I have a large wooded tract that was logged about 15-20 years ago. I'm thinning now, to try and allow some of the regrowth to have room to mature, and of course the poor log trees were left and are now large and producing acorns, so I'm hesitant to remove too many of them. I'm also having some acre plus areas cleared with a dozer for foodplots. My question is, what's the best way once the dozer is finished to get the rest of the roots and rocks out of the way so that the soil can be limed, fertilized and loosened up for planting? I'm looking at renting a bobcat with a root grapple on it, and "tilling" the clear ground with it in hopes of ripping up the rest of the sapling stems and roots, etc that didn't get uprooted completely by the dozer. Any other ideas? Is there a heavy enough disk to cut through the 1 inch or so saplings and roots that are left? Would a tiller tear them up or just get clogged? Any ideas / tips would be much appreciated.
