High tunnel rises at Dilmun Hill Student Farm

A production-scale high tunnel is rising at Dilmun Hill Student Farm. Once complete, it will not only extend the growing season for the farm, but also serve as an educational resource for the many classes that visit the farm.  A high tunnel production workshop series is being planned in partnership with Cornell Cooperative Extension that will draw on the knowledge and experience of faculty, graduate students, and undergraduates across many different departments.

Cornell University Agricultural Experiment Station (CUAES) staff, along with members of the Dilmun Hill Steering Committee, have been laying the groundwork at the high tunnel site since early spring, grading the land, spreading and incorporating compost, and installing the foundation. This past Wednesday afternoon, they made short work of installing the frame. (See time-lapse video.)

The high tunnel was made possible by the Toward Sustainability Foundation grant program. Undergraduate Steering Committee member and former Dilmun Hill Farm Manager Alena Hutchinson (Mechanical & Aerospace Engineering, ’18) secured funding for the tunnel, and worked with builder Howard Hoover of Penn Yan, N.Y., to design a custom tunnel to meet the specialized needs of small- and medium-sized growers in Upstate New York.

The tunnel will feature a solar-powered, automated sidewall system designed by Hutchinson and fellow undergraduate engineering students to make ventilating the structure easier.

Another innovative feature of the high tunnel:  It is mounted on rails, so that the tunnel can be easily moved between two different growing areas.  Along with increasing production capacity, this design has environmental benefits, such as making crop rotation possible and allowing rain to leach salt from soil, avoiding the salt build up that can be a problem with stationary high tunnels.

Detailed design plans and assembly manuals for all aspects of the tunnel will be available upon the tunnel’s completion. For questions and/or if you want to be involved in the project, contact Alena Hutchinson (amh345@cornell.edu).

Update [2017-07-29]

On June 28, while still under construction, the tunnel took it’s first trip, traveling from a fallow area to an area newly planted with tomatoes, peppers and eggplant.
