In part two of our soil testing series, we go deeper into real-world soil sample interpretation and how to turn those numbers into actionable fertility recommendations. We break down a Mehlich-3 soil test, discuss variability across zones, and explain how factors like pH, CEC, organic matter, and base saturation influence nutrient availability and crop performance.
We also dive into phosphorus variability, variable-rate strategies, and how extraction methods impact what your soil test is really telling you. Plus, we shift the conversation beyond N-P-K — highlighting the role of secondary and micronutrients like zinc, manganese, and iron, and how they influence ROI and yield potential.
From crop-specific micronutrient needs to understanding P-to-zinc ratios, tissue testing, and yield-goal-based fertility planning, this episode focuses on building a more balanced, data-driven nutrition program. The takeaway: soil tests aren’t just numbers — they’re a roadmap to better decisions, stronger crops, and more consistent returns.
