This second test was conducted with a forage mill:
as obvious, the machine is too small to chop large
quantities of biomass, but was the only one of
that kind available at the time; there are much
bigger ones. What really counts is that the chopping
is performed on the horizontal axis as compared
to the insertion direction of the biomass.
This fact guarantees a much stronger coherence
if compared to the previous test.
The result was much more satisfactory than the
previous one; next year I'll chop a large quantity
of leaves and stems with a much larger mill. also
the timing of the operation will be an interesting
data to account for.
