;;AAppose that you decide to plant cot
ton on the ten prepared plots for the
purpose of finding out what fertilizing
constituent is most needed by your soil
when growing cotton. Plant the COT
ton in your usual manner, after care
full preparation of the soil of the plots,
thoroughly blowing and narrowing tile
plots in order. Then apply the f.
filters as follows
No. mo fertilizer.
No. 2-143 pounds of cotton seed
meal
No. 300 pounds of IA per cent
acid phosphate.
No. so pounds of kainit.
No. mo fertilizer.
No. 900 pounds of acid phosphate
and 143 pounds of cotton seed meal.
No 7-143 pounds of cotton sed meal
and so pounds of kainit
No. 300 pounds of acid phosphate
and so pounds of kainit
No. 300 pounds of acid phosphate
80 pounds of kainit and 143 pounds Of
cotton seed meal.
No. 1880 pounds air-slaked lime.
In many of our Georgia soils lime Is
sadly lacking. and 1t may be just the
thing needed by the soil, in conjunc-
ton with certain other fertilizers; to

Ing fertilized Plot No 2. mark off a
strip 212 feet in width diagonally
across the plot, that is running from
one corner to the opposite corner. APP
ply to this strip so pounds of air
slaked lime. and work 1t in we'll with
the soil and other fertilizer with a
rake. Do the same with each of thu
other plots, emitting No. 10. Thel
when the crop begins to grow, if lime
was specially needed by the soil in am
of the plots, you ought to notice &
marked superiority in the 2b foot
strip which runs diagonally across all
the rows in all nine plots.
In the above fertilizers It is pre-
sumed that the acid phosphate is the
kind most usually sold containing IA

to contain per cent OF nitrogen, s.
that l43 pounds Of it supplies 10
pounds OF nitrogen to the plot. and the

In applying the fertilizers observe
the following precautions Sow each
fertilizer on the plot to which it is to
be applied broadcast, using your best
care and judgment to distribute the
fertilizer evenly over the entire plot.
In order to get an even distribution IL
is best TO SOW in such quantity that
you viii have to go over each plot
at least twice to get all the fertilizer
distributed. Take care not to SOW
while the wind is blowing, as it may
blow some Of the fertilizer on to the
adjoining plots. After sowing har

all the plots exactly alike, except as
to the fertilizers applied. Prepare
the ground in each plot the same.
plant the cotton all at the same time,
and always cultivate the same and at
the same time each day. Take pains
to have the same number of plants in
each row. 1t will be well to keep a
notebook. with a page for each pllt,
in which to record your observations.
