Webinar: erosion effects on phosphorus levels

     An Iowa Learning Farms webinar on Wednesday, April 20 at noon will cover phosphorus contributions attributed to streambank erosion.

     Keith Schilling, state geologist and director of the Iowa Geological Survey, will direct the webinar. Schilling conducts research on water-related issues in Iowa that include groundwater flow and quality, surface and groundwater interaction, nonpoint source pollution, and watershed and flood plain processes.

     He will discuss a collaborative study in which a variety of methods and a multistep process were employed to help determine the amounts of P originating from streambank erosion in relation to total P levels in waterways.
