Frequently asked questions
Where can I learn more about KNF?
The best place to start is a course on a working farm, where you can see and make the inputs yourself. Books by Cho Han-Kyu and Chris Trump are widely available. The Origins page on this site outlines the lineage and the underlying ideas. Many Irish farmers also learn through visits to peers who are already practising.
What are the biggest misconceptions about KNF?
The most common is that KNF is hippy or unscientific. In reality, it is highly methodical, with precise timing, measurements, and sequences. Another is that it only suits small farms. Chris Trump applied KNF across hundreds of acres of macadamia in Hawaii. The method scales when the thinking is understood.
Is KNF more expensive than conventional farming?
Significantly cheaper over time. Farm-made inputs cost a fraction of synthetic fertilisers, and reduced veterinary and input bills compound year over year. Initial setup requires time and learning rather than capital. Most farms see a clear cost reduction within the first full season of consistent practice.
Can KNF work in Irish conditions?
Yes, with adaptation. Irish farming conditions differ significantly from Korea or Hawaii, where the method was developed and scaled. The principles travel well; the timing, materials, and application require local translation. Irish farmers are now applying KNF to dairy, beef, sheep, tillage, and market garden operations with measurable results.
How is KNF different from organic farming?
They overlap but are not the same. Organic certification is a regulatory framework that restricts certain inputs. KNF is a practical method for building soil biology and farm-made inputs. Many KNF farms qualify as organic, but you can practise KNF on a conventional farm without certification. The two systems can work together or independently.
Is there scientific evidence for KNF?
KNF is grounded in soil microbiology and plant physiology. Indigenous microorganisms, lactic acid bacteria, and fermented inputs all have measurable effects on soil structure, nutrient availability, and plant health. The method predates much of the formal research, but the underlying biology is recognised in agricultural science.
What is Korean Natural Farming?
Korean Natural Farming (KNF) is a system of farming developed by Master Cho Han-Kyu in Korea from the 1960s onward. It works by cultivating beneficial microorganisms and making farm inputs from local materials. The method reduces dependency on synthetic fertilisers and pesticides while building soil biology over time.
Is there a newsletter or mailing list?
The newsletter goes out roughly once a month with course dates, field updates from the farm, and seasonal notes on what's happening in soil and pasture. It is the best way to stay informed about upcoming courses and events. You can subscribe via the form at the bottom of any page.
Do you partner with other organisations?
Yes. We collaborate with agricultural colleges, sustainability groups, and farming organisations across Ireland and internationally. We are also open to partnering with farms, cooperatives, and food brands committed to soil health. Email us with proposals or enquiries.
Who runs Natural Farming Ireland?
Natural Farming Ireland was founded by Tom Stack, a dairy farmer from south Limerick who studied with Chris Trump in 2019. It is now run by a small team of practitioners, teachers, and farmers committed to making natural farming accessible in Irish conditions. The Team page lists everyone currently involved.
Where is Natural Farming Ireland based?
Natural Farming Ireland is based in the west of Ireland, with the main demonstration farm in south Limerick. Courses are run at this farm and at partner farms across the country. The exact location of each course is shared with confirmed participants on booking.
How do I contact Natural Farming Ireland?
The best way to get in touch is by email at hello@naturalfarmingireland.com. We respond within two working days. For urgent course-related queries within a week of a course start date, please mark your email as urgent in the subject line.
