Areas of Expertise:

  • Crop Science
  • Agronomy
  • Cover Crops
  • Conservation Management
  • Nutrient Use Efficiency

Assistant Professor & Field Crops Extension Agronomist
University of Illinois Urbana-Champaign (UIUC)

Following his bachelor’s degree at Federal University of Mato Grosso (Brazil), Dr. Preza Fontes earned a master’s degree in agronomy from Kansas State University and a doctorate in crop sciences from UIUC. He spent just over a year in Purdue University’s Department of Agronomy where he helped coordinate statewide research with the goal of improving corn nitrogen fertilizer management in cover crop systems.

Now Dr. Preza Fontes leads the UIUC Field Crops Extension & Research Program where he focuses research on enhancing the agronomic and environmental performance of field crops in Illinois. This involves evaluating and refining multiple management practices with the goal of increasing grain yield and nutrient use efficiency while reducing environmental outcomes like nitrate leaching and greenhouse gas emissions. His role also includes teaching and extension outreach responsibilities.

Fun Facts!
Dr. Preza Fontes enjoys spending time with family outdoors. They enjoy a wide range of activities from playing soccer and grilling to hiking and camping – you may even hear him strumming his guitar! He’s a Kansas fan – K-State football, KC Royals and KC Chiefs. Some of his favorite foods include Brazilian barbeque (churrasco), feijoada (black beans and meat), chicken tetrazzini and anything with chocolate!

Research Projects

Adaptive Management for Maximizing Soybean Production Following Cereal Rye Termination2023-12-20T16:29:04-06:00

Trials in this multi-year project will help researchers better understand 1) how cereal rye influences nitrogen (N) and sulfur (S) availability and soybean uptake, and 2) evaluate soybean yield response to N and S fertilization, alone and in combination, after a cereal rye cover crop.

Integrated Management Strategies for Maximizing Soybean Production in Conservation Tillage Systems2023-12-20T16:25:23-06:00

To help more farmers feel confident implementing conservation tillage systems, this project intends to gain insights into the interactions across soil types, starter fertilizer, tillage systems and row spacings and how they affect soybean growth, nutrient uptake, and seed yield and quality. The results of this multi-year project will enable more farmers to optimize soybean production under conservation tillage systems while preserving water and soil resources.
