The maize grew on a more-than-usual carbon dense medium. It's interesting that it increased its carbon content, but perhaps not surprising. Nice to see it measured and proven.
Of course. There is nothing about biogas or biofuels that's more efficient. We've known this for at least 15 years and nothing in the space has changed.

Well, one thing changed: Peat is an ancient carbon sink, so draining the peat bog and using it as fertilizer is a great way to increase carbon yields.
If only we could somehow feed coal to corn..
In all seriousness though, as you point out, even in the best of cases, biofuel from corn is more carbon intensive than gasoline.
Supposedly, some processes (such as ethanol 85 from sugar cane) make environmental sense.
