In episode 80 of the Illinois Nutrient Loss Reduction Podcast, University of Illinois Assistant Professor and Extension agronomist Giovani Preza Fontes shares results from a research project evaluating soybean performance across different tillage systems and fertilizer strategies. The study was initiated following recent dust storm events in Illinois and across the Midwest, including the tragic 2023 event near Springfield.
The conversation centers around one question:
Can conservation practices help reduce soil erosion without sacrificing yield or profitability?
Why this research matters
Fontes explained that this project started in response to recent dust storms and growing concerns about soil erosion. While practices such as no-till and cover crops are known to reduce soil loss, adoption across Illinois remains relatively low. Cover crop adoption is less than 10% on our corn and soybean acres, and about 15% of corn acres and 35% of soybean acres are managed with no-till.
He noted that some of that hesitation stems from the perception that these practices carry additional risk, particularly the risk of yield loss.
At the same time, these practices are a key part of the Illinois Nutrient Loss Reduction Strategy to reduce nutrients leaving agricultural fields. Keeping soil in place helps protect water quality while also supporting soil health and nutrient cycling in the field.
