Today at noon, Laurie Nowatzke, Measurement Coordinator for the Iowa Nutrient Reduction Strategy at Iowa State University, discussed the progress and challenges of Iowa’s water quality improvement efforts.
The webinar covered how progress towards the Iowa Nutrient Reduction Strategy (NRS) is measured, how much progress has been made and what challenges remain. The NRS is a science-based strategy to reduce nutrients in surface water from both point and nonpoint sources. Nowatzke shared a brief history of the measurement tracking associated with the NRS and then discussed the recently published 2017-2018 Annual Progress Report.
She explained how the NRS uses a logic model framework to track quantifiable change in inputs, the human dimension, land use and water quality. The 2017-2018 Annual Progress Report shows an increase in funding for conservation practices and programs, mostly due to an increase in Conservation Reserve Program (CRP) rental payments. It also shows an increase in outreach and education events. Farmer attitudes towards and awareness of the conservation efforts is being measured through a five year survey. Summaries of the survey results for two HUC6 watersheds are available in the report.
Nowatzke also described how conservation practices are tracked, including the tracking of CRP land retirement, cover crop use, and the installation of bioreactors and saturated buffers. Water quality progress is assessed using a two-pronged approach of measuring nutrient concentrations in surface waters and modeling nutrient loss reductions that are associated with different conservation practices.

Join us next month, on Wednesday, August 21 at noon, when Jacqueline Comito, Iowa Learning Farms Program Director, will present an Iowa Learning Farms webinar titled “15 Years of Iowa Learning Farms”.
