EXPERIMENTAL DATA CONCERNING
LIME.
A correspondent writes: Have you
made any experiments with lime and
what conclusions have been reached
from themP
Only a few preliminary experiments
have been made to determine the eff
cheney of lime as soil amendment in
Georgia, but those carried on to date
indicate that lime is deficient in the
great majority of our soils and that
liberal applications of this material
will be beneficial. OF course, lime
should be used as soil amendment.
that is, for sweetening the soil and i'm
proving It's mechanical condition, fav-
oring such biological functions essen
tial to plant development, and setting
free, a part of the unavailable plant
food held in the soil. 1t SHOULD be used
as a corrective but not as a source or
fertilizer. There is some danger that
many Of our farmers may draw this
conclusion because lime when first ap-
piled to many lands will give good
results because of the fact that 1t does
set free certain forms of plant fooo
rather rapidly. Farmers using lime
should remember that crop rotations are
essential to secure the best results, ana
that the blowing under of green legu-
minous crops or applications of farm
yard manure will be found, necessary.
In certain experiments made on the col
Iege farm we have found lime to in
crease the yield of corn from 15 to 20
bushels per acre. OF course, this line
was applied in connection with COM
mercial fertilizers, though on cneck
plats where lime alone was used in COM
parison with no fertilizer excellent re-
suits were obtained from the use OF
tic lime per acre applied preferably In
larger amounts in this state to good
advantage, and that better results VIII
be obtained on many of our south Geor-
gia soils where the supply of lime is
considerably lower than that met with
in The Piedmont section. We would ac-
wise the use of at least one ton of caus-
tic lime per acre applied preferabl in
the fall and some time in advance Of
the application of commercial fertiliz-
ers. The lime should be put on as a
top dressing and worked into the soil
with a harrow, but never plowed In.
A ton of caustid lime has been shown to
have about twice the sweetenIng pow
err of a ton of finely ground rock. In
sections where lime rock of high grade
is found in considerable quantity the
unburned lime can often be used with
advantage. 1t should be applied at the
rate of one to three tons per acre once
in three to five years. Where the I'M
ground rock is used il is important 10
remember that It's availability will be
FASTENED If used on soils well supplied
with vegetable matter.
INFLAAIED UDDER AND ITS TREAT
MENT.
G. F. E., Winder, Ga, writes: I have
a very fine COW that has been bothered
with milk cakes in her sack every once
in a while since she brought her last
calf, which was last May. She had milk
fever, but got we'll of that. In few
weeks one of her teats became caked
and would stay that way a day and
night and then be all right for a week
or ten days and then another one would
cake up. I can not understand what
causes the trouble. 1 would like to
know what to do for her to keep her
udder from caking.
The trouble to which you refer prob
ably started as an ordinary case Of gar
get, but may have become more or less
chronic in character. The causes OF
such a condition are varied. For In
stance, exposure to draughts, blows on
the udder or compression of the udder
from lying on 1t may all be predisposing
agencies. It is likely that your COW
runs in the open. but IL she is confined
in stable with . board floor, she
