Edmondson’s Side Dressing, X-calibar
J.B. Edmondson, Clayton, IN, 317 446 3652
Edmondson’s Clayton, IN
No-till farm is located west of Indianapolis. Their goal was to eliminate
shank application of NH3 and apply NH3 very accurately at high speed.
Accurate application of NH3 means that each corn row feeds on a uniform
even application band of NH3. Exactrix applied NH3 improves nitrogen
efficiency 30% to 50%. Now corn can be fertilized with Nitrogen with
optimum use of the material and improved corn yields of 7% to 10%. Side
dressing also improves timing of nitrogen to placement only when the crop
needs it. Remember “the soil is a lousy place to store nitrogen”

Trailer Tanks: Qty. 3 (6,000 gallons), twin 1,000 NH3 tanks on DMI steer
axle trailers, 120 inch gauge width, surge brakes. Bottom outlet valves
with Exactrix bottom outlet valve kit and safety shut down. Tanks tilted
3* for complete emptying.
Bar: Friesen, 40 foot, set up in side dressing format, 4 wheel set up on
30” gauge centers. 17 openers mounted for side dressing to match 16 row
corn planter at 40 feet. Guess Row openers are converted to full rate at
42.5 feet for preplant application of NH3.
‘Weigh Master”, Dual Manifold supplying 17 single disc openers, orifice
selection .090” orifices on 30” centers, applying NH3 at 10 mph in side
dressing or pre plant application. Coriolis Mass flow system with applied
accuracy of .006 or less (60 lbs. in 10,000 lbs. applied) and port to port
accuracy of 1%CV. Guess Row Return openers set up for ˝ rates with .064”
TruTraker and Yetter Maverick with modified closing wheels.
“Weigh Master” with turntable mount. Dual bottom outlet tanks supply NH3
through 1.25” bottom outlet valves with safety shut downs and Smarthose
Breakaways. A Coriolis mass meter weighs the NH3 dynamically in all flow
ranges. Mid-Tech 6100 TASC controller receives NH3 weight information and
determines correct speed of the sliding vane pump. Application rate is
within .006 or less of field target application rate. Exactrix primary
and final filters clean the NH3 prior to injection. Filter size allows
season long application without service.
manifolds proved to be a valuable feature with point rows. Applicators of
40 feet or greater width normally use dual manifolds. Dual manifolds are
balanced for even application.
Tool Bar folds in 1 minute to a 14 foot transport width. The Friesen Tool
Bar is commonly used with Exactrix single disc opener applications. The
Friesen Bar is known for its durability as a corn planter tool bar. Go
openers allow the Edmondson’s to No-till their 3,000 acre farm. Corn on
corn can be practiced with absolute No-tillage. Two single disc openers
were utilized. The DMI TruTraker was modified and improved. The Yetter
Maverick was also modified and improved with closing wheels. Other types
of single disc openers can be observed at
exceptionally wet spring in Indiana prevented preplant application of
NH3. Side dressing rates were applied in the 100 lb. to 120 lbs.N/A
range. Side dressing is considered less risky since less nitrogen is
required and timing of NH3 application is ideal for maximum take up of the
critical corn nutrient.
combinations of DMI and Yetter openers were utilized. Either opener was
considered exceptionally good in side dressing NH3. The closing wheels
developed by the Edmondson’s were ideal for side dressing immediate
valves were installed on six tanks. Go to
www.exactrix.com/tanks.htm for complete information. Used DMI steer
axle trailers were converted to 120” gauge centers. The surge brakes were
reworked and improved so a ˝ ton pickup trucks could deliver the twin
trailer tanks to the field. Tank hookup normally takes 10 minutes using
an extendable towing tongue.
Edmondson’s implemented test plots. The 100 lb. N/A proved to optimum for
the 2002 crop year using the Exactrix 2KD “Weigh Master”. Go to
