Corn stover

[3] In the silage use case, it is usual for the entire plant (grain and stover together) to be chopped into pieces which are then crushed between rollers while harvesting.

[5] In addition to the stalks, leaves, husks, and cobs remaining in the field, kernels of grain may also be left over from harvest.

These left over kernels, along with the corn stover, serve as an additional feed source for grazing cattle.

Over time, the stalks will decrease in value as feed, so farmers aim to graze the corn stover as soon as possible after harvest.

"[8] However, with current technology, a large part of the biofuel potential of cellulose is wasted due to the strength of the glycosidic bonds that pair chains of D-glucose units.

"[8] The free accessibility to corn stover makes it a prime candidate for biomass ethanol production.

DuPont opened a facility in Nevada, Iowa, that was expected to generate 30 million gallons annually of cellulosic biofuel produced from corn stover residues.

Humus, alternatively known as digestate, is a value-added lignin- and nutrient-rich soil amendment similar to peat moss or compost which may be returned to feedstock suppliers or further processed into marketable products.
