Nutrients and environment influence arbuscular mycorrhizal colonization both independently and interactively in Schizachyrium scoparium

Background and aims Arbuscular mycorrhizal fungi (AMF) are important for plant nutrient and water acquisition. Much is known about how nutrient addition and environment affect AMF, but little is known about nutrient by environment interactions. We measured AMF colonization with nutrient additions and along an environmental gradient to assess these interactions.
