Nitrogen is easy. It's the lack
of replaceable phosphorous that we really need to be worried about.

I would be interested in hearing people's reaction to this
article. His premise is that we cannot replace our "Green
Revolution" food growing methods with purely organic methods because
those don't produce enough nitrogen. He omits the concept of
polycropping as a potential solution. I'm especially interested in any
case studies or documented examples that would refute his premise. |
