Whole stalk harvest
Whole stalk harvest will allow a reduction in the cost of transporting the stover without increasing the
cost of transporting the grain. This will be accomplished by better utilization of the available transport
space. By transporting the grain and the stover together we will be able to average the density. For
example, about 42 pounds of corn fit in one cubic foot of space, while only 4 pounds of uncompressed
stover fit in a cubic foot of space.
The whole stalk harvest system solves several other problems as well. The first thing we should see is that
the conventional system is not treating the stover as a valued component of the corn crop. Presently the
stover is left strewn about the ground, driven over by all of the equipment involved in the grain harvest. A
whole stalk harvest could dramatically decrease or even eliminate dirt contamination, eliminate the need
and cost of plastic twine or wrap, improve our ability to target specific parts of the stalk for harvest and
open the stover harvest window, by eliminating stover contact with the ground.
