Développement de l’appareil végétatif et maturation du raisin sur quatre sols de Pomerol en 1995

Abstract

The Pomerol vineyard, located 35 km east of Bordeaux, covers around 800 ha on the left bank of the Isle.There is a system of fluvial terraces with more or less coarse gravel and pebble spreading, resting on a Tertiary substratum ranging from the Middle to Upper Eocene to the Lower Oligocene (Dubreuilh, 1993). This interweaving of terraces of varying thickness results in a brutal superposition of differentiated materials which give rise to various types of soil. Several site studies in this sector of the Libounais show significant morphological and analytical differences from one point to another (Guilloux et al., 1978; Duteau, 1982; Van Leeuwen et al., 1989). The distribution of the soils of the Pomerol vineyard was studied and resulted in a cartography at 1/25000th (Merouge, 1995). This typological variability of the soils led us to study in a comparative way the behavior of Merlot noir, the predominant grape variety in the region.
