Amount of Fertilizer In an Acre of Cotton.
QUESTION. How much fertilizer may
be profitably used in an acre of cotton
/ have been trying different amounts,
but so far my experiments are rather
contradictory and disappointing.
ANSWER. The amount of CONNER
cial fertilizer which may be used on an
acre of cotton varies so widely with the
quality and condition of the soil, the
seasons, previous crops grown, and
many other circumstances, that no set
rule can be laid down. Generally
speaking, if the land has been brought
to very high state of cultivation very
heavy appl cations may be made, but
for ordinary Georgia soils in good con-
dition, that is, which have been care
fully cropped and improved and not al
lowed to become hard or destitute of
humus, an application of about 700
pounds per acre has been found most
profitable. When this quantity is used
it is advisable to apply half in the drill
and we'll mixed with the soil at plant.

bulletin from the Georgia Experiment
Station says "It has been shown that
$500 worth of well balanced fertilizer
may be expected to increase the yield
of seed cotton on one acre / 200 pounds.
But such results can only be attained
by concentrating the fertilizer on the
best land, not by scattering it at the
rate of 100 or 200 pounds per acre over
a large, worn out plantation. The mis-
take should not be made of applying
large amounts of concentrated fertil-
izers on thin, worn out land. The larger
the applicat on the more important it
is that the land be in the best possible
condition. State Agricultural Depart.

The Proper Proportions of the Different
Elements In Fertilizer For Cotton.
QUESTION. Please give me your views
as to the best proportions in which to
combine phosphoric acid, potash and
nitrogen to successfully fertilize a cot
ton crop.
ANswER.-In fertilizing a cotton crop
phosphoric acid is relatively the most
important element and controls the &C.
ton of the other two. Its presence is
very important to the development of
perfect bolls. and while it may be used
alone with some beneficial results, 1t
is much more effective when combined
with the other two. Neither nitrogen
nor potash, when applied alone, produce
any appreciable increase in the yield,
and these only do their best work when
combined with each other and with
phosphoric acid, which latter exercises
the deciding influence as to the quantity
of each, which can be profitably used.
That is, in making up a formula for
cotton, the amount of phosphoric acid
should determine the amounts of the
other two. Potash and nitrogen are
generally used in the same proportions.
and the amount of phosphoric acid
should be from pa to 8 times as large.
Thus: Potash, /; nitrogen, /; phos.
phoric acid, from 234 to 3, would be
about the proportion for general use.
and these proportions we would get

Is 1t Best For Cotton to Apply Fertilizer
in the Drill or broadcast?
QUESTION: have decided to make
heavy application of commercial ferti-
lizer to my cotton crop. Would Won ad.
wise me to apply in the drill or broad.
cast? The land is in moderately good
condition. Some of it was in corn last
year, some in grain and some in peas.
ANswER.-Our experience has been
that when large amounts of fertilizer
are used it is not advisable to apply in a
single drill. Either two separate appli.
cations should be made, one in the seed
drill at planting time and well mixed
with the soil and the other in the first
