Testing Results from across North America…observed and reported.
1. Seeding deeper than recommended by
experienced agronomists….does produce better results…with the Deere
1890……and always with No-till
deeper and locate the seed in the No-till Buffered Zone.
The Buffered Zone has a more uniform distribution of moisture….allowing
3. The Buffered Zone will germinate more
evenly in air dry soil when the moisture comes in Fall or when the seed is
4. When Roundup is pre-plant applied just
before seeding the crop seems to produce better stands when the seed is
placed in the Buffered Zone. If
5. The university recommendation for
seeding depth is general and for all drills….Even though the university
recommended depth may be length of the
6. The results with the Deere 1890 indicate
the slot does not seal over or crust because of the No-till soil structure
and residue ….
7. The observation of seeding depth is for
Winter Wheat and Spring Wheat. The results of years of testing indicates
many producers are seeding too
8. Do not harrow or pack after seeding
wheat with the 1890. Leave the opener’s tillage effect fully
exposed…valley’s and ridges must remain to assure
9. UNLCE, Paul Jasa reports that Corn
emergence….in no-till the stand establishment results are better when the
seed of hybrid corn is placed at 2.5 to 3
“Seeding Depth is Most
Important.” Eric Odberg.
10. Another major discovery in corn planting
that applies to wheat seeding…..seeding
depth is more important than in the row spacing or the
goal is to establish the stand at the same time….no stragglers…no late
emergence….no seed rotting in a dry
zone…..no seed resting in
12. Plot the solution…if it is dry
conditions or moist conditions seed well below the surface residue. Find
“the Buffered Zone” for the seed to
"Do it No-till and Do it with the
Opener", Paul Jasa.
Cleaners are not necessary with the 1890….not required….if
adequate down pressure is generated….and the wheat seed is placed at 2.25
14. The 1890 opener does not leave the
ground smooth….and this is the opener’s secret….the emergence of the spike
coleoptiles is actually in a
15. When seeding in the Buffered Zone….High
quality Foundation, Registered or Certified Seed must be used. Seed
treatments are always used. High
16. Buffered Seeding with Exactrix Wing
Injection….Seed rate needs to be adjusted lower since the stand will be
much better and could be too
What is the Buffered Zone?
The Buffered Zone is about 2 to 3 inches in depth below the soil surface in No-till. The best place to find the Buffered Zone is in No-till soils.
The organic ooze of life is most concentrated right at the soil surface to about 1.5 inch depth. This aerobic zone of high organic activity is loaded with atmospheric oxygen and thus more acidic. Oxidation means acidic conditions. Thus fungus colonies are highly active in the Aerobic Zone of about 1.5 inches.
The uniformly distributed residue load at the surface will also help to stabilize the soil temperature when night time temperatures drop. The Buffered Zone has a more stable soil temperature.
The Buffered Zone is not ideal for weed seed germination. Weed seeds respond to infrared light and will germinate primarily in the shallow aerobic zone of the surface residue to 2 inches in depth(wild oats excluded).
Soil active chemicals are located at the soil surface in concentrated form to help control weeds…deeper seeding at 2.5 inch are located in a less concentrated area of soil active chemicals.
The Buffered Zone has more crop available nutrients and moisture when
nutrients are banded with Exactrix Wing Injection.
The nutrient bands of TAPPS are located about .75 inches to the side of each 1890 seed row. This seeding and banding technique allows the fine hair roots of the first seminal roots to access the nutrients….no seminal root cap burning is the result….and nutrient uptake at emergence results in plant vigor.
The fine hair roots find the nutrient bands that are highly crop available balanced nutrients ……thus the first leaf is a deep dark green….and fine hair roots penetrate and colonize within the TAPPS band. Normally fertilizer rates are reduced in half due to the geometry and the TAPPS formulation efficiency.
Row Cleaners are not required.
Try to avoid the thought of dragging around another 8,000 pounds of rolling residue removers.
There is virtually no place to stack the residue anyway plus slope angles can really complicate the residue removing process.
Keep it simple and keep the residue exactly where is was relocated by the combine.
The 1890 opener allows the operator to determine how much residue needs to
moved with the opener.
