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. Chemical and physical analyzes of the profiles, macroscopic descriptions of the roots in situ and microscopic observations (magnifying glass, electron microscopy and anatomical sections) of roots, saprolites and rocks were carried out. The deep root devel-opment was corroborated, showing varied and adapted roots that reach up to the rocks, observing indications of different root behaviors according to the different parts of the profile (soil, saprolite or rock). Finally, it is discussed how to focus future studiesof the deep root system of E. grandis., the characterization of the saprolite and rock based on this crop,and the possible effects on productive management and the environment.

RESUMEN - Estudios han demostrado que las plantaciones de Eucalyptus spp.desarrollan un rápido y profundo sistema radicular, alcanzando relaciones casi simétricas con la parte aérea de los árboles. En el presente trabajo se relevó información preliminar sobre el desarrollo radicular profundo de E. grandisy su interacción con suelos, saprolitos y rocas en el noroeste de Uruguay. Partiendo de una base geológica, se realizaron tres calicatas profundas, quese clasificaron según una nueva propuesta de saprolitos. Se realizaron análisis químicos y físicos de los perfiles, descripciones macroscópicas de las raíces in situy observaciones microscópicas (lupa, microscopia electrónica y cortes anatómicos) de raíces, saprolitos y rocas. El desarrollo radicular profundo fue corroborado, mostrando variadas y adaptadas raíces que alcanzan hasta las rocas, observándose indicios de comportamientos radiculares diferentes según las diferentes partes del perfil (suelo, saprolita o roca). Finalmente se discute cómo enfocar el estudio afuturo del sistema radicular profundo de E. grandis., la caracterización del saprolito y la roca en función de este cultivo,y los posibles efectos en el manejo productivo y en el ambiente.

ABSTRACT.
This study analyses variability and trends of atmospheric evaporative demand (AED) across Uruguay in the past four decades. Changes were assessed using pan evaporation measurements from 10 meteorological stations and compared to PenPan model calculations, which is a physically based model that employs meteorological data as input. Results demonstrate a high agreement between the observed AED and those estimated from the PenPan model. Both observations and model estimations agree on a high interannual variability in AED, though being statistically insignificant (p>0.05) at seasonal and annual scales. Given that AED shows high sensitivity to changes in relative humidity and sunshine duration, as a surrogate of solar radiation, the lack of significant trends in the AED observations and estimations over Uruguay can be linked to the insignificant trend found for these climate variables for the period from 1973 to 2014. This is the first study that reports Pan evaporation trends for this part of the world, helping to infill gaps for mid-latitude Southern Hemisphere areas, which are
poorly represented in Pan evaporation trends.
