We teach people to grow using what nature already provides.

Korean Natural Farming was developed by Master Cho Han-Kyu over more than sixty years of research and practice in South Korea. His approach is simple but radical: farmers can make their own biological inputs — from indigenous microorganisms, plant extracts, and fermented solutions — using materials found in their own environment. No factory, no supply chain, no dependency.

Master Cho's work spread across Asia, Africa, and Latin America, reaching millions of farmers. But English-language resources remained scarce and scattered. In Hawaiʻi, a small group of practitioners who had studied directly with Master Cho began teaching his methods through community workshops and weekly office hours.

The Pure KNF Foundation was established in 2019 to preserve this knowledge and make it accessible to anyone who wants to learn. What started as informal gatherings at the Komohana Research & Extension Center in Hilo has grown into a structured education, research, and certification program serving practitioners worldwide.

We carry forward Master Cho's vision: that farming should be simple, self-reliant, and in harmony with life.
