Particle Size Distribution of Various Soil Materials Measured by Laser Diffraction—The Problem of Reproducibility

Abstract: Particle size distribution is an important soil parameter—therefore precise measurement of this characteristic is essential. The application of the widely used laser diffraction method for soil analysis continues to be a subject of debate. The precision of this method, proven on homogeneous samples, has been implicitly extended to soil analyses, but this has not been sufficiently well confirmed in the literature thus far. The aim of this study is to supplement the information available on the precision of the … Show more

“…The highest average CV and therefore the lowest reproducibility for both classification systems were found for the sand, silt, and clay fraction of the Bs horizon and for the sand and clay fraction of pretreated samples of the Bsw and BwC horizons (Table 3). Thus, the lower the sand content (Table 2), the lower the reproducibility as also found by Polakowski et al (2021). In our study, the texture classes of the four horizons are very limited (silty, sandy loam) and the previous statements is consistent for the present study.…”

“…The reproducibility of LDM measurements was determined by the coefficient of variation (CV). As the ratio of the standard deviation to the average (%), the lower the CV value, the higher is the reproducibility (e.g., Bieganowski et al, 2018;Polakowski et al, 2021).…”
