-IS- ~HIBIT D (2 of 2) <br />EEY.t..lliZQY: Manure can be spread on the prepared surface at the <br />rate of 30 tons per acre; yr nitrogen (Ni and phosphorus (P205) <br />fertilizer ran be applied and incorporated at a rate of 40 lbs. <br />per ~3cre, each. Time of application should be immediately prior <br />tv seeding. If nitrogen and phosphorus are applied, a native hay <br />or s':raw mulch will have to be spread and crimped into the soil <br />at a rate of 4000 lbs. per acre after fertilizing. Mulch should <br />St1C)'. E" out of the soil. These measures will help control wind <br />and water erosion until grass becomes established. <br />S7L3S:i_~EE1j1II9: The seedbed should be well settled and firm but <br />friat~le for seed placement. Soils that have been over-compacted <br />by equipment should be tilled to breal.: up rooting restrictive <br />l.aye~s, then harro~.Ned, rolled er pacl.:ed to prepare the required <br />firm seedbed. Grass should be drilled using a grass drill from <br />Febr~.ary 15 to April 30 prior to a period of anticipated moisture <br />and after all other treatment is completed. Recommended planting <br />depth is 112" to 3/4". Species to be used should be: <br />Yar.iaiY ~eQ~ias eur.a_liiQ_sQa~La~;:Q <br />Vaughn sideoats grama 3.15 <br />Hachita or Native blue grama 0.40 <br />Arriba western wheatgrass 3.20 <br />Viva galleta (fleret~ 1.2D <br />Common sand drapseed 0.025 <br />(see attached seeding recommendation, CO-ECS-S, Part I) <br />Weed control should be maintained on the site during grass <br />establishment. Applicable treatment can include: pre-emergence <br />application of Ally at 1!1D ounce/acre or spraying with 2,4-D at <br />the rate of 1l2-3/4 lb. ai/acre after the grass is in the S-leaf <br />stage. IJo grazing should be allowed until there is a lush stand <br />and none before at least three growing seasons. Total area to be <br />seed=d should include all disturbed areas. <br />At the end of two years the success of the seeding should be <br />evaluated. If it is determined that an insufficient stand of <br />grass is present the area should be seeded again.
