disc plowing the topsoil and subgrade together, a practice typically used by commercial <br /> landscapers. <br /> • GIR will replace topsoil in as even a manner as equipment allows. Soil amendments will be as <br /> recommended by the local NRCS. Presently, they recommend that if soil tests are not preformed, <br /> forty(40) pounds per acre of each of the major nutrients (nitrogen and phosphoric acid (P2Os)) be <br /> applied.They also recommend a combination of mulch or other organic matter and a nutrient <br /> source such as well-cured feedlot or barnyard manure be applied. The recommended application <br /> rate should be at least twenty (20) tons per acre, evenly spread. The manure must contain at least <br /> 60% (by weight) large chunks, five inches or more in diameter. (Granular or powdery manure will <br /> not meet specifications.) <br /> If phosphoric acid is applied, it will be applied on the overburden prior to plant growth medium <br /> replacement.This nutrient is not mobile. Placing it in the root zone prior to plant growth medium <br /> replacement will ensure optimal utilization by plant roots. <br /> The seedbed will be well settled and firm, but friable enough so the seed can be drilled at the <br /> recommended depth. Soils having been compacted by traffic or other equipment will be tilled <br /> (deep-chiseled or ripped if necessary) breaking up restrictive or compacted layers, and then <br /> harrowed and rolled or packed to produce the required firm seedbed. If the seed is to be broadcast <br /> seeded, then the seedbed will be settled and fairly firm, but left rough enough to catch the seed <br /> and allow some coverage by soil when tracked in by equipment or harrowed and packed into the <br /> soil surface. Seedbed preparation will be avoided when the soil is wet to prevent seedbed <br /> compaction. Planting depth will be less than one inch. Drill row spacing will be approximately 8 <br /> inches. <br /> (j) State the grass,forb and tree species to be planted and the application <br /> quantities. Specify the quantity of each grass and forb species as <br /> pounds of pure live seed per acre: <br /> The seed mix recommended by the DRMS Inactive Mine Lands Program for high elevations <br /> shall be used to revegetate the site. Please see Section 3.1.10, below. <br /> (k) Specify the application methods for grass and forb seeding, drill seeding <br /> or broadcast: <br /> Dependent on the ability to gain access in a safe manner, the revegetated sites will either be <br /> drill seeded or broadcast seeded. If an area is broadcast seeded, the seeding rate will be <br /> doubled. <br />
