As Iowa’s harvest season begins, farmers are reminded to prepare for fall manure application with careful planning and updated certifications.
Dan Andersen, an associate professor and extension agriculture engineering specialist at Iowa State University, emphasizes that proper preparation allows manure to be used as a valuable nutrient resource while protecting soil and water.
The Iowa State University Extension and Outreach agricultural engineering team has released its annual guide to fall manure application. This guide highlights key steps such as manure testing, equipment calibration, and selecting the best timing and soil conditions.
These practices help improve nutrient efficiency, support soil health, and safeguard local water supplies.
Both experienced applicators and those new to manure management are encouraged to review these recommendations to stay efficient and environmentally responsible.
Following the guide ensures that nutrients are applied evenly and at the right time, helping crops benefit from the manure while reducing runoff risks.
Before beginning field work, applicators must also confirm that their Manure Applicator Certification is current. Iowa law requires certification for commercial and confinement site manure applicators.
Farmers have three convenient options for 2025 certification: visiting their county extension office to view a training video, completing online training and payment through the Iowa Department of Natural Resources, or scheduling a testing appointment at the nearest DNR field office.
Completing certification early prevents delays once application begins and keeps farmers in compliance with state regulations.
By preparing ahead, Iowa farmers can use manure as a nutrient-rich resource, improve soil structure, and protect waterways, ensuring a sustainable and productive fall season.
