Iowa Nutrient Strategy Released21 November 2012
US - Following calls to clean up the Mississippi river, academics in Iowa have released a Nutrient Reduction Strategy designed to direct efforts to reduce nutrients in surface water from both point and nonpoint sources in a scientific, reasonable and cost effective manner.
Terry Branstad joined Iowa Secretary of Agriculture Bill Northey and Director Chuck Gipp from the Iowa Department of Natural Resources and John Lawrence from Iowa State University to announce the release of the Iowa Nutrient Reduction Strategy for public comment.
The Iowa Nutrient Reduction Strategy is a science and technology-based approach to assess and reduce nutrients delivered to Iowa waterways and the Gulf of Mexico. The strategy outlines voluntary efforts to reduce nutrients in surface water from both point sources, such as wastewater treatment plants and industrial facilities, and nonpoint sources, including farm fields and urban areas, in a scientific, reasonable and cost effective manner.
The Iowa Department of Agriculture and Land Stewardship and Iowa Department of Natural Resources worked with Iowa State University over a two-year period to develop the strategy.
The Iowa strategy has been developed in response to the 2008 Gulf Hypoxia Action Plan that calls for the 12 states along the Mississippi River to develop strategies to reduce nutrient loading to the Gulf of Mexico. The Iowa strategy follows the recommended framework provided by EPA in 2011.
“The strategy’s science assessment provides a research-based foundation to quantify the effectiveness of current practices for reducing nutrient losses from the landscape,” said John Lawrence, associate of ISU’s College of Agriculture and Life Sciences and director of ISU Agriculture and Natural Resources Extension.
“The assessment reflects two years of work to evaluate and model the effects of the practices by scientists from ISU, IDALS, DNR, USDA Agricultural Research Service, USDA Natural Resources Conservation Service and other institutions.”
Iowans are invited to review the strategy and provide feedback during a 45-day comment period that starts today and will end on January 4 2013. The full report, additional information and place for comments can be found at www.nutrientstrategy.iastate.edu.
Point Sources (DNR)
The Iowa Department of Natural Resources will be working with major facilities throughout the state to reduce nutrient discharges from point sources to Iowa’s waters with a goal of reducing total phosphorus by 16 percent and total nitrogen by 4 per cent.
“The DNR has been working with the Iowa Department of Agriculture and Iowa State for nearly two years and support this strategy document and the collaborative process that created it. Many Iowans enjoy our state’s natural resources and it is important we protect them for future generations,” Gipp said.
To address nutrient transport from nonpoint sources, the strategy uses a comprehensive, first of its kind scientific assessment of conservation practices and associated costs to reduce loading of nutrients to Iowa surface waters. The strategy identifies five key categories to focus the efforts in addressing nonpoint sources and identifies multiple action items within each category.
The five categories are: Setting Priorities; Documenting Progress; Research and Technology; Strengthen Outreach, Education, Collaboration; and Funding.
