Harvora™ model-card brief
Harvest timing and maturity planning model card
This model card documents the method, evidence target and limitations for harvest timing and maturity planning. The measured target is a maturity-threshold crossing, not an actual pick date. Orchard maturity and harvest logs aren't in the field dataset yet — logged harvests are precisely what sharpens this surface from regionally true to block-true.
Direct answer
What this supports
Harvest readiness is reported as days-to-readiness with an uncertainty band, anchored to thermal-time accumulation and each block's own season — a planning date that sharpens weekly, not a promised pick date.
Intended for New Zealand growers, technical partners, lenders and insurers.
Evidence and method
How the signal is formed
Growing-degree-day accumulation is projected forward from observed weather with a Monte Carlo distribution and read against a crop-specific maturity threshold.
Evidence grade: ESTIMATE
Weather-benchmark measured today; every grower outcome logged in the product feeds the field benchmark it is measured against next.
Boundary
How to read this evidence
The measured target is a maturity-threshold crossing, not an actual pick date. Orchard maturity and harvest logs aren't in the field dataset yet — logged harvests are precisely what sharpens this surface from regionally true to block-true.
