Jones, District Conservationist DAT E July 16, 1981 <br />SITUATION: You regLested soil and vegetative data and recommendations far a proposed <br />gravel pit. 'This information is to be ;included in the Mined Land Application. <br />INFORMATION PROVIDED: Enclosed is a copy of the soil map for this parcel of <br />land. Following is a description and recommendations for the soil and vegetative <br />data. <br />1) Soil - Two soil types have been mapped on the proposed site, soil unit <br />1T 14C, a Guben loam and soil unit X62, a Borollic Calciorthids-Guben <br />complex. <br />The Guben loam is a very deep, well drained material formed in a thin <br />aeolian deposit over calcareous alluvial and glacial outwash. The surface <br />layer is a loam to heavy loam, about 11 inches thick. The subsoil is <br />gravelly light clay loam changing into a very cobbly sandy loam as the <br />depth increases to 60 inches or more. The soil has sufficient topsoil <br />to warrant stockpiling to be applied 12 inches deep during reclamation <br />of the site. This soil occurs on top of hills. <br />The other soil type is the Borollic Calciorthids-Guben complex, which is <br />an intermixture of two soil types. The Borollic Calciorthids soil is <br />very similar to the Guben, but differs mainly by having a larger volume <br />of coarse gravel and cobble on the surface and throughout the profile. <br />This soil is generally more shallow and is well drained. This soil <br />occurs on the side slopes of the pit area. - <br />2) Vegetation and Revegetation: - The present use of this site is rangeland. <br />Low shrubs and grasses dominate the site. The major shrubs present <br />are big sagebrush, low rabbitbrush, gray horsebrush, and prickly pear <br />cactus. The principal grass species present, in order of dominance, <br />include crested wheatgrass, western wheatgrass, needle-and-thread, <br />Junegrass, bottlebrush squirreltail, Kentucky Bluegrass, and cheatgrass. <br />Globemallow is the predominate forb. The present ground cover is 20 <br />to 25 percent, with an average annual production of approximately 1500 <br />pounds, air dry forage per acre. <br />
