L'incremento della sostenibilità ambientale attraverso la diminuzione del rischio erosivo.
2014
Riassunto: Lo scopo di questo lavoro è quello di mettere a punto, a partire dalle informazioni territoriali quali caratteristiche meteorologiche e pedologiche,uno studio capace di evidenziare la sostenibilità della gestione attuale di due ipoteticheparcelle sperimentali individuate nel territorio del sottobacino Iudeo-Bucari (Trapani). Si tratta di due vigneti che rappresentano per caratteristiche morfologiche e gestionali la collina del sottobacino ovvero una delle aree maggiormente vitate della Sicilia. Il fine è valutare la sostenibilità della gestione del suolo in termini di controllo dell’erosione (perdita di suolo), attraversol'applicazione del modello USLE (Universal Soil Loss Equati…
Distribution patterns of fungi and bacteria in saline soils
2014
Saline soils are environments characterized by uneven temporal and spatial water distribution and localized high concentrations of salts. Spatial distribution patterns of fungi and bacteria in saline soils, and the link between microbial community dynamics and salts accumulation are critical issues throughout the world (Ettema, Wardle 2002). This study was focused on spatial distribution patterns of soil fungi and bacteria in a saline soil located in Piana del Signore (Gela, Italy) where some ecological variables acted as shaping factors in aboveground and belowground communities distribution. Bacterial, archaeal, and fungal communities diversity and distribution in ten soil sites (A horizo…

The cork oak in the Mountains of Palermo (Italy): ecological insights from the south-eastern edge of its distribution range
2020
Abstract: The uneven presence of the cork oak (Quercus suber L.) within its distribution range is not only determined by its climatic requirements but also by specific edaphic needs. Although most of the natural populations thrive in acidic soils deriving from metamorphic or volcanic rock outcrops, some cork oak populations are found growing in soils deriving from calcareous bedrock, which are considered less suitable. We carried out a multidisciplinary investigation at the south eastern edge of the Q. suber distribution range (Mountains of Palermo, NW Sicily), including soil, floristic, and vegetation surveys, aimed at: (i) assessing the native or introduced origin of some peculiar cork oa…

The “Soil Genetic Erosion”: a new threat for soils?
2015
During the 1990’s the concept of pedodiversity started to be diffused in the scientific literature and the decrement of the soil diversity in space and time - particularly due to human activity - has been seen as a sort of underhand problem affecting soil ecosystems, considering that different soil types face gradual or drastic reduction or complete loss of their unique “genetic features”. Pedodiversity has received considerable recent interest, especially as peculiar aspect of biodiversity and has been assessed by several authors by applying diversity indices used in ecology. This paper takes into consideration the influence of human activities on the loss of pedodiversity in a Mediterrane…
Pedodiversity
2013
In Chap. 6, dealing with pedodiversity of Italy, Edoardo A. C. Costantini, Roberto Barbetti, Maria Fantappie` , Giovanni L’Abate, Romina Lorenzetti, and Simona Magini illustrate the distribution of soil classes, mainly by means of maps. Soil regions on hills are the most lithologically and climatically variable environments, and host the greatest soil variability and endemisms. A vast majority of the WRB reference soil groups (25 out of 32), as well as soil orders of Soil Taxonomy (10 out of 12) are represented in the main Italian soil typological units (STUs), but the clear skewness and lognormal distribution of STUs demonstrate the utmost endemic nature of many Italian soils. In particula…
An extra-urban soil cadastre for Italy: a first guide for the introduction of soil information
2020
Assuming a positive outcome of the parliamentary procedure for laws and, thus, the transformation of the official cadastre for buildings and land into a soil cadastre (urban, extra-urban and cadastre for the conservation of natural or semi-natural soil diversity) would start a new era for pedology. Finally, after many decades of activity to expand soil culture in Italy, almost all Italian families would be in contact with a soil specialist. Land use and redefined plots would be handled with greater care and responsibility. Experts in agricultural and forestry and biodiversity conservation would have a new impetus in their activity. Furthermore, economists will also have to address new issue…
Soil Knowledge
2016
Soil being a crypt-resource, that is a hidden resource, it is considered entirely important only when environmental disasters happen. Therefore, it would be necessary to change the paradigm that ties the man to the soil, trying to consider it as a known resource to be managed and protected always and everywhere. The soil should not be manipulated, but it should be managed. To achieve this aim, we need to know it completely. An initial identikit includes salient features that historically the men always looked at: a good depth, a balanced texture, a reaction of the soil tending to neutral, a good stiffness, a good level of organic matter and elements of fertility.
