the phosphoric acid costs 5 cents per
pound. Kainit carries about 1875 per
cent. of potash, the fertilizing constit-
uent of value in this material. One ton
Of ~kainit would contain $50 pounds of
potash, which, at 1880 per ton, would
pound.
Cotton seed meal in this state must
contain not less than 711 per cent. am
monia, or $50 pounds in the ton. When
meal Of this grade sells for $25 per ton,
and the phosphoric acid in it is valued
at cents per pound, the potash at
5.4 cents (the price of these materials
in acid phosphate and kafnit), the am
monia would cost 1875 cents per pound.
On basis of this data:
One ton (2,0OO pounds) cotton seed
meal contains and is worth:
Ammonia, $50 1b@13.50c. ....... $20.25
Phosphoric acid, 56 1b@5c...... 2.SO
Potas, SO tb@5.4c............... 1.95
Fertilizing value one ton cotton
seed meal ,.................$2 5.OO
In the above calculation we have al
lowed 2.8 per cent. phosphoric acid, !
1.8 per cent. potash, in the meal. These
constituents would have a value of
$475, and the ammonia $20.25 one ton.
Allowing the same values for phos-
phoric acid and potash as given above,
when the meal sells for $26, the am
monia would be worth 14.2 cents per
pound and one ton (2,O00 pounds) cot
ton seed meal contains-and is worth
Ammonia, $50 & @14.2c.........$21.3o 80
Phosphoric acid, Sc 1b@5c...... 2.8O
Potash, Sc @5.4c.. 1.95
Fertilizing value one ton cotton
seed meal ................. .$1o:Vo
Using the same values for the three
fe-tilizing constituents as assigned
them above in cotton.seed meal, selling
for $25 per ton, it will give:
One ton 600 pounds) cotton seed
as containing and being worth as fol-
lows:
Ammonia, Is rb@13.5c..........$10.1S
Phosphoric acid, Is 1b@5c...... 1.30
Potash, "a b@5.4c 5.4c.............. 1.30
Fertilizing value one ton cotton
seed ................... $l2.73
When the ammonia in the seed is
valued at 14.2 cents per pound 1.-THE
price which is paid for it when meal is
sold at $26 per toni, one tom (2,OOO)
pounds) of seed would contain and be
worth

Phosphoric acid, 26tb @5c........ 1.S0

It is thus seen that cotton seed, |
pound for pound, have little more
than cne-half the fertilizing value OF
meal. When the meal is high-grade. !
containing eight or more per cent. OF !
ammonia, it has more than double the
fertilizing value Of the seed.
For seed, $13.25 per ton is about the
same as twenty cents per bushel, and
$12.73 corresponds to 1911 cents per
bushel.
It therefore follows that the farmer
who sells cotton seed at twenty cents
per bushel and buys meal at $26 per
ton is getting the fertilizing materials |
contained in the meal at the same |
price as that he carried to the mill in |
the seed. In like manner 1871 cents
per bushel for seed corresponds very
nearly in fertilizing value to $25 per
ton for meal.
When seed are sold for 1871 cents per |
bushel and meal bought at $26 per ton,
the farmer actually gives the oil man
over fifty cents more in fertilizing |
value in the seed than he gets back In
the meal. With seed at sixteen cents
per bushel, the difference is even
greater and no farmer can afford to
sell seed at these prices and buy meal |
even at $25 per ton.
Considerable quantities Of seed are
exchanged for meal at the oil mills, the
rate of exchange being usually 1,100 to
400 pounds of meal for ton of seed.
It has been seen from the above that |
the one ton Of cotton seed contains
$12.73 worth Of ammonia, phosphoric
acid and potash on basis Of what is
paid for these three constituents in
acid phosphate at $14, kaiait at $3.50,
and cotton seed meal at SIS, per ton
each.
What quantity Of meal will contain
these cons tituents to the same value
as one ton of cotton seed?
One thousand and nineteen pounds Of
meal, containing seven and half per
cent. ammonia, will contain and be
Ammonia, 76.4 lb q 1850. $40 80
Phosphoric acid, 23.5 1b q &c.,. AZ
Potash, 1873 lb @ 5.4c.......... 80
Fertilizing value of 1.019
pounds of cotton seed meal. 1918
which is the same as the fertilizing
value of one ton Of seed.
Whatever the farmer gets above this
goes to pay him for the labor and ex-
pense Of hauling and handling the seed
and meal In making the exchange.
These are items we'll worth considera-
lion and enough meal above 1913
pounds should be obtained in the ex-
change tc make It worth the while of
The farmer to make rne exchange.
The Gilman gets about forty-flve
gallons of oil from a ton OF seed, which
varies in price from fifteen to thirty
cents or more per gallon. As Its SELL
ng price is not very high this season. I
