acid phosphate would give you better
formula for use on farm crops than
beans and acid phosphate. OF course,
neither cotton seed meal nor beans
should he used directly for fertilizer.
1t is very essential that they first De

ever. we prefer the cotton seed meal
and acid phosphate combination.
We cannot advise the use of the So
called rock phosphate. While ii con-
tains 81 per cent of total phosphoric
acid little of this is available. The value
of this material is also determined by
the fineness to which it is ground, the
iron and alufnina il contains, and the
character of soils on which it is to be
applied. Lands which are naturally rich
in vegetable matter may respond to the
use of this material but where one de-

ROCK PHOSPHATE FOR SOUTHERN

the value of rock phosphate for fertilzing
purposes? In what proportion should it he
used with cotton seed meal for gray pebbly
land?
A good formula to use on the land
you mention is equal amounts of cotton
seed meal and acid phosphate. Mix
thoroughly together and apply at the
rate of 800 pounds and upward per acre.
Farmers are wondering if it will pay
them to use acid phosphate. If they
expect to produce cotton under boot
weevil conditions they should hasten
the maturity of the cotton as effectually
as possible. To accomplish this there
is nothing better than acid phosphate.
A liberal ration of nitrogen should also
be used. A part of the amount of this
element needed may be obtained from
yard manure, compost and other mate
rial used under the drill row, but some
should be applied in a commercial fer
tilizer If you find something cheaper
or better than cotton seed meal as
carrier of nitrogen it would, of course,
be all right TO use it. We can not adj
wise that you use the material in ques-
tion at the price indicated.
Acid phosphate contains 16 per cent
of available phosphorus acid, whereas a
finely ground raw phosphate rock con-
Since the phosphoric acid is combined
with the lime, the lime in this material
does not exert a beneficial effect towards
correcting the acidity of the soil. The
finely ground raw phosphate rock can
be purchased here at the college in car
load lots at the rate of $425 per ton.
The price asked you for this material is,
therefore, exorbitant.

Difficult churning is due to various
things. The ration you are now feeding
tends to raise the temperature at which
churning can be successfully done quite
materially. If you were feeding a COW,
for instance. on silage and bran you
could churn the milk satisfactorily at
a temperature of 80 degrees Fahrenheit
Where you feed cottonseed meal and
hulls, however. you will probably have
to raise the milk to a temperature of 81
degrees. The chances are also that you
are not ripening the milk The process
of churning is greatly facilitated by
utilizing the AID OF what is known as
the Tactic ferment. This is produced by
certain bacteria which are normally res
ident in milk. Naturally they are much
more active in the summer time than in
cool weather. 1t is probable, therefore.
that your milk should be kept several
hours at temperature of IS degrees in
order to secure the proper degree of
ripening necessary. To facilitate quick
churning you can purchase a satisfac-
tory thermometer for about % cents.
Get what is known as the floating type.
If you use this to determine tempera-
ture and so secure the proper degree of
ripening the trouble about which you
inquire will be easily overcome.
Weevils can be destroyed in cowpeas
by the use of carbon-bisulphide This
material should be used at the rate of
pound to a pound and one-half to ton
of grain to be treated. 1t is a white
liquid with a very offensive odor, but
can be handled with safety without in
jury to clothes if lights are kept from
it. The peas to be treated should be
put into a compact bin or box and shall
low pans containing the liquid set
thereon. Carbon bisulphide is heavier
than air and will readily penetrate to
the lowest corners of the box. Several
