I have a lease in North Fl. It is inside one of those timber companys. My soil PH was 4.2. You could make pickles with it. The first year I just planted iron clay peas. They grew ok but got wiped out quick. The next year I put down lime 4 months prior to planting. WOW what a difference that made. I have the same type soil (sandy) that you probably have. Where are you located? Iron clay peas have EXPLODED on my plot and the deer are trying but they just not keeping up.
