would open a furrow as you suggest and
fill 1t with the compost, and then mix
the fertilizer with it and plant the pota-
toes above but not in contact with
! the fertilizer. Blood furnishes nitro
| gen in an excellent form for pota-
toes, and it becomes available with
sufficient rapidity to meet the needs of
this crop.
FERTILIZERS FOR TOBACCO.
A P. D., Dover, Tenn, writes: 1 intend
planting several acres of tobacco on
| Cumberland river bottom land next sea-
son. This land is on a slight elevation,
| aud is black sandy loan. Several sue
! cessive crops of tobacco have been made
I Oh same land very successfully yielding
from 1000 to 1900 pounds per acre Small
amounts of fertilizer and some barnyard
manure have been applied at various
times. II from this meagre information
you can give me a suggestion as to the
kind iof fertilizer to use, 1 will appreciate
it very much.
| We Judge from your letter that you
desire TO grow a large yield of tobacco
irrespective of color and quality of leaf.
In other words that you are raising dark
tobacco, and therefore there will be no
objection to using a considerable amount
of vegetable matter on your land. Where
quantity of tobacco irrespective OF cplor
is desired vegetable matter may be used
very freely. In the light tobacco regions,
however, must be used sparingly and with
discretion or the crop will contain so
many mahogany wrappers as to reduce
it's value very materially. 1 would suggest,
therefore, that you use from five to ten
loads OF farInyard manure per acre if you
can secure the same, and fertilizer
ccntaining the following ingredients LOO
pounds of ground fish, $50 pounds of nj
trate of soda, 100 pounds Of bone meal,
and $50 pounds of sulphate of ammonia.
This would make an application of loo
pounds per acre and the mixture would
contain approximately 153 pounds of am
monia, log pounds of phosphoric acid and
LIS pounds of potash. The ammonia in
this mixture would be equivalent to 126
/ pounds of nitrogen. The percentage
composition of this fertilizer would be
about SO per cent of nitrogen, SO per cent
of phosphoric acid and 6.2 per cent of
potash. 1t would be considered lower in
lphosphoric acid and potash than is often
advised for tobacco, but since exceptional
,ly good yields have been obtained from
this mixture we would suggest that you
try it. OF course, where ground fish can
mot be obtained, tankage or blood or cot
ton-seed meal may be used as the source
of nitrogen. In tests where this mixture
was used, a yield of better than 1900
pounds OF tobacco Of fine quality was OBJ
tanned and a good profit per acre made.
The land was also left in fine condition
to seed to oats or wheat without the use
of additional fertilizer. We advocate the
use OF a rather high percentage of nitro
gen as you will see on account of the i'm
portance of growing the leaf quickly and
uniformly in order to secure a large
yield and the best quality of product. or
course, a great variety of formulas may
be suggested for tobacco, but we be-
lieve the one offered is a fairly salts
factory one in view of the success we
have had with 1t.
A GOOD FERTILIZER FOR COTTON.
| A subscriber, Cumming, Ga, writes.
What grade of fertilizer is best for cot
ton on red land and how much should be
used per acre. Also what grade of fer
tilizer is best to use on sandy land. Please
give me the amount of each ingredient
which goes to make up the fertilizer.
| A very good fertilizer to be used under
cotton on red land may be prepared as
follows: Mix together AGO pounds of dried
blood containing at least 13 per cent nj
ltrogen; 1000 pounds of acid phosphate
and 100 pounds of muriate of potash To
this you will have to add $50 pounds On
leaf mold or we'll rotted farmyard ma
nure to bring the total up to 1000 pounds.
This mixture would contain approximately
l3 per cent of available nitrogen, per
cent Of available phosphoric acid and
per cent of available potash, and If used
at the rate of 500 pounds per acre should
answer well on land such as you de-
lscribe For sandy land we would in
crease the potash to $50 pounds and les
sen the earth proportionately. If the land
| is very sandy we would add at least 100
pounds more Of acid phosphate. A high
grade cotton seed meal containing at
least per cent of nitrogen may be used
in place of the blood If desirable. In that
case you would have to use at least $40
pounds of meal to secure as much nitro
gen as would be contained in 460 pounds
of dried blood carrying IS per cent OF
nitrogen. High-grade cotton seed meal
will In our judgment furnish the nj
trogen about as cheaply as the blood.
We think you will find 1t advisable to
put as much vegetable matter into your
soil as possible for cotton. At least two
tons per acre of we'll rotted compost or
yard manure will be found highly bene-
fetal along with the amount of fertilizer
suggested.
| YARD MANURE FOR COTTON.
| -
| L. E. t. writes: I want your opinion
about the best fertilizer for sweet po-
tatoes. and amount per acre. Is it prac-
4 cal to use stable manure for all nitrogen;
If so, how much potash and acid should
II use per acre for best results? How
many pounds OF nitrogen are available
in ton of stable manure the first year?
| Yard manure ordinarily contains from
is to u per cent Of nitrogen. Where the
animals are fed on a ration containing q
large amount of cotton seed meal or 9TH
er food rich in protein the manure may
possibly run as high as is per cent of
nj rogen. Probably not over pounds OF
nih ogen would therefore become avail
able for each ton OF manure used dur
ling the year. While IL is possible, there
fore, to supply the needs of the potato
crop with farmyard manure the applica-
ltion would have to be heavier probably
