I remove at least 25 large (18" to 30") pecan trees per year while thinning my trees and am looking for solutions to the stump problems. I have heard about using potassium nitrate and then burning, but I have not found this in my area (Tulsa) other than small, expensive containers. I also know this takes considerable time and effort for each tree.
On the mechanical side, I am looking at stump grinders that are not extremely expensive but are portable in the orchard/bottom land and can do the job without too much expense other than the initial purchase.
To compound the problem, I have another property that will need the same stump grinder starting next year but is 40 miles away. In addition, I could remove 25 per year for 20 years and still need to do more.
Any help on type/brands/suggestions is much appreciated.
