The best organic fertilizer: urine
The key to this technology is fertilization. While chemical fertilizers can be used, Dr.Daniels suggests a much better alternative: an organic, domestically produced, high-power fertilizer. Regarding fertilizer, considering the expense of commercially prepared fertilizers, the amount needed for a full-size deck garden and the fact that many of them don't work well, I have found that urine is the best fertilizer for this system. The decaying leaf medium breaks it down almost instantly so that there is never any odor, and germ survival in material such as this has been shown to be practically nil. We call this liquid organic fertilizer (LOF).

I hope our organic veggies arn't coming from here.
