Hopefully this is a good section to posts this, Will it work ? https://u.itemfix.com/2021/May/8/ItemFix-dot-com-6096ff335aaa5_vp.mp4
Seems reasonable, but it may depend on the type of tree you are using it on... Years ago I told a friend that had a bunch of evergreen stumps on his property, to take a chainsaw and make a bunch of vertical cuts down the center of each stump maybe a foot deep.. The go to the Industrial Chemical Supply Place and buy a Liter of 45% Nitric Acid, and pour it into the cuts on each stump... Then wait a month, and use a propane torch to light the center of each stump on fire, and let it burn... He came back later and was amazed, when the stumps burned completely out, including the root systems over a period of a few days.. He was very appreciative of the information... Nitrocellulose burns really well, and the capulary system of trees draws the Acid clear down the root system...
Yes copper is toxic to trees I have seen trees killed by driving copper roofing nails all the way around every 1.5 inches. As a plumber we use copper sulfate to kill tree roots in pipes
Gator down here it seems to take a bit longer on our hardwoods. That's what I've been told at least. Soft woods it reportedly works pretty well.
Many a logger has been injured or killed by Tree huggers driving copper spikes into trees just above the pitch pocket, and not only that but the copper will kill the tree pretty quickly! This was a serious concern here back in the 70's and 80's with all the anti logging protests and such! B.T' s post above using the Nitric Acid does the trick on stumps really well, almost too good, be careful with trees that have tap roots or very large root complexes, you can burn a lot more then just the stump your trying to be rid of!
I'm about to start a land clearing venture, Some of the stumps can be dug up, flipped and reburied, Others not so much.
I am in the process of clearing land also at this time, spend the days falling and cleaning up trees, but I would be afraid to use anything that would burn the roots and more given we're coming into the dry season here. Hell, even a whiff of a spark where I live would doom not only us but all our neighbors as well as we are surrounded by trees/forest. I might try it during winter but not keen on using chemicals in the ground... I suppose it would be okay as long as it all burns up but...I will have to think about this but would only try it during Winter or Fall... Think I will stick to my plan of renting an excavator...even though I got more than 30 stumps to dig out and burn just on the first section of ground.
Have you thought of renting a stump grinder? I have a neighbor up the road aways that does stump grinding. Charges me 1 dollar per inch of diameter of stump. Grinds them down as deep as you want. Might check into it in your area.
They work well, and if handled right, the chips are simply put back in the hole to decay overtime. The downside of that is subsidence and not much to fill in the hole or bare spot.
We dug up a couple of huge pine stumps today, Dug out a larger hole, Flipped the stumps back into said hole upside down and buried those baby's !
I was thinking that they used steel nails, which could be harmful to the logger, but the biggest threat was to saw-mill operators and their equipment.
