Thomas Stack is a dairy farmer from Co. Limerick. Having taken over the family farm in 2012 and farming conventionally for a few years, he decided something had to change. He embarked on an ambitious journey to transform his farm into a system that is resilient to environmental and financial shocks.

Thomas transitioned to organic farming in 2018 and since then he has adopted the Korean Natural Farming method. This regenerative approach uses indigenous microorganisms (IMO) to create fertile soils that produce a high output without the use of synthetic fertilizer, herbicides or pesticides. “You can’t see these microbes. The only way you can see them is under the microscope and they’re the most powerful thing in the world...to see how they have transformed my farm in a year and a half – it’s mind-blowing.” Thomas creates IMO solutions that are highly rich in nutrients and enzymes, he sprays these solutions on the land, working in tune with the nutrient cycle of the plants.

Thomas milks 60 dairy cows on virtually no external inputs. His cows are entirely grass-fed and he produces high quality organic milk. He creates his own nutritional supplements for his animals using only natural inputs and processes. “I use the land and nature to produce all my inputs on the farm and to enhance the soil biology". Having a huge interest in nature, Thomas has planted over 1000 native trees on the land already and has plans to plant many more trees to support biodiversity and encourage more wildlife back to the farm. He regularly hosts farm visits for those interested in learning more about this dynamic farming system.
