Coordinated Educational Program for Nutrient Management in Minnesota

Purpose of the Study

The study evaluated the effectiveness and impact of two flagship agricultural events held in early 2026: the 18th Annual Nutrient Management Conference and the 12th Annual Nitrogen Conference. Organized by the University of Minnesota Extension and the Minnesota Agricultural Water Resources Center (MAWRC), these events aim to bridge the gap between academic research and field application.

The primary goals were:

1. Increase the knowledge of farmers and agricultural professionals on profitable nutrient management and relevant environmental issues.
2. Raise awareness among regulators regarding emerging technologies and practices that protect water quality.
3. Provide an open forum for stakeholders to discuss nutrient management perspectives and encourage knowledge-based practice changes.

Key Findings & Survey Results

• Attendance and Reach: The hybrid (in-person and Zoom) format reached 360 total attendees across both events. Based on participant surveys, these conferences directly influence over 7.4 million acres and indirectly influence over 21.1 million acres, impacting a vast majority of Minnesota’s 28+ million agricultural acres.
• Economic & Environmental Value: Averaged across both conferences, 83% of participants reported that the information learned will provide a moderate to great deal of direct economic benefit. Additionally, 86% indicated it would help them make better decisions to safeguard the environment.
• Research Support: An overwhelming 95% of attendees agreed that research funding from fertilizer tonnage fees (AFREC), commodity groups, and local government is essential to generating actionable farm data.

Achievement of Goals and Objectives

The study confirmed that all project objectives were met successfully:

• Knowledge & Engagement: Attendees across both events—composed primarily of farmers, ag industry professionals, and crop consultants—rated presentation quality and content clarity very high.
• Platform & Forum: The hybrid model effectively accommodated flexible attendance, with overall audience satisfaction remaining high and a strong majority expressing intent to return or recommend the program to peers.
• Behavioral Intent: Post-conference evaluations reflected notable increases in attendee confidence regarding key practices such as managing nitrogen in response to tile drainage and utilizing soil/nutrient management tools.

Practical Implementation for Farmers

Farmers can apply key insights and research findings from the 2026 conference programs directly to their operations:

• Optimize Fertilizer Rates: Use decision-support tools like the Maximum Return to Nitrogen (MRTN) calculator and Pre-Sidedress Nitrate Tests (PSNT) to adjust application rates based on actual field needs rather than blanket estimates.
• Drainage-Specific Application: Tailor nitrogen application timing and placement to specific soil drainage conditions to limit nitrate leaching into surface and groundwater.
• Evaluate Biologicals Critically: Utilize real-world field trial data shared during presentations to make cautious, cost-effective decisions regarding biological additives and nitrogen stabilizers.
• Lower Carbon Intensity (CI) Scores: Implement recommended tillage, cover crop, and soil organic matter management practices to lower field CI scores and improve soil health.
• Utilize Manure Effectively: Integrate liquid manure and separated dairy manure into crop rotations (e.g., corn, sugar beets) to offset commercial fertilizer costs while monitoring phosphorus buildup.
