In an article recently published in Agronomy Journal, researchers used relative Land Equivalent Ratio (LER) to show that mixed-species did not always outyield singlespecies cover crops but were more consistent in total biomass production. Grass and taproot species usually provided greater biomass than legumes, but cover crop consumption left less available nitrate and stored water for a following crop compared with fallow. Relative LER may provide a useful criterion for cover crop mixture construction.
