AGRICULTURAL EDUCATION

drainage, structure of soil and sub
soil, the cropping system, etc, must
be taken into consideration. Thus, it
may happen that two soils of APP
prONimately the same chemical COM
position may differ greatly in their
crop producing power, owing to some
of these factor. 1t is important,
therefore, to know the soil type and
the various physical conditions in
fluencing it. as well as the chemi-
cal composition in order to make an
Intelligent effort to improve and
build up the soil.
To use the information contained
in these reports with respect to any
piece of land, one should first locate
the tract of land on the map, remem-
boring that one inch on the map rep
resents one mile, and that one square
inch equals $40 acres. The types are
identified by comparing the colors
on the legand at the right of the
map. For example, a man having
farm of $40 acres one mile southeast
of PARROT, along the PARROT and
BrOnwood road, wishes information
concerning the types of soil on his
farm. By measuring one inch from
the location of the town he will
reach a point on the map represent
ing his land. Since he has $40 acres,
his farm will be represented by one
square inch on the map. Then by re-
ferring to the legend on the margin,
he finds that his farm consists chief
ly of Triton sandy loan, Greenville
clay loan and Ruston clay loan.
Turning to the body of the bulletin
he can find descriptions of these
types with recommendations as to
the crops for which they are adapt
ed and physical conditions that need
to be corrected The chemical report
gives the amount of plant food in
these types together with sugges-
tions for improving them and in
cfeasing their fertility.
Field Experiments
In conjunction with the field work
of the soil survey, the agronomy di-
vision of the college is conducting
field experiments on the principal
soil types of the state. The soil type
influences the fertilizer require
ments and determines to large ex-
tent the crops that will do best on
any tract of land. For this reason
the fertilizer experiments are being
conducted with, the aim in view Of
determining the best system of fer
tilization for each soil type. 1t is
important, therefore, that farmers
should famiIiar;ze themselves as
much as possible with the soil types
they are farming, as this will great
ly aid them in applying the data OBJ
tanned from the fertilizer plat work
and other experiments.
Terrell county is situated in the
northwestern part of the state. The
southern boundary is about 62 miles
north of the Georgia-Fiorida line,
and the western boundary is approx
imately 80 miles east of the Ala
bama state line. The area of the
county is 1874 square miles, or 213,-
$50 acres. Seventy-four per cent Of
the total area of the county is class
ed as improved farm land in the
United States census report of 1910.
There were at that time 2,741 farms
in the county, averaging 64.9 acres
each. Only 1871 ( per cent of the
farms were operated by the owners.
The county lies entirely within
the coastal plains soil province, and
the topographic features of the coun-
ty conform to the general topogra-
ply of that region, consisting Of
