Yeah I had read this article thought it was interesting and read some scientific publications regarding agriculture, especially large scale. First and foremost, polyculture is not new, in fact it has been studied quite a bit. For large scale ag it results in overall lower yields. They have tried this stuff in a variety of ways and so far, it does not work best. Where it might work better is small scale subsistence farmers from which this is based. And that was not due to better yields, it was better for getting SOME crop rather than NO crop when weather was not good. A very different thing. They may well figure out a system that works for large agriculture, but so far this just results in less production. Also learned some other interesting things that conflicts with posts below as well.
