Exactrix News about Anhydrous Ammonia.
 Saving 100 lbs. N/A and Millions of Tons of topsoil.


Exactrix® TAPPS applied at 170 lbs. N/A produces plot averages
 of 242.3 to 257.2 bushels per acre.

In the fall of 2014 at Seward, NE, large 2.1  acre plots (STEEP Type) were applied 30 times with high uniformity resulting in 63 acres of applied Exactrix® TAPPS and TAPPKTS plus controls and comparisons to N-serve and DCD. 

Results replicated and randomized 3 times with 10 treatments produce an Exactrix® Nitrogen Use Efficiency of .660 to .702 lbs. N applied per bushel corn produced.  

The best results as Exactrix® crystalline TAPPS show 1 bushel of corn produced at .66 lbs of ammonic nitrogen fall applied.  

Abnormally high rainfall events (3.6 in.) occurred twice in the vegetative stage between May and end of June.

Large 2.1 acre, hybrid corn randomized and replicated plots were harvested at Seward/Utica, Nebraska, October 6, 2015.

The highest economic return was the Exactrix® application forming TAPPS, mixing NH3 with Thio-Sul® at 7 gallons (20 lbs. S) per acre in combination with 10-34-0 at 9 gallons (35.64 lbs. P2O5/A).  

The application of TAPPS at 170 lbs. N, 35.64 P and 20S of 2.107 acre plots 108, 205, and 310 produced a mean of 253.8 bushels per acre at a total 170 lbs N/A. This  resulted in a factor of .669 lbs. of applied N per bushel produced. 

An $11.00 per acre investment in Thio-Sul® resulted in an additional $44.00 of return at $4.00 per bushel. Thio-Sul® was the best overall performer as compared to N-serve®, and Guardian® DCD. Potassium Thio-Sulfate KTS®, was recognized as the second best performer. 

Exactrix Uniformity at high pressure streaming NH3 and liquid flow produces typical results. Also noting historical No-tillage Rotational Band Loading of 3 years in a Corn Soybean rotation improved NUE to levels of .660 to .700 lbs.N/Bu. 

The addition of an ammonic nitrogen stabilizer improved overall yields 2.5% to 6%.

Thio-Sul® at 20 lbs. S improved yields 4.5% and produced the best economic return for the investment.  Potassium Thio-Sulfate, KTS® can also be considered a good nitrogen stabilizer and, “KTS® is superior to N-Serve in yield performance”.

Heavy rainstorms occurred twice during the vegetative stage.

  

A critical note regarding mixing, crystallization and accuracy.

Mixing of the of NH3 with Liquid Ammonium Poly-Phosphate and Thio-Sul® forms a highly uniform crystal of TAPPS in a lineal dilute band width.

Highest Uniformity of metering accuracy is achieved, with low 1% CV application in liquid streaming flows assures high crop availability of placed nutrients.

Commercial Fertilizer, NH3 as 82-0-0, Ammonium Poly Phosphate as10-34-0, Thio-Sul® as 12-0-0-26S and 2 quarts typical Ammoniated Zinc 15%, Potassium Thio-Sulfate, KTS® 0-0-25-17S.  

Fall Banding occurred in December of 2014 and just prior to the winter freeze of mid-December to mid-March, 2015.

Vegetative Growing period rainfall.

There was negligible rainfall between mid-March when the soil thawed and April 16.  

Rainfall from April 16 through June 24 was as follows:

March 31—first soil sampling May 24--0.27"
April 25—started planting before rain later in day. May 28-- 0.18"
April 25-0-.52” May 29--0 .05"
April 27—second soil sampling June 2--Trace
May 04--0 .55" June 3--0.70"
May 06--3.10" June 4--1.55"
May 10--0.30" June 6--0 .60"
May 14-0.90" June 12--3.60"
May 04 to 14—4.85” June 15--1.15"

May 17--008" June 03 to 18—8.50”
May 20--0.28" June 24- -0.10"

Based on the point of diminishing returns and previous plots, the highest performing N rate the optimum N rate is between 145 lbs N to 170 Lbs N per acre.

  

Noting that previous years of testing with Kevin Medow have produced similar results.

  

Fall banding occurs during November 10 to December 10

Fall banding with Exactrix TAPPS has been successful in the past 7 years with good to exceptional yields.  

In the past, the confirmation of this top yielding technique was further explored by side dressing the growing corn with Solution 32.  

In previous years, there has been no economic response to side dressing into the growing corn with Solution 32.
