Webinar: Environmental Impacts of Poorly Drained Agricultural Soil | Building a Culture of Conservation

Webinar: Environmental Impacts of Poorly Drained Agricultural Soil

October 27, 2021

Ames, Iowa – The Iowa Learning Farms conservation webinar taking place Nov. 3 at noon CDT will feature Steven J. Hall, associate professor, department of ecology, evolution and organismal biology at Iowa State University. Hall’s team takes an interdisciplinary approach to understanding soil organic matter dynamics, production of greenhouse gases, and nutrient cycling and water pollution, in agricultural and natural ecosystems in Iowa and across North America.

In the webinar, “Environmental Impacts of Poorly Drained Agricultural Soil,”  Hall will discuss the role soil drainage characteristics play in nutrient loss to water systems and greenhouse gas emissions from agricultural systems. Focusing on poorly drained soils that do not support robust – or sometimes any – crop growth, Hall will highlight ways that land use and nutrient management decisions could reduce the disproportionate share of landscape-scale losses attributable to these underproducing areas.

“Low-lying areas, such as the prairie potholes that are common in Iowa, occasionally flood or simply do not drain well, inhibiting crop growth and therefore reducing the utilization of fertilizer applied to them,” said Hall. “This sets the stage for higher rates of leaching of nutrients into drainage water and emission of nitrous oxide gas into the atmosphere. Such poorly drained soil areas should be targeted for alternative management to improve environmental outcomes.”

Participants in Iowa Learning Farms Conservation Webinars are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
