Just acquired a 4-acre lot in Southern Virginia. It was recently cleared of a ton of small (roughly 6-foot-tall) pine saplings that look like they were mechanically planted. I am not entirely sure. There were as many as 10 saplings in every single square foot and they were clearly choking each other out. The saplings are gone now, and I am trying to figure out what steps to take to begin restoring the land for gardening, animals, carbon accumulation, food forest, all the permaculture/sustainability life goals. The main issue now is I have 4 acres of pointy ½ inch to 2-inch wide stumps. It is almost impossible to walk the property without tripping on a stump and goring yourself.
What is the best way to begin restoring farmland by removing thousands of ½ inch to 2 inch wide pine stumps?
