Improving Lives Through Innovation and Partnership

As the university's original research organization, the New Hampshire Agricultural Experiment Station is a world-class research facility that has remained an elemental component of New Hampshire's land-grant university heritage and mission since 1887. We steward federal and state funding to provide unbiased and objective research on diverse aspects of sustainable agriculture and foods, horticulture, forest management and related wildlife, the environment, natural resources, and quality of life topics. Our scientists manage more than 50 research projects at any one time, partner with state and regional farmers, growers, and producers, and collaborate with leading researchers worldwide to directly benefit New Hampshire and New England.
