Video: Bumper Crops: Cover Crops and Nutrient ManagementDan and Chelsea have a lot to talk about when it comes to cover crops and soil fertility. "So the plant available nutrients in the soil we can think about as being in the soil savings account. And there's only so many of them. We add to that account via fertilizer applications, crop residue breakdown, that type of thing. We remove from that savings account when we plant and harvest a crop. So with a cover crop we're not harvesting that crop necessarily, but we are allowing that cover crop to decompose on the soil surface. So we eventually get those nutrients back."
