Nitrate Removal in a Saturated Riparian Buffer

Learn more about nitrate removal in a saturated riparian buffer from Dr. Tom Isenhart, a professor in the Department of Natural Resource Ecology and Management at Iowa State University, one of the developers of this emerging conservation technology.

The Nitrogen Cycle

This video is a combined presentation by Mike Castellano, an Iowa State assistant professor of agronomy, and Matt Helmers, an Iowa State agricultural and biosystems engineering professor. Castellano presents information on the soil nitrogen cycle. Helmers discusses drainage and nitrate loss.

Performance of In-field Practices at Reducing Dissolved and Particulate Phosphorus Loss

INRC Spring 2022 Water Quality Research Seminar Series: Focus on Phosphorus
Presenter: Antonio Mallarino
, Professor of Soil Fertility and Nutrient management, Department of Agronomy, Iowa State University, and Nutrient Management Specialist, Iowa State University Extension and Outreach.

The seminar reviews results of research targeted at assessing the impacts of fertilizer and manure phosphorus as well as several soil conservation management practices on particulate (sediment bound) and dissolved phosphorus loss from corn and soybean fields.
