supply a considerable quantity of nitro
gen, though a rather low amount Of
phosphorus and potash. but you have
attempted to provide this deficiency by
the use OF the 500 pounds Of the 10-4
bone and potash formula Four hun
dred pounds OF an S-3-3 guano will
answer very well, though in our juds-
ment there Is somewhat OF a deficiency
OF potash likely TO exist in your SOIL
at best, and we think you have not
used quite enough OF this material In
proportion TO the amount OF nitro
gen and phosphorus you have provided
On your system Of fertilization. If you
decide TO use a side application, you
might make the potash unusually high
and the side application had best be
nut on at relatively early date. IL
might be that you viii ind an applica-
ton OF 100 pounds of nitrate OF soda
benencial on this crop. You can tell
better about this as the season advan-

SUGGESTIONS ON BERMUDA ONION
CULTURE.

planted So quarts about the frst Of last
December Stable manure had been
broadcasted over the land the previous
summer. The manure was piowed in
deeply. Before planting out the sets L
ran or rows is inches apart and put
in 500 pounds of onion fertilizer, but
1 am afraid that all the rains we have
had have washed the fertilizer in the
direction Of China, and 1 wish to know
IL you think cotton seed meal would
do well IL applied at this time?
Your experiments in the cultivation
of Bermuda onions in your section of
the state are very interesting. and 1t
is TO be hoped that you will give us
full information concerning your final
results with this crop when you have
harvested IL. We believe you will md
applications Of nitrate OF soda as top
dressings much more satisfactory than
cotton seed meal for a crop requiring
rapid forcing and quick development
such as onions. OF course, cotton seed
meal could have been used to good adj
vantage as a complete fertilizer under
the drill row at the time of planting
the onions last fall. What you need
now, however, is something that be-
comes almost Immediately available for
the quick development of the tubers, and
there is nothing in our judgment which
you can use that will give better results
than nitrate of soda. Apply it at the
rate OF 100 to $50 pounds per acre,
making the application Immediately and
putting it on top Of the ground along
side the drill row, but not In contact
with the onions OF the tops thereon.
Put II on after a rain rather than be-
fore. Give frequent cultivation Of the
crop. We believe you will find a sec
ond application Of nitrate advisable.
This fertilizer has been used on onions
in applications of rs to 100 pounds
every ten days for a period of four
20 six weeks with profit. In our judg-
ment you will find $50 pounds the maxi
mum amount TO use at single applica-
ton
PREPARING A 1922 FORMULA.
W. NJ. A, Homer. Ca. writes: Please
tell in what proportion to mix the fol-
lowing ingredients to make 1922 fer
tilIzer: 16 per cent acid phosphate, is
per cent nitrate of soda, and As per
cent muriate of potash.
II you mix together 1880 pounds Of
16 per cent acid phosphate. ESQ pounds
OF nitrate Of soda and so pounds of
muriate Of potash, you will secure a
formula which analyses approximately
10 per cent OF phosphoric acid 2 per
cent Of nitrogen, and per cent of
potash. The total weight of this mix
ture would only be 1850 pounds, and
you would find it necessary to increase
the weight to 1000 pounds through the
addition OF leaf mold or rich earth. or
IL You desire 10 use the equivalent
amount of fertilizer contained in 500
pounds Of a ton mixture, divide the 1850
pounds by four. and apply this amount
to each acre. We think you will find
a formula such as you have suggested
low In nitrogen and potash for your
soils. especially for crops such as corn
and cotton. In our experience to 4
per cent OF potash has been found de-
sirable for these crops on all soils ex-
cept the very heavy red clays exist
ing in some sections OF north Georgia,
and the use Of TO per cent Of nj
trogen is justified according to our
experience. OF course, IL the farmer is
in position TO use vegetable matter de-
rived from compost or yard manure,
and thus save the cost involved in the
purchase OF such a large amount of
commercial nitrogen. IL is greatly to
his advantage. but If he has no ade-
