Texture
Samples were air dried at less than 35° c. Clods were broke
up pdor to gdnding and sieving of samples. Large coarse
fragments were removed. Sample matedal was sieved.
Remaining rock coarse fragments left on the 10 mesh (2 mm)
sieved were removed. Remaining soil Gods left on the 10
mesh screen were ground until the sample just passed the
screen. Excessive grinding of sample matedal was avoided
dudng the entire sample preparation procedure.
