foot. Between rows,
however, the soil was solid
and difficult to penetrate.
Since the test plot had
received only four inches of
rain from the May 10
planting date through
August 15, researchers
credited the innovative
tillage method with
maximum retention of the
scarce Summer moisture.

Conservationists estimate
that the equivalent of six
indies of topsoil on four
million acres is lost an
nually. Stressing the wise
use of this precious resource,
the plot supervisors set up
side-by-side areas com

chisel plowing, disking and

One comparative test
section depicted corn
growing results from
planting the seed at two
depths; one plot was planted
at one and one-half inch
depth, while the other was
put down three inches in the
soil. The shallower planting
was noticeably taller.

ranging from 12 feet tail to knee high, some with

some with all leaves but no ears.
Specialists overseeing the

Those dates should be

are advised to then schedule

weeks ahead of that
average. Another recom
mendation was to insert
thermometers at different

Researchers see the main
advantage of early planted
com as hitting the most
advantageous pollination
period. According to tests,
the longest day of the year is
the most successful time for

Summer weather usually
becomes too hot and dry for
the best results, as well as
being a time of more con
centrated insect in
