Best results come with multi-species cover crops: using 5-10 different plant species as cover crops simultaneously. This improves the biodiversity of the regenerative agriculture system and provides several important benefits:
● Improved resilience to pests;
● A more balanced and resilient soil ecosystem; and
● Improved resistance to environmental factors, like changes in local weather, drought.
A recent study found that “there are species-specific cover crop effects on soil microbial community composition that ultimately influence soil biological activity.” (Finney, 2017) Multi-species cover crops provide combined benefits from multiple species. Recent research also shows how regular repeated use amplifies the benefits of cover crops. (Housman, 2021).
