CHEMISTRY
· BY A. M. PETER
The work of the department has been along the same lines
as heretofore, being principally in relation to soil problems,
but has, as usual, included much of a miscellaneous character.
Quantitative analyses of 49 samples of soil, from 12 coun- A
ties, have been completed and work is under way on 64 samples
from Shelby County, taken in connection with the soil survey
of that county, made in eo-operation with the Bureau of Soils.
Mr. Avcritt was in the field most of the summer, in connection
with this survey. Qualitative tests have been made upon 151
samples of soil from 43 counties and suggestions have been given
the senders as to the desirability of using phosphate and lime-
stone, or other treatments, upon their land.
Determinations of lime, or of lime and magnesia, have
been made in 379 samples of limestone, from 52 counties, and
recommendations given as to the suitability of the materials
for agricultural use.
Further studies on the composition of lime-sulfur solution
were made and reported upon in two scientific papers.
Co-operative work for the referee on insecticides and
fungicides of the Association of Official Agricultural Chemists
_ was engaged in.
Sixty-six analyses of coals and other minerals were made
- for the Kentucky Geological Survey.
Scventy—four samples of water, from 34 counties, were ex-
.a1nined.
Numerous analyses or examinations were made of various
materials sent in by farmers and others, making a total of 816
samples, including the foregoing, analyzed or examined in the
department this year.
