Silos and Crops Suited to SiIage
Production

Production
s. T. K, Meigs, Ga, writes:
What is the average yield per
acre in tons of corn for silage?
What is the relative value of q
solid cement silo and a cement
: block silo? Do you not think
that land ought to have a bal
anced ration the same as live
stock? I can procure cornstalks,
cane pomace, fodder, pinestraw,
oak leaves and muck out of the
creek bottom. I would like to
know how to use these materials
SO as 10 be of the most benefit
to the crops.
The yield of corn si1age per acre
varies materially with soil and eli
mutic conditions. An average yield
of from six to eight tons per acre
would probably be very good. We
have raised as much as twelve tons
per acre on the College farm. We
base our crop acreage on an IN
titcipated yield of from seven to
eight tons of corn silage per acre.
We have ceased to use this crop,
however, for silage purposes, and
now depend entirely on sorghum
and kaffir corn planted in alternate
rows. This crop will staud droutE
much better than corn and gives a
yield Of from ten to twelve tons
per acre under aVera &c conditions
We have harvested as much as fiji
teen tons per acre of this crop, ,ut
do not think it safe to count on
more than nire OF ten tons.
We regard the monolithic silo as
the most desirable type to build in
Georgia for permanencY. The hol-
low tile silo is all right, and has
given good satisfaction. There are
some who prefer its use to that Of
the monolithic structure. We are
only expressing our own opinion
with reference to this matter as
based on our experience and obser-
walton.
Land, of course, should have a
balanced ration just the same as
livestock. Crops make varying de-
mands on the soil. Legumes draw
more heavily on the phosphoric acid
and potash supply Of the land THAI
on the nitrogen supply. In fact,
under normal conditions, they OBJ
tain the nitrogen they need from
the air. Corn needs to be literally
fortified with nitrogen. This may
. come from two sources of course:
From yard manures or green crops
plowed under or from commercial
sources. Cotton needs a complete
fertilizer. Truck crops need to be
supplied A. relatively large amount
Of all tho elements, but particu-
1arly Of nitrogen. Pomace and fod-
der can be scattered over the land
to advantage. It is cdoo to use these
materials on Galded spots. Corn
stalks. if not harvested should be
plowed under. Pine straw and oak
leaves can be composted to ad.
vantage for the Improvement of the
land. We do not believe YOU viii
find it profitable to haul muck from
the creek to your uplands. The
cost involved is too great.
Applying Calcium Arsenate for
