Latosols (Oxisols) under cerrado vegetation have been intensively incorporated into the agricultural production process. However, studies involving soil quality in this environment are scarce. The objective of this work was to verify alterations on aggregation attribute indicators of soil quality, as a result of the management systems adopted for the native cerrado, and to select the best attributes indicating such alterations. The samples were collected at depths of 0-10, 10-20, and 20-40 cm from a typic Dystrophic Red Latosol (Oxisol) in Morrinhos, Goias State, Brazil. The following attributes were evaluated: mean geometric diameter (MGD), percentage of aggregates > 2 mm, percentage of aggregates 2 mm aggregate class (0.852*), and a negative correlation (-0.903**) with the 2 mm- and < 0.25 mm-aggregate groups were good indicators for alterations in relation to the native cerrado and can be suggested as useful components for the elaboration of a regional soil quality index.
