With about three and a half
million acres of land the U.S.
could assure itself a per
mament supply of fresh
water.
Dr. Louis -T. Kardos; en
vironmental scientist at
Penn State, revealed this
and even more striking
evidence of the recycling
capacity of soils to the
Seventh International Water
Quality Symposium in
Washington last week.
The figure is based on land
requirements of the sewage
recycling system developed
by Kardos and others at
Penn State over the psst
ten years.
Three and a half million
acres is less than a quarter
of one percent of the total
land area of the U.S. A
relatively small investment,
he notes, for the pure water
it could deliver.
The system involves the
spraying of treated sewage

fit to drink by percolation
through the soil where
microorganisms Join with
soil characteristics to filter
out impurities.
Kardos, a member of the
University’s Institute for
Research On Land and
Water Resources, called
attention to the prodigious
capacity of topsoil to react
with bacteria and viruses
and “filter” them, as well as
chemicals, out of
wastewater.
Billions of
microorganisms inhabit a
mere pinch of topsoil. In
addjtion, a good soil makes
available huge surface areas
for the filtration effort.
One clod of loam no bigger
than a cube of sugar may
contain 200,000 square inches
of surface area.
A single plant (rye) in such
soil vastly enriches its

The American Soybean
Association (ASA) is
developing a book on the
history of soybeans, but
needs help. Anyone with any
historical soybean in
formation should get in
coiftact with ASA.
Kent Pellett, retired editor
of the Soybean Digest, has
been assigned the task of
researching and writing the
history.
Pellett wants to hear
from anyone who can tell
about changes in soybean
production, marketing and
utilization. Important
changes involving soybeans
have taken place in
varieties, machines row
widths, feeding practices of
livestock, marketing
procedures and use in the
human diet.
Anyone with information
to submit to Pellett can write

It will have 14 billion root

“This makes clear,”
Kardos says, “why we have
dubbed our system the
Living Filter. The land
biosystem appears to be
unexcelled in its ability to
purify water.”
