Hi Rev,
that was quick. Eucalyptus is highly controversial, from Spain and Portugal to Brazil, better keep this can of worms tightly closed.
Melaleuca in Florida seems to be another problem hailing from Oz.
Jatropha is very useful, I have kept contact with Reinhard Henning of jatropha.de (English) for more than ten years now, and those wind breaks or live fences in Mali really are taking off. They now have 17 thousand kilometers of it. And each meter produces about one liter of oil per year. Go figure. That makes seventeen million liters, over four million gallons of oil, straight for the Listeroid field master.
But for agroforestry: the beneficial effect seems to be the synergy of nitrogen fixation, wind break, goat repellent, root growth factors and soil cover, aka living mulch.
And char in the soil works as a wick and storage medium for anything mobile, including water.
diazotrophicus
