Anyone know if the dead roots of mesquite soften over time and deteriorate, so they could could be worked with a tractor. Or no matter what are they still going to need to be plowed up with a dozer. Killing off mesquite with poison and a chainsaw but wondering if it is a waste of time, if it is going to take a bulldozer with a root plow to get the ground plantable anyways, it would just make sense to do it all at once. Correct? A dozer is not in the budget right now but why waste $100's on remedy if not needed.
