The only way that this oil has been sue
cessfully applied TO plants has been In
the form of an emulsion, and even then,
If the emulsion is too strong, the plants
are apt to be injured. The success at
terdant upon the use of kerosene emul-
SIGN depends entirely upon the kind of
emulsion made, and applied.
The following is Cooks formula for
kerosene emulsion; we have used this at
the college with good success, particular
ly against plant lice on the apples

water is best, but the addition OF oo-

soap is shaved in thin slices into the
water, which is heated to facilitate the
dissolving of the soap, if the water Is
not too hot. the hand may be used TO
mash the soap, and thus hurry the dis

The fertilizer formula best suited Tor
corn and cotton on land such as you
describe will depend on NUMBER Oh con
ditions. First of ALL, you do not sla'e
whether YOU secured a sufhclent sro"t"
IF stalk to insure a good yield In your
section of the state. If you do secure
suficient amount of weed at the present
time, then the use of large amount
of nitrogen in the fertilizer is unneces-
sarv. For sandy land, however, the use
of phosphoric acid and potash should pc
rather liberal, though such large amount
need not be used as where the land has
a sandy subsoil. The clay subsou IN
dicates a fairly strong soil naturally, and
one that will hold plant food with corr
siderable tenacity. This type or SOIL VIII
also not be nearly so leachy as a deep
sandy soil.
The greatest need OF all our Georgia
soil is vegetable matter. To this END you
should endeavor to use some compost
under the drill row for both corn ana
cotton. There is nothing better than
farmvard manure. The waste about the
farm, the leaves from the wood lot, and
much other material may be composted
with the lot manure and fine material
obtained for enriching the land. 1t is de-
sirable to use at least two tons per acre
under the drill row, but one is much
better than none at all. Where you can
use compost, probably per cent of nj
trogen, 10 per cent of phosphoric acid,
and to per cent of potash will De
about the right kind of fertilizer Tor
your land.
Corn being a grosser feed plant than
cotton and requiring more nitrogen for
its development probably per cent OF
this element should be used under II.
The ACCESSIBILITY of top dressing with nj
trate of soda will depend on the devel-
opment made during the growing season.
If the rains are well distributed and you
get a strong. healthy plant, top-dressing
will probably be unnece ssary, but If tho
crop is backward and not of a good
color, then at least 100 to $50 pounds of
nitrate of soda per acre should be used
as a top dressing This should be applied
to the cotton from the 1st to 18th of June.
