Item No.7.13. Describe the method for seed bed preparation, and application method for grass/forb seeding Although seeding can occur on the site nearly any time between snowmelt and ground freezing, the optimum time for seeding is during the fall. Accordingly, the seed mixture will be seeded between the time the first killing frost occurs, usually sometime in September, and when the ground freezes, usually sometime in November. This scheduling of revegetation will allow the seeds to germinate and become established early in the spring when soil moisture is optimum. However, it may be necessary to seed at other times in some instances to either establish a ground cover to prevent soil erosion or to reseed an area in the event of failed seedling establishment. In these events, seeding may occur during the spring (April to May). The seed mixture will be placed by either a drill seeder or by broadcast seeding. The use of a drill seeder necessitates having slopes less than 3:1 (33 percent). Drill rows will be 20 to 25 centimeters apart. If the seed is broadcast, the amount of seed indicated will be doubled. Table 1 and Table 2 indicate seed application rates. Following seeding, straw or native pasture hay will be applied as mulch at a rate of approximately 2 tons per acre. If hydromulch is used, the rate will be % to 1 ton per acre. Straw or hay mulch will be mechanically crimped using a straight running disc on 10-inch centers. Normally, irrigation will not be required to establish a good stand of vegetation if seeding occurs with appropriate timing. Any prohibited noxious weeds that may appear in the reclaimed area will be controlled, as necessary, by chemical and/or mechanical means. Noxious weed control will be performed by a certified pesticide applicator 1 to 2 times annually (during the growing season). Seeding will occur as necessary and as the project progresses.
