_ f _,~ ~ ~ 7) Upon completion of seeding, the seeded area should be `'covered with weed-free grass hay, cereal grain straw or similar mulch material at the rate of approximately two (2) tons per acre. At least half of the straw material should be 10 inches or greater in length; fine materials should be avoided. Well-cured feedlot or barnyard manure may also be used as a combination mulch/organic matter and nutrient source for the seeded area. Recommended application rate is approximately 20 tons per acre, spread uniformly over the area. Repeated applications of manure for fertilization effect are not recommended, due to potential salt accumulation, Mulches will provide a more humid environment for seeding establishment, will help catch and conserve soil moisture, promote warmer soil temperatures in spring and fall, and protect newly germinated seedlings from wind and water erosion. "Hydro-mulchers" are commercially available which often expedite the mulching process on steeper slopes; contact the SCS office in regard to their use and availability. The mulch material should be stabilized and anchored by means of commercially available synthetic or jute netting (particularly on slopes steeper than 3:1), or mechanically through the use of a heavy disk implement will dull, parallel disk blades, in order to crimp the mulch into the soil 2 to 3 inches deep. Crimping should not sever the mulch. Mulching with straw should not be done when wind velocities are high. Mulching should be maintained on the seeded area for at least through the first full growing season. 8) The seeded area should be deferred from all machinery traffic for at_least until the end of the second full growing season, or until a reasonably good stand is established (possibly 3-4 years). Fertilizer application during the first few growing seasons, based preferably upon soil test findings, is recommended to provide optimum growth conditions. 9) In addition to the above recommendations, also refer to the following, enclosed documents for additional information and guidelines: - Colorado SCS Spec.
