The Story of Nitrogen

Why do some creatures that live in the soil benefit from more nitrogen while others are harmed? This episode tackles the question of how soil microbes are affected by nitrogen fertilizers and how this in turn changes the way we need to manage our soil. Along the way, we get some help from scientists Bruce Potter, Chelsea Carey, and Sada Egenreither, a few bad wildlife analogies, and Lucille Ball.
