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 splashing.

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 mix.

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 very undesirable. 

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 corn emergence.

In winter Canola in Iran….about 35ppm Zinc Sulfate was used in Osmo Priming. However this rate needs to be tested in Western Hemisphere conditions.

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. http://www.aensiweb.com/old/aeb/2011/2208-2211.pdf

There are 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.

Scientific 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. http://www.briess.com/food/Processes/malttmp.php

Exactrix® TAPPS has Higher Yields with higher rates of Thio-Sul®, Sulfur. About 13% higher yields in high quality plots using 10.25 gallons of Thio-Sul® or 30 lbs. of S over 20 lbs. S.

AJ Foster reports from KSUCE, Garden City, KS his findings in randomized and replicated Sulfur plots. Financial help came from TKI, Bert Bock. The plots were carried out in liquid streaming flows of Mustang openers at 7 inch depths. The Exactrix applied absolute Exactrix Uniformity at 1%CV of application with 2KC and 2KM liquid Mass Flow at .003 levels of accuracy. 

The highest quality plots were soil sampled prior to the March 5 side dress application of Rubisco Hornet Hybrid Winter Canola. The 40 foot wide plots were 2400 feet in length. The plots were randomized and replicated 4 times. Oil and Protein content is coming in the next report from AJ Foster, KSUCE, Garden City regarding the Hugoton Winter Canola plots. Joel McClure dedicated 1 day to lay the plots into the sandy soil pivot of Barry Hittle.

Planted in early September,2016, The Deere 1710 planter with RRV plates on 20 inch row spacing with 60,000 to 80,000 population

At Goodland, KS, a 62 bushel irrigated winter Canola crop at 39% oil content with Rubisco Hornet harvested about July 22 to July 24.

About 7 days after harvest, No volunteer observed.

Not well understood but this could be a good second crop with cattle in the rotation or for a dairy seeking high protein Haylage.

In fact a crop of grazing or Haylage Oats could be seeded into the volunteer winter canola right after harvest of the Canola.

Raising more with Less by banding into the growing crop….Exactrix TAPPS Mustang Banding a low rate of nutrients could also be considered.

Virtually no shattered seed was observed at the soil surface on July 27th…Obviously the volunteer is coming from hail or wind damage in early July.
