Here
is the economic analysis, between $78 to $96 per acre for Exactrix
TAPPS will raise a good crop in 2015.
Fall Banding Nutrient Budgets for the 2015 corn crop,
Irrigated production.
Exactrix
delivers 12% more net with TAPPS…a powerful economic punch in the
cost price squeeze of 2015.
Using the economic method to confirm application rates in fall 2015.
2015 Corn acres reduced, Soybean acres increased.
Here are the
calculations for your TAPPS fertilizer budget.
Futures Price Sept. 2015 at $4.02 per bushel corn, Predicted nutrient
pricing for 2014 fall based on $3.65 corn.
1. Nitrogen. $500 per ton NH3, 30.5 cent N,
2.
Ammonium Poly Phosphate or APP at 62 cents per lb P.
3. Ammonium Thio Sulfate ATS at 50 cents per lb S.
Budgeting
with 210 bushel per acre yield potential. Irrigated Western Kansas.
Maximum Economic Yield of 199 bushels per acre per data sheet included
below with 2008 nutrient costing…similar to 2014
Per acre Rate at 150 pounds N
35.37 gallons per acre, 40 lbs. P (10.25 gpa) and 15 lbs S (5.25 gpa).
$78.05 TAPPS. TAPPS with Zinc. $83.05.
Gross Income at 199.1 bushels per
acre. $800.38 as per enclosed 2008 test plots.
$78.05 Banded Fertilizer costs subtracted for a Gross Margin of
$722.33
2015 Producers with Exactrix TAPPS can invest up to $96.00 per
acre or 12% of the gross income in nutrient costs with corn at $4.02
per bushel

Ben McClure at Hugoton, KS
reports in his 2008 plot data. Ben also operates Kramer Seed Farms
which is a winter wheat seed supplier. This is a large center pivot
farm in western Kansas.
Ben's results are on large plots with 28 total plots under a center
pivot with Garret Havel, Crop Quest Agronomist, assisting with the
data. The plots meet Steep 3 criteria and are harvested with a weigh
wagon.
We are confident this is a good set of data.
Applications of TAPPS with N above 150 pounds per acre, creates a
backside of the nitrogen yield curve. Yields do go down above 150
pounds N quite often with Exactrix Application, N rates must be
reduced to take top yields.
The Marginal Return Point is between 126 pounds to 150
pounds N, a good bet is 140 pounds N is about maximum with 30 inch
band spacing, making a one time application.
Exactrix does apply 166% more crop available nitrogen. Across the
Great Plains, the system does apply 200 % more crop available
P when you include P and S with Nitrogen.
