Abstract: The production of conserved forages using an intense traffic of machinery under inadequate conditions of water content in the soil has caused soil compaction and the degradation of pastures. In order to face this serious problem it is necessary to know the potential of soil loosening by some forage plants. The objective of the present study was to evaluate the loosening of an Argisol cultivated with Tifton 85 grass, as well as its production. The experiment was conducted at the Federal University of Lavras, from February to June 2007, using a completely randomized design, cultivating the Tifton 85 grass under the following compaction degrees: 66, 83, 88, 92 and 98%. The physical attributes, the compressive behavior of soil and the production of dry mass of grass were evaluated. The loosening was quantified by the reduction of the preconsolidation pressure after cultivation. The bearing capacity models reflected the changes in soil macroporosity. Under study conditions, the Tifton 85 grass promoted the soil loosening proportional to the initial compression degree. The production of forage increased as the soil is loosened.
