Note that the seedmix is <br />divided into three components, which will need to be bagged and <br />handled separately for seeding. Component G is the basic grass <br />mix, and should be drill seeded through the standard box of the <br />seed drill at a depth of 1/2". Component T is "trashy seeds" which <br />should be drill seeded through a drill box equipped with picker <br />wheels for trashy seed. The trashy seed should also be drilled at <br />a depth of 1/2". Component B is the portion of the mix to be <br />broadcast seeded. This can be accomplished by hydroseeding or hand <br />broadcasting after drill seeding has been completed, or by use of <br />various types of mechanized broadcasters. The seeding rate listed <br />for components G and T, is for drill seeding, while the rate listed <br />for component B species is for broadcast seeding. Note that the <br />rate for galleta assumes that entire florets will be seeded; the <br />rate should be reduced to 0.5 lbs/acre if this is not the case. <br />To enhance establishment of less competitive species of forbs and <br />shrubs which are included in the broadcast components, several <br />irregularly shaped areas of between .1 and .25 acres should be <br />excluded from drill seeding, so that only the broadcast seed <br />components are seeded in these areas. Rock piles and immediately <br />adjacent sites on the top of RP-1 would be appropriate locations <br />for the broadcast only seeding. Total acreage of broadcast only <br />seeding plots should be between 10 and 20 percent of the total <br />revegetated acreage. <br />Please contact me if you have any questions. <br />Sincer ,~/~~~ <br />r ~ <br />i <br />Dan T.
