COTTONSEED MEAL,
Contains All Fertilizing Elements
Best Practice Is to Use as
Feed and Return Manure to
Soil.

Al the present time. when potash
in the form OF salts is practically nm
obtainable and when both nitrogen
and acid phosphate have advenced
IN price because Of the use of nitrates
and sulphric acid for munition pur-
poses, cottonseed meal, which carries
all three OF the fertilizing elements
becomes OF great Importance. In
recent years immense quantities OF
TINS material have gone into fertili-
zers, approximately 100000 tons
having been so used in 1913.

tions its potash content is highly i'm

determining the price at which the
material is sold.
In practice. cottonseed meal should

Most OF the formulas heretofore pub-
llshed have advocated various nro-
portions or acid phosphate and mu
rate OF potash in combination with
cottonseed meal. Muriate OF potash
is to all intents and purposes nm
obtainable this year and must be-
omitted from present consideration
III 1000 pounds OF cottonseed meal
ana 1000 pounds OF acid phosphate
are mixed. however, a ton OF material
results which contains about $50
pounds OF phosphate acid. 65 pounds
or nitrogen, and 20 pounds OF potash.
Ih1s is about per cent phosphoric
acid, 1925 per cent nitrogen. and !
per cent potash. and makes a very
satisfactory mixture for many soils
where field crops are to be grown.
For trucking and gardening, present
practice demands a higher content
OF potash. and the mixture NAV he

unbleached wood ashes il obtainable
Nitrogen in cottonseed meal is not
so quickly available as when applied
In the form OF nitrate. but on the
other hand. is not so likely to be
leached out in times OF heavy rain
fall. In light sandy soils where
teaching is rapid the use OF organic
material such as cottonseed meal is
to be preferred in supplying the
necessary nitrogen. Decay of the
organic material liberates the nitro
gen gradually and there is much less
danger of loss than is the case when
soluble salts, like Chilean nitrate
are used.
Most OF the mineral ingredients in
cottonseed meal are recovered in the
manure If the material is used rs a
