Recommendations for soil sample preparation, pretreatment, and data conversion for texture classification in laser diffraction particle size analysis
Geoderma(2023)
Abstract
•Pedotransfer function for recalculation of PSD from LDM into SPM was validated.•Pedotransfer function was validated on an independent database.•74% accuracy in converting LDM to SPM results was achieved.•Air dry soil samples are recommended for PSD measurements.•Ultrasound disaggregation is recommended for PSD measurements using LDM.
