The challenge
Aurelia Grain Cooperative's agronomists wrote fertilizer prescriptions from soil samples taken every four years and applied them uniformly across whole fields. Members paid for inputs their best acres did not need while their weakest acres stayed weak, and nobody could show which practice changes actually moved yield.
The approach
GeoGarmeux set up a growing-season monitoring subscription: weekly satellite imagery across all 180,000 member acres, processed into vegetation-index and zone maps in GeoGarmeux Atlas. Agronomists now write variable-rate prescriptions from current-season zones, and harvest yield maps flow back in to close the loop on every decision.
The results
- 18% improvement in input efficiency across enrolled acres
- 180,000 acres monitored weekly through the growing season
- 400 member operations with field-level zone maps in the first year
“For the first time our members can see the payoff of a decision on a map, field by field, season over season.”
