Trace Minerals May Be
Through plant breeding and
fertilization, crop yields have
increased enormously for sever
al decades.
The more or less standard
NPK fertilizers, heavily applied,
stimulate rapid growth and pro
duction of crops that pump up
through the root system not
merely the three commercial
plant food elements, but also
other mineral elements includ
ing trace minerals with which
we are concerned, according to
Dr. Gustav Bohstedt, of the
University of Wisconsin.
If these minerals are not re
placed in time, the soil will be
come more and more depleted.
The New Hampshire test
some years ago is a case in
point Through successive NPK
fertilization pastui es finally
were found to have only about
half of the cobalt necessary to
satisfy the requirement of dany
cattle.
Should cobalt then be added
to a fertilizer application as a
New Zealand friend suggested
at one time? Not unless cobalt
were much' cheaper than it is
in our country, Dr Bohstedt
said. Added to the feed of cat
tle one can get by with about
1/15 of the cost necessary to
properly fortify the pasture

The combination of Du Pont "Lorox" plus Atrazme gives you
the best annual weed and grass control for corn . . . while
minimizing the carry-over problem. "Lorox" is known for its
favorable rate of disappearance from the soil as well as for its
superior ability to control a wide range of weeds and grasses.
Atrazine is known for the manner in which it is tolerated by corn.
Mix them yourself or buy a ready-mixed formulation of the

the midwestern corn belt.
The late Frank B. Morrison
in his text and reference book
FEEDS AND FEEDING, at the
beginning authored by Dean W.
A. Henry, gives analyses of the
major feed crops for several
decades.
Taking the editions of 1913
and 1956. the iron content as
reported in appendix tables of
the book declined 75 per cent in
corn, 62 per cent in barley, 74
per cent in oats and 54 per cent
in timothy hay
Heniy and Morrison used
many feed analyses from dif
ferent parts of the country in
an effort to obtain as depend

the mass of data might have
some statistical significance
