The classification into soil fractions found in the new Polish Standard PN-R-04033 is fully comparable- with the international classifications (FAO/USDA) in question. The following diameters were adopted as the main groups of soil fractions: stones >75 mm, gravel 75-2 mm, sand 2.0-0.05 mm, silt 0.05-0.002 mm and clay <0.002 mm. On the other hand, soil fractions classification according to the Polish Soil Science Society (PTG), including so-called fine particles (<0.02 mm), is not compatible with both the new Polish Standard and the discussed international classifications. This also refers lo the classification into textural groups according to PTG. However, the classification into textural groups according lo Polish Standard is quite similar to international classifications.
