of the
Director of the
Kentucky Agricultural Experiment Station.
For the Year 1919.
The past year has been one of progress as well as diifi- V
_ culties for the Experiment Station. Changes in person-
nel, due to opportunities for material increase in salary, have
affected the progress of work and made conditions difficult.
The projects undertaken have shown favorable progress in i
spite of the difficulties and viewed from a comparative basis.
satisfactory gains have been made.
- The position and prospect of agricultural investigation
thru the experiment station is so concisely and clearly set
forth in a report of the Committee on Experiment Station
Organization and Policy presented at the Chicago convention
of the Association of American Agricultural Colleges and Ex-
periment Stations, November, 1919, that a. portion thereof is
. quoted as applying not only to the national situation but
equally well to the situation so far as the Kentucky Agricul-
tural Experiment Station is concerned.
"During the period of the world war, when agriculture
was playing such a vital part and the accumulated results of in- ‘ ·
vestigations were being drawn upon to an unprecedented cx— ’
. tent, the state agencies for agricultural research remained
practically at a standstill in their development, and in not a
few eases lost ground. Investigation did not cease but it was
interrupted and for the time being it stopped growing. Its
efforts were in part diverted and it lost many of its workers,

 J2 Thirty-Second Ann-ual Report
and when the war closed the changed economic conditions
left it in a weaker condition `and more in need of support than
it has been for a decade ....
_ "There is probably no branch of the college which has
felt the increasing cost of maintenance more than the experi- »
ment station. It is a large employer of labor, it is often re-
quired to buy considerable amounts of feed for its experi-
mental animals, and its laboratory work calls for new ap-
paratus and continuous replenishment of supplies, all of which
have increased enormously in price. Salaries have advanced
some, but not in proportion to the other expenses.
"It was inevitable, therefore, that agricultural investi-
gation should be seriously crippled all along the line; but be-
cause the stations work in a quiet way Ellld have made an cf-
fort to adapt themselves temporarily to the resources at their
command the nation-wide extent of the setback has not been
generally realized. 'l`he etfeets of a decline in station activ-
ity do not become apparent at once, and the situation has
been further obscured by the extensive outgiving of informa-
tion which is 11C\\' to those who receive it. `
"'l`he steady and unrestricted progress of investigation
is so fundamental to college teaching a11d to the success of the
great movements inaugurated for vocational instruction and
agricultural extension that it has been felt desirable to lay bare ,
the actual conditions the stations are confronted with and the
outlook t`or their future .... t
"lt seems clear that if the experiment stations are to
maintain the position they have held in the past and provide
the backbone ol' the whole system of agricultural education
and adva_ncement, they must receive larger tinancial support
from some source. 'l`heir prosperity and welfare are the con-
cern of every institution. Their advancement ought: to form
a definite part of every progressive policy of an agricultural
college .... M
'l`he problems ot’ agriculture are so varied and so press-
ing that the work of the Experiment Station must constantly

 · Kentucky .·1g1·z'cuZt1n·al Escperimeut Station 13
develop and enlarge if it adequately meets the needs of the
state. Frequently the thought is expressed that there is avail-
able a store of agricultural information far in advance of the
praetis of farmers in the stateand that Experiment Stations
may rest content with the progress that has been made and
i await the development of farm praetis. A more pernicious
statement as to the true situation can scarcely be made. It
is true that in many phases of its work, the experiment sta-
tion is in advance of the average farmer. It is not true that ‘ A
experiment stations may rest upon their past efforts. Never
before has there been so pressing a demandfor new informa-
tion and for new investigations. Agriculture is a rapidly de- V
veloping industry. Requirements of this year may be much
changed five years hence. The development of new and cheap A
sources of nitrate or of phosphate may requirea new study
of the relationship of these essential elements to crop produc-
tion. Increased land values, the development of tenancy, all
mean that new studies must be made if agriculture is to se- _
cure the proper direction. Investigations must be begun months,
and sometimes years, in advance of the actual need of the in-
formation. Cost of production studies, for example, must be
well under way before their need, otherwise they are rela-
tively of little value as the extensive need passes and the study
is not used. Similarly, methods of disease control in plants
are often essential before actual and profitable production may
_ take place. Investigations of methods of distribution, market
demands and organization are required before information
may be given or effective practis outlined. _ ,
Certain phases of Experiment Station work require cm-
phasis, especially the economic aspect of agriculture that may . _
be studied under the general heads of farm management, mar- .
, keting and agricultural economies. The farmer is concerned
with the price of crops and live stock, the tendency of tenancy.
land prices, farm labor and methods of farm organization that
will enable him to meet new conditions as they arise. 'Ihc
experiment station and the Department of Agriculture are the

 r 14 Thirty-Seeonsl Annual Report
only orgnizations that may effectively carry O1] different in-
vestigations to inform the farmer and to indicate remedies.
Progress may be made in these or similar investigations or
Studies only when additional funds are available. The pres-
ent work which is in progress and which is fundamentally‘
necessary requires the total resources of the institution.
Needs of the Experimenti Station. As indicated i11 the pre-
vious paragraph, the development of the Experiment Station,
particularly of its functions of research, is essential to tl1e
progress of agriculture i11 the state, to the proper develop-
ment of agricultural extension work and to the furnishing of
new information for teaching. .This progress may be made
and functions exercised onlythru adequate financing. The
` Kentucky Experiment Station is supported by a state appro-
priation of fifty thousand dollars per annum. This must be 111a-
terially increased if the institution is to develop and to meet
adequately the agricultural problems of the state. Many
lines of investigation are essential. Perhaps tl1e 111OSt needed
at tl1e_ present time are those dealing with tl1e OCOllf)llllC p1·ob- ·
lems previously suggested. Additional land, equipment a11d
buildings a1·e required; soil CX])CI‘ll]1C]lt fields should be es-
tablished on every important soil type area i11 the state. Such
fields represent the most effective method of determining the
requirements neeessary for increasing and maintaining fer-
· tility. ln faet. there is no other 111ea11s of obtaining this in-
formation. Nine fields have been established; several more V
a1·e needed to meet the situation effectively. The expense of
each field is comparatively slight, but a11 investment must be
made and operating expenses allowed if the work is to de-
velop. Land with the necessary buildings, equipment and
funds for operation should he made available in certain sec-
tions ot` the state which would permit of eareful investiga-
tions i11 oreharding, i11 grass production, tl1e development of
live stock in the mountain areas, and investigations in the _
various truck crops near the larger cities. Only by so111e such
method of local studies may tl1e work of the Experiment Sta-
tion be 111ost effectively extended to tl1e sections needing it.

 Kentucky Agricultural ExpeMm·emt` Station 15
Additional farm land is required by the Experiment Sta-
tion. A farm of 243 acres is insufficient upon which to carry
out the various soil, crop and live-stock experiments. So long _
as this condition exists, the Station will be cramped for room
and it will be impossible to develop many branches of live-stock
investigations which are in demand by the farmers of the state.
New Projects. Each department, in determining its work T
systematically, outlines a certain problem or phase of a prob-
lem. This particular piece of work is designated as a project. _
Its purpose and the point at which it is carried on- are indi-
cated and a report on the progress of the investigation is made
from time to time. A final report is made upon its eomple-
tion and is published in the form of a seientine paper, bulletin
or circular. The following investigational projects were in-
itiated during the past year;
Experiments in calf feeding. A _
_ Experiments in the "up grading" and better manage-
ment of the type of hog found in the mountain districts of Ken-
tucky. ii _ _
Head lettuce investigations.

Additions to Equipment and Property Changes. ‘
During the year all outbuildings and barns upon the Ex-
periment Station farm were repainted and such repairs made
as were required to maintain the property. Few repairs and
no paint had been applied during the past several years. Many
of the structures were badly weathered and the expense in-
volved in the year’s maintenance cost was accordingly large.
New stalls and eqnipznent were placed in the dairy barn. V -
inodernizing the equipment and replacing stalls that had long
ago outlived their usefulness. The silo at tl1e dairy barn was
repaired and ehanged so that its capacity was increased. New
water piping was laid in the building and a new Scotch steam
boiler installed, replacing one that had been in use.

 . Kentucky Agricultural Experiment Station 17
About 200 rods of new woven wire fencing with steel posts
were erected and 1900 feet of road constructed. All main
' roads on the farm were repaired and put in order. ` ‘
p A Hereford bull was purchased to head the Hereford
. breeding herd and excellent specimens of the Shorthorn and
Angus breeds were added to the live stock. Three Guernsey
eows were urchased for the dair herd and s Jecimens of Buff
Plymouth Rocks, Anconas, Black Minorcas and pedigreed
birds of Barred and Vv'hite Plymouth Rock and XVhite `Wyan-
dotte were added to the poultry farm. _

Library. The technical library of the Experiment Station
y has been inereased by 560 volumes during the past year, the
total number of accessions to date now being 7,550. The
library has received during the past year 143 periodicals, more
o1· less technical in their nature and essential to the work of
the various departments of the Experiment Station. This
library is being increasingly used by the students of the Ag-
ricultural (`ollege, as it represents a source of material through
which students may best secure technical information. The .
use of the libraryiby students emphasizes the lack ot reading
1·oom space, and has made imperative additional accommoda-
tions t`or shelving purposes as well as for readers.
A new service was inaugurated by the library during the
past yea1·. Employees of the extension division or other em·
ployces located away from the Experiment Station may secure ‘ .
books and other literature on technical subjects by writing to
the librarian. This material is sent out in as complete a form
as possible and may be retained for a period of ten days or two
weeks. Similar service is given relative to information ap-
pearing in agricultural journals or in technical publications.
The work has been under the direction of the heads of
departments and the progress of the several departments is Q
very largely due to the close attention and effective adminis-
tration ot the following departmental heads:
George Roberts, Head, Department of Agronomy.
E. S. Good. Chairman, Animal Industry Group.

partments does not represent a complete report of all the work
performed during the year. It is based upon reports of the
heads of departments and typical pieces of interesting and im-
_ portant work have been selected as indicating the development
that is taking place and as recording data and observations less
formally than they may appear in scientific papers. Upon com-
pletion of important pieces of work, the results in detail and
their practis are published in bulletins issued from time to time
by the Experiment Station.
Soil Fertility- The maintenance of soil fertility is one of
‘ the most important problems with which farmers have to deal.
For many years past, the department of agronomy has con-
ducted soil experiment fields located in the principal soil areas
of the state, namely, at Lexington, Fayette County; Lone Oak,
McCracken County; Mayfield, Graves County; Russellville, - -
Logan County; Greenville, Muhlenberg County; Fariston, ~
Laurel County; Campbellsville, Taylor County; Berea, Madi-
son County; Lincoln Ridge, Shelby County.
On the Lexington field, a 4-year rotation of corn, soy-
beans, wheat and clover is followed on a part of the field on
which tests of various fertilizing materials are made. 'l`he re-
turns from thc several treatments are indicated i11 the following

The yield of corn under continuous culture shows some-
what similar results from the application of potash salts. In
these trials, the corn stalks are removed and no cover crop is _
used, which is in accordance with the plan of the old experi- _
ments. In the following table, the Grst column is an average
for the same three years in which corn was grown in the rota-
tion of corn and soybeans and is presented i11 order to show
the comparison between the crop grown continuously and corn
in rotation with soybeans, the same treatment being applied in
each case.
