Iowa Farms Test Camelina as Corn and Soy Cover Crop
Practical Farmers of Iowa issued a research report on on-farm testing of camelina as a cover crop for use with corn and soy rotations. Farmers looking for winter-hardy alternatives to small-grain cover crops tried the brassica camelina as a cover crop. In one of three on-farm tests seeded in Fall 2018, the camelina winterkilled. At the other two sites, soy and corn yields were not affected by the camelina cover crop, compared to no cover crop. One of the farmers participating noted that the camelina’s small seed size allowed lower seeding rates that would lower application costs.
