Butler forms scale group
FORT ATKINSON, Wi. - Butler
Manufacturing Company has
created a Scale Group that will
manufacture, market and service
electronic scale systems currently
used on Butler’s feed mixing
equipment. The Scale Group is a
separate unit and will be
headquartered in Fort Atkinson,
WI.
The Scale Group was formerly a
department of the Butler Livestock
Systems plant in Garden City, KS.
Larry Hayes, president of Butler
Livestock Systems, said the
decision to create and relocate the
Scale Group, “resulted from
establishing Fort Atkinson as the
focal point for product research
and development.”
Hayes added that the Scale
Group product line has been
successful in feed system ap
plications, and now Butler
Livestock Systems believes there
is more potential for these scale
one part S. Using a nitrogen-sulfur
solution such as Suran (28-0-0-4 S)
will help prevent and correct S
deficiency and keep N:S ratios in
line.
Band all P and K: Fertilizer can
be surface banded (dribbled) or,
for even greater efficency, deep
banded four to five inches beneath
the soil surface. Most spray booms
can be tooled up with drop hoses
for surface banding. Deep banding
is often combined with preplant
tillage, usually chisel plowing.
systems in applications outside
existing product lines.
John Stewart has been named
vice president of the Scale Group.
He was formerly vice president
and controller of Butler Livestock
Systems. Steward has 12 years
experience with Butler in financial
and market research positions.
Bruce Johnston, named product
manager, had a similar role in the
former Oswalt Division operation
in Garden City, KS.
Butler has manufactured
electronic scale systems for
mobile feed mixing equipment
since 1981. The Garden City facility
designed and manufactured strain
gauge load cells while the scale
system’s microporcessor-based
electonic indicators are
manufactured by another Butler
operation, Pacific Technology,
located in Seattle,
Tanks can be mounted on the
tractor, three-point hitch, tillage
tool or on a separate trailer.
Apply N with P: Applying one
pound of N for every three pounds
P 205, together in the same zone,
will enhance phosphate efficiency.
Further research has suggested
that a 1:1 ratio of N and P will
produce even better results. When
using 1:1 ratio, fertilizer should be
placed at least three inches from
seed to avoid seedling damage
from phytotoxicity.
Use a starter fertilizer: A starter
band will support the crop until
roots make contact with preplant
band. Starter is also a must for
early-planted corn and con
servation tillage programs, where
cool, moist soils can limit crop
uptake of P 205. A clear-liquid
polyphosphate solution such as
Poly-N (10-34-0) will sequester
metal ions of certain
micronutrients and make them
more available to the crop.
