Case Studies

Case studies have been selected to focus on agricultural water use, water quality problems, appropriate combinations of practices, and climate change effects in the following geographic areas: Lake Erie/Maumee Basin, Ohio River Watershed, Upper Mississippi River Basin, Missouri River Watershed, Lower Mississippi River Basin, and the Great Lakes Fox/Wolf Watershed. They all focus on corn and soybean farming systems where nutrient discharges are a concern. Most are in areas where there is a need for tile drainage.

Case study teams will exchange expertise on practices such as soil amendments, 4Rs, controlled drainage, woodchip bioreactors and P filters, variable rate technologies, tillage, cover crops, crop rotations, nutrient management and two stage ditches. Discussion will include socio-economic factors, barriers to adoption and methods, tools and watershed models that might be useful estimating the water quality, production and economic benefits of different combinations of BMPs.

A primary purpose for team building at the 2014 Workshop will be to develop expectations and water quality targets for the Spring Symposium when teams will return to present results on what it will take to meet targets and field and watershed scales. Click on the case studies to learn more.
