Charles Paradise posted this topic recently, but it was scrubbed. I copied
the title and did a search, and read it. It was published as a series of
articles, then I guess as a short book. I think you will find it
interesting. Certainly his argument that low phosphate levels are a major
limiting factor in fertility holds true for land around here. Native trees
typically nodulate for P around here. Plants that don't normally do that,
(or that can't find a compatible microorganism) are pretty much out of luck
unless someone comes along with a bag of Phosphate. This is the address I
read it on: http://www.soilandhealth.org/01aglibrary/010134hopkins/010134toc.html
