Fields that were hailed, flooded, wind-blown, or where planting was prevented this season need cover crops for all of these reasons since a growing crop isn’t achieving these purposes now. A key soil health concept is that there should be something green and growing during as much of the year as possible (Figure 1). This is important to protect and feed the soil biology, especially arbuscular mychorrhizae fungi. This also “harvests” sunlight and carbon dioxide when they are available to produce biomass for the soil system.
