Should we be able to use synthetic fertilizers in organic agriculture since the organic ones we can use in these systems are repackaged synthetics anyway? This was discussed at a really great lunch meeting today with scientists and growers (THANK YOU Mark C.!), and it's something that is really thought provoking. Watch the video (it's only 5 min), Dr. Brennan can explain way better than I can. Give it some thought.
H/T Eric Brennan.
Comments welcome.
Dr Brennan's reasoning toward the use of synthetic nitrogen in organic farming is persuasive but I see an error of omission. Dr Brennan failed to note that manure derived fertilizer will be produced whether or not it is used for agriculture. Cows poop. Chickens poop. Pigs poop. Goats poop. All god's creatures poop. And none of them are raised only to produce fertilizer. So the energy to produce argument seems weak. Also, while manures are used as pre-plant fertilizer and in some instances as a top dress or side dress for crops, fish fertilizers are also used. I have had very good results with a hydrolyzed (not emulsified) fish fertilizer with a very low N analysis. Perhaps just an academic point.
I'll forward your comment to Eric and see what he says.
