- Abstract:
- The particle-size composition is a basic soil physical property. Pipette method is a main traditional approch to analyze the soil particle-size composition while laser diffraction particle size analyzer is a new particle-size analysis instrument in recent years. The paper took 23 cinnamon soil samples with various clay particle contents to study the discrepancy between the two methods mentioned above. It shows that the results from laser diffraction particle size analyzer method are lower than pipette method when measuring the particle-size <0.002 mm while they have a good correlation with a determination coefficient of 0.97; when it comes to<0.02 mm particle-size, the results come close and have a strong correlation with a determination coefficient of 0.99; when measuring particle content<0.05 mm, they come very close with a determination coefficient of 0.91. The results from laser diffraction particle size analyzer can reflect the soil particle-size composition well if they get revised by a transformational model.
