ABSTRACT - Studies have shown that Eucalyptus spp.plantations develop a rapid and deep root system, reaching almost symmetrical relationships with the aerial part of the trees. In the present work, preliminary information on the deep root development ofE. grandisand its interaction with soils, saprolites and rocks in northwestern Uruguay was collected. Starting from a geo-logical base, three deep pits were made, which were classified according to a new saprolite proposal.
