Soil Scout has launched the Happi100 oxygen sensor, a wireless sub soil oxygen sensor. The real-time monitoring solution allows turf professionals and growers to see the true impact of soil oxygen levels on plant root health.

“Healthy plant roots are not achievable without the presence of sufficient oxygen,” said Jalmari Talola, CEO of Soil Scout. “They can tolerate drought, they can cope in nutrient-poor soils, but oxygen uptake by roots is vital for plant respiration. Until now, we had no way to see if this process was under attack. Happi100 ends this today.”

“When soil oxygen levels dip below 10% for just four hours, plant root hair death occurs,” said Soil Scout Head of Agronomy Johannes Tiusanen. “Happi100 gives early warning of this happening, making it easier to prepare for, monitor, and mitigate impact from events like adverse weather and over irrigation.”

The sensor reads soil oxygen, moisture, and temperature from the same measurement point and seamlessly integrates with Soil Scout’s existing platform for a complete suite of underground trend data. This comprehensive approach allows professionals in agriculture and sports turf management to make more prescriptive interventions.

“Initial readings have shown that parts of my green quickly rebound to optimal oxygen levels within hours of heavy rain, whereas other parts can take up to a week to recover,” said Winston Golf Head Greenkeeper Erwan LeCocq. “I can now be more prescriptive in my aeration approach, significantly cutting down on the work needed to keep all my surfaces optimal.”

Pairing soil moisture balance with oxygen readings enables precise irrigation adjustments, helping to maintain root health in environments where aeration is limited before harvest.
