HCWCD REVEGETATION PLAN: PAGE 4 <br /> Seeding should be done using a grass drill. The drill should be equipped with <br /> a satisfactory seeding mechanism, agitator, double disk furrow openers, <br /> depth bands, and packer wheels or drag chains. The distance between drill <br /> rows should not exceed twelve inches. Seed may be broadcast in areas that <br /> are inaccessible for drilling. If the seed is broadcast, then the seeding rates <br /> in step #5 should be doubled. The broadcasted seed should be uniformly <br /> distributed over the ground surface and mixed into the soil either with a <br /> harrow or by hand raking. Planting (broadcast or drill method) can be done <br /> anytime between October 15th and May 15th. Irrigated seedings can also be <br /> planted between August 1 and August 31. <br /> Do not seed when the soil surface is frozen. The seeds should be planted <br /> between 0.5 and 1.0 inches deep. <br /> Step 6 - Mulch should be applied to the reseeded area to help moderate soil <br /> temperatures, to improve soil moisture absorption, and to improve soil <br /> holding capacity of moisture. Grass hay or cereal grain straw that is free of <br /> weed seeds is recommended for mulch. Apply 4,000 pounds of mulch per <br /> acre to the soil surface. At least half of the material should be ten inches or <br /> more in length. Do not use fine materials. The mulch should be anchored <br /> either with commercial netting products (on slopes steeper than 3:1) or <br /> mechanically. Mechanical anchoring can be accomplished using a heavy disk <br /> implement with dull blades to punch the mulch into the soil two to three <br /> inches deep. Crimping should not sever the mulch. <br /> Do not mulch when wind velocities exceed fifteen miles per hour. <br /> Step 7 - Supplemental water, if available, should be provided during the first <br /> two growing seasons to insure seeding success. Water should be applied at <br /> one-week intervals at a rate of 0.75 to 1.00 inches per application. The <br /> irrigations should begin no later than May 15th and continue until late July. <br /> Additional irrigations after July can be at the discretion of the party <br /> responsible for reclamation. During the secondgrowing season, enough <br /> supplemental water should be applied so that when combined with natural <br /> precipitation, two inches of moisture is received per month during June, July <br /> and August. After July of the second year, supplemental irrigations can be <br /> discontinued. <br /> 038 <br />
