Cows wearing e-collars help boost potato yields in P.E.I. pilot project

On Canada's Prince Edward Island, a new pilot project is using electronic collars on cows to improve potato yields and soil health. The collars create virtual fences, allowing farmers to control where cattle graze and spread manure, returning nutrients and organic matter evenly across fields. The approach, known as rotational grazing, helps build richer soil that retains moisture and supports long-term crop productivity. Funded partly by Canada's On-Farm Climate Action Fund, the project benefits both beef and potato farmers by sharing land use. Researchers expect early soil results next year, though major yield gains may take over a decade.
