Exactrix TAPPS makes a record in NUE at .583 lbs. N per bushel produced.  

The common denominator of nutrient efficiency in Variable Rate, Site Specific is the NUE.

The yield is coming from the 7.5 to 8 pH calcareous soils ability to timely mineralize nitrogen using No-tillage.

Nitrogen is not over applied in field areas where excessive N hurts yields.

Commercial Nitrogen must be reduced to improve yields.

Exactrix NPKS is highly crop available and in fact up to 166% to 200% more crop available.

Total Nutrient Costs are 6.92% of the gross income in Exactrix/Yielder TAPPS, highly crop available No-tillage nutrients

EXACTRIX TAPPS at 1% CV….. Uniformity of streaming flows makes nutrients highly crop available. At Colby, Kansas, December 7, 2016 a presentation was made by Joel McClure for Kramer Seed Co, Ben McClure of Hugoton, KS.

You can review the attached Power Point presentation written by Ag Economist and Manager, Ben McClure.  

Note: Two rain fall events of 8 inches total. A giant April rainstorm of 8 inches after banding and prior to planting produced confusion. Did the TAPPS nutrients move? The recommendation was to apply more N.  No extra N was applied based on correct information and years of experience with TAPPS.  The decision was based on soil samples in the band of TAPPS and consulting from TKI, Bert Bock.  The nitrogen remained in the top 24 inches in the critical Ammonium form.  The bands were very easy to find in strip till 30 inch spacing. Samples were taken twice checking out Ammonium and Nitrate.


In 2016, Ben McClure improved yields to the highest ever generated at Kramer Seed Co.
A bankable enterprise and beyond other area producers by 12% to 15% more net income.

An irrigated Kansas farm had 45% return on investment of $635 per acre invested including land and watering costs.
The enclosed circle 4 south averaged 264.00 bu./A adjusted to the scale and 15.5% moisture times $3.50 per bushel at $924.00 per acre gross income.  

The Exactrix TAPPS NUE at .583 lbs. N per bushel. The NUE or pounds N per bushel produced NH3, 141 and APP/Thio-Sul, 13 lbs. N or 154 total lbs. N came in at .583 lbs. N per bushel produced.
Ben McClure held an exceptionally good profit of $290 per acre after all costs.  Kramer Seed is in its 8th year of Exactrix TAPPS application.
The Yields were 264 bushels per acre applied on strip till/No-till 30 inch centers, in sandy loam soils, Variable Rate Site Specific at $64 total nutrient cost, Exactrix TAPPS.
The planter also had 4 planting zones that varied between 27,000 to 34,000 population, Philips Corn Seed was selected.


The Corn Yield Map was adjusted based on scale tickets and moisture adjusted to 15.5%.

The entire pivot yielded 264 bushel per acre average across the scale.
Cost per bushel for all nutrients was 25 cents.

Exactrix TAPPS, Yielder Technology required an investment 6.9% of the gross return
The rate of return was 45% of the total investment.

How significant is NUE in comparing efficiency and economy?

Is not 278 bushels per acre a much better return?

The yield on Circle 4 South produced .669 bushels per lb. of N, NUE,  and averaged 278 bushels per acre.

The Circle 4 South pivot was held constant on 34,000 planting rates. Compared to the Circle 4 North, Circle 4 South the N and P/S were over applied on average 132% N and 183% P and S. The Exactrix TAPPS nutrients were VR applied and the plant population was held constant. The N rate was 186 lbs. N average and  up to 183% more Phosphate and Sulfur was utilized at 22 gallons per acre average…and as high as 31 gallons per acre.

Compared to Circle 4 North the Circle 4 South had $50 more investment in fertilizer and seed at 45 lbs. more N, 10 gallons more of APP/ATS, a constant population at 34,000 with a Philipps variety, a 10% higher investment in seed and a 183% greater investment in Phosphate and Sulfur.

Circle 4 truly crossed over and went South with an NUE of .669.   Why? Too much nutrient with highly crop available TAPPS.

It is true that 14 more bushels were produced on Circle 4 South and additional gross income of $49.00 was produced. An investment of $50 more produced $1.00 less net income.

Yields were as high as 325 bushels per acre on Circle 4 North . Circle 4 North at .583 NUE produced $1.00 per acre more income with $50 per acre less invested.  Circle 4 South at .669 NUE was a more risky investment with a very good chance the weather could have been a lot worse. More is Less and $6,000 was at risk that did produce a negative return.

Note: Yield and application maps are available for 278 bu./A loser Circle 4 South.

Can Winter Canola Make A Difference in dryland and irrigated production?

There may be a simple and low cost way to break 300 bushels per acre in irrigated corn and make more money.
Center pivot and dryland production of Winter Canola has proven to improve wheat and corn yields by 8% to 10%.
Healthy Winter Canola is ready for winter with large crowns and no fertilizer applied. Growth regulators are improving.

Sandy soils are very much improved with a rotation of Canola, Dwarf Essex and/or Mustard.

Sandy Loam Soils favor nematodes. Nematodes are suppressed with addition of glucosinolates from Brassicas.
Winter Canola can be doubled cropped in Southwestern Kansas with Milo or Soybean to follow.

Canola crowns are growing at very low temperatures. At Hugoton producer reports indicate short in-climate temperature bursts of -15 degrees F.   
Winter Canola has improved stands with a planter spacing of 4 to 5 inches allowing the plant to develop large crowns and tap roots.
Large crowns and taproots develop improving winter hardiness with improved survival in frigid cold conditions.
The Monosem planter appears to produce the best singulation of expensive breeder seed as reported by hybrid seed producers in Alberta.

High Yielder in Deep Soils.

Winter Canola can produce yields of 6,000 to 7,000 lbs. per acre at 44% to 46% oil content in a long rotation, PNW soils.
At Hugoton,KS irrigated yields of 5,000lbs. to 4,000 lbs. per acre yield is a good start. Oil content tells the story about fertility practices and yield.

A Mustang Tool Bar P-51C is required to No-till fertilize the Winter Canola in February with
Ammonium and TAPPS for yield and oil content.
