Jochum Wiersma

Jochum Wiersma serves as an Extension Professor at the University of Minnesota within the College of Food, Agricultural and Natural Resource Sciences, affiliated with the Northwest Research and Outreach Center (NWROC). His work bridges academic research and practical agricultural extension, focusing on crop science and agronomy for Minnesota's farming community.

Dr. Wiersma's research spans crop science, agronomy, plant breeding, and sustainable agriculture with emphasis on small grains. He investigates critical agronomic parameters including planting date optimization, nitrogen management strategies, and disease resistance mechanisms in wheat, rye, and barley systems. His work addresses real-world challenges such as lodging prevention, Fusarium head blight control, and climate adaptation in Upper Midwest agricultural environments. Through field trials and variety development, he translates scientific findings into actionable practices for grain producers.

Analysis of his recent publications (2022-2025) reveals consistent focus on management-intensity impacts across diverse small grain systems. Key trends include hybrid rye adaptation across US regions, genomic approaches to oat improvement, and dual-purpose (grain/forage) crop optimization. His research demonstrates particular expertise in spring wheat production systems, with significant contributions to variety registration and nitrogen-use efficiency studies across Minnesota and Canadian Prairies.

Dr. Wiersma maintains active engagement with the Northwest Research and Outreach Center (NWROC), where he conducts field-based research and extension activities. His work involves direct collaboration with farmers, commodity groups, and industry partners to address regional agricultural challenges through scientifically rigorous yet practically applicable solutions.
