Camelina is pulling double duty as a biodiesel source and a cover crop. And this article from the U.S. Department of Agriculture says it is also keeping bees well fed.
[S]cientists with USDA’s Agricultural Research Service (ARS) have found that its flowering period can provide honey bees and other insects with a critical, early-spring source of nectar and pollen that’s usually unavailable then. This is especially true in Minnesota, South Dakota and North Dakota, where about one-third of the nation’s managed bee colonies are kept from May through October.
The researchers observed that fields of winter camelina and winter canola (another alternate oilseed crop) produced about 100 pounds per acre of nectar sugar over the course of a two- to three-week flowering season. That quantity, produced in such a short time, is enough to support the annual energy requirements of a typical bee hive, which is 100-200 pounds of sugar per year, according to Frank Forcella, an agronomist with ARS’ Soil Management Research Unit in Morris, Minnesota. He participated on a team of ARS and university scientists which evaluated the attractiveness of camelina, canola and a third oilseed crop—pennycress—during two years of outdoor field trials.
Highlights of the team’s findings—reported in the June 2015 issue of Industrial Crops and Products—are: Continue reading
