Intensive soil cultivation in tropical and subtropical regions is only viable within the context of the sustainable agriculture that ensures appropriated technologies that assures productive efficiency without soil degradation. The present in situ study was carried out to determine the effect of the soil scarification in the saturated hydraulic conductivity in a dystrophic Red Latosol (Oxisol) under no-tillage systems for 20 years. The results showed that the study of hydraulic conductivity in the soil under no-tillage system was significantly affected in 1.45 10-5m s-1 after soil scarification, but a year later this gain was greatly reduced for 0.48 10-5m s-1.
