An agribusiness or farmer cooperative wants one platform where growers record field work, spot crop problems early and use water and inputs more precisely. This blueprint shows how we combine an offline-first mobile app, field sensors, satellite imagery and AI models. Recommendations stay practical and farmers or agronomists make the final call.
This is a solution blueprint: a representative engagement showing how we approach this kind of project. It is not a specific client story.
Farming decisions are time-sensitive and local. A fungal disease that starts in one corner of a field can spread within days. Irrigating on a fixed schedule wastes water in a wet week and stresses crops in a dry one. Much of the useful information already exists: soil moisture sensors, weather forecasts, free satellite imagery and the farmer’s own observations. But it sits in separate apps, spreadsheets and notebooks, and rarely reaches the person in the field at the right moment. The platform we design brings it together and turns it into timely, practical advice.
Farmers and field staff use the app on a phone, often with gloves, in bright sunlight and with poor coverage. We build it in Flutter with an offline-first data layer. Field records, photos, tasks and maps are stored on the device and synced when a connection returns, with conflict handling so two people editing the same field don’t overwrite each other. The interface uses large touch targets, high contrast, local languages and units, and voice notes for quick observations.
A grower photographs a suspicious leaf and gets an answer in seconds. A compact image model runs on the device with TensorFlow Lite for an instant first check, even offline, and a larger server-side model refines the result when the phone reconnects. The app shows the likely disease or pest, how confident the model is, and what to check next. Low-confidence results and anything that would trigger a treatment are flagged for an agronomist to confirm. The models are trained and evaluated on labeled images for the crops and regions the platform serves, and every confirmed case improves the next version.
Free Sentinel-2 satellite imagery covers each field every few days. The imagery pipeline removes cloudy pixels, clips images to field boundaries stored in PostGIS, and calculates vegetation indices such as NDVI. Those indices highlight areas that are stressed, waterlogged or developing unevenly compared with the rest of the field. Growers get a crop health map and a short list of zones worth walking to, instead of a raw image.
Soil moisture and weather sensors report through AWS IoT Core into a time-series store. The irrigation advisor combines current soil moisture, the weather forecast and the crop’s growth stage to suggest when and how much to irrigate, and explains why. The same signals, together with satellite trends and field records, feed season-to-date yield forecasts that help with planning, storage and sales. Recommendations are advice with reasons attached, so the farmer stays in control.
Cooperatives, input suppliers and agribusinesses serve many farms at once, so the platform is multi-tenant from the start. Each organization sees only its own farms, and each farm’s fields, records and sensor data are isolated at the database level. Agronomists can be granted access to several farms with explicit consent. Farm data belongs to the farmer, can be exported, and is never shared with third parties without permission.
We plan around the growing season. A pilot with a small group of farms runs through one full season, starting with field records, offline sync and photo diagnosis, then adding sensors, satellite maps and irrigation advice as data builds up. Agronomists review model outputs throughout the pilot, and we track model accuracy on a held-out set of confirmed cases before widening the rollout. See our web and mobile app development approach for offline-first apps, and our cloud services for the IoT and data platform behind it.
If you are an agribusiness, cooperative or AgTech startup that wants to put AI and sensor data in growers’ hands, in a form they will actually use in the field, this blueprint is a practical place to start. Explore our custom software development service or talk to us about your farm platform.
