Cover crops play a critical role in nutrient cycling, soil health, and long-term system sustainability. In this CCA Spotlight, Dr. Giovani Preza Fontes shares insights from his research on how cover crops interact with nitrogen management across Illinois and Upper Midwest cropping systems—and what that means for improving both productivity and environmental outcomes.

 

About Dr. Giovani Preza Fontes
Dr. Giovani Preza Fontes grew up in Mato Grosso, Brazil, where he earned his B.S. in Agronomy. He continued his academic training in agronomy and crop sciences at Kansas State University and the University of Illinois, focusing primarily on cover crops and nitrogen fertilizer management across diverse cropping systems.

 

Dr. Preza Fontes’ research and outreach are centered on improving the sustainability of cropping systems in Illinois and the Upper Midwest. Through field-applied research and empirical data, he delivers practical, research-based guidance to help growers balance productivity, profitability, and environmental stewardship. His work identifies best management practices that increase nutrient use efficiency and grain yield while reducing the environmental footprint of modern food production systems.
