Antonio Mallarino


Dr. Antonio Mallarino is Professor of Agronomy, Nutrient Management Research and Extension Specialist, at Iowa State University. His research and outreach efforts focus on cost-effective, sustainable, and environmentally sound nutrient management practices for Iowa cropping systems. Emphasis is on fertilizer and manure management, soil and plant tissue testing, use of precision agriculture technologies, and minimizing phosphorus management impacts on water quality. He contributed to the development of the Iowa Phosphorus Index, contributes to the Iowa Nutrient Reduction Strategy science team, and represents Iowa State University at the USDA/NIFA committees North Central Extension and Research (NCERA-13) and Minimizing Phosphorus Losses from Agriculture (SERA-17). He began his professional career at the University of Uruguay and joined the Iowa State University faculty in 1993.

Brian Gelder

Brian Gelder is a central Iowa farm boy who went to college and never left. He accomplished a MS stint in Colorado researching reservoir water quality models and returned to Iowa State for a PhD in erosion modeling, to farm part time with his father, and raise his own family, all while still finding time to bike and canoe.

Breanna Marmur

Bree Marmur is a Ph.D. student in the Department of Natural Resource Ecology and Management where her research focuses on urban stormwater management and green infrastructure. Investigating both the effectiveness of small-scale stormwater best management practices and factors that encourage homeowner engagement in stormwater management, Bree spends her time in the field monitoring and sampling stormwater, out talking with urban homeowners about stormwater management, and at the computer working on hydrologic models. Bree’s background, with an MS in mechanical engineering and a BA in physics, allows her to bring a unique engineering perspective to natural resource management. Bree lives in Ames with her partner, a fellow ISU Ph.D. student, and their dog, Doc.
