. 6 Thirty-ninth, Annual Report
    Noteworthy progress has been made in studies of the
l I i V pathology of sterility in mares, mosaic and frenching of plants,
_ I     the effect of the rarer elements on plant growth and soil im-
I Q provemcnt. The findings of the Experiment Station continue
i to be increasingly used by the farmers of the state, as is evi-
_ Q   denced by correspondence, personal calls and requests for
i   bulletins. _ _
,   Economic studies of agriculture have been greatly en- ·
. _   larged during the past two years. Much material is being V
S   accumulated and published which should be of aid to the
      farmer in meeting the larger economic problems confronting
i V     him. Interest in these particular studies is marked and show-
= i _   ing a steady increase. However, the adoption of methods and
I     practices indicated by the results of these studies is not rapid,
· I _     but is in about the same proportion as the adoption of improved
.     methods applying to production. `
I I     The Experiment Station continues to give much attention
v J · I · -,_, to the study of soil problems in the state. An examination of
    · the various economic studies or of the condition of agriculture
l   _     _ in the state serves to convince the student of the outstanding
    i need of a sound soil policy on the part of landowners. Irre-
_ ·     · spective of probable prices, markets and labor supply, the need
. i of a productive soil is imperative. Kentucky must have larger
L , s ‘   { ' areas on which the soil is properly maintained before it may
{   ·_       have the agricultural incomes which natural conditions justify.

L `   _.   field of research and the application of its results, that there
  ,_ if     { _ may be a sound foundation upon which to construct a progres-
{ ,       sive and prosperous ag1·ieulture.
  ii   The addition of one hundred and three acres to the lands
   *3 of the Experiment Station, authorized by the last legislature,
5   is  has been most helpful, not only in consolidating its holdings,
  V       but in providing opportunity for the necessary growth of its _
      work. The agricultural land available at the substations, at
lg}, ·»i_'     seven soil experiment fields and at the Experiment Station, is
    typical of the principal soil areas of the state, and enables a
    direct application of experimental evidence to each agricultural
