This webinar will provide examples to equip the CCA to evaluate N and P management systems using water quality vulnerability assessment tools for site-specific nutrient planning; evaluate the effect of changing management strategies on risk assessment outcomes and potential N and P loss; compare soil, topography, geography and watershed characteristics on potential environmental N and P impacts; discuss the role of N and P, and past and present management practices on eutrophication; and discuss the role of N in drinking water standards.

Dr. Bruulsema will outline and describe assessment tools for water quality risks in the eastern part of the six-state region. He will review phosphorus issues in the western Lake Erie watershed, and the 4R Nutrient Stewardship certification program developed in response. Integration of metrics representing environmental, economic and social impacts into industry sustainability initiatives will also be covered.

Dr. Jordahl will address several environmental risk analysis issues, including tools states use to assess potential downstream impacts of nutrients, drinking water standards, the Gulf Hypoxia issue, the limits of the 4Rs concept on downstream nutrient impacts, and TMDLs as a regulatory approach that can be used in watersheds.

Speaker Bios:
Dr. Bruulsema is Phosphorus Program Director with the International Plant Nutrition Institute (IPNI). He has played key roles in the development of the 4R Nutrient Stewardship concept, including the co-editing of the IPNI 4R Plant Nutrition Manual. Based in Guelph, Ontario, Canada, he has led research and education programs for the Institute in Eastern Canada and the Northeastern USA since 1995. Dr. Bruulsema has been recognized as a Fellow of the American Society of Agronomy, the Soil Science Society of America, and the Canadian Society of Agronomy.

Dr. Jordahl is the program manager for the Iowa Agriculture Water Alliance, an organization founded by the Iowa Corn Growers Association, the Iowa Soybean Association, and the Iowa Pork Producers Association, focused on accelerating the pace and scale of farmer-led efforts to improve water quality in Iowa, and more specifically implementation of the Iowa Nutrient Reduction Strategy.  Prior to joining the Alliance, Jim worked for 18 years as a soil scientist/environmental scientist in the private sector supporting a broad range of soil and water quality projects across the globe.  Jim has been a CPSS since 1997.
