    Good Management Controls
Pollution Danger Atrazine
Proper management should
eliminate potential pollution in
using atrazine to control weeds in
cornfields, according to Dr. Jon
K. Hall and associates of the
Agricultural Experiment Station
at The Pennsylvania State
University. '

hundredths of a pound per acre-a
negligible figure.
The experimental site was
planted in a manner to induce as
much chemical loss as possible.
The corn was planted up and
down the slope instead of across
the slope as recommended. The
slope of 14 per cent was rather
steep, giving a drop of 14 feet for
every 100 feet.
Even in a year with intense
rainfall early in the season, loss
from “washoff" was only 9
hundredths of a pound per acre.
Dr. Hall claimed such losses
would have to be considered
minor due to the nature of the site
and the soil and crop
management practices used.
It is obvious, Dr. Hall affirmed,
that various chemical, biological,
and non-biological forces in the
soil and in the corn crop act to
Regrade the original herbicide.
soil core studies revealed that
the atrazine was broken down in
the soil at a moderate rate. Also,
more than half of the chemical
reacted with the topsoil and was
held there. Measured one month
after application, atrazine had
dissipated to 39 per cent of the
amount applied at the 2 pounds
per acre rate of surface ap
plication. Three months later the
atrazine was down to 9 per cent of
its original amount.
Dr. Hall said the flood con
ditions of 1972 created only
slightly over 5 hundredths of a
pound per acre “washoff” of
“Herbicide losses in the total
studies were not as serious as
losses of water and soil which
were considerable at times. The
results speak strongly for sound
soil and crop management
practices to combat erosional
problems,” he affirmed.

Lean to Shop for Money
Are you really as smart a
shopper as you think you are?
Sure you shop around in differ
ent stores comparing prices and
quality. And because you do,
you can tell when a genuine bar
gain is available and determine
its value.
But, the Pennsylvania Bankers
Association asks, do you shop for
money when you need it? That's
right, shop for money.
What is shopping for money?
It’s another way of saying, do
you compare interest and finance
charges on loans or credit pur
You should, advises the Penn
sylvania Bankers Association.
There is a difference in rates you
The slight loss of atrazine was
reduced considerably more in
1972 by adding a broadcast
planting of oats adjacent to the
com at the bottom of the 14 per
cent slope. This small block of
oats further reduced chemical
loss by 87 per cent. Furthermore,
no atrazine toxicity symptoms
were detected in the oats.
In addition to atrazine, the
studies included two ex
perimental s-triazine herbicides.
Losses for one of these ex
perimental herbicides, related to
atrazine, were equally slight.
The Penn State soil scientists
also examined the effects of an
experimental s-triazine herbicide
applied to alfalfa. Runoff water
was very slight, no sediment was
ever collected, and the con
centration of herbicide was ex
tremely small.

I'd like to do a little exercise in math today.
Let's assume ear corn costs $50.00 per ton, a
32% natural protein supplement costs $9.00 per
hundred, molassas costs $4.00 per hundred and
Cargill C. L. S. controlled release liquid sup
plement costs $5.00 per hundred.
If we want to make a fifteen per cent protein
ration using the above ingredients, it would
cost $98.50 as here itemized;
700 pounds of 32% sup. at $9.00-cwt
1100 pounds of corn at $2.50-cwt
200 pounds of molassas at $4.00-cwt
If you used Cargil C.L.S. it would cost $87.50 as
itemized here;
500 pounds of 32% sup. at $9.00-cwt
1300 pounds of corn at $2.50-cwt
200 pounds of CIS at $5.00-cwt
Of course you must add mixing costs to both
examples, and prices on all ingredients will
vary with time and location. Work it out with
the figures you pay. And if your dealer can't

have to pay on borrowed money.
Maybe you never thought of that
credit card as borrowed money,
but that’s what it represents
when you don’t pay your bills
within the specified period of
time, because the card issuer has
paid for the merchandise. If you
don’t pay him on time, he in
effect charges you for the money
you borrowed.
Although there are state regu
lations which set the maximum
rate you can be charged for bor
rowing money, not all banks and
companies charge the maximum.
Often you’ll find there’s a sig
nificant difference in rates. And
if you’re buying a big-ticket item,
such as a new car, the difference
in charges for borrowing money
can amount to hundreds of dol
lars over several years.
So follow the advice of the
Pennsylvania Bankers Associa
tion. Learn to shop for money
the next time you’re buying
something on time. You’ll find
it's a good way to make your
money count!
