Master Cho’s method, in plain English.
Master Cho Han-kyu spent more than fifty years developing Natural Farming in Korea. Dr. Drake Weinert has studied KNF since 2007, first visited Master Cho in Korea in 2009, and is president of the Hawaiʻi Farmers Union’s Hawaiʻi Island chapter.
We teach Master Cho’s method in plain English, synthesized and simplified, with one name for each of the nine solutions: Food, Cleanser, Medicine, Structure, Reproduction, Minerals, Fuel, Protectors and Microbes.
Inputs are self-made; farmers are once again the masters of farming.Master Cho Han-kyu, Janong Natural Farming

Before you join
I’m new to KNF. Is membership for me?
Yes. Start with the nine solutions on Start Here, then bring your questions to the chat and the monthly meeting.
Does it renew? Can I cancel?
It renews once a year, and we email you before it does. You can cancel any time from your account; your membership stays active to the end of the year you paid for.
What happens to anything I pay above $60?
It’s a gift to the foundation, and it’s tax-deductible: we’re a 501(c)(3) public charity, EIN 84-3078726. Your receipt and welcome email show the $60 membership and the gift separately. Everyone gets the same access either way.
What’s free without joining?
The Hilo monthly meeting (2nd Tuesday, Komohana Research & Extension Center), the Office Hours archive, and searching the Q&A.
