I woukd take the time to do a soil sample. Not sure how many acres you are trying to lime, but could get quite expensive with any "fast acting lime" (don't have any experience because wouldn't be feasible at our place). We did one a few years back at a club I was in that called for 3 tons/acre in Coosa county. Basically we were wasting money on fertilizer the few years before we did it. Call the co op and just get a lime truck out if this is possible on your property. You have time to get a soil sample if you went this route because you want derive much benefit in your planting this year anyway. Just my opinion
