Soil compaction due to agricultural machinery traffic is a threat to soil productivity and soil ecological functions. The prediction of soil stresses and compaction that soil bear during the harvest and transport are fundamental indications in the prevention strategies and remediation of the soil compaction. The objective of this research was to predict soil compaction caused by harvesters and transport equipment during sugarcane harvest on soft soil. Machinery traffic was simulated using the TASC V3.0 model, Module 1 "Stress Propagation and Soil Damage" was used. The machine system used for harvest sugarcane were formed by harvesters CASE IH 8800, and tipping tows 7CX (SC)-10 pulling by tractors YTO 1608 or XTZ 150K-09. Parameters from machinery and soil are introducing as data. The use of modelling TASC V3.0 permitted to predict soil compaction caused by harvesters and transport equipment during sugarcane harvest on soft soil. More severe soil compaction was obtained during use of tipping tow 7CX (SC)-10 due to high mean contact pressure and high tire load, which caused severe soil compaction until a depth of 0.37 m. Rear tire of tractor YTO 1604 caused severe soil compaction too reaching 0.31 m of depth. In general sense all equipment caused severe soil compaction in tillage layer, therefore must be make decompactions works with the objective to loose soil in depth for a good developed of sugarcane ratoons.

Keywords : Mean Contact Pressure; Soft Clay Soil; TASC V3.0.
