Sample Preparation Samples were air dried at less than 35°C. Clods
were broken up prior to grinding and sieving the
sample. Large rock fragments were removed.
Sample material was sieved. Remaining rock
fragments left an the 10 mesh (2 mm) sieve Here
removed. Remaining soil clods left on the 10 mesh
screen were ground until the sample just passed
the screen. Excessive grinding of sample material
was avoided during the entire sample preparation
procedure.
