SUMMARY OF SOIL TEST RESULTS
(July 1, 1954 June 30, 1955)

Herman L, Breland
Asst. Soils Chemist


The Soil TeStitg Laboratory analyzed a total of 9,608
ing the year for an average of 800 samples per month. The
smallest number of samples received were for the months of
November, respectively.


samples dur-
largest and
March and


Although 9,608 samples were received by the laboratory, only 54.6
percent were service or extension type samples. The remaining 45.L per-
cent were for various research projects being carried on by personnel
of the Agricultural Experiment Station. Of the 5,246 service samples
received, only 3,863, or about 73.6 percent, were soil samples with suf-
ficient information to be included in this summary.

The number of samples received and the number of determinations made
by months are given in the following table:

The 15 samples having no information about them except the labora-
tory data were removed for all other calculations, making the total
number of samples 3,861. The table shows that samples were received
from all but 6 of the 67 counties. The six counties not sending samples
in for analysis were Charlotte, Glades, Hardee, Monroe, Okeechobee and
St. Lucie.

When all the pH values were grouped into the five pH ranges, regard-
less of crop or soil area, the following distribution was found:

The pH and nutrient levels as related to crops and soil areas are
given in the following tables. The data from all the samples were group-
ed according to (1) crops being grown and (2) the general soil areas of
the state. The pH and nutrient levels, as found by soil tests, are then
given for each of the above categories.
