icals that are to be mixed with enough
stable manure. earth or leaf mold to
make n ton. They viii cost $40 per ton
T.. o. b. Baltimore. freight a.5o. They
analyze, available phosphoric acid, IL per
cent or "A pounds; ammonia, per cent,
or SIS pounds; potash (actual K2O),
per cent. or 43.4 pounds.
Now. according to my calculation
will have In n ton of the fertilizer as IL
will be when mixed with the stable ma
nure a fertilizer that will have:
Phosphoric acid. 81 per cent
Ammonia. ...'. 80 per cen.
IotaSh....... .-....... I'd per cent
II this calculation Is not correct, please
state the exact amounts.
Now. is $40 fair price for such FER
tilizer? Would IL be better for me to
make n mixture of kainit, acid and meal?
.. can get nitrate of soda, 10 per cent
or 3SS. IS pounds of ammonia. at 500 per
ton: cotton meal. ~ per cent ammonia,
2i@ per cent phosphoric acid, 1ia per cent
potash. at $3.50 per ton.
I find that TO buy the same number Of
pounds of ammonia I'm the form of meal
that Is contained I'm ono ton of nitrate
world have to nav $685. more. VIII the
potash and phosphoric acid contained in
the cotton meal make tho difference in
price? Is nitrate the cheapest FORM IN
which To buy nitrogen? Does " take
the place of the meal as an all-round
armoui9te?
Answer IT Is not clear whether you
mean that The coo pounds Of chemicals
will cost SO. with freight added or that
n ton Of the chemicals will cost SO. You
say "They will cost so ton, f. q. h.
Baltimore. freight $50" Assuming that
you mean that the GO pouuds of chem
icaIs will cost SO. they will be cheap
enough If the ingredients are of approved
character as the terms OF the analysis

". ,,r,,,ro+;or Iaax,incy o1tt the little
plant food in the coarse material, is
correct excepting that the percentage OF
potash would be 2l7 instead of 23 per
cent As already stated, the price would
be reasonable and fair, but the fertilizer
would not he well balanced Tor some
crops, such as cotton and corn, contain
ing too little phosphoric acid for cotton
and too much potash for corn. You could
get n better balanced fertilizer OF acid,
l,ainit and cotton meal, say:
FOR COTTON.
Acid phosphate "a per cent? 1000 pounds
Cotton meal. e.. o.. e. 5000. 400 POUNDS
Niuriate of potash. . . 80. IS pounds
,or kainit, 800 pounds.)
FOR CORN.
Acid phosphate "a per cent? 1000 pounds
Cotton meal. 80. .... $500 l'-90 poun9s
Aluriate OF potash. ~ pouhuS
Tor kainit. l20 pounds)
The amount of muriate Cor kainiD may
be Increased II Sdih4s ptAits NNDN" go
or very old worn gray uplands.
. At $50 per ton OF nitrate OF SODA con-
tanning lG per cent nitrogen, the ammo
MIA would cost nearly 1913 cents per
pound Allowing cents per pound LOT
Tho nhosDhoric acid and Genus per
pound for the potash in cotton meal, the
value of these two elements In one ton
of meal would amount 10 $40, which
would leave S23.S0 as the cost OF the
40 nounds Of ammonia In one ton of
meal or nearly 15.9 cents per pound OF
ammonia which is too much. You,
therefore cannot afford 10 buy cotton
meal for use as q fertilizer at the cost
OF $3.50 per ton.
Al the prices you quote nitrate OF soda
IS a much cheaper source OF nitrogen
than cotton rreal But nitrate OF soda
does not wei take the place OF ie9S
N,,,i,.l,r,- avail. bIe form, such as cotton
meal dried blood, tankage, etc ~
should not be al applied at once, nor
any of it long before planting
