Chapter 9 : Cover Crops

Cover crops provide additional protection to the soil both dusing the growing season and outside it, while not interfering with the growth of cash crops (Belfry, 2016). They manage or prevent soil erosion, improve soil fertility and quality (as green manure), and improve water retention and management, and provide pest, weed, and disease resilience. In addition, they improve biodiversity and improve farm habitat for wildlife, and provide additional biomass production (Freemark, 2001; Cederbaum, 2004). A considerable body of research demonstrates links between cover crops and soil biology, as well as the effects of single species and multi-species cover crops (Finney, 2017).
