concurrent with the regular planting season. <br />Seeding will be accomplished by drill seeding, broadcast seeding, or hydroseeding Drill seeding <br />is the preferred method and will be employed on the majority of reclaimed areas. A rangeland <br />type drill equipped with two seed boxes will be used for all drill seeding. This type of drill is <br />capable of handling the rough and trashy surface conditions common in retopsoiled areas and <br />can be operated on relatively steep terrain. This type of drill is also adapted to seeding <br />complex range mixtures because of the availability of two seed boxes; the legume box, and the <br />large seed box. The seed mixes will be split into large and small seed components with the <br />small seed placed in the legume box and the large seed placed in the remaining box. The drop <br />tubes from the small seed box are arranged to broadcast the small seed on the ground with <br />light soil coverage accomplished by the drill action and drag chains. Seed in the large box, <br />requiring deeper seeding, will drop into a furrow created by the contour disks and then will be <br />covered by the drag chains. All drill seeding operations will be done on the contour unless <br />steep slopes restrict operations to up and down the slope for safety reasons. <br />Broadcast seeding will be carried out in areas where drill seeding operations would be <br />restricted, including steep slopes that are to be temporarily reclaimed. A roughened seedbed <br />will be developed on temporarily reclaimed steep slopes which are to be broadcast seeded. <br />These methods may include dozer tracking or development of roughened surface conditions <br />during construction activities. Hydromulching broadcast seeded areas or hydroseeding <br />combined with hydromulching will be used as optional methods or on difficult sites. <br />Hydroseeding and hydromulching are detailed below. Broadcast seeding will also be used in <br />concentrated shrub seeding areas. A Cyclone type seeder will be used for broadcast seeding <br />operations. Broadcast seeding rates, where not specifically noted, will be double the drill <br />seeding rates. <br />Hydroseeding, followed by hydromulching, will be used on permanently reclaimed steep slopes <br />where normal drill seeding operations are not feasible. The surface to be hydroseeded should <br />be in as roughened a condition as possible. The hydroseeding rate will be 1.5 to 2 times the <br />drill seeding rate for the permanent 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, the area will be hydromulched with 3,000 pounds per acre of <br />virgin wood fibre mulch and 70 pounds per acre of an organic tacking agent. The tacking <br />agent should be guara based and water insoluble upon drying. If guara is not available, it may <br />be necessary to substitute psyllium based material at 100 pounds per acre. Fertilizer, at an <br />approximate rate of 200 pounds per acre of 18-46-0, will <br />29 Revised 3/99 <br />
