Identifying crop stress before visual symptoms appear remains a challenge in agriculture, particularly when issues develop below the soil surface. At Canola Week in Saskatoon, RealAgriculture spoke with Norm Janssen, business development lead for North America with Vivent Biosignals, about how plants respond to their environment through electrical signals.
Vivent Biosignals is a Swiss-based company that works in the field of plant electrophysiology. The company measures electrical signals that move up and down a plant, providing insight into how crops are responding to their environment. As Janssen says, “the signals are the plant telling us how it’s experiencing its environment… when it’s thirsty, when it’s hungry for various nutrients, [or] when insects have invaded various parts of the plant.”
Those electrical signals are driven primarily by the movement of calcium ions within the plant. By monitoring these signals, Vivent’s technology identifies stress caused by insects, disease, or root damage before visual symptoms are visible, Janssen says.
The technology was initially developed for research applications and has since expanded into commercial use. Early adoption has taken place in greenhouse environments, with additional applications including ground-truthing satellite imagery and supporting variable-rate water, fertilizer, and crop protection strategies. “There’s many, many applications for the use of this technology commercially and in research,” says Janssen.
