In this episode ofCrop Cast, host Sean Nettleton and Mason Claude take a deep dive into one of agriculture’s most persistent challenges: the oversimplification of agronomy. They explore why common “rules” in fertility management, like chasing perfect pH or part-per-million numbers, often lead farmers astray. Mason breaks down why agronomy is less a precise science and more an “art” built from overlapping disciplines — soil physics, chemistry, biology, and meteorology — that must be interpreted with context, not formulas. Together, they bust long-standing myths around lime, soil balancing, and fertilizer response curves, showing how over-liming, ignoring biological activity, or fixating on lab data can actually harm soil function. Instead, they call for a more holistic, data-driven approach that values living soil systems, enzyme activity, and carbon cycling as the foundation for sustainable yield. The episode balances hard agronomic science with honest, farmer-to-farmer perspective, challenging listeners to rethink what “soil health” and “fertility” really mean.
