Dr. Hanson was involved in a broad range of research projects addressing applied questions related to fruit production, with an emphasis on berry crops. Some of Dr. Hanson's interests have included the mineral nutrition and fertilizer use in fruit production, cover crops and weed management, growth regulator use, berry genotype screening for adoption to Michigan conditions, and high tunnel use for berry production.  The primary crops he has worked with are blackberries, blueberries, cranberries, grapes, raspberries and strawberries.


Dr. Hanson provided berry crop producers with current production recommendations through printed and on-line resources, meetings, and field demonstrations. He served as resource person for Extension educational programs in Michigan and elsewhere on topics such as berry crop nutrition, weed management, variety selection, and horticultural practices, provided in-service training for Extension educators, and served as Education Coordinator for the Michigan State Horticulture Society, coordinating fruit education programs for the Great Lakes Fruit, Vegetable and Farm Marketing EXPO.
