COOK constructed this fertilizer/drill for the family
Ririe, ID, wheat farm. He built a cart from a Yielder
drill frame to carry a 3,000 gallon anhydrous tank, two
700 gallon liquid fertilizer tanks with an Exactrix
TAPPS system, and a custom-built AgPro 10,000 pound seed
tank. A John Deere 1895 drill follows behind.
Cook bought a new Case IH Quadtrac 535 with second hydraulic pump
to pull this massive one pass rig.
The Deere 1895 is set up with
Exactrix TAPPS Mid Row Banders on 20 inch centers for
dryland and irrigated winter
wheat and spring wheat production is designed for single
pass or two pass programs.
The new series 3 Deere boot can be reviewed at
The machine will also side dress winter wheat in the
spring or fall with 15 inch band centers.
The frame of a Yielder 1520 was utilized to support the
38,000 pound payload with the large 30.5 x 32, R-3-0
tires. Turning is accomplished with a Yielder, load
bearing, six inch ball and socket hitch. The load
bearing hitch design balances the machine keeps
compaction potential low. You can review this in the
The seeding width is 520 inches.....or 43.33 feet.
For 2008... the field wide average yields for soft white
winter wheat irrigated winter wheat was 135 bushel per
acre. This is a good yield for the area and the 2008
year. Some years the yields can be even higher depending
on the fall start and length of the winter....up 160
bushels per acre is achievable with favorable winter and
good early spring weather at this high altitude.
The average yield for
irrigated Hard Red Winter Wheat production was 125
bushels per acre.
The 2008 Exactrix TAPPS applied fertility program for
the irrigated winter wheat was side dressed at 3 leaf to
4 leaf growth stage...... a side dress of TAPPS at 120
pounds N, 10 gallons APP/ATS was good enough to raise a
strong and standing winter wheat crop. No lodging was
ever observed in the fields indicating again that a
uniform application of TAPPS had been made.
The nutrients were single disc banded on 15 inch centers
into growing April wheat. Virtually no damage occurred
to the growing wheat with the side dress technique. The
Deere single disc openers can side dress winter wheat
without damage. The technique occurs as the winter snow
pack leaves the irrigated production area at 4,800 feet
of above sea level.

the treatment and the big seeder operating in the 2008
Under extremely dry growing conditions the annual crop
dryland winter wheat was in
the 30 bushel range.
Fallow winter wheat is not considered competitive with
No-till winter wheat at current wheat prices.
The dryland winter wheat proteins were in the 14%
to 15% range.
Blending of irrigated and dryland winter wheat will
raise the protein for a top price based protein grades
