CropSense
CropSense is a precision agriculture platform connecting soil sensors, weather stations, and satellite imagery to provide actionable insights for farm operators. It ingests IoT telemetry from 1,200+ field sensors, runs agronomic models, and delivers field-level recommendations through a mobile-friendly dashboard.
What CropSense set out to fix
Data-driven field management for precision agriculture
A multi-farm operation spanning 8,400 acres across three regions was generating enormous volumes of sensor data from soil moisture probes, weather stations, and satellite imagery subscriptions, but none of it was connected into an operational decision framework. Irrigation schedules were based on calendar rules rather than soil conditions. Fertilizer applications followed uniform rates rather than variable field needs. Pest interventions were reactive, triggered by visible crop damage rather than early environmental indicators. The data existed to farm more precisely, but no platform unified it into recommendations operators could act on.
Sensor data without integration produced no decisions
The operation had invested heavily in sensing infrastructure, but without a platform to unify, model, and interpret the data, sensors were generating noise rather than intelligence. Field managers were still making decisions the same way they had before the sensors were installed.
Disconnected sensor networks with no unified view
Soil moisture data lived in one vendor portal, weather data in another, and satellite imagery in a third. Field managers had to mentally correlate readings across three separate interfaces to form a picture of field conditions, which they rarely had time to do.
Reactive crop management instead of predictive intervention
Without models that combined sensor signals into forward-looking recommendations, all interventions were reactive. By the time drought stress was visually apparent, yield loss had already begun. By the time pest damage was spotted during a field walk, the infestation was established.
Water waste from calendar-based irrigation schedules
Irrigation ran on fixed schedules regardless of actual soil moisture levels, recent rainfall, or upcoming weather forecasts. Some fields were overwatered while adjacent fields were underwatered, and the operation's water cost was 31% higher than data-optimized benchmarks.
What reactive irrigation management looked like
A field manager noticed wilting in a soybean field during an afternoon inspection. Soil moisture probes in that field had been reading below the stress threshold for three days, but the data was only checked weekly. The irrigation system ran on a Monday/Thursday schedule regardless of readings. By the time supplemental irrigation was applied, the crop had experienced four days of moisture stress during a critical growth stage, reducing yield potential by an estimated 8% for that field.
Soil moisture optimization tracked across the growing season
CropSense's irrigation recommendations maintained soil moisture within the optimal range consistently throughout the growing season, eliminating both the drought stress dips and overwatering peaks that characterized calendar-based scheduling.

Twelve-month build from sensor audit to full-season operation
Structured as an agri-tech program: sensor network assessment, IoT pipeline construction, agronomic model development, field validation, and full-season operational deployment with continuous model refinement.
Sensor network audit and data architecture
Cataloged every sensor type, communication protocol, and data format across the operation's three regions. Designed the multi-tenant data architecture to handle heterogeneous IoT telemetry at the volume and frequency required for 15-minute field-level updates.
IoT ingestion pipeline and data normalization
Built the telemetry ingestion system supporting MQTT, HTTP, and proprietary sensor protocols. Implemented data normalization, quality scoring, and gap-filling algorithms to produce clean, consistent field-level time series from raw sensor feeds.
Agronomic model engine and recommendation system
Developed the model execution framework that combines soil moisture, temperature, humidity, rainfall, satellite vegetation indices, and historical yield data to generate irrigation, fertilization, and pest management recommendations at the field level.
Dashboard build and field validation
Built the responsive field management dashboard with map-based visualization, recommendation cards, and alert notifications. Ran a two-month field validation trial across six pilot fields to calibrate model accuracy against observed outcomes.
Full-season deployment and model refinement
Rolled out across all 8,400 acres with field manager training, established feedback loops for model refinement based on observed outcomes, and implemented the continuous learning pipeline that improves recommendations with each season of data.
Three field situations the platform handled
Early Drought Stress Intervention
A 200-acre corn field was approaching a critical tasseling stage during a period of below-average rainfall. Calendar-based irrigation was not scheduled for another two days, and the field manager had not yet inspected that section of the operation.
CropSense detected soil moisture dropping below the crop-specific stress threshold 36 hours before the scheduled irrigation. The system combined the moisture reading with a five-day weather forecast showing no expected rainfall and pushed an urgent irrigation recommendation to the field manager's mobile device.
Supplemental irrigation was applied within six hours of the alert. Post-season yield analysis showed the field performed within 2% of optimal, compared to a neighboring unmonitored field of the same variety that experienced a 12% yield reduction from the same dry period.
Pest Pressure Early Warning
Soybean aphid populations can explode rapidly when temperature and humidity conditions align, but visual scouting only detects infestations after populations are established and economic damage has begun.
CropSense's pest risk model identified a high-probability aphid pressure window based on the convergence of rising temperatures, elevated humidity readings from field weather stations, and satellite-detected vegetation stress patterns in adjacent fields. The system issued a scouting recommendation three days before any visible infestation.
Targeted scouting confirmed early aphid presence in two of seven flagged fields. Treatment was applied at the economic threshold rather than after visible damage, reducing insecticide cost by 40% compared to the previous season's reactive application.
Variable-Rate Irrigation Scheduling
A 400-acre irrigated field had significant soil variability, with sandy sections draining quickly and clay-heavy sections retaining moisture. Uniform irrigation rates overwatered the clay zones while underwatering the sandy zones.
CropSense mapped the field's soil moisture variability using sensor placement analysis and historical drainage patterns, then generated zone-specific irrigation prescriptions that the operation's variable-rate irrigation system could execute directly.
Water usage on the field decreased by 28% while yield uniformity improved by 15%. The sandy zones no longer showed drought stress, and the clay zones no longer showed waterlogging symptoms during wet periods.
What shaped the platform architecture
IoT data pipelines required tolerance for unreliable sources
Agricultural sensors operate in harsh environments with intermittent connectivity. The ingestion pipeline was designed to handle out-of-order delivery, duplicate transmissions, extended offline periods, and sensor drift. Data quality scoring ran on every reading, and gap-filling algorithms maintained continuous field-level time series even when individual sensors were temporarily offline.
Agronomic models needed local calibration, not universal training
Crop response to soil moisture, temperature, and nutrient levels varies significantly by soil type, microclimate, and variety. We built the model framework to support field-level calibration using each location's historical data, rather than relying on generic agronomic lookup tables. Model accuracy improved 34% after the first season of local calibration feedback.
Fifteen-minute data refresh required a streaming architecture
The operation needed field conditions updated every fifteen minutes during the growing season to support time-sensitive irrigation and pest management decisions. A batch ETL approach could not meet this cadence. We implemented a streaming architecture using Apache Kafka for telemetry ingestion and incremental model re-evaluation, ensuring fresh recommendations were always available.
