Agriculture dashboard

A soil-water Twin of a Central Valley orchard envelope: Hargreaves ET₀, FAO-56 Kc and stress, a mass-conserving bucket, and irrigation as a declared intervention. Climate is generated at Fresno latitude. It is not CIMIS, and it is not agronomy advice.

Predictive and experimental rungs stay open. A useful scenario is not a yield forecast.
