6.5 Soil Sample the Extremes

We dig into why skipping the lowest-yielding parts of a field can be the most expensive soil sampling decision you make. We lay out a simple “sample the extremes” plan that improves variable-rate fertilizer accuracy and helps put nutrients where they actually belong.
In this episode we discuss...
• reframing soil testing as nutrient placement, not just cost-cutting
• why red zones like hilltops, saline spots, and drown-outs often need sampling most
• how built-up phosphorus and potassium can hide in low-productivity areas
• using variable rate yield goals alongside soil test results for tighter fertilizer decisions
• choosing which management zones to sample and when to interpolate the rest
• splitting low zones into separate mods and sampling both when causes differ
• using ADMS to bring results back into zones and make educated interpolations
Tune in next time for a tiny bite of knowledge from GK Technology, where we have a map and an app for that.
