This makes it attractive to those wanting a fast growing cover crop that will be incorporated in the late summer. Summer covers make greater contributions to biodiversity because insects, birds and amphibians feed and reproduce during the growing season.

It needs soil temperatures of around 42°F. Dealing with weeds Looking back, if we did not control volunteer plant growth with either tillage or herbicide, we would have had good volunteer ground cover during the summer. The cold-hardy crop will grow in buckwheat’s shade until a killing frost mows down the buckwheat, freeing the other plants for a surge of growth before winter dormancy. Gardeners have two options when planting cover crops. Advantages include: substantial biomass, the ability to fix nitrogen and potential to kill soil-borne diseases and nematodes. Already a Member?

Advantages include: potential to suppress soil-borne disease, high organic input, drought resistance and winter kill. On this farm, allelopathic sorghum-sudangrass is grown in alleyways to suppress weeds and produce fodder for compost, while cowpeas fix nitrogen in the space to be followed by food crops. Although overwintered covers provide those same benefits, summer cover crops yield a wider range of home-produced feeds for poultry and livestock, including cut-and-come-again greens, grains and seeds, and dried cover crops used as hay.
