Switchgrass (3 of 3) (IMAGE)
Caption
A bale of switchgrass is weighed after harvesting. The dry weight of the harvested switchgrass allowed Argonne researchers and collaborators to measure the yield of a mixture compared to yields of single varieties grown in isolation. The mixture sustained the highest overall yields over the course of the seven-year study.
