I've been laying low for the last little bit but I swear I haven't been slacking – I cranked out a 2,500 word white paper describing a National Renewable Ammonia Architecture. This is headed for an appearance on [http://theoildrum.com The Oil Drum] and I think it'll be up tomorrow but now that it's done I'm itchy for people to read and comment.

  So, please wade right into my renewable fertilizer wonkery below the fold …
