A No-tillage Legacy Moment,
Investigating Seed Row Saturation with Planters.

A good look at planted wheat with SRS.  

Seed Row Saturation, SRS at 50 to 100 gallons per acre at 20 inch seed row spacing.   

Exactrix Mustang TAPPS banding to follow shortly along the row. Banding 7 to 8 deep in No-tillage.

Bumper Flats is about 3 miles from Joel’s  homestead house and 5 miles from Rattlers Corner where Winter Canola has been under review.  



Joel and Jay McClure, Deere 1790 Planter set up on 20 inch with Precision Planting equipment installed. Milo plates were used to plant 12,500 seeds per lb. from Kramer Seed Co.



Hello world, it is a beautiful day in my field with 225,000 population on every acre. I have high quality soldiers on every acre marching off  to war.

“My eyes have seen the glory”.  My soldiers are singing “The Battle Hymn Of The Republic”.  

This is healthy wheat on the Great Plains.  

Who said the seed rate was “a bushel and a peck”?  A peck will do finely. The left over bushel can make more cakes, noodles and bread.


October 27, 18. McClure, Bumper Flats, Jay and Joel McClure reporting with the camera. 

Ready for hybrid winter wheat at $8.00 per acre seed cost? A good population would be 225,000 to start with and then go lower in testing but SRS must be in service.  

Planters space the seed closely together and SRS becomes highly functional due to the opener and seed tube design. The 1790 Deere planter’s soil V and soil W slot force the seed tightly together. The seedlings race the roots deeper and compete completely for light due to the metered seed and correct in row spacing. The Swanson offset leading double disc metering opener has proved that point with a unique soil W and metering of the seed by the opener. 

Hill planting will provide similar results for spring barley.  

Planters also have good row cleaners that remove residue from the row area. The residue removed can be straw and corn stover or it can be soil active chemicals.  

The row cleaners must just skim the soil surface as shown in the above picture.  

This field also received about 4 inches of rainfall in October early.  

Planters are seldom limited by residue flow at 20 inch spacing. In fact 20 inch corn on 20 inch corn in No-till works very well.  

Planters are also very wide and seed slower to provide 500 to 750 acres per day at 60, 80 or 90 feet. A 20 inch row space planter at 60 feet is a big planter.  

Another reason planters are desirable in winter wheat country is the use of Hybrid Winter Canola for money and for fumigant cover.  

Hybrid Winter Canola is a fumigant crop. Hybrid Winter Canola can be also used as a cover crop when the price is low and corn is a better choice in the spring.  

Mustang P-51C openers applying TAPPS allow nutrients to be managed to the maximum efficiency.  

Hybrid Winter Canola needs no fertilizer if the crop is only for cover and fumigation.



Yes sir, 20 inch spacing is just fine. In drilling winter wheat in Washington State the USDA-ARS, Dr. Jim Cook discovered that 28 inch was the down turn in row spacing.  

Wheat rows in 7, 14, 21 yielded the same. At 28 inch rows the wheat yields dropped 3 per cent.  

The test was completed with a 7 inch double disc drill at Pullman and Lind, Washington.  

Basically stated 2 out 3 rows were used to control weeds. The third row was for yield.  

Much of our knowledge on how to raise winter wheat is simply incorrect in today’s world of hybrid genetics and No-tillage farming  

Mort and Guy Swanson discovered that more seed rows of winter wheat were cumbersome to No-tillage. More rows actually lowered yields in following crops due to cool and wet soils in the spring.  The winter wheat residue produced was too much on 9 inch rows. Thus No-till farmers started to burn their stubble.  

The first No-till Drill in the PNW “Old Yeller” was set up at 9 inch row spacing. The drill was then modified with row cleaners to 18 inch row spacing producing superior performance in winter wheat. Bigger heads resulted and the straw to grain ratio was improved. For sure there was more grain and less straw on 18 inch drilled seed row spacing with offset leading double disc openers that metered the seed.

SRS made a big difference.   

SRS flushed the Abscisic Acid from the seed. This is also referred to as “Steeping” by maltsters.  The design also made a Vapor barrier which is referred to as a Reverse Feeder Dike.  

SRS is also a form of weed control.

Ready for side-dressing winter wheat, Mustangs go deep to 8 inch depth with No-tillage. TAPPS and TAPPKTS.  

Joel and Jay McClure inspect a new Mustang P-51C tool bar with 25 inch single edge blades at Keating Tractor, JD dealer at Liberal, KS.  

Mustangs will be aligned parallel to the 20 inch rows at 8 inch depth.  Askew treatments can also be made.  

Weed control is anticipated to be better with bands located 1 to 2 inches to the side of the rows.  

About ½ the nutrient is required.



A good fall start.  

The Exactrix designed SRS flushed the Abscisic Acid from the seed and combined with the quick start make the 20 inch seed rows emerge together.

Controlling weeds with planters, row cleaners and Exactrix® SRS water in the row at 50 to 100 gallons per acre. 

Row cleaners removed chemical residue and straw and 50 to 100 gallons per acre of water flushed the Abscisic Acid from the seed.  

No sense raising weeds when it is wheat that we need.




“Old Yeller” seeding 18 inch winter wheat with Duff Scuffers. Duff Scuffers cleared the path for the offset leading disc openers.  

Urea was metered to the side of seed row…and the Duff Scuffers covered the volatile urea band. The volatile urea was sitting at the surface and covered with duff.  

The relationship of Urea in surface bands to seed rows was not correct.  Dr.  Fred Koehler, a WSU fertility expert proposed banding nutrients below the seed rows to get high utilization of place nutrients.  

This was also a backfire since the nutrients were too close to germinating seed using the 16 inch spacing HZ split Packer design of drill with extended seed boots. Dr. Gary Hyde, WSU was involved in this development of modifying the 16 inch HZ Split Packer. 

As per the picture above. In 1978 the Urea was above the 18 inch seed row in a concentrated 18 inch band. This technique was a backfire on steep slopes as gravity allowed mobile urea to reach the seed row.  

The 46-0-0 and 40-0-0-6S Urea and Urea Gold was able to move downward and to the side and into the seed row and hurt the germination of both winter and spring wheat.  

The is last year for Old Yeller in the Fall of 1979…Nitrate 34-0-0 had been eliminated in 1978 and now Urea was questionable for top yields in Winter Wheat.  

By the 1980 the first Yielder Pioneer drills banded nutrients below the seed row and to the side on 7.5 inch spacing. The Urea bands were typically 4 inches in depth and between the 7.5 inch rows.  

By 1983 the use of Urea was ended with the Yielder® Drills. Yielder Drills banded nutrients on paired rows using Aqua Ammonia and Anhydrous Ammonia and 16-20-0-14S in a common band.  

Then in 1983 and 1984 yields started to jump using Yielder® Paired Row seedings of 5/15 and 5/10. 

Yielder Paired Row 5/15 is seldom duplicated in wheat production.




What about wide seed rows….Good weed control is required in a wide space, 18 inch seedings of winter and spring wheat.

SRS also helps to control weeds under pivots. The wheat gets the water and weeds starve.



The motorcycle made the correction at the ridge tops. The big engine held the ground speed constant on 3 D-6 track frames that oscillated independently.



Weed control of peas is accomplished with FMC, Sinox W,  Dinitro which was a differential wetting agent desiccant.  


How the world has changed since 1983.

Banding to a 5 inch depth between 2 rows 5 inches apart produced the highest technical yields of the time in 1983 thru up year 2,000.  

Yielder Paired Row provided a major change in No-tillage in the western US.

In 1983 the recommended rate with old fashioned metering equipment in No-tillage and Tillage required a lot more nutrients be applied.  

Today…that recommendation is 100 lbs. to 120 lbs. N as NH3,  20 lbs. P as 10-34-0 and 20 lbs. S as 12-0-0-26S with 1 lb. Zinc to raise 100 bushels per acre winter wheat in No-tillage Exactrix Mustang Banding at the 7 inch to 8 inch depth.

The P-51 Mustang Deeper Bands are key with 12 and 15 inch bands of TAPPS with Micros applied at 1%CV in an acid/base reaction.
