13-Year Record Indicates Differences in the Duration and Depth of Soil Carbon Accrual among Potential Bioenergy Crops
(University of Illinois at Urbana-Champaign/Phys.Org) While annual cropping systems such as maize/soy rotation perpetuate soil organic carbon (SOC) loss, perennial crops have been found to contribute to SOC increases. However, most perennial crop studies have been short-term, resulting in incomplete understanding
