Summary

The objective of this work was to evaluate the relationship between soil micromorphological and physical attributes in an Oxisol (Rhodic Eutrudox) under sugarcane. Soil samples were collected at the intersection points of a regular grid, with 10 m intervals, comprising a total of 100 points, in the horizons A1 and AB. The higher values for bulk density, microporosity and soil penetration resistance and lower values for macroporosity, total porosity and saturated hydraulic conductivity mainly in the AB horizon, indicated compaction in this horizon, confirmed by image analysis (micromorphology).
