Other claims from this paper (10)
- Observation Corn grain had the highest potential ethanol yield, averaging over 4100 L per hectare.
- Intervention effect Converting corn grain and stover increased potential ethanol yield.
- Observation Willow had the lowest potential ethanol yield.
- Observation At one site, topsoil under willow had nearly 13 Mg C per hectare, or 29%, more soil organic carbon than under switchgrass or corn.
- Observation Corn soil macroaggregates had lower carbon than those under perennial grasses or trees.
- Observation Corn soil macroaggregates had lower nitrogen than those under perennial grasses or trees.
- Observation Corn soil macroaggregates had lower carbon to nitrogen ratios than those under perennial grasses or trees.
- Observation No-till corn had high ethanol yields with equivalent soil organic carbon stocks to 40 cm depth.
- Recommendation The authors recommend long-term monitoring of soil organic carbon stocks at depth.
- Recommendation The authors recommend ecological, energy and greenhouse gas assessments of each feedstock’s carbon footprint.
