The current instability in the Middle East is once again putting global fertiliser supply under pressure. Highlighting just how exposed food systems like Australia’s can be when they rely heavily on imported inputs.
This isn’t about criticising fertiliser use. For many farmers, it has been an essential tool. But moments like this invite a bigger question: what if there are other ways to build resilience into our farming systems?
In this clip, Dianne Haggerty shares how, through Natural Intelligence Farming, cereal crops are being grown without the addition of synthetic NPK (nitrogen, phosphorus, potassium). Not by removing nutrients from the equation, but by changing how they are cycled.
In a biologically active soil, nutrients aren’t simply “added”. They are continuously transformed, mobilised and regenerated.
Nitrogen, for example, can be fixed from the atmosphere by free-living and symbiotic microbes, then stabilised in organic forms within the soil. Phosphorus and potassium, often abundant but locked in unavailable forms, are solubilised by bacteria and fungi that release organic acids and enzymes, making them accessible to plants when needed.
At the centre of this system are mycorrhizal fungal networks, extending the effective root system of plants and facilitating the exchange of nutrients in return for carbon. Alongside them, a vast microbial community decomposes organic matter, recycles nutrients, and rebuilds soil reserves over time.
At the same time, this biology rebuilds soil structure, creating a sponge that holds more water, buffers dry periods, and improves plant resilience. Moist, well-structured soils can also moderate temperature swings, helping reduce frost impact.
The result is a system where crops are not mining the soil, but participating in a living cycle! One that can maintain and even increase nutrient availability while producing food.
Resilience in agriculture may not come from adding more inputs, but from rebuilding the natural intelligence of the soil itself.
