The 1% Soil Change That Supercharges Your Farm

In this clip from the EFA podcast, Ewan Campbell and Stephen Brunton break down the real numbers behind soil carbon, organic matter, and nutrient availability — and reveal why most farmers are leaving tens of thousands of dollars of fertility trapped underground.

Ewan explains why a 1% increase in organic matter equals 15 tonnes of soil, hundreds of kilos of nitrogen, and huge boosts in phosphorus and sulphur — all without buying synthetic inputs. He also challenges mainstream ideas about root-based carbon storage, arguing that cyanobacteria, not plant roots, are the real engine behind NZ’s soil carbon cycle.
