<br />• depth bands- to allow seeding at the proper depth, <br />• seedbox agitator- to promote seed mixing, <br />• seedbox baffels- to aid in even seed distribution among rows, <br />• seed-metering device- to promote even seed distribution within rows, <br />• furrow openers- to permit proper seed placement from seed spouts, and <br />• drag chains- to aid in seed coverage <br />To complete the drilling operation, seedboxes will be loaded with the seed mixture and the drill <br />calibrated. Rice hulls or other inert materials, if necessary, can be used to promote seeding at the proper <br />rate. The drill will be adjusted to plant seed to the proper depth. The depth of seeding will be <br />approximately 0.25 to 0.50 inch under normal circumstances. Drill row spacing will be set at 6 inches. <br />The drill will be towed across the seedbed to complete the planting operation. Drill seeding will take place <br />immediately following the completion of final seedbed preparation techniques. <br />3.9 Broadcast Seeding <br />Broadcast seeding will be accomplished using hand-operated "cyclone-type" seeders or rotary <br />broadcast equipment attached to construction or revegetation machinery. All machinery will be equipped <br />with metering devices. Broadcasting by hand will be acceptable on small, isolated sites. When broadcast <br />seeding, passes will be made over each site to be seeded in a manner to ensure an even distribution of <br />seed. When using hopper type equipment, seed should be frequently mixed within the hopper to <br />discourage seed settling and an uneven planting distribution of species. <br />Broadcast seeding will take place immediately following the completion of final seedbed preparation <br />techniques. Broadcast seeding should not be conducted when wind velocities would prohibit even seed <br />distribution. The broadcast seeding rate for herbaceous species will be twice the rate of drill seeding. <br />Woody species will be established by broadcast seeding methods only. <br />3.10 Hydroseeding <br />This technique can be used on slopes too steep for drill seeding. Seed will be applied in a separate <br />operation and not combined with the mulching step. This technique will be applied immediately following <br />fertilizer incorporation. The pH of the slurry will be greater than or equal to 5.0. The slurry will be agitated <br />throughout the seeding process. Care will be taken to apply seed evenly over the area to be seeded. <br />8 <br />
