Doug,
sounds like VA Blue's got some regional experience/expertise. I can't comment on your soil or best seed. TBNers have proposed some good decision-making options for consideration. My land has about 1 acre's worth of compacted clay bare zones, where the thin top soil did not lay down. For using a Landpride model Lscape rake (Mine's a 1072):
* I removed every other tine on the rake for better penetration/scratching.
* I used repetitive passes at opposite angles and was able to scratch up 3" worth of loose clay/soil.
* For seed prep: Because I do have slope and some swailing, I scratched
downslope for final furrows. Then I seeded. Then I scratched slow, w/ a lot of 3pt control, across any sloping, to enhance water capture as it moves downslope (regardless of pitch of slope angle). My theory was that Scratching across also enhances my seed-soil contact.
* Subject to your seed and weather--- I watered every day for 4 days at dusk.
My grass/prarie mix seed is coming in. I do know though, that I'll have to plug and ammend in the fall. I thought it more important to get the grass established.
