Irrigation that follows the soil, not the calendar

Measured outcomes
- -28%
- Water use
- -19%
- Pump diesel
- +11%
- Yield per hectare
- 14
- Field hours saved weekly
Starting point
Irrigation ran on a fixed rotation regardless of rainfall. Diesel pumps were started manually, and blocks on sandy soil were consistently over-watered while clay blocks stayed dry.
“The pumps now run when the soil asks for it, and we can prove it.”
What we deployed
- LoRaWAN soil moisture and EC probes at three depths per block
- On-farm weather stations with rainfall and evapotranspiration modelling
- Pump and valve controllers with remote and rules-based actuation
- Block-level scheduling model reviewed weekly by the agronomy team
What changed
- Irrigation decisions moved from supervisor habit to soil evidence
- Pump faults surfaced as alerts rather than as dry blocks days later
- Water reporting for certification produced from system data
