Abstract:The aim of this paper is to determine the difference between two methods for determination of granulometric composition of the soil, classical International B (documented) and Standard ISO 11277:2009(E) (modified) method. For the analysis, 8 samples from different soil types were analyzed in 7 repetitions in order to compare results. All samples are from the surface horizons. The main differences between these two modified methods are the medium containing the cylinders with samples (air and water), the pipetting time, the number of pipetting and the pipette volume. With the statistical processing of the results, it can be concluded that there is no statistically significant difference in the measurement of fine sand in both methods, however that there is a difference in the measurement of silt and clay. From eight soil analyzes in both methods, four same texture classes were obtained. The obtained results indicate that there is a need for further research or comparison of methods, on a number of samples and on the soil of different textures and different content of organic matter.
