LIME NOT A FERTILIZER.
it is, However, Indispensable to
Plant Growth, but Must BE

Lime is absolutely Indispensable to
plant growth, yet 1t is required in COM
paratively small amounts. Our cereal
crops, for instance, contain about two
pounds of phosphoric acid and three
pounds of potash for every pound of
lime, while all soils except the clear
sand contain much more lime than
phosphoric acid, and ut least as much
lime as potash. The abundance of lime
is shown in the fact that water which
has been for any length of time in
contact with the soil is always hard;
but only one grain of lime to the gal
Ion of water, a quantity that could not
be detected under ordinary conditions,
would supply twice the amount or
lime needed by a clover crop, which is
the only one of our ordinary farm
crops that contains as much lime as
potash.
Lime, however, serves other J,ur-
poses than as simple plant food. One
of the most important of these is The
correction of acidity in h soil. When
a soil becomes acid, clover will not
thrive upon it and when this condl-
tor occurs an application of lime may
be necessary, a point thoroughly DEM
onstrated at the Ohio experiment sta
ton, where a luXuriant crop of clover
has been grown on lined land, while
the clover on unlimed land along side
was a complete failure.
Lime performs still another import
ant function in l%iberating plant foo
already in the soil. If a little lime be
mixed with strong manure, such as hen
manure, an odor of ammonia will be-
come apparent. This mea that the
lime is l~ibefating the ammonia from
the manure and that it is escaping in
to the air. If lime be mixed with the
soil similar action will take place. 1T
a crop be growing upon the soil it may
absorb part of the escaping ammonia
and a larger crop is made at the eX-
pense of the soil stores of plant foOG
and if these are not maintained by ma
ruring or fertilizing the soil will soon
refuse to respond to lime, because all

poorer than if no lime had been used.
European farmers who have used
lime for many years have become so
convinced of its injurious effect when
used in this way that they say lime
enriches the father but impoverishes
the son." and it is customary in some
places to prohibit the use Of lime in
leasing land.
Some of those who have lime to sell
in Ohio are advertising it as a f%ertiliz-
er, claiming that it is better and
cheaper than phosphate" But the Ohio
experiment station would earnestly
warn all farmers against using lime as
a substitute for manure or fertilizers.
When used as an adjunct to liberal ma
nuring or fertilizing, lime may be used
to perform a most important service,
but it's use as a substitute for manure
or fertilizer means ruin to the soil.
Where clover Is failing to grow the
use of lime is indicated. For this our
pose the common quicklime is all that
is required. A very convenient form Of
lime is made in some parts of the state
by grinding quick-lime into a coarse
meal. This can be applied with the
fertilizer drill or the manure S%preader,
using about 1000 pounds per acre. 1t
costs $3.50 to $3.50 per ton at the
kilns. 1t must not be expected that
lime alone will bring prosperity to the
clover crop. In the Ohio stations eX-
periments, lime produces very little ef-
feet on clover on unfertilized land.
Manure or fertilizer must first be used
before lime will produce any lasting.
benefits.
Farmers should not be misled by the
claim thai certain methods of prepar-
ing lime will prevent its injurious eff
feet. If those methods do what 10
claimed for them they will prolong
and increase thai effect and the appar-
ent increase of crop which follows the
application of such lines will be paid
for by a certain and more complete inn
poverishment of the soil. Lime is not
a fertilizer and it's use as a fertilizer
will bnng ultimate loss.-Press Bulle-
