The following article by Kate Malongowski was published by The Lima News, and discusses a statewide study to on farm runoff:
Several Ohio farming organizations, including the Ohio Soybean Council and the Ohio Corn and Wheat Growers Association, are joining together to conduct a long-term study on farm runoff and phosphorus levels.
While phosphorus is needed to help crops grow, the nutrient can become a problem when runoff ends up in bodies of water, causing issues like harmful algae blooms. Grand Lake St. Marys may come to mind.
Many Ohio farming organizations are participating in a $2 million study over three years statewide to determine how much phosphorus runoff comes from farms and how to best solve the issue. Researchers with the U.S. Department of Agriculture and The Ohio State University will analyze the findings.
