Case Studies

U.S. Midwest (Agricultural Co-op)

An agricultural cooperative in Iowa integrated Soil Ground Testing’s LoRaWAN-enabled soil moisture sensors across 15,000 acres. The system reduced irrigation water usage by 27% over a single season and increased soybean yield by 12%. Centralized dashboards allowed farm managers to respond quickly to moisture changes, improving efficiency.

Northern California (Vineyard Operator)

A vineyard deployed our Wi-Fi HaLow-enabled sensors to monitor root-zone moisture in 12 microclimates. Paired with weather data, this enabled tailored irrigation, resulting in a 22% reduction in water costs and healthier vine development during drought conditions.

Alberta, Canada (Municipal Infrastructure Monitoring)

A city engineering department used our multi-depth moisture arrays in combination with BLE Gateways to monitor moisture near retaining walls. The proactive alerts from sudden moisture shifts helped them prevent a potential slope failure during spring thaw, saving tens of thousands in potential repair costs.
