You do not state how much nitrogen
and phospnoric acid the tankage you
used contains. We nave been assured,
however, that it contains per cent of
nitrogen and IL per cent of phosphoric
acid. In other words, that 1T is high
grade material. on this basis the mix
ture you propose to make would con-
tain about SO pounds of nitrogen per ton,
24o pounds or phosphoric acid and 1926
pounds Of potash. The percentage COM
position would be rs per cent Of avail
able nitrogen, 1872 per cent of Available
phosphorfc acid, and CO per cent Of
available potash.
On land where cotton makes plenty of
weed, this fertilizer will answer very
we'll, but If you do not get enough stalk
to suit you, we would suggest that you
use a little more nitrogen. This might
be supplied by nitrate or soda used "a
the form of a top dressing some time
during the month Of June. Your mix
ture certainly contains a high per cent
of phosphoric acid and potash, and
mould supply the needs of a cotton crop
on land such as you describe in suffici-
ent amount If usld at the rate Of 400
to 500 pounds per acre. If your land
is gravelly and inclined to be leachy on
that account. we would suggest that you
make an unusual effort to secure some
compost and leaves or yard manure or
any other organic substance to put OIL
the land as soon as possible because
there is a probability that part of the
plant food applied will be leached away
and never be OF any service to the plant.
PREPARING A HIGH-GRADE FOR
MULA.
w w. Nj. Moultrie. Ca. writes: I
wish some information in regard to mix
ing fertilizers. 1 want a ton of fertil-
izer containing the following: Acid
phosphate, per cent; nitrogen,
per cent and muriate OF potash, per
cent. 1 want to mix at home. for l can
not get a ready mixed fertilizer that
contains enough potash to suit me. VIII
this mixture need any rich soil? l do
not have anything to do with the for
mulas that cost So to IS each.
TO prepare a mixture containing PEI
cent Of nitrogen, per cent of phosphor-
ic acid and 8 per cent of potash from
high-grade nitrate of soda, 1G per cent
acid phosphate and so per cent muriate
of potash, you should proceed as Follows:
Mix together 260 pounds of nitrate Of So
GA, 1000 pounds of acid phi osphate and
$40 pounds of potash. This will give
you a total weight of 1850 pounds, and
70 Ia hay 70 adj
of rich earth. We would not advise you
to use the nitrate Of soda as the sole
source of nitrogen, however, for ordinary
farm crops as IT is too readily soluble
in the soil, and a part OF it is liable to
be lost through teaching and washing
before the crop can utilize 1t. 1t is bet
ter to put 100 pounds of nitrate OF soda
in the mixture and use 200 pounds or
dried blood TO supply the nitrogen. Since
blood and nitrate of soda are both
quickly available you may use with al
vantage 100 pounds of nitrate of soda
and 400 pounds of 6.lS per cent cotton
seed meal. In that case you would only
need to add $50 pounds Of earth as fill
Ter. You may buy these raw ingredi-
ents, If you find it cheaper and better
to do so, and mix according to the for
mula suggested with safety and salts
factian 1t is much more difficult to
cry, and you should bear this point in
mind on are certainly to be com
mended in not buying the formulas from
persons who ask So to So for them, as
you can secure all the formulas you
need free of cost. 1t is always well, of
course, situated as you are, to ask your
fertilizer dealer whether he can furnish
you with the formula or not. In case
you cannot obtain it and deem 1t essen
- From
your land, then you may very properly
attempt to mix it for yourself along the
lines indicated.
FORMULAS SUITABLE FOR TRUCK
CROPS.
VI. S. H., Philomath, Ca, writes:
want to know the best fertilizer to Use
on tomatoes, potatoes and onions. i have
plenty of stable and barnyard manure.
What is the best for compost? l also
have a lot of earth under my horses
which seems to have some good fertiliz-
ing properties. Can 1 use it as a help in
compost?
Both Irish potatoes and onions give
their best results on loamy lands, which
contain naturally a good deal of vegetable
matter. Where 1t Is desired to grow
them on lands that are at all deficient
in humus. therefore, the best results will
always follow when liberal applications
of yard manure are made to the land.
If the manure is well rotted. 1t may he
broadcast over the surface at the rate
Of five to ten tons PEI acre. Twice this
amount for onions will not be too much
to use. The fertilizer should be worked
into the soil with a. disk rather than
plowed under and covered deeply. OF
course. the land should be thoroughly
plowed and we'll prepared before the
manure is applied. In addition to this,
fertilizer should be used on this land
