Challenging the “Way We Have Always Done It”: Agronomic Tough Pills to Swallow Part 1 with Crop Cast’s Sean Nettleton

In this episode of Rhizometrx, host Faith is joined by Sean Nettleton, host of the Crop Cast and Technical Agronomist at BW Fusion. Sean has been a key mentor in Faith’s journey away from traditional agronomy, and together they tackle the "hard pills to swallow" that many growers face when rethinking their management strategies. From admitting that grid sampling might be inducing variability to questioning high planting populations and nitrogen rates, this conversation is all about giving yourself permission to change your mind as you learn.

In this episode, you’ll learn:

The "Wrong" Way vs. The Better Way: Why shifting away from traditional methods isn't about admitting failure—it's about upgrading your toolkit with better information.

Grid vs. Zone Sampling: Sean's hot take on why grid sampling actually creates artificial variability, while zone sampling identifies the true, natural variability of the field.

The Population Paradox: Why more plants don't always equal more yield, especially in carbon-depleted zones, and how lower populations can lead to healthier plants and better ROI.

Nitrogen & The High Yield Myth: The misconception that high-yielding zones always need more nitrogen, and how over-applying nitrogen can block potassium uptake and lead to late-season stalk issues.

Be Curious, Not Judgmental: The importance of staying open to new data and tweaking your approach year after year, rather than treating any agronomic practice as set in stone.
