No till necessary to eliminate
declining productivity :Lobb
A Clinton area farmer who has been using
no tillage conservation practices on his farm
since 19Xl sees no -till as a necessity to
eliminate the declining productive potential
of the soil on the steeper slopes on his farm as
well as areas where soil types are not well.
adapted to no -till.
"After all, yields that are sustainable at 90
- 95 per cent of full potential will very shortly
be higher than yields on eroding land under
conventional till," observes Don Lobb.
Why should no -till work for Don Lobb when
frequently reported results from on farm
tillage trials, demonstrations by various
government and Ontario :.research have
tended to produce condescending comments
at best?
In the instances of the farm tillage trial
reports and government demonstrations,
Lobb says the least familiar tillage systems
are disadvantaged because he suspects a
predetermined production formula is used,
without regard for 'the needed adaptation
process for management and Local conditions.
To complicate matters, immediate yield
comparisons are deemed necessary to justify
time and dollars spent. Thus a system such as
no -till is treated as a curiosity rather than a_
possible solution to specific problems.
"The object as I see it," says Lobb;
"should be to determine where and how it
can be fitted to local conditions and individual
management.
The results of Ontario tillage research
produces headlines like, "Fall Plow Offers
Tbp Com Yields", or researchers' comments
like, "Average'No-Till eorn,yields decrease is
12 per cent". Examination of the fads
indicates that' with few exceptions, tillage
research in Ontario has been donein terms of
the continuous corn ethic which was popular a
decade ago.
"W e already know that continuous corn is
neither good for the soil or our bank
accounts," observes Lobb.
Long term Elora tillage trials, which
include no -till vs conventional till justify some
consideration. The predictable yield reduc-
tion associated with continuous corn is
evident. It is interesting to note that recent
no -till yields, in the longest running trial at
this site, are very dose. to those of 'conven-
tional till. The question raised is, are we
seeing, the result of biological adjustment in
the soil or improved equipment?
Research which includes other than very
recent data may have questionable value as a
measure of potential for a tillage system, says
Lobb. Researchers too must be learning as
they use a new system
"I gather as much information as possible,
consider it and then relate it to my situation,
with as 'much objectivity as possible," says
Lobb. "Me same principle applies to fanner
testimonials, magazine articles or whatever."
On the positive side, current University of
Guelph work, which does not include corn
following crops others than corn, has the
potential to produce more practical informa-
tion and more useful tillage recommendations
in terms of today's needs. The work of the
tillage team at the Guelph university has been
limited, Lobb suspects, by the lack of Ontario
commitment to tillage research.
The result is that Lobb must look to the
United States for comprehensive tillage vs
soil type vs crop history comparisons. Lobb
believes the best is a Purdue University
paper. As with Ontario studies, no -till corn
