• _S_ 1:XIiI~ BI (2 of 2) Earfiliz.r: hlanure can be spread on the prepared surface at the rate of 30 tons per acre; er nitrogen (N) and phosphorus (P2O5) fertilize,' can be applied and incorporated at a rate of 40 lbs. per sere, each. Tima of application should be in~~rnediately prior to saedino. if nitrogen and phosphorus are af+plied, a nativr_ hay or straw mulch ~e+ill have to be spread and crimped into the soil at a rate of 4000 lbs. per acre after fertilizing. 1~1u1~.h should sticl; 6" out of the soil. These measures will help control wind and water erosion until grass b?comes established. ~ir3S:3_$P_dlns: The seedbed should be ~..+ell settled and firm but friable for seed placement. Soils that have been over compacted by equipment should be tilled to bre.al; up rooting restrictive Jaye's, then harrowed, rolled or packed to prepare the required firm seedbed. Grass should be drilled using a grass drill from February 15 to Ap,•il 30 prior to a Feried of anticipated moisture and after all other treatment is completed. Recommend?d planting depth is 7/2" to 3/4". Species to be used should be: Ysri_t~ seasi_:, eur__lii____~~Ls_ra Vaughn sideoats 3rama 3.15 Hach•ita or Native bluo grams 0.90 Arriba western wheatgrass 3.20 Viva galleta (floret) 1.20 Common sand dropseed 0.025 (see attached seedrng recommendation, CO-ECS-S, Part I) Weed control should be maintained on the site during grass estat~lishment. Applicable treatment can include: pre-emergence application of Ally at 7/70 ounce/acre or spraying with 2,4-~ at the rate of 1i2-3/4 lb. ai/acre after the grass is in the 5-leaf stage. No g>'azing should be allowed until there is a lush stand and none before at least three growing seasons. Total area to be seeded should include all disturbed areas. At the end of two years the success of the seeding should be evaluated. If it is determined that an insufficient stand of grass is present the area should be seeded again.
