Finding the Right Mix: Multifunctional Cover Crop Cocktails for Organic Systems
A six-species cover crop cocktail established following barley harvest, photographed on Oct 26, 2012.
From our ongoing research, we have developed four recommendations for managing weeds, insects, nitrogen, and cover crop mixtures in general:
Weeds: Have 1-2 species that provide fast ground-cover in the fall, then add species to achieve other goals
Insects: To support beneficial insects for pollination or biological control, manage mixtures to include flowers
Nitrogen: Combine a well-adapted legume with a low seeding rate of a winterhardy grass or brassica
Overall: Aim for balanced biomass from all species in the mix to benefit from a range of functions
