Spring tillage
Options
With November 1985 being the
wettest on record, many farmers
were caught short with fall tillage,
and even harvesting, incomplete.
As a result, a question most fre-
quently asked is, "What are my
tillage options now?"
Those in the no fall tillage
bracket shouldn't be too upset.
The majority of the fields were too
wet for tillage or any type of work.
In a situation where fields are wet,
patience is best. Yield decrease due
to soil compaction can be far more
damaging than delaying your
tillage program.
Various tillage options are
availabe, from the moldboard
plow to the cultivator, depending
on the crop and soil suitability.
As a standard, most implements
are compared to the fall
moldboard plow. According to T.
Vyn, where corn follows corn, spr-
ing tillage consistently yielded 2-14
per cent less when compared to the
fall moldboard plow. On fields in
rotation the reduction in yield
would not be as great.
The moldboard plow can be a
good spring tillage tool on clay
loam soils. Tillage depth is an im-
portant consideration and you
should observe a 4" maximum
depth. Deep plowing will not in-
crease yields and may in fact
decrease them by diluting your
productive topsoil. Incorporation
of the surface residue is important.
The major disadvantage of this
system is the possibilities of a
droughty or cloddy seedbed. If the
soil is too wet when worked, it
may smear and clod, making
seedbed preparation more dif-
ficult. Research has shown that
secondary tillage is not necessary if
spring plowing is done at the op-
timal time. A yield reduction of 4-5
per cent can be expected on clay
loams when comparing spring and
fall plowing.
The offset or tandem disc may
also be considered for spring
tillage. Its chopping and incor-
porating action can provide an ex-
cellent option in corn or other
heavy residue situations. Disad-
vantages of this implement can be
summed up in one word — "Com-
paction." The disc offers an ex-
cellent alternative for fields that
are well drained. However, soils
which remain wet should be avoid-
