Description:	Saturated field hydraulic conductivity was measured, using a guelph permeameter, at depths of 10,20 and 60cm, to verify the effects of intensivelly managed, compared to extensively managed ones soils (Hapludox eutrodox, paleudalf), in Sao Carlos, SP, Brazil, under tropical altitude climate. Significant differences accurred within depths (P<0.05). Hower, differences decreased with yars and, therefore, differences among soils and between managenebt systems were also reduced. Highest mean conductivity values occurred at 60-cm depth and at the extensively managed paleudalf shoed higd resistance to reduction of conductivity at 10 cm depth. A general year effect appered claiming for more studies on this matter.
