Farm app with field records
Hypothetical. Not a client, not a result.
// The problem
A vegetable and berry farm keeps its spray, fertiliser and harvest records in notebooks, and getting ready for a food safety audit or a buyer's questionnaire takes days.
// What we would build
A web and mobile app where crews log field work at the field, offline, against a map of fields and blocks, with product rates, pre-harvest intervals and re-entry times checked as they log, and records ready when the auditor arrives.
// What is in it
- Seed, fertiliser and chemical lots labelled with QR codes, and machinery located by GPS
- Map of fields and blocks with crop, variety and planting dates
- Spray and fertiliser logs with product, rate and the weather at the time
- Pre-harvest intervals and re-entry times checked before a block is harvested or entered
- Harvest records with lot codes for traceability
- Works offline in the field and syncs at the yard
- Exports in the formats your CanadaGAP auditor and buyers ask for
