The objective of this work was to investigate the spatial variability of attributes of eucalyptus (Eucalyptus urophylla S.T. Blake) and physical attributes of a Rhodic Eutrudox at Selvíria (MS). The study area has about 1.98 ha and samples of plant and soil were collected in a sampling grid containing 122 points: 84 points with regular spacing of 15 m and 38 points with regular spacing of 5 m. The following attributes of plant and soil were analyzed: perimeter at chest height, height of the plant, volume of wood, soil penetration resistance and soil moisture content. The attributes of the eucalyptus plants showed medium spatial variability, while the attributes of the soil showed medium and low variability. The exponential model was the most appropriate settings for the attributes of plant and soil studies. Simple linear correlation showed low correlation between the attributes of Eucalyptus urophylla and the soil physical attributes.
