MERITS OF DIFFERENT FERTI-
LIZER FORMULAS.
A ID. =. Commerce, Ga, writes: Please
give Us the relative value of 1920 fertilizer
ammOniatcd with cotton seed meal, Gnd a
fertilizer made 10y mixing one-third standard
grade cotton seed meal and two-thirds 10
per cent acid phosphate. | would like 10
know the relative difference in dollars
say the 1920 to be worth $22.OO per ton,
what would the mixture of one-third IA
per cent ammonia cotton seed meal ana
t"o-thirds lG per cent phosphate BE worth:
mixture of 1-3 standard cotton
seed meal and 2-3 of 16 per cent acid
phosphate would contain approximate
ly 25006 pounds of phosphoric acid
per ton, 41.22 pounds of nitrogen and
1884 pounds of potash. These figures
were obtained on the presumption that
standard cotton seed meal contains not
only rs per cent of ammonia, but 20
per cent phosphoric acid and 1.9 per
cent potash If we allow organic nj
trogen value of 20 cents, available
phosphoric acid a value of cents and
available potash a value of 20 cents,
a ton of cotton seed meal of the above
mentioned grade would be worth 1851
for fertilizing purposes.
1t would probably be fairer at pres
ent prices to give phosphoric acid a
value of cents and potash in COM
mercial form, a value of so cents. On
the basis indicated, however, ton OF
mixture consisting Of 1-3 standard
cotton seed meal and 2-3 16 per cent
acid phosphate would be worth at least
S23.07 irrespective of any cost of mix
ing or bagging. $500 per ton would
thus be a very reasonable value to place
on fertilizer of this character.
COMPANION PLANT FOOD FOR
USE WITH YARD MANURE.
c. A. D., CuIberson, N. c.. writes: l
have an acre of upland mostly clay soil,
that have broadcasted with stable MANURE
this past winter. Please advise me the
best and also the amount of fertilizer
should on this and how to use for
best results.
1t is good practice, of course, to
broadcast yard manure on clay soil and
then work it into the surface by cross
discing. The amount OF supplemental
fertilizer to use on this land will de-
pend much on the quantity of barnyard
manure applied to it. AS you do not in
dictate either the amount of manure
available or the character of crop you
desire to plant on the soil, it is a diff
cult matter to advise you satisfactorily
as to the best method of procedure.
Presenting that you desire to plant
corn on this land, we would advise that
you use not less than 500 pounds of a
formula containing 3 per cent nitrogen,
9 per cent phosphoric acid and as much
potash as practicable. You can secure
the nitrogen from any source which will
furnish it at the cheapest price. Several
materials could also be used as sources
Of phosphoric acid. Possibly you will
find acid phosphate as satisfactory as
anything you can use, however. Cotton
seed meal also can be combined with
this material to advantage. Equal parts
OF the above mixture should prove sat-
isfactory. Put at least 800 pounds of
the fertilizer under the drill when the
crop is planted and use 200 pounds as a
side application.
FACTS ABOUT VELVET BEANS.
L. II. c., Vienna, Ca, writes / would
like information concerning the planting Of
velvet beans. Do you think it would be
well to plant the beans in the drill at the
time of planting of corn? viii 1t cut off
the yield of corn? l have been told by
some that ii will increase the yield OF
corn In comparison, which do you think
the most valuable a feed, velvet bean
meal corn?
There is no objection from our point
of view to planting velvet beans in
corn. We do not think this crop will
seriously initiate against the develop
ment of the corn crop. We have planted
the beans in the drills, alongside of the
corn and in the middles. We believe
that where corn is planted in five-toot
rows and the beans planted in the mid
dies that the beans made a little more
vigorous growth than where they are
planted alongside of the corn. There is
