Particle Size Analysis of Soils Compared by Sodium Metaphosphate and Sodium Carbonate Dispersion Methods¹

ABSTRACT

Particle size data obtained by the Na₂CO₃-centrifuge method can be used for soils free of carbonates as a substitute for those obtained by the "standard" NaPO₃-pipette method. Dispersion by NaPO₃ and Na₂CO₃ boiling was essentially the same for 13 soil samples. Differences of a few percent clay were common between soil samples analyzed by the NaPO₃-pipette and Na₂CO₃-centrifuge methods.
