Does Riley creek have to turn brown after a rainfall event?

The short answer is no. But why does it turn brown? Most farm field’s drain into lakes and streams in our community. Unfortunately last fall many farm fields were tilled bare, exposing soil to erosion. Often a fall tillage pass is done to break up the soil and reduce compaction caused by heavy machinery.  Heavy machinery will always make some compaction. The last two fall seasons were very dry; as a result I would argue there wasn’t as much compaction made as farmers think. After a tillage pass is made rain water does infiltrate into the soil quickly. Soon after that the topsoil crusts over and water infiltration begins to decline, resulting in the need for another tillage pass. As farmers and landowners it is our responsibility to reduce erosion. The annual rate of soil erosion in Ohio is approximately 2.7 tons. That is not acceptable and it doesn’t have to be this way.
