facing the challenges of open field management
Fields Are Variable by Nature and Control Needs to Match
Open fields introduce complexity that fixed schedules can't manage. Soils vary within the same farm. Pressure and flow shift over long distances. Weather-driven demand changes daily. When irrigation and fertigation run on assumptions instead of real data, resources reach the wrong place at the wrong time, and crop response becomes unpredictable.
Talk to an EngineerThe Expensive Soil Variability Blind Spot
Soil composition, slope, and organic matter shift constantly across a single field. Running a uniform irrigation schedule ignores this reality—over-watering heavy zones while starving sandy patches. The result is an uneven crop stand and yield gaps that fixed timers can't see or fix.
The Unseen Hydraulic Friction Factor
Pressure and flow degrade naturally across long pipe runs and elevation changes. Without real-time hydraulic data, emitters at the far end under-deliver while the near end floods. Manual pressure adjustments can't compensate for this dynamic loss, creating chronic uniformity issues.
The Cumulative Weather Response Lag
Evapotranspiration rates change hourly with cloud cover, wind, and temperature. When irrigation is scheduled days in advance, it misses peak crop demand or applies water right before a rain event. The crop endures unnecessary stress while resources are wasted on reactive drainage.
The Chronic Fertigation Segregation Trap
When water and nutrients are injected separately, they don't always arrive together in the root zone. Without coordinated delivery, nutrients can be leached below the root zone by a previous irrigation cycle, or left stranded in dry soil where roots can't access them.
Our approach includes
Control at Open Field Scale
Farmnet open field systems manage irrigation, nutrition, sensing, and hydraulic performance as one coordinated process where real-time data directly drives field decisions instead of fixed schedules.
Irrigation Control
Centralized, two-wire, or long-range wireless valve control adapted to field topology and infrastructure scale.
Nutrition Delivery
Fertilizer injection synchronized with irrigation flow for accurate and uniform nutrient application.
Root-Zone Water Status
Soil moisture and water availability continuously guiding irrigation and fertigation timing.
Climate & ET Demand
Weather data and evapotranspiration models aligning water supply with real crop demand.
Hydraulic Performance
Flow and pressure monitoring maintaining uniform distribution across long field distances.
Monitoring, Visibility & Alarms
Continuous system feedback with alerts when conditions deviate from operational targets.

Will it work across our field distances?
Wired, two-wire, and LoRa wireless networks reach up to ~4.5 km. We design for your infrastructure.
Can it handle soil variability across zones?
Sensor-driven logic adapts timing and dosage to real conditions—not fixed zone averages.
What about reliability in the field?
Hydraulic monitoring and alarms detect deviations before they affect distribution or crop response.
Can it scale as we expand?
Architecture is built for large-area control and scales without losing coordination.
