Abstract
ABSTRACT Machinery traffic intensification has been recurrent in intensive agriculture in annual crops, which may lead to structural soil degradation and, consequently, a reduction of its productive capacity. Therefore, this study aimed to assess the influence of tractor traffic intensification on soil physical attributes and soybean yield components. The study was performed in an Oxisol under no-tillage for 10 years, using a randomized block design with five tractor traffic intensities (0, 2, 4, 6, 8, and 12 passes) and five replications. Density, porosity, macroporosity, microporosity, and penetration resistance were assessed in the soil and stem diameter, number of pods per plant, number of grains per pod, grain weight per plant, thousand-grain weight, and grain yield were assessed in the soybean crop. Tractor traffic intensification changed soil physical attributes, which were not limiting factors to soybean yield under the no-tillage system, providing higher stem diameter, number of pods per plant, grain weight per plant, and grain yield after 12 passes.

Summary
Soybean (Glycine max) is one of the main crops produced in different regions of Brazil. Compaction is reported as the main problem of structural soil degradation, changing its physical properties It changes soil pore space, reducing the macroporosity and total porosity and increasing density and soil penetration resistance (Bergamin et al, 2010; Valicheski et al, 2012; Valadão et al, 2015). Due to multiple factors involved in soil compaction under the no-tillage system, researches on the subject should be carried out to understand better its relationship with heavy machinery traffic under different soil and climate conditions and assist in carrying out appropriate management practices For this reason, this study aimed to assess the influence of tractor traffic intensification on soil physical attributes and soybean yield components
