This is one of those times when I say 'I do not know'.
I've generally had the same experience, but these guys are surprisingly (almost intimidatingly) committed young guys who are working on the marriage of permaculture and aquaponics with Earthship systems - cool guys who were down to talk cation exchange and water food web vs soil food web (turns out the water food web isn't nearly as well understood). By the end of the seminar, they approached me about teaching some organics classes for them - I don't think I know jack compared to the masters here assembled, but they seemed to think I have something to offer. We'll see...
Here's our duck coop project we built:
View attachment 189757
All you need is a couple of Nemo Toads, a couple of carp and of course a Bass-O-Matic 77
Nemo Toads are a saltwater amphibian that can be harvested over at Aberdeen - toss a couple into the machine and puree. Add the carp (or trout, salmon, guppies, etc) and continue to puree.
Once it's finished add 4 tablespoons of Dolomite Lime and apply directly to the surface of the soil. Top-dress with FFOF (or Root's Organic) and hope for the best.
This is the method taught at Portlandsterdam University by Professor Jennifer Valley

My understanding of the Canadian situation is that PMRA (Canadian version of EPA) are cracking down on Neem Oil products that make insecticidal claims without being registered. I'm pretty sure you can use pure Neem Oil as long as you don't declare it as a pesticide. This link should explain it -http://pesticidetruths.com/2011/12/...-oil-will-be-taken-off-store-shelves-dec-2012
The same thing applies in the USA but they are a little more lax and allow companies to promote it as a "leaf shine".
I carry the same Neem Oil with a pesticide label - NimBioSys Neem Oil - http://www.nimbiosys.com. This cannot be sold in Canada.
Best wishes for the New Year.

DurdyWhat are some good talking points in convincing him a cold pressed high quality neem/karanja oil is the way to go?
