ULC KNF vs JADAM
I was wondering a couple things. By ULC do you mean Ultra Low Cost as in the JADAM style?
Also, is the use of Jadam Sulfur (ultra low-cost pest control) applied according to Jadam principles certifiably organic in the US?
Top answer
JADAM has copyright on some certain terminology, though the recipes are free and open source and so old that they are impossible to patent, so to avoid the wrath of that terrible organization, KNF Support has chosen to call these solutions Ultra Low Cost or ULC for short.
The ULC KNF Pest Solutions all fall into the list of OMRI approved materials that can be used for organic practices in the United States of America Inc. You will have to check with your individual certifier once you start mixing things.

Drake calls JADAM a cheap, easy entry point. He says KNF is the umbrella that includes JADAM. Master Cho's solutions sit a level above, but are harder to make and apply correctly. (Office Hours Ep. 125, 39:34)
JADAM is Korean natural farming too. (Office Hours Ep. 42, 44:47) The "disgustingly cheap" KNF is Cho's JADAM microbe solution: water, dirt-filled socks, potato-filled socks, and a bit of salt, fermented in a trash can. (Office Hours Ep. 106, 48:07)
Drake compares JADAM to a Toyota: simple and forgiving. He compares Cho's method to a Lamborghini: high precision but unforgiving. (Office Hours Ep. 90, 51:50)
The library does not explain the ULC name. It also says nothing about JADAM Sulfur or organic certification in the US.

Thanks for the clarification. Hahaha I like that USA Inc line you threw in there. I figured copyright had something to do with the terminology. The mixing component is interesting. I can see how having several different herbal solutions in a pesticidal program along with wetting agent and red clay sulfur could get pricey having each useful combination approved by a certifying body.
