that phosphoric acid and potash are not
being supplied in large enough amounts.
Soils of this character may also some
times be deficient in lime. We would sug-
gest therefore, that you use under your
cotton about a 1-10-4 fertilizer at the rate
of at least 500 pounds per acre, and there
is no objection to putting Il all under the
drill row at the time of planting, though
if you prefer, you may put 800 pounds
under the seed and use 2uc pounds as
side application about June /. A good
fertilizer for corn would be S-110-4. Corn
needs considerably more nitrogen than
Gotten because ii is a grosser feeding
plant the season may have had some
thing TO do with the poor yield secured
from your corn last year. We had
somewhat similar experience on one piece
of lane which we have teason to believe
was is very good condition. However, the
corn was not gotten IN Just at the right
time and the crop never Seemed TO grow
off righ.. We would work this land thor
oughly and carefully and apply some veg
etable matter to it If possible. Two tons
of compost under the drill row will an
swer fairly well. Then use a S-10-4 fer
1:szer as suggested at the rate of 500
pounds per acre. This will supply suf-
ficient amount of plant food to insure d
good c-op of corn, provided seasonal con-
ditions are right and good strain of corn
s used There will be off crops and Oft
seasons we know. There are so many
conditions which enter in and affect the
crop that it is impossible to control all
Of them, but the thorough preparation or
the soil and a plentiful supply of plant
food win do more to insure our reaping
a good ciop than anything else.
B. p s., Iva. S. c., writes: Will nj
trate of soda pay as well mixed with
guano as it does used separately? Ii
so, how should it be mixed for cotton
per acre? How much should be used
per acre where the land makes good
weed, and 1000 pounds to the acre?
limited amount OF nitrate of soda
may be mixed in a complete fertilizer.
For instance. 100 to 200 pounds may be
used with 400 TO 900 pounds of cotton seed
meal to supply the nitrogen needed in a
high-grade guano. 1t would not. in our
judgment, be good practice. however, 10
put more than 200 pounds of nitrate in a
complete fertilizer where it is contem-
plated distributing this material in the
ground at or before the time of plant
a1nR corn ana cotton. NneIt II Is sucSli a
BILE to secure a mixture containing a high
er per cent of nitrogen than this, 1t would
be better to reserve the balance of the
nitrate and apply it as top dressing.
Top dressings may be made twice during
the season for such crops as corn and
cotton. Where two applications are
made. 100 pounds of nitrate of soda may
be used each time; where a single appli-
cation is made, $50 pounds would bly,
be the best amount to use. The objec-
ton to putting nitrate in the soil is due
to the fact that the nitrogen contained
therein is in a form Immediately avail
able to plants. When we put cotton seed
meal, for instance, into the ground, the
nitrogen must first be transformed into
ammonia and then into nitrates, and it
takes some time for this transformation
% take place and as the plants are grow
ing all the time, they are prepared to take
up the nitrogen as fast as it becomes
available. On the other hand, if nitrate
is put into the ground before the crop
begins TO develop, some of it may be
