Soil compaction due to traffic of machines used in forestry sector causes structural changes on it, it can interfere with the bulk density, speed and water infiltration and root development of crops. The objective of this study was to evaluate the mechanical resistance to penetration in the Riacho Fundo watershade, Felixlândia-MG in an area belonging to a forest sector company located in the Cerrado miner. The penetration resistance tests were conducted in February 2011 in six plots with eucalyptus plantations located on plots 35, 36, 39, 40, 42 and 44, using an impact penetrometer. The plots showed average values of soil mechanical resistance above 4 MPa and these high values may be associated with the use of the soil before planting eucalyptus as pasture and also due to the condition of low soil moisture in the period to determine the mechanical resistance of the soil.
