Injecting farm fertilizer below the ground instead of spreading it on the surface could help achieve most of Lake Erie’s 40 percent phosphorus reduction goal, said CFAES scientist Margaret Kalcic in a Dec. 3 story in the Toledo Blade. The practice also would allow farmers to maintain their productivity, she said.
The reduction goal is aimed at preventing the harmful algal blooms plaguing the lake. Agricultural phosphorus runoff is considered the blooms’ main cause.
A recent Columbus Dispatch article said there’s reason to be optimistic in the battle against Lake Erie’s algal blooms. Robyn Wilson, who studies risk analysis and decision science as an associate professor in CFAES’s School of Environment and Natural Resources, was one of the experts quoted. “I don’t think we need regulation,” she said in the article. “I think farmers have gotten a bad rap. They are highly motivated to fix the problem under their own terms.” Read the article. (Photo: Lake Erie algal bloom by Tom Archer, Michigan Sea Grant.)
Ohio State scientists are developing ways to identify the many kinds of phosphorus getting into Lake Erie. To do it, they’re determining the compounds’ chemical signatures. The goal is to be able to link the compounds back to their sources — whether farm field, livestock facility, wastewater treatment plant or otherwise — and so better target efforts aimed at keeping phosphorus out of Lake Erie. Excess phosphorus is one of the causes of the harmful algal blooms plaguing Lake Erie and other lakes. CFAES’s Field to Faucet initiative is a co-funder of the research.

Learn the latest on Lake Erie’s blue-green befoulers at Understanding Algal Blooms: State of the Science, a Sept. 15 conference in Toledo. The event, according to its website, will “highlight current scientific knowledge about algal blooms: model predictions, updated best management practices and water treatment methods to remove toxins.” Co-hosts are Chris Winslow, interim director of the Ohio State-based Ohio Sea Grant program, and CFAES’s Jay Martin (head of the Field to Faucet initiative), Greg LaBarge and Kevin King.

CFAES experts recently posted videos of the commercial fertilizer training they’re providing. Completing this training in person is required of anyone who applies fertilizer on more than 50 acres in Ohio. Watching by video can give you an idea of what the training is about if you haven’t taken it yet, can be a refresher if you’ve already taken it, or simply can show you, if you’re interested, some of the research-based, forward-moving steps being taken to keep Ohio’s water clean. You can watch an example above.
Could water quality trading help solve Ohio’s nutrient issues? Farm and Dairy’s Chris Kick has the story, reporting on the recent joint meeting of the Water Quality Taskforce and the Agriculture and Rural Affairs Committee of the County Commissioners Association of Ohio. The meeting was at OARDC in Wooster, which is CFAES’s research arm, and had several speakers from CFAES.
In the new video above, CFAES’s Jay Martin talks about a recent report on the best ways to improve Lake Erie’s water quality while making sure farms stay healthy — that is, that they’re good producers of food, profitable for the farmer and sustainable for the environment. Martin heads CFAES’s Field to Faucet water quality initiative. There’s a previous related post here.
