosion in overgrazed azeas.
<br />Stock-water pits in this soil may need sealing.

<br />Haverson Series
<br />The Haverson series consists of deep, wel -
<br />drained, nearly level to ems on stream to rr es in
<br />the nonirrigated pazt of the county.
<br />In atypical profile the surface lay about 6
<br />inches thick, is pale-brown loam. It 's soft when
<br />dry and very friable when moist. Be w the surface
<br />layer and extending to a depth of inches is strat-
<br />ified pale-brown loam and silt to and li gh; brown-
<br />ish-gray silt loam. The substra is slightly hard
<br />to very hard when dry but is v ,~ friable when moist.
<br />It is easily penetrated by p nt roots, air, and
<br />rater.
<br />Haverson soils have a Berate to moderately slow
<br />intake rate, medium surf ce runoff, moderate to mod-
<br />erately slow permeab il' y, and high water-holding
<br />capacity, In places a soils are slightly saline.
<br />Then is a moderate rosion hazard in the form of
<br />gullying and stre ank cutting. These soils receive
<br />runoff from bord ing uplands, and there is a pos-
<br />sibility of fl ding vhen the streams overflow,
<br />llle entire creage is used as range. The native
<br />vegetation ns is is of blue grama, galleta, sand
<br />drops eed, .olla cactus, and four-wing sal tbush.

<br />Haverson loam, 0 to 3 percent slopes (HvB).--
<br />This soil has the profile described as typical f
<br />the series. lost areas of this soil occur as n row
<br />elongated areas along intermittent streams in e
<br />range part of the county.
<br />The principal inclusion is Limon silty c y, 0
<br />to 3 percent slopes, which accounts for ab t 20
<br />percent of each mapped area.
<br />This soil is relatively productive of ange for-
<br />age because of the supplemental water i receives
<br />from runoff. The surface is usually rough to be
<br />good for hay cutting. Erosion contr structures
<br />aze needed in places to control gul ing. (l:onirri-
