Procedures-Reference
Samples were air dried at less than 35° c. Clods were broke
up prior to grinding and sieving of samples. Large coarse
fragments were removed. Sample material was sieved.
Remaining rock coarse fragments left on the 10 mesh (2 mm)
sieved were 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.
