US (NE): Geothermal heat powers Nebraska citrus crop

Members of the Nebraska Master Gardener Program anxiously wait as Alliance’s Russ Finch cuts an orange. While the excitement for a simple orange seems strange, this orange is different. It is a 3-year-old orange that Finch grew in his own backyard.

Finch was simply a mail carrier and farmer in Alliance, until 45 years ago when he started experimenting with heating houses with geothermal heat. Fifteen years later, he began using the geothermal heat to improve greenhouses.

Geothermal heat produces heat from the ground. A singular heat source dispenses heat into a tubing system that runs under the ground of the greenhouse. The heat is constantly circulating and reused to create the perfect environment for the greenhouse. This means that in Finch’s greenhouses, he can grow any tropical or subtropical plant that he wants.

His personal greenhouse is filled with numerous plants, nine varieties of southern grapes, pomegranates, 13 types of citrus fruit and much more. His citrus fruits include Eureka lemons, Meyer’s lemons, Cara Cara oranges, Tango mandarins and Washington naval oranges.
