PARAMETERS AND ANALYTICAL PROCEDURES UTILIZED FOR TOPSOIL ANALYSIS
Parameter-UniLt
Sample Preparation
Procetlures-Reference
Samples were air tlrietl at less than 35° c. Clods were Woke up poor to
grinding and sieving of samples. Large coarse fragments were removed.
Sample material was sieved. Remainirg rodr coarse fargments leR on the
10 mesh (2 mm) sieved were removetl. Remaining soil datls left on the 10
mesh screen were ground urrol the sample just passed the saeen.
6tcessive grind ing of sampl a material was avoided during m e endre sample
prepareson procedure.

Physical and, where possible, chemical properties of each horizon within the sampled profile were
described and recorded in the Feld on standard SCS "232" soil description forms. These properties
