In this episode of RhizoMetRx, host Faith is joined by Nebraska natives Kyle Olson and Chase Perry to dismantle the "grid sampling" status quo. Together, they explore the shift to zone management through the Baseline protocol and share real-world examples of "ground truthing" soil data.

Listeners will gain insights into why nature doesn't grow in perfect squares, how to interpret advanced soil metrics like WEOC and PSAT, and practical strategies for improving nitrogen efficiency and farm profitability.

In this episode, you’ll learn:

The Grid Sampling Disconnect: Why traditional grid sampling fails to capture biological and physical reality compared to zone management based on water-holding capacity and elevation.
Ground Truthing the Data: How visual field indicators—such as weed pressure lines, cover crop establishment, and corn stalk diameter—consistently confirm zone boundaries.
Indicator Test Metrics: The difference between H3A (plant-available) and standard PPM, and how to use Phosphorus Saturation (PSAT) scores to decide between banding, broadcasting, or cutting starter fertilizer.
Carbon-Nitrogen Balance: The critical role of Water Extractable Organic Carbon (WEOC) and why overloading nitrogen on low-carbon soils can lead to late-season disease and poor stalk quality.
Efficiency Over Yield Chasing: Strategies to identify where you can cut unnecessary inputs without sacrificing yield, allowing you to reallocate dollars to the zones that need them most.
