it The Stoneham soil is deep and .ell drained. It Eormed in calcareous <br />to=ss and alluvium derived dominantly iron mixed sources. Slope is 6 to 25 <br />percent. 't'ypically, the surface layer is yellowish brown loam 3 inches <br />thick. The upper 4 inches of the subsoil is yellowish brown clay loam. The <br />lacer 7 inches is very axle uram calcareous heavy loam. The upper 32 <br />inc:hes of the substratum is very pale brain calcareous loam. The laser part <br />to a depth of 60 inches is pink calcareous sandy clay loam. <br />l~rmeability of the Stoneham soil is moderate. Available water capacity <br />is high. Effective rooting depth is 60 inches or irnore. itunuff is rapid, <br />and the hazard of water erosion is high. the hazard of soil bloding is <br />hi~ah. <br />This unit is used mainly for native rangeland and wildlife habitat. It <br />is also used for gravel and road fill. <br />The potential alant community on the Schamber soil is mainly blue grama, <br />little bluestem, sideoats grama, a[d needleandthread. Tne average annual <br />prcc]uction of sir-dry vegetation ranges Fran 400 to 1,200 powids. <br />The potential plant community m the Stoneham soil is mainly blue <br />gra.na, western wheatgrass, and green needlegrass. 'it~e average annual <br />production of air~7ry vegetatirn ranges from 450 to 1,300 pounds. <br />If the range is overgrazed, the proportion of preferred forage plants <br />decrease and the proportirn of less preferred forage plants increases. <br />Therefore, livestock grazing should be managed so that the desired balance <br />of lreferred species is maintained in the plant community. <br />The suitability of this unit for rangeland seeding is poor. The main <br />lim.taticns for seeding are slope and droughtiness. Livestock grazing <br />shaild be managed to protect the unit iron excessive erosion. <br />/~0 <br />
