pounds of nitrate of soda as top dres

season. This would maintain the nitrogen
at the percentage indicated, and would
increase the percentage of acid and pot
ash II being desirable that you use more
potash on sandy land.
Fhe original fertilizer suggested will an

II you desire make a compost as follows:
Mix together 1,400 pounds of farmyard
manure or well-rotted compost, 200 pounds
of cotton seed meal 300 pounds of acid
phosphate and 100 pounds of muriate of
potash. This mixture will contain about
22.4 pounds of nitrogen, 579 pounds of
phosphoric acid and GA pounds of potash.
A ton of 1t would be equal in fertilizing
value to at least 1000 pounds of S-2-2
fertilizer. You should use one ton per
acre. You will find this very good fer
tilizer for either corn or cotton on sandy
land such as you describe yours to be,
POTASH AS A PREVENTIVE OF
RUST.
H. A. G., Hawkinsville, Ga, writes:
l have a small place in south Georgia
which 1 bought two years ago. About
half of it is a sandy gray top soil with
deep clay subsoil, and the other half
is a mulatto red top soil with a deep
clay subsoil. big portion of the cotton
rusts, it does not make sufficient weed,
and it does not fruit as 1t should. Please
give me a formula for mixing fertilizer
for this land Which is best to make
weed, tankage or cotton seed meal?
One of the surest methods of increas-
ing the fertility of your land would be
to divide 1T up so you can put it under
systematic rotation. For instance,
part of IL might be seeded to oats in the
fall to be followed by peas for hay in
the summer. The second part might be
planted to corn and the third part to
cotton. Next year bring the oats after
the corn, and the next year corn after
cotton. This will enable you to diversity
your crops, and this method of cropping
will prove less exhausting to your land
than the single crop system which you
are now evidently using. 1t is quite evil
dent from what you say that your land
needs to be heavily fortified with high
grade material We think you should
use per cent of nitrogen, 10 per cent of
phosphoric acid and 5 to s per cent of
potash.
The rusting of cotton is due to an inn
paired physiological condition of the
plant, and this condition is attributed to
the poverty of the soil in some element
| that is essential for crop production.
Since the application of potash seems to
correct this trouble to some extent, it
should be used quite literally where cot
ton sheds it's foliage. The fact that you
do not get enough stalk is an evidence
that the land is deficient in vegetable
matter and nitrogen, and shy fruiting
will be helped by the liberal use of phos-
phoric acid. A mixture that will contain
| the percentages of plant food suggested
may be prepared as follows:
Mix together 1000 pounds of high grade
acid phosphate, 800 pounds of tankage
containing per cent of nitrogen and IL
per cent of phosphoric acid, and 200
pounds of muriate of potash. You may
purchase the materials using only those
of the highest grade and mix for your
! self, or probably you can find some man
ufacturer who will prepare this formula
| for you upon request. 1 would be guided
| in using cotton seed meal or tankage as
fertilizer for cotton altogether by the
relative cost of nitrogen.
