WOOD ASHES AS A FERTILIZER.

q Formula For Artificial Ashes That HAY
BE Mixed at Home.
Next TO stable manure, wood ashes
come nearest to meeting the farmers
wants Most lands are benefited by
the application of wood ashes. While
valuable chiefly for their potash, this is
by no means their only merit Professor
Atwater, excellent authority, says:
Ashes contain all of the food ingre-
dents that the plants require from the
soil, except one-nitrogen. By their
chemical action they render the inert
nitrogen OF the soil available to the
crops. They also help to Vet free pot
ash and other mineral ingredients of
plant food that are locked up in soluble
combinations in the soil. They improve
the mechanical condition of the soil.
They make heavy soils lighter and coun-
teract the ill effects of drought. Thus,
by virtue of what they themselves con-
tain and what they enable soils to fur
nish, they constitute practically com
plete fertilizer. Hence, like stable and
yard manure, they are fitted for all
soils and all crops And, finally, they
are generally applied in large quaint
ties, are exposed to scarcely any waste
until they are used by the plants, and
therefore their effect is as lasting as it
is valuable.
In many localities the high cost of
wood ashes prevents their use. To meet
this obstacle, Davis, in his book on
Improving the Farm gives formula
for artificial ashes which, while it may
not analyze precisely like ashes, has on
repeated trial given practically the
same results. For one ton: 500 pounds
ground bone. ID per cent phosphorio
acid; 800 pounds superphosphate, 10
per cent phosphoric acid; 400 pounds
murlate potash, 80 per cent; 200 pounds
sulphate magnesia, crude, IS per cent;
600 pounds gypsum, Or land plaster.
The formula can be varied. For use
on grass as a permanent manure the
dissolved bone can be omitted by using
more of the bone dust. The chief advan-
tage of using the superphosphate is that
it gives quicker action and makes the
fertilizer do better work when first ap-
piled. And in those localities and on
those soils where plaster produces no
good results this may be substituted by
good loan. It should be thoroughly
pulverized. On many soils the magnesia
can be omitted altogether, so that if it
were made up of 500 pounds of ground
bone, 300 pounds Of superphosphate, 400
pounds of muriate potash, 800 pounds
of gypsum or loan, it would make a
first class fertilizer, though not CORE
spending fully to the ashes.
In using this it will be borne in mind
that the bone supplies phosphoric acid
and lime The potash salts give the
potash needed, and the superphosphate
affords lime, phosphoric acid, sulphuriC
acid and a small percentage of nitrogen
This last element is very valuable one
which ashes do not afford at all. If
gypsum is used, it also supplies lime and
sulphuric acid, for it is of itself simply
sulphate of lime. Sulphate of magnesia
gives also sulphuric acid and magnesia.
A fertilizer thus made up has proved
of great value on meadows, pastures,
sown grain and hoea crops of all kinds.
1t is permanent in its influence, as the
bone dissolves slowly, while the mechan-
ical action unlocks latent elements of
plant food and makes them available
for immediate use.
