The article highlights a significant shift in farming practices on Prince Edward Island, Canada, where potato growers have doubled the acreage of cover crops, leading to healthier soil and potential additional income. According to the P.E.I. Potato Board, over half of the potato-growing acres now have cover crops, with benefits including improved yield, reduced erosion, and better soil health. Some farmers are also seeing extra income by harvesting cover crops like winter wheat. However, there is a push to encourage farmers to leave cover crops in the field for multiple years to further enhance these benefits.
