Fwd: Nitrogen in mesquite

I got this email from a couple in Oz who read the alt.permaculture
newsgroup. If anyone--hey you desert dwellers--can help them, you should
respond directly to them as I don't think they read this list. But please
post an answer here, too, since I'm curious. I assume that wood has less
nitrogen than leaves, but mesquite has such high-protein pods and
alkaloid-containing sap that I'd guess the whole thing is high in nitrogen.
