Methane yield through anaerobic digestion for various maize varieties in China
Abstract
The methane potential of nine varieties of fresh maize harvested at three different times and of maize silage was experimentally determined in batch assays. The ultimate methane productivity in terms of volatile solids (VS) was determined as 213.94-313.63, 195.88-334.81 mL/g VS from several fresh and silage maize in three stages, respectively. The average specific methane yield of wax ripeness stage for fresh maize and full ripeness stage for silage maize were higher than that of other stages, respectively. The high-oil varieties of fresh maize and silage varieties of ensiling maize could produce more methane than general varieties in the same ripeness stage. Methane yield of ensiled materials was higher than fresh material. The methane yields of fresh and silage maize in full ripeness stage were ranged 5656-7956 and 4633-8915 m(3)/ha, respectively. The corresponding maximum of methane yield came from fresh HO5580 and silage CAU No. 4.

An enhancing effect of silage fermentation on methane yields based on ODM added to the anaerobic digestion process as compared with methane yields of biomass prior to ensiling is in accordance with findings in literature.
“An enhancing effect of silage fermentation on methane yields based on ODM added to the anaerobic digestion process as compared with methane yields of biomass prior to ensiling is in accordance with findings in literature (e.g.Gao et al., 2012;Herrmann et al., 2014;Kafle and Kim, 2013) and was discussed in detail previously (Herrmann et al., 2011).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
