les Typic Ustipsamments aux profondeurs supérieures et les Aquic Ustipsamments à la position intermédiaire. Les deux sols du domaine agricole font partie des Udifluventic Haplustepts avec de légères distinctions déterminées par un usage différent du sol et les origines des dépôts. Dans le parc citadin, les deux sols font partie eux aussi des Udifluventic Haplustepts mais, dans ce cas, l'interférence anthropique suggérée par l'abondance de fragments de briques sablées trouvés dans les profils est évidente.

Riassunto Nell’ambito del progetto PRIN 2007-2009 “Bilancio geochimico per la valutazione della qualità agro-ambientale in un sistema territoriale complesso: il caso di Ravenna”, sono stati caratterizzati da un punto di vista pedologico tredici profili: nove all’interno di una pineta litoranea, due all’interno di un’azienda agricola e due all’interno di un parco cittadino. I profili sono stati descritti, campionati ed analizzati al fine di generare un primo quadro conoscitivo della complessità pedologica delle aree di studio. All’interno della pineta i suoli risentono in maniera marcata della posizione topografica e della vicinanza all’acquifero superficiale. A profondità di falda elevate corrispondono dei Typic Ustipsamments, a profondità limitata dei Typic Psammaquents ed in posizione intermedia degli Aquic Ustipsamments. I due suoli dell’azienda agraria rientrano negli Udifluventic Haplustepts con leggere distinzioni determinate da diverso uso del suolo ed origine deposizionale. Nel parco cittadino i due suoli rientrano anch’essi negli Udifluventic Haplustepts ma in questo caso è evidente l’interferenza antropica suggerita dall’abbondanza di frammenti di laterizio rinvenuti nei profili. Keyword: : classificazione dei suoli; chimica del suolo Introduction The concepts of pedologic research and soil classification shall be correlated with paradigms depending on the soil quality. The knowledge of pedogenetic processes, the speed they occur at shall be monitored and studied in order to link a specific soil evolution with the concept of quality so as to choose indicators appropriate to soil pedon (MacEvan, 1997). Pedologic surveys are required in the case of studies dealing with soil utilization or environmental researches such as the one on soil sustainability for farming activities. The precision of data involving pedologic surveys is extremely important to take decisions as to the different research aspects (Webster and Oliver, 1990; Domburg et al., 1994). The concentration of trace elements in soils depends mainly on the type of bedrock and on pedogenetic processes developed on it. The influence of the lithological factor tends to decrease with soil development. The most important pedogenesis 116
aspects, linked with the destination of the potentially toxic elements (PTE) deal with chemical alteration processes of the bedrock and the eventual PTE release, and with the translocation and accumulation processes with iron oxides, clay and organic matter, controlled by several pedogenetic processes (Alloway, 1995). This work is aimed at characterizing and classifying soils belonging to three territorial situations of the Municipality of Ravenna, having different anthropic pressures, thus becoming preliminary and basic elements for additional surveys on the possible effects of potentially toxic elements. As a matter of fact sites taken into account have been the San Vitale Pinewood, a Site of Community Importance (SCI) concerned by subsidence and aquifer salinization phenomena, bordering to the South the petrochemical industrial pole connected with the activities of the harbour of Ravenna. The urban park inside the town, which is subjected to depositions due to vehicles traffic and the “Luigi Perdisa” extra-urban farm that accounts for the agricultural heart of Ravenna. Materials and methods Localization of the area examined. This study has taken into account the observation and monitoring a) of the San Vitale Pinewood soils, along two transects to the North and to the South of the area involved, traced out from West to East; b) of the soils belonging to the Luigi Perdisa farm, by opening a profile in an orchard and one in an arable cultivation; c) of the soils of Ravenna public park in which two profiles have been opened, depending on the distance to the main road (Fig. 1). Phytoclimatic features. The warm Mediterranean climate of the area is the typical climate of mild coastal environments, with about 600 mm of rainfall spread over the spring-autumn period and annual mean temperatures of about 13 °C. The San Vitale Pinewood is a protected area of about 1222 ha of surface within the “Parco del Delta del Po” (Park of the Po Delta) and represents a remnant of pinewoods where man has settled, on beach-ridge sands that deposited after the XII century. The Pinewood develops on a substrate made up of sand deposits (www.regione.emilia_romagna.it) stemming from sediments contributions of an old branch of the Po Delta (Veggiani, 1974; Bondesan et al., 1995). The duneinterdune system, which formed in 500 to 1000 years, has an almost parallel trend to the coastline. The vegetable component derives from the association of dry and wet environments where ashes (Fraxinus ornus and F. oxycarpa) and white poplars (Populus alba) alternate with umbrella pines (Pinus pinea), maritime pines (Pinus Pinaster) and oaks (Quercus robur), and the brushwood is rich in common hawthorn (Crataegus monogyna), ivy (Hedera helix) and dog rose (Rosa canina L.) (Piccoli et al., 1991). The area, boasting a remarkable environmental consideration, is subject to subsidence (Teatini et al., 2005) and aquifer salinization phenomena (Aquater, 1988; Ugolini, 1997; Giambastiani et al., 2007; Antonellini et al., 2008), owing to the 117
