Is it not astonishing that we have
given so little thought and attention
to study of the soils of our state
when this knowledge is essential TIC
the effective and economical grow
| ing of crops? Yet, it will take many
years to complete the soil survey OF
Georgia on the basis of approprla-
lions received for this work at pres

if they had their way, would ellm1-
nate the small fund now made avail

We cannot hope to develop a perma-
nent or worthwhile type OF agrlcul-
ture without an intimate, accurate
only be acquired through the aid OF
prolonged and carefully carried o out
chemical research work 1t is diff
ficult to see how the state can al
ford to neglect the liberal endoW-
ment of work of this character. IL
Importance to the advance of the
commonwealth that it's liberal sup
port would be regarded as necessary
to the public welfare.
Attention is directed to the fact
that under boil weevil conditions we
must figure on raising one bale OF
cotton per acre. Under the most
favorable circumstances, not over
fifty pounds of nitrogen, thirteen
pounds of phosphoric acid and twen-
ty-seven pounds of the potash con-
tanned in the Triton sandy loan de-
become available to a crop, OF cot
ton. Let us supplement this Ter.
tilizer somewhat on the basis OF
the needs of the cotton crop and for
the purpose of supplying the ele-
ments in which the soil in question
is shown to be most deficient. What
is the result when no fertilizer was was
used? The yield of cotton was 913
pounds: with $40 pounds of fertilizer
supplying twenty-eight pounds Oh
nitrogen, siXty-seven pounds OF phos-
phoric acid and fifty pounds of pot
ash, the yield became 1929 pounds
of seed cotton per acre. The fer
tilizer used cost $20.4S. The profits
from it's use were $40,32 per acre.
apply these results to the cotton
lands of Georgia and see the vast
potentialities which lie ahead in cot
ton raising. When the composition
of the soil is understood and its
deficiency is supplied through the
use of commercial fertilizer on a
basis commensurate with its needs
the yiel dper acre is greatly IN
creased and the cost Of growing 1t
greatly reduced.
This presents all the evidence
needed to demonstrate even to the
most reluctant mind the Importance
of providing our people with an IN
innate knowledge of the SITUATION
and Of giving the rising, generation
of boys and girls that charactef OF 81
to interpret soil types with skill
and intelligence. Thus alone can we
put our agriculture on permanent
basis and make the children OF tu-
ture generations the dominating tac-
tors in the situation: ro
