used with impunity in a mixture

Good organic sources of nitrogen are

Cotton Seed versus Commercial
| Fertilizer
E. J. B., Little Rock, Ark,
writes: Given a price of $4,000
per ton for cotton seed what
| would be the approximate fertl1
lizing value for tone of 1922
commercial fertilizer? Also at
this price for seed what would
| be the relative feeding value OF
ton of mixed feed consisting OF
| eighty per cent of hulls and
| twenty per cent of meal, the
meal being worth $4,000 per ton
and the hulls $500?
A ton of cotton seed contains ap
proximately 62.4 pounds of nitrogen,
| 80 pounds of phosphoric acid and 81
! pounds Of potash. Commercial nitro
7 gen can, we think, now be bought IN
of available plant food. Available
phosphoric acid will cost approx
mateIy &c. The value to place on
potash is difficult to determine, but
Csc per pound of available plant food
does not seem unduly high under ex-
figures to the fertilizer content of
cotton seed, we find that a ton of
cotton seed would contain plant 1000
| constituents worth approximately
| $23.32. With these figures in hand,
it should be easy to determine
whether cotton seed will prove cheap
er and more serviceable if used as
a fertilizer than sold to the oil mill.
A ton of cotton seed is not well bal
a1ced as to food constituents. You

spect, one would need to apply it in
association with acid phosphate and
some addition potash. Our experience
believe that cotton seed by. itself
was an economical or satisfactory
fertilizer. Moreover, the oil it con-
tains is not Of any value as
plant food but rather a detriment
to the soil. Personally, we would
| prefer to exchange our cotton seed
on best basis possible, take the meal
thus secured and feed it and then re-
turn the resulting manure to the
soil. This will insure the farmer re-
ceiving the largest possible return
for his seed under existing condt-
lions.
Cottonseed hulls have a feeding
value about equivalent TO low
grade Of mixed hay or possibly a
! poor grade of corn slower. 1 would
rate these as standing one-third low
er in feeding value than good quail
ity of timothy hay or slower. This
should enable you to determine a
fair price for hulls, based on the
comparative feeding value set forth
above. For the purpose of feeding

cottonseed meal is equivalent to
| about one and three-fourths pounds
| of corn meal. We do not regard cot
ton seed as a satisfactory feed for
cows Or beef cattle. They are too
laxative and besides that, the butter
seed is not Of satisfactory quality.
I think a ton of feed mixed as you
propose would prove more profitable
to feed beef or dairy cattle than cot
ton seed at $4,000 per ton, although
the feed as mixed even costs the
The Merits of oyster Shell Lime

Lime is applied to land chiefly for
the following purposes: To correct
| acidity which is its most important
function. 1t has been found for in
stance that the bacteria which as
sociate themselves with leguminous
crops find it difficult to develop in
an acid soil. Hence, when this con-
dit1on develops in the land, it is very
difficult as rule to grow 1egu-
nous crops on satisfactory basis.
Lime is also used as an amendment
III correcting an impaired physical
condition of the soil 1t is also used
soils and making light soils more re-
tentive of water. These things be-
ing true, we would be disposed to
buy that type of ground lime rock or
ground oyster shells which would
furnish carbonate of lime in the
cost.
We are disposed to think that $500
for the material about which you
write at Mobile, Ala, would re-
du1re you to make a higher outlay
for carbonate of lime than you would
have to pay for it in a rock mined
and ground nearer your present loca-
ton. Any company that is now SELL
ing finely ground, raw limestone rock
Will no doubt be glad to furnish you
with an analysis of the same, and
you can easily judge whether you can
buy the carbonate Of lime at a lower
cost than in oyster shells at the price
indicated. In the event you could
use locally ground rock at a lower
cost, 1 would certainly purchase and
use it. One of course would only ex-
pect to handle limestone in bulk.
Crops to Plant in the Fall
c. r., Atlanta, Ga, writes:I
have recently bought a farm
and am going to live on it my
what crops can be planted to ad-
vantage this fall, and any other
information you can give me
that will be of service.
There are only a few crops which
can be planted satisfactorily in
G Gs0ggfa this late in the season ato
may still be sown with consider
able promise. 1t is doubtful if Grim
son clover can be seeded this late
with any prospect of success. Occa-
sio1ally, we have very mild win
ter. Under such circumstances, late
tory.
We have conducted many tests
here at the college with all classes
OF cereals, and we find that early
planting is more effective and prof
table. If expecting to SOW any
winter cereals this fall, we would
try and get the land in shape as
quickly Is possible. This, of course
will be difficult to do because Of
the dry weather which has pre-
vailed for so long a period Of time
Our experience indicates that plant
ing the land before it has been
well prepared, is undesira BILE.
Wheat, of course, should be sowr
on every farm to some extent for
bread stuff. In spite of the" falling
off il the price of wheat at this
time, the world is not over sup
piled with this cereal, and the
chances are we will need a large
Equality next year.
Oats should be seeded as soon as
