17. Variable Rating Herbicides with Kyle Okke Pt. 3

We map residual herbicide rates with field truth, not guesses, turning five-zone soil maps into targeted prescriptions that cut injury and hit weed spawn sites. We weigh OM, pH, texture, and landscape to protect sensitive crops now and keep rotations flexible next year.In this episode we discuss...• base maps from precision soil sampling and scouting knowledge• modded zones for unique poor areas and weed hotspots• organic matter, carbonate, and color as soil clues, not absolutes• extreme pH swings shaping efficacy, injury, and carryover• decision framework from damage mitigation to suppression• variable rates to protect sensitive crops and rotations• SmartFirmer OM layers and controller-friendly rate steps• lidar, soil series, and as‑applied maps to refine zones• practical limits of sensors and when algorithms help• closing insights and where we push rates or back offMissed the first two parts of this episode?
