do a soil test. if the pH is so bad (<5.5) then it it will do little good to plant clovers. if you can get a 4wheeler to the site you can get lime, etc. to the site (semi-easily). like the others said, don't waste money, a soil test will tell you if you should move on to a next step.

also of note, I have planted and "plot" on logging roads in my woods (i limed & fertilized, etc.) and it came in great. However, there are areas where the seeding has been smothered by falling leaves. point is - plant in fairly open areas
