Potential Reasons for Weakened Ear Shanks and Ear Loss

A recent report on Corn Crop Quality in relation to the disease
problems of 2017 Nebraska Corn crop.

Typically
Solution 32 application on Spring Wheat and Spring Barley leads to
similar disease problems found in corn, such as Fusarium and Downey
Mildew and a lodged crop, both Fungus and
Bacterial diseases do a lot better with copious amounts of nitrate.
Highest quality
brewing barley is always raised with Ammonium. A plumb kernel at 50
lb. Test Weight is produced for the Maltster with TAPPS and TAPPKTS.
How critical it is to keep Fusarium out of Brewing Barley.

A review of harvest diseases of corn. Jackson Ziems, Rees, and
Haverson points to the solution.
I am wondering
if the scientists have just recently discovered that the over
application of nitrogen can cause ear rot and fusarium problems and
bacterial diseases in a mix. It should be
noted that the type of nitrogen creates most of the problem.
The key point is
the type of nitrogen causes most of the problem.
The scientists are not talking about Exactrix Ammonium in a balance
of NPKS. They are talking about in season Nitrate.
Most producers
cannot read through the problem since N is all types of Nitrogen.
-
N as NH3,
82.4% as the only form of Primary Nitrogen,
-
Urea at 46-0-0
3rd World Source, Conversion required to release CO2.
-
UAN at 28-0-0
for Salvage and Convenience and very expensive.
-
Aqua Ammonia
at 20-0-0 for minor use of modified Primary Nitrogen.
Unbalanced rates
of 32-0-0 applied with an inaccurate pivot that can bring on disease
problems of corn ears, leaves and stalks.
The corn cell
walls are thin and have deep green coloring of leaves. The extreme
deep green color shows the effect of thin cell walls in the leaves
and stems.
The result of
the copious rates of N creates an extreme nitrate rich plant and a
great target for Fusarium.
Correct rates of
TAPPS and TAPPKTS seldom produce this thin cell wall problem mainly
because of Uniformity, Balance of Nutrients, and Ammonium Nutrition.
The corn plant color is Steiger green.
The one key
point in the document is balanced nutrition....and begging for
Potassium in the mix. Which means this material must be placed in
the soil for best effective use.
I found the
article to be critical for our Exactrix owners,
with the consideration of TAPPSKTS with a complete micro
package.
A major point in
the production of Corn, keep the nitrate
away and off of the plant tissue.
Always consider
a complete pre-plant package of TAPPKTS....any salvage or
convenience application of 32-0-0 is extremely rare with proper
advance planning.
Fusarium does
well with a thin cell wall. Often generated with foliar applications
of Nitrate, Solution 32 and or 28. Avoid it and raise more with
less. In fact Less is required to Raise More.
