On-Farm Research Corner

Do Soil Health Practices Let You Lower Nitrogen Rates?
Soil health practices like diversified rotations, cover crops and incorporating grazing livestock are known to improve soil health and nutrient cycling. But can long-term investments by farmers in these practices translate to better yields, lower fertilizer costs or both? To find out, 19 corn farmers put this concept to the test in 2023 as part of a multiyear PFI project. The farmers collectively performed 22 replicated strip trials testing their typical nitrogen rate against that rate reduced by 12%-50%. Using an average fertilizer cost of 86 cents per pound of nitrogen, and an average corn price of $5.02 per bushel, 16 of the 22 fields farms saved money using the reduced nitrogen rate. Sean Dengler, who farms near Traer in Tama County, Iowa, was one of those who saw no change in corn yield and better financial returns from using the reduced rate. “I thought my nitrogen rates were high to start off,” Sean said when reflecting on his results. “This trial gives me confidence in reducing them across the board.”
Kevin Veenstra
Kevin Veenstra's trial field on June 19, 2023. He saw no difference in corn yield and reaped financial savings by reducing his nitrogen rate by 20 pounds of nitrogen per acre. Kevin has been using cover crops and no-till on his farm near Grinnell, Iowa, for over seven years.
Join the Research
Wondering if your nitrogen rates are right for you? We're looking for corn farmers in Illinois, Iowa, Minnesota, Missouri, Nebraska and Wisconsin to join this ongoing project for 2025. Eligible fields will have at least a five-year history of soil health practices (cover crops, diverse rotation, integrated grazing, reduced tillage, etc.). The trial involves eight treatment strips. Four strips will receive your typical fertilizer rate, and four strips will receive a reduced rate of your choosing. Joining PFI's on-farm trial is a low-risk way to see if you can maintain corn yields, save money – or both – when reducing applied nitrogen fertilizer.
