THE SOURCES OF NITROGEN

meal alone. Where high grades are de-
sired, and Il Is important 10 stimulate
the crop Immediately after termination
the combination OF some OF the forms Of
nitrogen mentioned above with cotton
seed meal. not only raises the standard
OF the fertilizer but provides, as already
Indicated, an ideal combination OF these
materials for supplying the needs OF a
crop throughout a long growing season
OF course, In purchasing nitrogen one
should be governed TO some extent by
the relative cost OF a pound of available
plant food. Attention should also be given
10 its relative availability and the con-
ditions under which IL can be utilized
with the least danger of loss through
teaching or Fermentation. On account of
the small amount OF vegetable matter
in the soils OF the southeastern states
cotton-seed meal is particularly service
able because Of the qualities already
enumerated which 1t possesses.
ESTIMATING CERTAIN FERTIL-
IzER VALUES.
H. Y, Columbia, S. c., writes: was
much interested in the table of fertilizer
formulas published recently, but do not
understand just how the values were
estimated. 1 assume that the yield is an
estimate II II could be assured, We
would have no difficulty In inducing our
tenants TO make the heavier application.
have bought this year, Thomas phos-
plate II 1-2 per cent, nitrate OF soda
is per cent; fish guano u per cent; mu-
rate Of potash 20 per cent Would be glad
to have you tell me in what proportion
to mix these ingredients for cotton on
lands of light loan with clay subsoil
which grow q good weed.
In making the calculation relative to
the cost OF fertilizers as used on the
cotton tests in our demonstration field.
MOO was allowed for a two-horse load
OF manure, $40 a ton for nitrate of soda,
s45 a ton for muriate OF potash, and SIS
for acid phosphate You will find that
these figures win enable you to determ-
inc the cost accurately of the fertilizer
used on each acre of land. You are mis-
taken in supposing that the yield on
these plats is estimated, as much OF
this cotton was grown on half-acre
pIats and some OF II on acre sections,
and 1t is an actual fact that two and
a third bales OF ginned cotton were Sc
cured from an acre of land on the col
lege farm last year. If the land is pre-
pared and cared for the same as the
land mentioned In these tests, you can
acre. You should bear In mind that this
same land two years ago would not pro-
duce more than a third of a bale per
acre. OF course il has been under the
supervision of competent men and not
left 10 the management of Indifferent and
careless labor.
BY mixing together 1000 pounds OF
Thomas phosphate, 200 pounds OF nitrate
OF soda, 400 pounds of fish scrap, and
400 pounds Of your rnuriate of potash mix
ture, you will secure a formula which
viii approximate 10 per cent of phos-
phorus. per cent of nitrogen, and 4 per
cent potash. This formula used at the
rate of -. pounds per acre should give
you good results though better proper
tionafe results win be secured from fer
tiIizer on lands containing a relatively
large amount OF vegetable matter. Under
the circumstances it would probably be
better for YOU TO put 800 to 400 pounds
Of this mixture under the drill row and
use 100 TO 80 pounds as a side appli-
cation several weeks after planting.
EVIDENCE OF USING MQLDY FOOD.
c. W. NJ, Haleyville, Ala, writes:
have a COW that is sick. She has spells
OF kicking and her eyes nearly burst
out OF her head. I also have a horse
that I can not fatten. He is lively, but
seems to have kidney trouble. Any in
formation as to what to do for these an
finals will be appreciated.
We are unable from the description OF
your cows trouble TO make a definite
diagnosis, but would suggest that you
examine your food materials closely for
mold. Do not feed any moldy feed.
In regard to the horse. feed carefully
on feed Of good quality. Water before
feeding. Use the following as directed;
Sodium sulphate. 2 pounds.
Sodium chloride, 1 pound
Sodium bicarbonate, IL pound.
Mix and give tablespoonful on the
feed three times a day.
THUMBS IN PIGS"
w. Y H, wetumpka, Ala, writes:
would like to know what to do for pigs
that have thumps. They begin a cough
and thumps follows. All the pigs that
take the disease lie. They are from
5 to weeks old.
From the description you give it is
evident that your pigs are affected with
Oh olera. This Is very fatal disease
of swine. an meicinal treatment oes
little or no goo. Tog cholera serum
is the only known preventive an cura-
tive agent. Consult your local veteri-
