100 parts of aeh Of cotton seed contain
Phosphate OF lime, 1902; phosphate of DO
tassa, 1857; chlorides of sodium and potas-
sium, 3 81; sulphates, 5.65; corbonates OF
lime and magnesis, 2.S5.
NUTRITIVE AND AGRICULTURAL VALUE
OF COTTON SEED CAKE.
Each ton of decorticated cotton seed cake
will yield 375 pounds of oil, TO pounds OF
albuminous compounds (lesh producing
principles), 532 pounds of sugar, starch,
gum and mucilage (hest producing agents),
and $50 pounds OF phosphates, chlorides
and sulphates. Total nutritive elements in
one ton, l,S27 pounds. 1t is fair TO esti.
mate the value of this food, rich in oil and
Litrogenous matters and phosphates, at two
cents per pound. This estimate is uncer,
rather than above the nutritiVe value in the
feeding and fsttening of stock. NutritiYe
value of one ton of decorticated cotton seed
cake, S36.74.
In computing the agricultural value, it
should be observed that each ton is capable
Of yielding 100 pounds of nitrogen, which
alone may be estimated % possessing an
agricultural value of from $50 to $32, and
the phosphates Of lime and pot sh, possess
an agricultural value of about 81. The ag-
ricultural value does not differ therefore,
materially from the nutritiye value.
RELATIVE VALUE OF COTTON SEED CAKE
PRACTICAL CONCLUSIONS.
l. The proportion of oil is higher than in
the best linseed cake, which rarely contains
more than from 10 to Is per cent. of this
ingredient, which is so valuable for supply
ing fat to animals.
2. Cotton SEED cake contains a very high
percentage of nitrosenizsd, flesh pro 4ucing
matter; and this renders it especially valu-
able for young stock and dairy COWS.
3. The ash of cotton seed cake is rich in
bone material, thus each ton is capable of
yielding sixty pounds of phosphate of lime
and seventy pounds Of phosphate of po-
tass2.
4. At this late day, no planter in the
Southern States is grorant of the fact that
cotton seed will compare favorably with the
hest commercial fertilizers.
8. That cotton seed cake is potent fer
tilizer, is evident, not only from its ac-
knowledged beneficial effects, when applied
10 growing crops, bet also from the follow
ing established facts:
Plants require large prppotion of veget-
able and animal matter, to afford o supply
Of carborn, in the shape Of carbonic acid,
and of nitrogen in the form ammonia, both
of which are evolved during the decompo-
sitlon of organic substances. Cotton seed
cake is most valuable to grain crJps be-
cause the seed of plants, is in sill instances
the most highly szotized portion, and all
plants require a supply of nitrogen to per-
feet their seed; which nitrogen cotton seed
can furnish in large proportion.
Cotton seed cake is quick in its effects,
because fermentation and putrefac,ion take
place almost Immediately after its applca-
ton to the growing plants, and carbonic
acid and Ammonia are supplied to the roots
of plants in large proportions. The plant
IN its infancy feeds upon and is developed
out of the matter of the seed, but after it
has developed certain tibres it begins to take
up nOurishment from the soil, while the
green leaf or shoots, which il has
sent upwards, extracts carbonic scid
from the air. If the roots
find no food near, they increase in number
and length and spread over a | rye surface,
and in poor soils, from this cau.e, plants
have an immense number of fbsIs, roots,
and poor stunted stem; these numerous
roots having been formed at the expense of
matters which should have assisted in the
growth Of the stem. Cotton seed cake,
from its rapid decomposition, aud the COM
paratiyely large amount OfcarbODic acid and
ammonia evolved, supplies the young plants
with the best liquids End gaseous food at
the most critical period, and onsequently
enables the plants to develop stouter
stems and more perfect and numer-
Gus leaves; for it appears to be well
that the sooner the
plat escapes from the state of transi-
ton in which it derives its food from the
seed SIS well as from the soil and Amos
phere, the sooner will its organs for extract
ing its food from the air and soil be devel-
oped, aud the more vigorous viii be their
growth.
6. One ton of cotton seed cake equals in
agricultural value from II to IS tons of
farm-yard manure.
Z, The great advantage resulting from
he application Of cotton seed as a manure
Tor corn, is referable to the high percentage
IF phosphoric acid and potash in corn. One
thousand pounds Of cotton seed are capa-
Die of yielding the necessary potash for
about 1000 pounds of corn, and phosphoric
scid for 1900 pounds of the same grain.
