~~ <br />UNITED STATES DEPARTh1ENT OF AGRICULTURE <br />SOIL CONSEP.VATIO`J SERVICE <br />San ;Liguel County gravel pits - Page 2 <br />February 15, 1979 <br />Again this is more of a quarry-tyre operation, and I feel little can be <br />done rr_th the side slopes. I ha~re not noticed any soil material that <br />wa.; set aside fcr surfacing. <br />Because of the sno*.a cover, I was unable tc malte any estimate of the <br />present vegetation on anal of the sites except Troy Rese~, however <br />I am including a copy of the potential native vegetation for each of the sites. <br />In n0' opinion the Norwood airport and Egnar pits would be similar to the <br />vegetation found under a Pinyon-Juniper Woodland aspect. The Basin pit <br />would reflect tre lower extremes of the Loamy Fcot_hill range site. <br />- Potential forage nroductior. could be somewhat loner than a typical <br />Loamy Foothills site. The Troy Rose pit would be similar vegetatively <br />to a Semi-Desert Loam range site in very low condition due to past <br />over-use. The Applebange pit could be classed as a Rivertottom <br />vegetative site. <br />In revegetatior., greater success can be expected if the disturbed <br />areas are shaped and graded, and covered with soil material to at least <br />a depth of 6 to 8 inches. We would reco.-emend late fall seeding on aL <br />sites to take advantage of available spring moisture and less reed <br />conmetition. I recommEnd the following broadcast seeding rates for <br />mixtures: Egnar, Basin and :dor-.rocd airp~.rt sites -- Vinall Russian <br />wildrye - 6 pounds per acre; Nordan crested wheatgrass - 6 pounds per <br />acre; Amar inte_:~.ediate wheatgrass - lli pounds per acre. Apolebaugh site -- <br />Sodar streamoank wheatgrass - 8 oounds per acre; :•?anchar smooth brome - <br />10 pounds per acra; Latar orchardgrass - 11 pounds per acre. Troy Rese site <br />Sand dropseed - >3 ncurds per acre; Palcma Indian ricegrass - 12 pounds per <br />acre. <br />I am also including a copy of a general soils map of the Dolores River <br />Basin for ycu_r use. I hope `phis iafox^nation will be cf help to you, <br />Sincerely, <br />G~:,~~ <br />Chris Gray <br />District Conservationist <br />Soil Conservation Service <br />tdorwood, Colorado <br /> <br />
