Fertilizing Crops With COttonseed
Meal


w. F., Limona, Fla, writes:
have some cottonseed meal
which shows the following analy-
Sis: Six per, cent ammonia,
per cent phosphoric acid, Is per
cent potash and per cent fat.
Is this in an available form?
Could phosporic acid and potash
be added if desired? OF what
value is the fat in a fertilizer?
The ammonia, phosphoric acid
and potash in an ordinary grade of
cottonseed meal readily become
quickly available to plants. Cotton
seed meal is considered an excellent
carrier of nitrogen. You will see,
of course, that it is an unbalanced
plant food in it's natural form. There
fore, it is best to combine it with
other farms of commercial ferti-
lizers. A good thing to use for this
purpose is acid phosphate. Six hun
dred pounds of cottonseed meal of
the grade indicated, 200 pounds of
nitrate of soda or sulphate Of am
monia, and 1000 pounds of acid
phosphate will make you a high
grade formula well suited to the
needs of most farm and truck crops

priced lately that it has not been
used very extensively for fertilizing
purposes. Years ago. when there
was an abundance Of it, a great
deal of it was used in the produc-
ton of corn and cotton. If you wish
to use a formula containing more
potash than the formula, given
above, reduce the amount of phos-
phoric acid indicated to 1000 pounds,
and use 200 pounds OF kainit, Or
sulphate or muriate Of potash, ac-
cording to the percentage of the
available potash YOU desire to OBJ
tain in the formula. The fat is of
no value for plant food purposes. In
fact, it is rather detriment in the
soil. It furnishes. no plant food
which growing crops cannot already
obtain in sufficient quantity.
Protecting Corn From Weevil
Damage
w. C. S., Harrison, Ca,
writes: Please advise me how
to treat corn to keep out the
corn weevil.
Corn can be kept free OF weevils
by a comparatively simple pro
cedure. The first thing is to put it
in a relatively tight box or bin, de-
pending on the amount of grain to
be treated. Presumably, at this sea-
son of the year, you only have a
relatively small supply of corn.
Hence, it will be an easy matter to
put it into a container of the char
acter suggested. Having accom-
plished this, secure some carbon
bisulphide from the nearest drug
store. This material is not expen-
sive, and 1 think it is carried by all
druggists. A commercial grade OF
this material will answer every pur-
pose. When bought, it will be in a
liquid form, but if poured out in
shallow pans and placed on top OF
the grain, it quickly dissipates or
volatilizes into the air. This gas is
| heavier than air; hence, it win
penetrate into every part of the
container. 1t is not poisonous to
human beings. though if inhaled for
any considerable length of time it
will produce unpleasant symptoms.
1t is not dangerous, except that it
is inf1ammable. Hence, it should not
be handled in the presence of lights
1t is best on this account to keep
| it stored in an clubhouse. This gas
has a most peculiar and penetrating
Ddor. 1t will not injure the clothing
nor will it burn the hands The
effectiveness of the treatment de-
ponds on the thoroughness with
which the work is done. In n COM
pa~ltiveiy tight bin, one should use
two pounds of carbon bisulphide to
every one thousand feet to be treat
ed. Where the grain is confined in
Slated storage bins, it may be nee
essary to use as much A six pounds
of carbon bisulphide to every one
thousand cubic feet of space to be
treated. The bin to be treated
should be covered with heavy tar
paulin or cloth sacks and the
fumes confined therein as complete
ly as possible for a period of twelve
| to twenty-four hours. After the
| treatment has been completed, open
up the grain and expose it to the
air. A retreatment in two weeks
| should be made so as to be certain
to destroy any weevils which may
| escaped the first dosage.
