In my climate, if I girdled a willow it would just send out a million suckers. I have never seen a willow die without a great deal of help!
Not neccesarily a problem, but since the stump won't die, I think I'd coppice willow for chips etc.
Imagine all the hurdles I could weave...
I'm thinking that alder might be a good tree to plant in an orchard. I know they send up sprouts when you cut them down, but perhaps removing the occasional sprout would be easier than always bringing in municipal mulch, no? I also wonder if deer would help control sprouts. I have a lot of them here. In the wild, apple trees often grow with alders, and the alders fix nitrogen in their roots. It seems to me that a lack of roots is the problem with most soil erosion, infertility, and water runoff. If I can get roots deep into the soil, especially roots with nitrogen nodules attached to them, then I'd have a healthier orchard.
I was fascinated by Masanobu Fukouka's success with transforming a dying modern orchard into a healthy natural orchard without fertilizer, pesticides, or compost. One method he described involved planting black wattle, a nitrogen-fixing (though highly invasive) tree in the orchard, and then cutting it down after a few years and burying its branches right there in the orchard.
I recently purchased farmland, with a foot of black topsoil remaining on it, but there isn't anything living in it. Decades of plowing, chemical herbicides, fertilizers, pesticides -- you know the story. I'm thinking European Black Alder might work for my northern climate (zone 4a) and would add much of what this soil is sorely lacking: hummus. Food for fungi and microorganisms. Soil aeration. Water retention. etc. I'm thinking this would be better than importing municipal mulch that could be contaminated as Paul mentioned.
