Quick Tips - Continued
Setting the Seed Depth
Seed depth is measured from the packed soil surface to
the seed. Set the seed depth on the drill by setting a few
openers across the drill to different depths and seeding
a test patch. Always seed the test patch at the same
ground speed and opener pressure that you intend to
maintain during regular seeding conditions. Then check
the seed depth of these openers, pick the depth setting
that you prefer, and set all openers to the desired letter
setting on the depth adjustment cam. The openers
perform best while seeding from 1/2” (13mm) to 1-1/2”
(38 mm) seed depth, but each customer is responsible
for choosing their own depth setting according to their
preferences and experience. Each adjustment notch
on the adjustment cam is 1/4” (6.4 mm) adjustment.
Shallow depth settings can be consistently maintained
with the Contour Air Drill system.
Note: Be sure to check tractor and/or air cart tracks
to see if the added soil compaction has
affected the seed depth; the independent
openers can be adjusted separately to
compensate for wheel tracks.
Seeding Conditions
The Contour Air Drill is meant to be used as a minimum
to no-till seeding system and care should be taken
when attempting to seed into loose or pre-worked soil
conditions. Shallow seeding depth, reducing operating
speed and operating pressure may help reduce soil
throw and ridging in soft conditions.
Note: Soil throw onto adjacent seed rows also
occurs on conventional air drills with gang
style packers, but is less visible because the
gang packers pack all rows simultaneously
at the back of the drill.
Straw Management
Successful seeding starts at harvest. The height of the
straw should not exceed the row spacing of the seeding
unit. The combine should chop the straw and spread the
straw and chaff evenly across the entire swath width. A
heavy harrow may also be required to spread and break
down the straw after the field has been harvested. If
the straw height does exceed the row spacing a mower
should be used to shorten the straw length.
IMPORTANT
The Paired Row Opener with the NH3 adapter
is intended to allow the operator the flexibility to
switch between granular fertilizer and NH3 without
having to change openers. The opener is not
intended to apply granular fertilizer and NH3 in
the same operation. Excessive gassing off of the
NH3 will occur in such an operation. Producers
are still able to place starter fertilizer with the seed.
Morris Industries shall have no obligation or
liability of any kind on account of the end-user
incorrectly using this opener.
