Satellite Crop Advisory in the Farmer's Own Language
Satellite Crop Advisory delivers per-field vegetation and water indices from free Sentinel-2 and NASA HLS imagery, translated into plain-language irrigation and disease advisories in eight Indian languages. Every recommendation cites an agronomic standard, FAO-56 for evapotranspiration, TOMCAST for disease risk, and each derived record is sealed in a per-field SHA-256 hash chain.
Hindi, English, Marathi, Tamil, Telugu, Kannada, Bengali and Gujarati, advisories farmers can act on without translation.
Hash-Chain-Sealed Records
Every advisory derivation is appended to a per-field SHA-256 hash chain, auditable evidence, not marketing claims.

Which agronomy models power the advisories?
FAO-56 Penman-Monteith evapotranspiration (Hargreaves-Samani where local weather permits) for irrigation. TOMCAST Disease Severity Value for vegetable disease risk. See our citation registry.
In which languages are advisories delivered?
Eight Indian languages: Hindi, English, Marathi, Tamil, Telugu, Kannada, Bengali and Gujarati.
