15.5 Precision Composite Soil Sampling Explained
Description
We unpack why “precision composite soil sampling” isn’t a contradiction and show how GPS-marked points turn an old method into a reliable trend tool. We cover workflows, gear, timing, and when shifting results should push you toward zones.
In this episode we discuss
• Pre‑GPS composite sampling and its limits
• Marking exact GPS points for repeatability
• Keeping post‑harvest or spring timing consistent
• Tracking year‑over‑year P, K and pH trends
• When composites signal a move to zones
• Benchmarks versus wider composite coverage
• Core counts for quarters and half sections
• Gear tips: external GPS pucks and apps
• Faster fieldwork once points are mapped
• Starting with GK Field Mapper and ADMS exports
