Combining Eddy Covariance Towers, Field Measurements, and the MEMS 2 Ecosystem Model Improves Confidence in the Climate Impacts of Bioenergy With Carbon Capture and Storage

Grant Falvo, Yao Zhang, Michael Abraha, Samantha L. Mosier et autres

ABSTRACT Carbon dioxide removal technologies such as bioenergy with carbon capture and storage (BECCS) are required if the effects of climate change are to be reversed over the next century. However, BECCS demands extensive land use change that may create positive or …

Long-term variability of root production in bioenergy crops from ingrowth core measurements

Cheyenne Lei, Michael Abraha, Jiquan Chen, Yahn‐Jauh Su

Abstract Aims Long-term determination of root biomass production upon land-use conversion to biofuel crops is rare. To assess land-use legacy influences on belowground biomass accumulation, we converted 22-year-old Conservation Reserve Program (CRP) grasslands and 50+-year-old agricultural (AGR) lands to corn (C), switchgrass …

Evapotranspiration of annual and perennial biofuel crops in a variable climate

Michael Abraha, Jiquan Chen, Housen Chu, Terenzio Zenone et autres

Abstract Eddy covariance measurements were made in seven fields in the Midwest USA over 4 years (including the 2012 drought year) to estimate evapotranspiration ( ET ) of newly established rain‐fed cellulosic and grain biofuel crops. Four of the converted fields had …
