is sticky red land and has been planted
to cotton continuously for 1--WE years, We,
the soil is fairly good even now. Do
you think a mixture containing 200
pounds of S-2-2 (tankage) and 100 pounds
of nitrate of soda to the acre a proper
fertilizer applied about May 2O7
You can not effectively protect your
corn from the worm in question by i'm
mersing IL in bluestone before planting.
This pest is particularly bad on low,
moist bottoms and the best means Of
lighting il Is to rotate crops. II does
not attack cotton or buckwheat or beans,
for instance, and IL corn is not grown
on the land every year in succession the
worms will not multiply a. rapidly ana
the damage will not be as great. For
beans arsenate of lead has been used
to some extent as a spray for the control
of this pest, but no means has been
found for protecting corn which Is suffi-
GENTLY cheap to justify its use up to
the present time. 1t is suggested where
the worm is bad to plant the corn In
hills. putting several grains in each
place. OF course hand thinning after
the plants develop to some extent will
have to be resorted to and this Is a
laborious undertaking.
An application of 200 pounds OF 2-s-s
fertilizer to sticky red land intended for
corn would hardly be regarded as lib
eral amount to use. Two to three times
this amount would be better. Even
then tho proportion of potash and nitro
gen is low for such gross feeding crop
as corn. 1t is true that the nitrate OF
soda used as a top dressing will tend
to balance up these materials ana IL
should prove of great beneht to the crop
ia oT1D "A SUGGEST.
Personally we would prefer to put the
$50 mixture down as soon as possible.
Where il can not be put under the drill
row, il may be applied alongside the
same with a fertilizer distributor or
sown broadcast over the land and worked
in at the first cultivation. Since phos-
pheric acid and potash do not become as
readily available in the soil as the nitro
gcnous compounds. it is best to put them
In rather early so as to give them rlme
to dissolve and be assimilated by the
plants. ..-
POTASH AS A SPECIFIC FOR COTTON
RUST.
r. L. j., Oakpark. Ga, writes: 1 have
a niece of land on which cotton blights
or rusts badly. I have some S-2-2 guano
and some l6 per cent acid and IL per
cent kainit that l am thinking of mixing
as follows: Two sacks OF acid and one
each of the guano and kainit. What
would this analyze, and will II be better
for cotton than the 1922 guano?
The mixture which you propose to
make would approximate S25 pounds in
weight, and would contain about four
pounds of nitrogen, so pounds of phos-
phoric acid and 80 pounds of potash. You
will see that II would not be at all bal
anced as a fertilizer for cotton. A 2-S-2
is certainly low in potash and nitrogen
for land where cotton rusts badly, and
YOUR proposal to use a sack of kainit
with each 200 pounds OF the 2-S-z Is all
right You might cut down the acid
phosphate to one sack with good adVan-
tage. You should then arrange to top
dress your land with nitrate OF soda at
The rate OF 100 to $50 pounds per acre
about the middle of June, II is possible
that your land may produce enough weed
already, but if so. ii is the exception and
not the rule, and you can hardly ex-
pect to secure a large yield of cotton
unless the soil is extraordinarily rich
where you apply not more than four
pounds of nitrogen per acre. 1t is proper
to emphasize the use of potash on land
that rusts badly, for 1t is among the best
specifics for this trouble which has yet
been found. You should remember also
that the rusting of cotton may be due 70
lack of drainage or vegetable matter.
Begin this year, therefore, to plan a ro-
tation which will enable you to increase
the supply Of humus through turning un-
der green crops or by preparing composts
