Excerpt from Methods of Soil Analysis for Soil-Fertility Investigations

In some soils it is rather difficult to discriminate between the weathered rock and the soil; here the operator must use his own judg ment. Pick out and set aside any gravel, iron concretions, or rocks that may be present and combine later with the material that does not pass ythrough the 2 mm. Sieve. Repeat this process of crushing and sieving until only the primary particles and organic residues re main On the sieve. This coarse material may be discarded.

Mix well the soil material passing the2 2-mm. Sieve and store in an airtight container. This constitutes the stock sample on which all the determinations here described are made.
