Free to start. No credit card required.
Example decision briefing
Three priorities, linked to available field evidence.
When available, ZarSage surfaces sources, assumptions, confidence, and missing evidence for review.
- 01
Spray timing
Compare fieldwork timing with forecast wind and rain risk.
- 02
Scouting
Flag a block for review when satellite vegetation falls below its seasonal baseline.
- 03
Water
Recheck irrigation when forecast rainfall may cover part of the deficit.
