interest to those attending
the convention was the
agricultural use of sewage
sludge, with the topic being
discussed by Raymond
Shipp, Extension agronomist
of Penn State.
Shipp stressed that if
anyone uses sewage sludge
for crop production, whether
it be for corn or vegetables,
they should first know the
contents of the sewage
sludge. Knowing exactly

what is being put on the
fields is very important, he
added. A complete chemical
analysis can be done at Penn
State by the sewage sludge
testing service, and anyone
interested in having this
done should contact their
county agent. Cost for this
service is $lOO per sample.
There are many ad
vantages to using sewage
sludge, Shipp explamed. It

nutrients. Sewage sludge is
basically organic matter.
When it is added to the soil, it
is good for general soil tilth,
and increases the water
holding capacity of the
ground. The soil structure is
improved. The essential
micro-nutrients are also
contained in sewage sludge.
These are the necessary
elements needed by plants in
very small amounts.
There are disadvantages
to using sewage sludge, too,
Shipp continued. It contains
heavy metals, and while
some heavy metals are
essential plant micro
nutnents, others are not.
However, all will persist,
and build up in the soil,
accumulating. Some heavy
metals, such as cadmium,
are not only non-essential
but also highly toxic to
animals and humans. These
metals are taken up by
plants quite readily, and
thereby being incorporated
into the food cham.
Cadmium is unique and
important to consider in the
fact that very small amounts
of it (one to two parts per
million) can result m
significant amounts of
cadmium in plants grown on
that soil. Whereas it takes
from-10 to 70 parts per
million in soil before cad
mium becomes toxic to
plants, plants growing in a

soil amended with high
cadmium-containing sludge
represents a food chain
contamination hazard. Yet
those plants will show no
toxic effects in yield
production.
Shipp stated that sewage
sludge has been used on land
for years, yet its contents
have never been examined
before. He believed that it
will be used more in the
future, as sewage can no
longer be dumped m the
ocean and land use becomes
more necessary. The sludge

FRA Series Vacuum Suppliers.
The FRA Series supplier is a high-capacity, fast
recovery unit designed to handle milking
systems of all types and sizes. They provide
smooth, constant air-flow, with sufficient
vacuum reserve so necessary to proper milking
efficiency.
BOU-MATIC offers the FRA Series suppliers in
two basic styles: As a pre-assembled, belt
driven unit, mounted on a 30 gallon stainless
steel reserve tank; or as a pre-assembled Direct
Drive unit for use systems where a balance tank
is installed.
Either way, a BOU-MATIC FRA Supplier
properly sized to your system requirements, will
will prove a most profitable investment towards
better milking for your cows.

would be better to use, he
added, if industry would
remove the harmful
elements before sending it to
a sewage plant. This process
is known as pretreatment.
“I fmd it strange,” Shipp
related. “On all chemicals,
there are labels telling
exactly what is m the
mixture, and people are told
to read those labels carefully
before using. Sewage sludge,
however, has no labels, and
the use of it without knowing
its contents is dangerous.”
