seeding is the preferred method end will be employed on the majority of reclaimed areas. <br />A rangeland type drill equipped with two seed boxes will be used for alt drill seeding. <br />This type of drill is capable of hnndling the rough and trashy surface conditions common <br />in retopsoiled areos and can be operated on relatively steep terrain. This drill is c~lso <br />adapted to seeding complex range mixtures because of the availability of two seed bores; <br />a legume box, end a large seed box with agitators. The seed mixes will be split into <br />large and small seed Components wi thi the small seed placed in the legume box and the large <br />seed plated in the large box. The drop tubes from the small seed box ere arranged to <br />broadcast the small seed on the ground with Light soil coverage accomplished by the drill <br />action and dreg chains. Seed in th e~ large box, requiring deeper seeding, will drop into a <br />furrow created by the contour disks end then will be covered by the dreg chains. The i <br />disks have one inch depth bands to control seeding depth. All drill seeding operations ~~ <br />will be done on the contour unless steep slopes restrict operations to up and down the <br />slope for safety reasons. <br />Broadcast seeding will be carried out in areas where drill seeding operations would be <br />restricted, including riprapped drainage channels and steep slopes that are to be <br />temporarily reclaimed. A roughened seedbed will be developed on temporarily reclaimed • <br />steep slopes which are to be broadcast seeded. These methods may include dozer tracking <br />or development of roughened surface conditions during construction activities. <br />Hydromulthing broadcast seeded areas or hydroseeding combined with hydromulching will be <br />used as optional methods on difficult sites. Hydroseeding end hydromulching ere detailed <br />below. Broadcast seeding will also be used in concentrated shrub seeding areas. A <br />Cyclone type seeder or EZFIou seeder Hill be used for broadcast seeding operations. <br />Broadcast seeding rates, where not specifically noted, will be approximately double the <br />drill seeding rates. <br />Hydroseeding, followed by hydromulching, may be used on permanently reclaimed steep slopes <br />where normal drill seeding operations ere not feasible. The surface to be hydroseeded <br />will be in es roughened a condition as possible. The hydroseeding rate will be 1.5 to 2 <br />times the drill seeding rate for the seed mix used. Hydroseeding will be completed as one <br />separate pass followed by a second pass to apply mulch and tackifier. Immediately after <br />completion of hydroseeding, [he area will be hydromulched with approximately 2,000 pounds <br />per acre of virgin wood fibre mulch and [00 pounds per acre of an organic tacking agent. <br />The tacking agent will be psyllium based or an approved alternative end water insoluble • <br />upon drying. Seedbeds comprised of plant growth medium, parent material, or spoil may _ <br />require fertilizer applications. Any fertilizer application will be based on ferCility <br />24 Revised 06/79/95 <br />
