dc.descriptionAgricultural management affects soil structure, modifying soil physical properties and soil water movement. The objective of this study was to evaluate the effects of no-tillage (NT) and conventional tillage (CT) on soil structure through physical properties and pore distribution in 2-D digital images. The study was conducted in an Oxisol with a randomized block design. Soil bulk density, soil macroporosity, mean weighted diameter (MWD), saturated hydraulic conductivity (SHC), and analysis of 2-D digital images (156.25 mu m(2) resolution) were evaluated at the depths of 0-0.20 and 0.20-0.40 m. Management systems did not differ for soil bulk density and soil macroporosity. The NT showed higher MWD and SHC compared to CT. The CT had a greater total pore area at the 0-0.20 m depth in relation to NT, with the opposite occurring at the 0.20-0.40 m depth. The NT had a greater number of complex pores of large size (>0.156 mm(2)) at the depth of 0.20-0.40 m in relation to the CT, which showed a predominance of rounded pores. The NT showed improvements in soil structure in relation to the CT, with greater aggregate stability, hydraulic conductivity, and total pore area, contributing to soil and water conservation in production systems.
