Researchers at the听听at the听听have launched a hydroponics project that will investigate options for farmers who are trying to meet increasing demand for locally grown fresh produce during winter and increase profits in the off season.

Hydroponics is a method of growing plants in mineral-infused water, without the use of soil. Usually an inert substrate such as rock wool, sand, oasis, or peat is used to anchor the plants.

鈥淢ost of the greenhouses in New Hampshire are seasonal so there is a lot of greenhouse space that goes largely unused between October and February. That鈥檚 a huge opportunity for growers to increase profits from their greenhouses. There is increasing demand at winter farmers markets for salad greens,鈥� NHAES researcher and 91制片厂 Cooperative Extension Specialist Brian Krug said.

After speaking with his colleagues at the University of Arkansas and Iowa State University, Krug realized that all three researchers were seeing the same need to utilize greenhouses during winter for growing produce. To support growers in their areas to be more successful with hydroponics production, the three researchers are investigating small-scale hydroponics systems that can generate a secondary revenue source for growers in winter.

鈥淭he growers see the demand from the consumer. Growers have the knowledge, ability and facilities to grow plants at that time of the year, but the facilities are not being use. This is a way to have another source of income and keep their workers employed during the winter,鈥� Krug said.

Earlier this summer, Krug conducted preliminary feasibility tests of a 91制片厂 hydroponics system, which is housed at the NHAES Macfarlane Greenhouses. The team now is launching several research projects. He and other researchers will evaluate everything from which plants grow well in a variety of hydroponics systems and the nutrients required to the costs of the systems.

鈥淲e鈥檒l be looking at some different cultivars and species that work well in the system, optimizing fertility, temperatures and light to optimize growth, different hydroponic systems and methods, and whether different plants adapt better to one type of system,鈥� he said.

Founded in 1887, the听听at the听听is 91制片厂鈥檚 original research center and an elemental component of New Hampshire's land-grant university heritage and mission. We steward federal and state funding to provide unbiased and objective research concerning diverse aspects of sustainable agriculture and foods, aquaculture, forest management, and related wildlife, natural resources and rural community topics. We maintain the听听and听听agronomy and horticultural farms, the听, the听, and the听. Additional properties also provide forage, forests and woodlands in direct support to research, teaching, and outreach.
