Soil Depth (mm) Soil Depth (mm) in the region 100-300 mm, below this area there is a reduction indicating that the compacting vehicle traffic causes damage primarily in the layers between 100 and 300 mm. It is noted in Table 3 that the PZ zone had the highest coefficient of variation between 25.9 to 65.2%, indicating that less intensive traffic promoted an uneven structure on the ground. In TPSD zone was observed lower coefficients of variation. This may indicate a negative factor that traffic more intensive machinery promoted greater uniformity in the soil structure, reflected by higher compaction.

4. Conclusions It can be concluded that the semi-mechanized planting of sugar cane in the system currently used in Brazil causes soil compaction, especially in the “Truck seedcane path for distribution zones” (TPSD zone) which there is an intense and uncontrolled traffic of machines and agricultural implements in the cultivation area, which may reflect directly on the productivity and longevity of sugar cane plantation. 5.
