Cover Crop Mixture Diversity and Function November 30, 2016

Do cover crop mixtures perform better than monoculture plantings? This overview looks at a research study using various plantings of 18 cover crop species, both in monoculture and combination plantings, to examine biomass production as well as the effect of the different plantings on weed suppression, soil nutrient retention, or soil microbial biomass.
