Biological Farming Roundtable

Host Nakala Maddock sits down in Brocklesby with fine wool Merino producers Ron and Liz Koschitzke, a couple whose shared passion for soil health has completely reshaped their farm.

In this episode, Ron and Liz unpack the practical steps that regenerated their soils, and the results speak for themselves.

This episode goes straight to the heart of what regenerative agriculture really means. Nakala sits down with Luke Harrington, founder of Re Gen Farming and a practitioner with more than 20 years in the regenerative space to explore why true regeneration isn’t just about soil. It’s about people.

Luke shares his passion for rebuilding farming families, strengthening rural communities, and creating systems that allow farmers to thrive across generations. Together, they unpack practical, profitable regenerative farming approaches that support profitability and protect yield.

From biological inputs to whole farm thinking, It’s a practical, grounded look at how biological systems drive yield, resilience, and simple steps to begin your transition.

A must listen for farmers who want to grow more than crops — they want to grow a future.

In episode 50 of the Biological Farming RoundTable, host Nakala Maddock sits down with ECTOL founder and ag scientist John McKay. John walks us through the discovery of osmo protectants in marine algae, the first commercial frost protection applications in Australia, and how foliar nutrition evolved from horticulture into broadacre cropping and pasture systems. Along the way, he unpacks the big picture: why nutrient inefficiency and crop stress quietly and significantly robs agriculture of their true potential yield, why nitrogen efficiency matters more than ever, and how products like ECTOL are designed to support healthier, more resilient plants without the boom and bust cycle of heavy urea use.

In Episode 49 of the Biological Farming RoundTable host Nakala Maddock is rejoined by David Hardwick from Soil Land Food and Luke Harrington from Re-Gen Farming. This episode is part two of the Managing Regenerative Transition series, where the team unpack the types and stages of transition or change, what to expect and where to go to get resources and support. Luke and David share their top tips to help you regain control of your farming operation.
