Resumo: ABSTRACT: The Cerrado soils are acid with toxic levels of aluminum, being necessary to use lime to overcome these conditions to grow crops. The residual effect of lime in a Red Latosol were evaluated for corn at the 5th and 6th crop, under conventional tillage (disk plowing and harrowing) and no-tillage planting systems. Lime at different levels was previously applied for the first crop, with and without incorporation into the soil. The results showed a significant increase in corn grain production due to the residual effects of lime levels, either incorporated, surface applied with no incorporation, or a mixing of both methods. After six years of cropping, the surface applied lime with no incorporation changed the soil conditions mainly at the 0 cm - 10 cm soil depth. Below that depth, the soil pH and CEC base saturation were similar to those in the treatment with no lime application.
