In Remembrance

David N. Sundberg died unexpectedly in his sleep on 4 May 2014. Dave was born in Storm Lake, IA, and grew up working with his father on their family farm near Linn Grove. He graduated with B.S. and M.S. degrees in agronomy from ISU, and was employed as an Agricultural Specialist in the Department of Agronomy for 32 years. He was a vital member of our research group, leading activities in the field and lab. His attention to detail, careful planning, knowledge of farming practices, and hard work were essential to the successes achieved in projects undertaken by our team. His love of farming and Iowa land was apparent throughout his life. Dave is survived by his wife, Nancy, and two children, Michael and Hanna.
