Healthy soil is the heart of our food system and, by every conceivable measure, we are making our soil sick. In Ontario, soil organic matter—a key determinant of soil health—is now decreasing on 82 per cent of farmland. Since 1948, the soil organic matter in Essex County, in the province’s far south, has declined by more than half on the vast majority of farms. Meanwhile, 54 per cent of farmland across Ontario now has high levels of erosion risk.
