may require earlier termination of the fall seeding sea scn. Spring weather conditions <br />severely limit the opportunities for seeding of the perina Went mixes. The mon [h of May <br />will be the only consistent period available for spring seeding. All spring seeding <br />activities will be completed by June 1. Any transplanting, interseeding, or reseeding <br />of permanent reclamation would usually be accomplished concurrent ui th the regular <br />planting season. <br />Seeding will be accomplished by tlrill seeding, broadcast seeding, or hydroseeding. Drill <br />seeding is the preferred method and will be employed on the majority of reclaimed areas. <br />A rangeland type drill equipped with two seed boxes will be used for all drill seeding. <br />this type of drill is capable of handling the rough and trashy surface conditions common <br />in retopsoiled areas and can be operated on relatively steep terrain. This drill is also <br />adapted to seeding complex range mixtures because of the availability of two seed boxes; <br />a legume box, and a large seed box with agitators. The seed mixes will be split into <br />large and small seed components with the small seed pl ac e~i in the Legume box and the large <br />seed placed in the remaining box. The drop tubes from the small seed box are arranged to <br />broadcast the small seed on the ground with light soil coverage accomplished by the drill <br />action and drag chains. Seed in the large box, requiring deeper seeding, will drop into a • <br />furrow created by the contour disks and then will be covered by the drag chains. All <br />drill seeding operations will be done on the contour unless steep slopes restrict <br />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 <br />seedbed will be developed on temporarily reclaimed steep slopes which are to be broadcast <br />seeded. These methods may include dozer tracking or development of roughened surface <br />conditions during construction activities. Hydromulctii rig broadcast seeded areas or <br />hydroseeding combined with hydromulching wilt be used as optional methods on difficult <br />sites. Hydroseeding and hydromulching are detailed below. Broadcast seeding will also be <br />used in concentrated shrub seeding areas. A Cyclone typo :seeder or EZFIou seeder will be <br />used for broadcast seeding operations. groadc ast seeding rates, where not specifically <br />noted, will be approximately double the drill seeding rates. <br />Hydroseeding, followed by hydromulching, may be used on permanently reclaimed steep slopes <br />where normal drill seeding operations are no[ feasible. The surface to be hydroseeded <br />should be in as roughened a condition es possible. The hydroseeding rate will be 1.5 to 2 <br />13-26 Revised 01/15/93 <br />
