sample is then weighed and sieved through a 0,425 mm sieve. It is desirable to place a 2.00 mm or a 4,75 mm sieve above the 0,425 mm sieve to act as a guard for the finer sieve. The material retained on the 0,425 mm sieve is transferred to a mortar and by rubbing with a rubber-tipped pestle, most of the soil aggregations are disintegrated
