REPORT OF DR.. E. NJ. PENDLEToN.
DR.. E. N. Pendleton, professor
of Practical Agriculture in the
State College of Agriculture at
Athens, read a long and interesting
report of the results Of his expert
ments before the recent State Ag-
rieultural Convention at Columbus.
At the conclusion of his report Dr..
Pendleton presents the following
summary:
To sum up the practical bearings
ofthese experiments, they teach:
i. That there is q great vast OF
ammonia when Peruvian guano is
used in its concentrated form; it
should be miSed with superphos-
pfkte, >,ikaline salts, etc.
2. That no combination of salts,
leaving out soluble phosphate acid,
will pay on our worn soils.
3. That taken separately none
of the salts sold as fertilizers to
make home compounds will pay.
Their virtues, if any, must be in
chemical action upon each other,
and the substances with which they
are composed.
i. That ashes treated with sui
phuric acid will greatly improve
their fertilizing qualities.
5. That two hundred pounds Of
a good ammoniated superphosphate
is about the quantity to be used on
an acre of cotton.
6. That a soil sbounding in veg
etable matter will pay much bet
ter per cent. with commercial fer
tilizers than one having but little
of this substance.
I. That large amount Of fer
tilizers (say half a ton per acre)
will not pay with low priced cot
ton.
8. That with good cultivation,
good fertilizers will pay, even at
the lowest rates of cotton but with
bad cultivation, they will hardly
pay at any price.
9. That while potash is more
indispensable to plant life than So
da. the latter may replace the for
mer under certain circumstances.
10. That the bi-phosphate of
lime, being less soluble in cold wa
ter, is not SO efficient as the BIZ
phosphate as fertilizer.
II. That stable manure, either
fresh Or rotted, applied with high
graded superphosphate, makes u
very efficient fertilizer for cotton.
y. That cotton seed applied
with the germ killed, for green, if
put in deep in conjunction with
good superphosphatc, makes i
powerful fertilizer.
13. That lime should never be
used in conjunction with super
phosphate, and the application Of
superphosphates to calcareous soils
is of doubtful utility.
Il. Fertilizers applied during
the growth Of the crop, to keep up
"a supply of nutrition, the rootlets
will not pay under ordinary cir
cumstances.
Is. That ammonia is the most
active form Of nitrogen, when. ap-
piled as fertilizer, and that organ
ic nitrogen in certain albuminoids
is more effcctual than the nitrateS.
IL. That the value of nitrogen
and phosphorlc acid to farmer d.
pends on their forms and combina-
tions, not their commercial value,
which is rated according to the
law Of supply and demand.
II. That the application Of SOL
uLle manurcs in liquid form is
better and more efficient than when
applied in the dry state.
Is. That lime will pay on soils
abounding in organic matter; Oh
other soils its application is of
doubtful! utility.
l9. That subsoils do not gerni-
nate seeds or grow plants like sur
face soils.
20. That early planting Of cot
ton will not produce as much as
that planted later, when the ground
becomes warm, and the plant is
not retarded, but grows off vigor-
ously and healthy.
