The carbon and nitrogen cycle impacts of reverting perennial bioenergy switchgrass to an annual maize crop rotation
In the age of biofuel innovation, bioenergy crop sustainability assessment has determined
how candidate systems alter the carbon (C) and nitrogen (N) cycle. These research efforts
revealed how perennial crops, such as switchgrass, increase belowground soil organic
carbon (SOC) and lose less N than annual crops, like maize. As demand for bioenergy
increases, land managers will need to choose whether to invest in food or fuel cropping
systems. However, little research has focused on the C and N cycle impacts of reverting …
