Jerry Clark, a regional crops and soils educator with the University of Wisconsin-Madison Division of Extension, has been named the 2025 Wisconsin Certified Crop Adviser (CCA) of the Year, honoring his long-standing dedication to delivering reliable, research-based agronomic support to farmers.
With decades of experience, Clark is widely regarded as a trusted and practical adviser who helps producers balance economic viability with environmental responsibility.
Serving farmers in Chippewa, Dunn, and Eau Claire Counties while influencing practices across the state Clark’s work spans crop management, nutrient efficiency, conservation strategies, and farm profitability.
Clark joined UW-Madison Extension in 1998 after operating a dairy farm in Chippewa County and earned his CCA credential in 2002. Clark holds both bachelor’s and master’s degrees in Agricultural Education from the University of Wisconsin-River Falls and is known for his approachable, farmer-first mindset.
A hallmark of Clark’s career is his commitment to applied on-farm research. By partnering directly with producers, he brings university science into real-world conditions.
Clark’s nitrogen management studies, including participation in the Nitrogen Optimization Pilot Program (NOPP), have helped farmers safely lower nitrogen application rates without yield loss, improving margins while reducing environmental risk.
Clark is also a leading resource on alternative and emerging crops such as malting barley, winter barley, hemp, sorghum, and fruit crops. Through local trials, field days, and economic analysis, he provides unbiased insights that help farmers make informed decisions.
“Jerry Clark exemplifies the mission of the Certified Crop Adviser program,” said George Polzin, a local dairy farmer. “His applied research, accessibility, and deep understanding of local soils and farming systems make him an invaluable resource to Wisconsin farmers.”
