We explore using precision agriculture to variable-rate apply residual herbicides using soil-driven maps to reduce crop injury on sensitive zones while maintaining strong weed control. Kyle Okke joins us to explain why OM, pH, and texture can set the rate and how sprayer mechanics affect success.

In this episode, we discuss

• Specialty crops that rely on pre-emerge residuals
• Resistant weeds driving need for fall residual applications
• Soil variability across landscape positions
• Reading labels and guidance on applications based on soil OM, pH and texture
• Diagnosing sunflower and pea herbicide injury patterns
• Pre- versus Post-herbicide application nuance and resistance risk
• Carrier volume (GPA: gallons per acre) as a rate knob
• Coverage demands for contact herbicides
• Sprayer pressure, droplets, and nozzle behavior
• When to split passes versus going across a field once

At GK Technology, we have a map and an app for that!
