Midwestern agriculture contributes the vast majority of nitrogen in the Gulf of Mexico, causing an oxygen-starved hypoxic zone and challenging coastal economies. State and federal policies have tried for decades to provide solutions and incentives, but the hypoxic zone keeps coming back.

Diversified crop rotations protect water quality and have other environmental benefits, but recent experiments show that farms can’t rely on such rotations to improve carbon storage in the soil. The findings contradict widely held expectations that the extensive root systems of perennials and cover crops would deposit carbon in soils.
