Healthy soil and sustainable growing

[Laurie Ann Powell <laurie@powellclan.com>]

I remember early on in this list's history that there was a discussion 
about sustainability. "The sun is always pouring energy into the earth, 
so sustainability is achievable even when a farm is 'exporting 
nutrients' by selling produce off-farm" was the basic premise.

That struck me as a very critical factor in the agricultural debate, and 
perhaps in the political landscape as well.

Does anyone have a good article on that, or a suggestion for a concise 
read I can share on the topic?

As always, Thanks for this discussion!
