Rills are small signs of erosion due to concentrated flow in the fields. These rills can become gullies so deep that farm equipment cannot easily cross them anymore. Reports have come in about concentrated flow leading to rills and gully formation over the winter. Before widespread adoption of no-till, one would smooth the field every year, which covered up the problem without addressing the cause. Now, we want to be smarter by both repairing erosion damage and armoring the soil so it doesn’t happen again.
