Ammonia Efficiency Jumps Ahead. Eric Odberg Goes to School.

How to Raise No-Tillage Spring Grain With Paired Row Openers and Exactrix TAPPS and TAPPKTS plus Zinc.

A good way to determine “Paired Row Opener” fertilizer efficiency is to measure the barley yield, the plump kernels, the percentage of thin kernels, the  protein levels, and bulk density or test weight of the samples.  

Paired Row Openers are known across North America to have top fertilizer efficiency hiding fertilizer from weeds and making NPKS perform at 166% to 200% better levels of crop availability.

Here are a few notes to review before studying what happened in the spring of 2022 at the Eric Odberg farm.

The Malting barley was over fertilized, a good example is shown in this picture as the barley is tipping 15 to 30 degrees. This tipping of the stem can reduce an even fill of the two row head. It is the even filling that assures the plump kernel with no thins. It is very easy to over fertilize Malting Barley with Paired Row openers.  

This was a good crop for the area of Genesee, Idaho…well above average and exceeding all other fields to our knowledge. The two row variety of Malting Barley is Connect. Yield 5,330 lbs. per acre. Protein is 12.8%, Target Protein should be 9.5% to 10%. Thins were 8%, 5% is max without a dock. Test Weight was 55 pounds per bushel.

The 2022 year had high heat in July following a good rainfall start in May and June at below average temps.

Within 30 days of harvest the crop was made.  

Malting Barley Quality Specifications - Deer Creek Malthouse

Optimum Malting Barley Protein is between 9.5% to 12%. We have determined that it can go to 13% protein and as low as 9.5% protein. A very broad range of 3.5% .  

The ideal protein content for malting barley resides between 10 and 12%, and too high or low a protein content can negatively affect malting quality and, therefore, Page 3 Foods 2021, 10, 1389 3 of 21 brewing capacity. Jun 16, 2021.

Each 1% of additional protein in Spring wheat requires 30 additional pounds of N…and not always applied as the soil easily contributes the N without placement N.  

Protein in Base Malt — BrewChatter 

Thins must be 5% or lower. Thin barley berries result from drought stress and too much fertilizer.  

Low plumpness and high protein mostly are attributable to high temperatures and moisture stress during grain filling. 

High proteins are also related to high efficiency of the fertilizing opener.  

The Paired Row Opener is very efficient….and there is no need for seed row starter in spring wheat. Especially under drought and plant stress from lack of soil stored moisture in the root zone.    

  • If your TAPPS or TAPPKTS bands were in the soil Mustang style with 1% CV at a 7 to 8 inch depth you would again have changed the drought stress game. Roots flourish where you place fertilizer.  
  • You must be aware that this Exactrix TAPPS and TAPPKTS plus Zinc paired row opener is very efficient….and drought stress requires much deeper bands. Thus seed row fertilizer hurts yields.


  1. Recommended applications, Following the Ortho Ratio, 27-12-0-7S. Yielder Paired Row Seeding vs 10 inch Yielder Seeding….nutrients are much more crop available with paired row seeding. Most often 30% to 40% more efficient.   

    The Yield jump is 20% in spring crops and 10% in winter crops as compared to 10 inch Mid Row banding 1895.  

    It is very easy to think that your old rates are correct…..the rates must be designed around the opener as per my previous comments.  

    Paired Row may require testing of rates and quality. This is a very big deal long term….we are talking millions of dollars over the next 20 years.  

    Always remember the soil raises the crop….not the fertilizer….The fertilizer is a stimulant….Fertilizer can hurt yields. Poor opener design can hurt yields.

    With No till old TAPPS and TAPPKS  bands remain crop available…..and you are now producing deep bands 180% faster for future crops using TAPPS and TAPPKTS plus Zinc. 

    Follow the Ortho Ratio.  And always use Ammonium….No nitrate. Ammonia is Amino, Only Amino can single step or directly form amino acids or proteins. 

    Nitrate is a two-step operation to make Amino Acid and there is a 17% energy loss.  

    If you need more volume with liquids to improve the flow…..use K-Row 23. Never use Nitrate in the row.  

    On winter wheat you should try 2.5 gallons of APP and 3 gallons of K-Row 23, you can try it in re-crop winter wheat or winter wheat on spring wheat to control browning root rot over the winter….but  do not use on legume soils.0

    Remember….always remember….all starter fertilizers use Ammonium NH4 and never nitrate, NO3.

    Like you  and I have learned this over many years of testing and working with the UNL, Dr. Schepers.    

    1. Barley and Western Soft White, Spring and Winter.  Your average rate, 54 lbs. N- 24 lbs. P-0-14S. Go to 4 to 5 gallons of KTS or K-Row 23  to stiffen barley straw.   
    2. Protein Wheats Spring and Winter, VRT starts or averages, 81-36-0-21S plus micros.  
    3. No seed row fertilizer in spring crop….as this causes high root set and drought stress and thins.  
    4. Use PGR to shorten the barley straw. PGR is Too tricky on wheat. PGR on Malting and Feed Barley is worth 500 to 1,000 pounds more yield. Work with Kevin Melville.

    Eric Odberg at Genesee, Idaho,


    Spring soft white club wheat, Spring club- 73.08#'s of nh3, 20.14#'s P, 30.63#'s S, 4.02 #'s Zinc, 2.01#'s boron. 


    “I really don't think I over applied.” as per Eric.


    Spring Club was applied with too much N. It  has 91 pounds of N total when 30 to 40 pounds N would be fine.


    And the Spring Club was probably 10.8 to 11 % protein  If your protein came at 11% or 13% you need to reduce by 30 pounds N to 60 pounds N to make top notch soft white western white. Your goals are milling quality for the orient. Fine cake flours with low protein is the market…..and also some blending of flat bread in the Orient requires low protein. Western White Milling Wheat is about 10% Club Wheat and 90% Soft white.   


    So N is overapplied about 30 pounds N to 60 pounds N….which means you probably need only apply 15 pounds of N as NH3 with 18 pounds of ammonium N from the P and S.  This means 9% protein. A protein of 10% is also fine . You need to stop with the extra money as you took a  loss of $24 at 87 cents for N.


    Opener root geometry and design changes the rate and the efficiency. The root pattern geometry makes a big difference. Your old 1895 is good machine but has been surpassed by high fertilizer costs. Thus MRB with old fashioned non placement openers results in poor economics. The fact is that 30 pounds of Applied N equals 1% protein. You have much higher efficiency.


    You are missing about $40 per acre in your bank account mainly because you have a very efficient opener…..and always remember that the fertilizer you buy is only a stimulant with this advanced designed opener….the soil provides most of the nutrients.


    It is also good news to learn that you can reduce N by 60 pounds….since 105 pounds of lime per acre would be required to overcome the 60 pounds over application of N.  This adds another $10 into your bank account over the long run….


    So the real savings can also be added up and by the time you add reduced fill time…you probably have $55.00 to add back into the bank account next year.



    Total N was too high in Highest Quality Malting Barley using the Connect variety. It is a fact N rate must be adjusted downward.  This opener built by Ag Pro and modified by Exactrix gets a endorsement for top nutrient efficiency. The opener is performing at a very level and now the nutrients are not plant food. They are stimulants.


    Malting Barley is further discussed below.


    Don’t forget….white wheat protein does not come with a premium. And low protein in white wheat is desirable in all markets. When nitrogen costs so much per pound of N at 87 cents….you could have another $55 per acre because of uniformity and the opener.


    These new machines, Ag Pro and Exactrix are million dollar decisions over time…. Test Plots must be completed, the AgPro Exactrix Opener and 1%CV of application is changing your program.


    Spring soft white should be in the 9% to 10% protein range.


    Roger Wilson, TVA, WSU, Phosphate expert,  told me one time…..with regard to Nutrients and Protein….His comment. “Always remember Guy”, “Wheat makes yield first….and protein second.”


    If you are not getting paid for protein….the rates need to be reduced due to the opener.

    The sulfur may also be too high for soft white spring.


    It is the opener on 12 inch band centers and average 6 inch rows that is making the big difference.


    Test, Test, Test….next year.
