How do you keep an arable farming business profitable in an environment of changing markets, tightening regulations, and unpredictable weather? In this episode, Matt and Wade are joined by David Birkett, Canterbury arable farmer, to explore how he uses data, irrigation, and a simplified cropping system to make better decisions and build resilience into his operation. David shares how his rotation balances productivity with practical constraints like harvest timing, soil traffic, and seasonal risk.

The team unpack David’s approach to nutrient management, including organic matter testing, nitrogen mass budgeting, and simple on-farm strip trials to validate decisions. They also dive into precision agriculture, discussing the value of yield monitoring, satellite imagery, and variable rate applications, and why understanding the numbers remains critical for decision-making. David also shares insights from his governance roles with FAR and Federated Farmers, covering seed certification, traceability, biosecurity, research funding, and the future of New Zealand’s arable sector.
