Land-grant universities work with the people they serve. NU's Institute of Agriculture and Natural Resources does so in priority areas of food, agriculture, agribusiness, natural resources, people and commnities. We teach, discover new knowledge through research, and extend that new, unbiased information across the state and beyond through extension.
