Satellite pass to field prescription in under a day.
Harva combines three data streams, applies a zone-level model, and sends a prioritized action list every Monday morning before you reach the field.
Satellite, sensors, weather: one view from three streams
Each layer fills gaps in the others. Harva combines all three so one missing signal does not skew the prescription.
Satellite Imagery
Weekly multispectral passes show greenness variation, canopy density, and zone-level stress across every acre.
In-Field Sensors
Soil moisture, temperature, and EC sensors add subsurface context satellite views cannot provide.
Hyperlocal Weather
Station-level precipitation totals and temperature forecasts inform irrigation and fungicide timing thresholds.
The model scores each field zone weekly, not seasonally
Season-long calendars can miss the weeks that matter most. Harva re-scores every management zone weekly, keeping the prescription aligned with what the field looks like right now.
Ingest and align
Within hours of collection, new satellite tiles, sensor readings, and weather logs are pulled and georeferenced to your field boundaries.
Zone scoring
Each management zone gets a composite stress score based on greenness deviation, soil water deficit, and disease pressure probability.
Prescription generation
Scores become action thresholds: where to irrigate, where to scout, and which zones can wait another week.
Calibration feedback
Field notes and scouting outcomes return to the model, improving zone scoring accuracy for your fields over time.
Monday prescription, ready before your morning walk
No dashboard login before your morning walk. Harva sends the week's priority actions in a formatted table, ready to use.
| Field | Acreage | Water (in) | Nutrient Flag | Spray Alert |
|---|---|---|---|---|
| Field A | 520 ac | 0.8 | Normal | No |
| Field B | 380 ac | 1.2 | Increase | No |
| Field C | 710 ac | 0.5 | Normal | Yes |
| Field D | 290 ac | 0.9 | Normal | No |
Works alongside what you already own
Keep your guidance system and VRI hardware. Harva uses their data and returns prescriptions in formats your tools accept.
Soil sensors
Works with standard Modbus and cellular-enabled soil moisture and EC sensor networks.
Prescription export
Export prescriptions as shapefile or CSV for most variable-rate application controllers.
Field data import
Upload field boundaries and historical yield maps by CSV or KMZ to provide field context on day one.
Email delivery
A prescription summary reaches your inbox every Monday morning, ready to share with your agronomist or application crew.
