ABSTRACT
A study was conducted to determine the vertical distribution of Eucalyptus globulus ssp. maidenii fine root (with diameters of up to 2 mm) density to a depth of 0,5 m and their relationships with soil properties. Roots were sampled near the stem of 10 trees with the soil corer method. Fine root distribution is influenced by soil physical and chemical properties. A very high density of fine roots was found at 20 cm depht, while a low density was observed in the clayey horizon. Fine root density (DRF) correlated positively with organic C and extractable P and negatively with soil bulk density.
Key words:
fine root; Eucalyptus globulus ssp. maidenii; soil properties.
