Senior Extension Associate
Larry Geohring is a Senior Extension Associate in the Department of Biological and Environmental Engineering. His interests include competitive agricultural systems and greater harmony between agriculture and the environment. His program emphasis is water quantity and quality issues in agriculture and the transport and fate of nutrients in the landscape.
My research focuses on environmental impacts of land management practices, and evaluating techniques to reduce the impacts.
Outreach and Extension Focus
Larry’s extension learning activities focus on the environmental impacts of land management practices and evaluation of techniques to reduce their impacts. Activities consist of conducting applied, field-based research with cooperating entities, providing technical information resources and guidance regarding water and soil management practices, and carrying out various educational training activities. Larry’s applied research is performed at Cornell University farms or at other locations selected in cooperation with state and local government to investigate specific concepts or problems. The visibility of the applied research often leads to further requests for technical information, either directly or via referrals, and technical support is provided to county, regional, state, and campus personnel. Educational training is generally coordinated with Soil and Water Conservation Districts, USDA-NRCS, non-profit organizations, or Extension-organized training events and meetings.
Larry currently teaches BEE4270 Water Measurement and Analysis Methods and BEE 4740 Water and Landscape Engineering Applications. These courses include instruction on environmental monitoring and characterization of water and soil resources. He also teaches students how to apply principles of engineering and soil physics to address land improvement and soil and water management practices.
