Control the machinery traffic through autopilot and use the combined spacing of two rows are possible solutions to mitigate soil compaction problems. The objective of this study was to evaluate traffic control using autopilot in order to soften the problem of soil compaction in mechanically-harvested sugarcane areas. The study was conducted in two experimental areas belonging to Usina Santa Fe, in New Europe, São Paulo, Brazil. The design was a randomized block design, with 3 treatments: T1 = sugarcane planted in single spacing and without autopilot (1.50 m); T2 = sugarcane planted in single line spacing and managed on autopilot; T3 = sugarcane planted under combined spacing of two rows (1.50 × 0.90 m) and managed with autopilot, with 4 replications. Was collected samples in the wheel row (WR) and the seedbed (SB), which was located next to the plant row to, in layers from 0.00 to 0.15 and 0.15-0.30 m. It was observed that the seed bed area showed higher porosity in the treatments with autopilot in the second year of evaluation. There were no differences in pore sizes and shapes between the treatments in the two years studied. The large and complex pores were observed to be reduced in the second evaluation year.

Findings are inconsistent both across primary studies and previous meta-analyses. This study ...
