KS, Why is Winter Canola such a powerful rotation?

You may find the above articles provide a solution to why SRS
works only when the soils are dry (around 12% moisture). SRS
requires that seeded soils will dry out after seeding.
This also explains why the best stands of Corn and Spring Wheat are
never produced by watering up the crop with irrigation.
Saturated soils do not allow the Abscisic Acid to drain away or
to be leached away from the seed.
Wet soils and soils that are cold and not allowing a dry down do not
have the valuable conditions to make SRS work properly. SRS probably
has no value in super saturated wet and cold soil conditions. But Osmo Priming and Hydro Priming may work in these conditions.
Seed Row Saturation, So to consider SRS, the soils must be
low in moisture (sub 44% to 12%) and dry from 2 inches to 3 inches
to the soil surface…very dry from the normal seeding depth and moist
there under the seeding depth whereby the soil stored moisture can
be coupled to the seed row saturation line of moisture. (as deep
as 4 to 5 inches to moisture by raising the flow rate and seeding
deep in hot conditions). Test your soil moisture case in selected
pilot passes and or test plots in various soil types and weed
control scenarios of the Chemfallow.
“The critical word is coupling”….of the two horizons to start the
germination and to leach the Abscisic Acid”…typical measured and
tested results indicates this takes 150 gallons of water per acre on
10 inch row spacing. In row crop 75 gallons per acre on 20 inch
spacing and 50 gallons of water per acre on 30 inch spacing.
The key word is Saturation. “ Do not shortcut the in the row
water”….your system should be designed to go to the top of the
mark based on conditions…and should be tested prior to planting
Winter Canola at 5 different rates….Your soils and capillary
movement can be different from farm to farm…Compaction and tillage
can greatly interfere. No-tillage is absolutely the best way to
establish Winter Canola. The cost of water is about $2.00 per acre
primarily for the hauling.
You might be willing to pay $100 per acre for a 99% stand of winter
canola….and yet you are arguing with yourself about the cost
difference of 40 gallon per acre verse 65 gallons per acre of
water. That is not much money and when your read on you will
discover Saturation to the moisture line is the key.
There should absolutely no splashing of the water flow out the row
or onto the machinery…the goal is to release the water at low
terminal velocity. Dual Tubes can be used in hillside to stop the
Do not make
this mistake. The technique of SRS is not like seed row
fertilizer since the already installed fertilizer equipment is
improperly sized. SRS is sized for about 8 to 10 times more flow
than typical in row fertilizer on a 30 inch planter.
The terminal velocity at 1.5 GPM should be no greater than 5
psi at 1% CV application variance since tricky chemicals can be in
The SRS delivery tubes must have ability to handle about 1.5 gallons
to 1.75 gallons per minute on a planter.
In the Pacific Northwest control of pre-plant germinating weeds is
very important to maintain the moisture line. The SRS technique was
developed around Chemfallow seeding of Dwarf Essex Winter Rape. The
uncontrolled weeds in Chemfallow rob moisture during the hot soil
days(100*F) of July in eastern Washington and Northern Idaho. Weed
control must be superior in the pre-plant preparation of the
Chemfallow program. Do not make a bet on rain to bring the crop up.
The crop must emerge evenly and within 4 to 5 days producing a 99%
stand with a plant every 4 to 5 inches.
Remember the top yields will come with even and uniform stands by
keeping the fertilizer away from the crop. Keep the fertilizer
away until dormancy starts in late fall or late winter. Use your
Mustang TAPPS Single Disc, No-tillage Tool Bar to get the TAPPS
bands into the soil about 7 inches in depth.
For a good start and top yields, the seedling winter canola plants
must come out of the ground together. The loss of a plant leaving an
8 to 10 inch space on 30 inch spacing is not considered significant
for top yields, but a variable emergence over 10 to 20 day period is
All the winter canola plants must come together in a 99% stand in
about 4 to 5 days of planting. This technique is critical for
using chemicals and growth regulators. This is a very critical part
of mystery of top yields in Winter Canola. Another plus is the seed
costs drop from $45 per acre drilled to $8.00 per acre planted using
the highest quality hybrid types of Winter Canola. Hybrid Winter
Canola is the dominant choice due to the resilience required to face
the weather of the Great Plains.
Corn producers know it well. The top yields require an even and
uniform stand and billions of dollars have been spent trying to get
this uniformity and it’s great return. “If winter wheat producers
think there are similarities of winter canola with winter wheat you
have been misinformed.” Winter Canola producers must enter the era
of precision and producers must change your machinery line up to
make the top yields. Kansas producers have a jump start since they
already own planters in the irrigated and dryland areas.
Yes, Winter Canola and Winter Rape can be planted from June 22
onward in hot and dry Chemfallow conditions using SRS. Center pivots
should be pre-irrigated to a soil depth of 2 to 3 feet. Center
pivots will respond very well to SRS with no moisture to be added
after planting. Winter Canola uses 33% more water than corn so it is
very important to get the irrigation timing down correctly since the
irrigation season is different than corn.
Residue Management: Naked strip tillage can be used to
establish winter canola on heavy residue pivots of wheat and corn,
irrigation to 3 feet to follow strip tillage to allow light to reach
the plant and set the crown correctly, plant on strip tillage with
SRS for sure.
Once the SRS has occurred in a dry condition, the soil and seed
row saturated area will and must dry down to dissipate the Abscisic
Acid. Abscisic Acid information is included.
The addition of Zinc Sulfate improves the effectiveness in priming
of seeds….this is called Osmo Priming. Hydro Priming is utilized
with water only.
Evidently the addition of 3% Zinc Sulfate, ZnSO4, by weight improves
In winter Canola in Iran….about 35ppm Zinc Sulfate was used in Osmo
Priming. However this rate needs to be tested in Western Hemisphere
Dr. Lawrence Stoskoph from Talmadge, KS is confirming the values of
Zinc Sulfate (ZnSO4) in Osmo Priming and SRS.
Here is what happened in Iran with Winter Canola.
similarities with hot (above 65 degrees F) and dry soil (12%
moisture) SRS technique and Hydro and Osmo Priming Technique.
The goal is to discover the correct rates of Zinc Sulfate in
combination with correct rates of water to germinate Winter Canola
in hot and dry soils with variable soil stored moisture horizons.
In other words, Osmo Priming and Hydro priming may not be near as
effective as SRS in developing 99% stands of Winter Canola.
Notation. Dr. Shanahan Says, “The term is Osmotic Gradient”, per
John Shanahan, USDA-ARS and now Fortigen, “Converting starches to
sugars which absorb water more readily”. Mr. Swanson says, “This
allows the radical root to rapidly elongate with a greater diameter
and more turgor pressure for the Coleoptiles, the mystery is now a
functional part of Canola and Soybean production, and Sunflowers. “
The trigger is ZnSO4, the kick starter to break down Abscisic
Acid, The purpose of the design is convert rapidly to sugars…much
like malting barley in some respects. This is why malting barley is
flushed about 40 times in Steeping Tanks to correctly start the
germination and eventually conversion to malt and the great brews we
enjoy from time to time.
