Federal agriculture officials say they're spending $2 million to help farmers in Ohio, Michigan and Indiana keep phosphorus from entering waterways in the western Lake Erie basin.
The U.S. Agriculture Department says projects include using new tools such as biofilters and controlled drainage. Officials say excessive phosphorus from manure causes blue-green algae to proliferate in rivers and streams, limiting oxygen concentrations in water.
Agriculture Secretary Tom Vilsack plans to announce the effort today in Michigan.
