SING POTASH UNDER CORN AND

| SING POTASH UNDER CORN AND
COTTON.
ID. s., Smyrna Ca, writes: l have just
| read article which states that potash
| does not pay under oats and corn. What
| would you recommend me to use under
| these crops?
The results We have obtained for the
asst five years would indicate that tae
edition OF potash to q fertilizer will
-ot pay under corn in practically all the
| .orthern half of the state, especially on
| red land In many instances we have
| ,btained no increase whatever for the
addition of potash, and in practically no
| case has the increase been sufficient to
pay for the potash even at normal
prices
We are using the following mixture Of
| fertilizer on our corn which is being
planted at the present time: Acid phos-
phate 1,4O3 pounds cotton seed meal.
267 pounds and nitrate of soda $50
pounds. This gives approximately J
per cent of ammonia from cotton seed
meal and ger cent of ammonia
from nitrate of soda. 1t would make
/ the fertilizer cost slightly more, but it
would improve the quality to put in rela-
| lively more cotton seed meal and less MI
trate of soda. We would advise the APP
] plication of 400 to 500 pounds per acre
of this mixture, depending on the quality
of the-lan
! A top dressing of nitrate of soda at
the rate of about rs pounds per acre
will be very beneficial for your oats.
MANAGEMENT OF ALFALFA PATCH.
r. t. D., Fayetteville, Ga, writes:
planted acre of alfalfa year ago last
! September, and have very poor stand.
What would you advise me to do at this
timer Would IL do to rcSeed it,
The probabilities are that it will pay
you better to pillow your alfalfa up and
reseed again next September. You do
not state now the land was handled pre-
viously, but unless you put on as nue.,
as four or five tons of ground lime per
acre, I void advise you to refine at
the rate of not less than two tons per
acre Immediately. Apply half of thc
lime before the land is turned and the
cIner half afterwards. A top dressins
OF stable manure would be of great heln
provided il can be cured at this time
AS soon as the land is sufficiently warm
ed up for early pea planting, SOW about
two bushels per acre of any good vining
variety This will serve the two-fold
purpose of improving the condition o
! tire land. and at the same time smothe~
out any weed pests. The peas can elite"
| DE cut off or turned under early in Au-
gust The land should then be worked
to a firm seed bed and the alfalfa reseed
ed in September.
PRESERVING SEED WHEAT FROM
wEEVIL.
l. L. s., warrenton,. Ca, writes We 81,
are obliged to carry over several bushels
of blue stem wheat and the price is so
high we would like TO preserve this seed 10
suppl ment our planting next fall. How is
best to preserve this wheat safe from wee
wills and other verminl
About the only thing that would dam
age your wheat would be wesvils. AM
you can protect the grain against thes.
| by the use of carbon bisulphide.
| should be used at the rate of one pount
TO one ton Of grain, or I'm empty rooms
the pound to every 200 cubic feet. The
| tighter the receptacle i'm which the whea
| is placed the less carbon bisulphide
needed to effect the destruction of the
weevils. Several treatments during the
year may be Necessary Place the bisul-
phide in small pans on top of the grain,
and as it is heavier than air it sinks
rapidly down through the grain. The
carbon bisulphide is very infiammable
no light should be used i'm its vicinity.
VARIETIES OF CORN FOR SILAGE
have some medium graie upland which
l wish 10 plant in coch and sorghum TO
fill silO. What variety OF corn would
you reco mmend, and would you advise using
sarghum also?
We have obtained the most satisfac-
tory results on the college farm from the
use of Cookies Prolific corn for silage
purposes planted in alternate rows with
the old fashioned Red Head sorghum.
1 I'll, iags
growth and stands up better than the
otner varieties we have tried This
year we are trying a mixture Of Red
Head sorghum and white Kafir corn for
our silage. The reason we are substi-
tuting the kafir corn in this trials is that
| it is so much better drought resistant
I than the regular corn. I suggest THAI
you try at least a small area of this
mixture. We use 3 pounds of sorghum
seed and one pound of kafir corn. The
seed is well mixed together and planted
at the same time.
| HARDWOOD ASHES AS A SOURCE
OF POTASH.
~ L. S.. Gainesville, Ca, writes: We
have bought several tons of hardwood un-
leachced ashes to use as fertilizer this year.
What would yOu advise to mix with themf
We are expecting to mix with cotton seed
meal. What proportion would you advise,
and would You duNice tue duuAtlou VI
thing elseg
The ANALYSIS of hardwood ashes
varies materially. Provided they are
! from hardwood and unleached they
should carry from 6 to s per cent Of
potash. Pine wood ashes unleached will
not run over to 1 per cent. You do
not mention the crops under which you
intend TO use these ashes, but in the
vicinity of Gainesville and on red land,
1 doubt whether you will get any APP
~reoiable increase for the use of potash
under corn. I should make a more lib
eral use of ashes under cotton. Fur
thermore the ashes ordinarily carry
about so per cent of lime which would
mean that in order to get complete
fertilizer Analysing as much as per
cent of potash, you would have to use
around 500 pounds of ashes. This would
give 800 pounds of lime and it would
have an appreciable effect on rendering
insOluble the phosphorus in acid phos-
phate l would therefore advise you
to apply the ashes separately without
mixing them i'm the complete fertilizer.
