The development of industrial uses for cornstalks is dependent, in a large measure, upon an adequate supply of raw material at a reasonable cost.
Cornstalks, being light and bulky, are difficult to handle, and economical harvesting is essentially a problem of reducing labor.
The yield of cornstalks (15 percent water content basis) varies from 1 to 2 tons per acre.
Dry, wind-blown stalks in Iowa may be expected to yield from 1/2 to 11/2 tons per acre.
Cornstalks cannot be harvested economically by hand.
