COLUMBUS: Ohio officials want more power to stem the spread of toxic algae caused by pollution runoff from farms.

Changes proposed in a Senate bill would give the Department of Natural Resources the authority to cite farmers if rain washes too much fertilizer off their fields.

It also would require farmers to undergo training and receive a certificate from the Ohio Department of Agriculture before they could spread fertilizer.

The Columbus Dispatch reports that the provision would also keep the public from seeing an individual farmerís fertilizer and manure-management plans.

Officials say changes in the law might be necessary to reduce toxic blue-green algae in Lake Erie, Grand Lake St. Marys and other Ohio lakes every summer, affecting tourism, aquatic life and public safety.
