The purpose of the study was to investigate the total phosphorus content in granulometric fractions isolated from the genetic horizons of arable Cambisol developed from morainic loams of the Middle-Polish (Riss) Glaciation, Wartanian Stadial (central Poland). Isolation of granulometric fractions was achieved with application of the Atterberg method without the use of centrifuging and dispersing agents. The total phosphorus content in granulometric fractions increased with a decreasing fraction diameter, and its average content (in mg kg-1) and contribution in particular fractions (in %) was: 1-0.5 mm – 120 (1.1%), 0.5-0.25 mm – 72 (0.6%), 0.25-0.1 mm – 62 (0.5%), 0.1-0.05 mm – 276 (2.5%), 0.05-0.02 mm – 317 (2.8%), 0.02-0.01 mm – 396 (3.5%), 0.01-0.005 mm – 807 (7.2%), 0.005-0.002 mm – 3590 (32.2%), and fraction
