This study aimed at evaluating the cone index, in depths of 0 to 0.3 m after mechanized harvesting of green sugarcane using the harvester Case A8800 and Case A4000 in the North-Fluminense region of Rio de Janeiro State. The results were analyzed using descriptive statistics, variance analysis, and Tukey test at 5% probability. The cone index shows that area 2 is more compact than area 1. In area 1, the subsoil layers are more compressed than the surface layer; while in area 2, different depths are equally compressed. Considering these results, this study recommends subsoiling in the two areas.
