Advanced Soil & Sap Testing: How to Diagnose Nitrogen, Biology & Chloride Problems | Clint Frese

Clint Frese breaks down how he uses soil and sap testing to diagnose the real limiting factors on a farm — not guesswork, not marketing claims, actual data. This talk covers biological soil testing, sap analysis, nutrient mobility, anion/cation ranking, nitrogen conversion efficiency, herbicide stress, and how carbon (fulvic acid) products like Backbone and N-Plex are used to correct nitrogen conversion problems in the field. If you're managing irrigated acres, dry land, or a mix of both, this is a deep dive into putting your farm into management "buckets" and using real diagnostics — not bushels promised on a bag — to find where you're actually losing yield.
