Cover Cropping on the Canadian Prairies: A Mixed Methods Study to Gain Understanding of Cover Crop Agronomic Practices Among Farmers
… found with fertility and residue management, CC stand establishment, and crop rotations. Farmers have built confidence in the benefits of CC through improved water retention, reduced soil erosion, reductions in cash crop inputs, and additional grazing opportunities. A new finding is that farmers …
