Des Moines, Iowa — The Iowa Department of Agriculture is trying a new approach called “batch and build” to address runoff that impacts water quality.
Ag Secretary Mike Naig says it involves doing several water quality projects together.
Naig says it brings more people in to get more done.
He says there is more efficiency in the work.
The bioreactors and buffers at the edge of fields help remove nitrates from the water that comes off tile lines.
