Abstract

This intervention partially deals with the data obtained within a research project supported by the "NATO Science-for-Peace" program ESP.Md.SFPP 981674, and undertaken by an interdisciplinary consortium of research teams involving three Nato countries and two Mediterranean Dialogue countries. The soil of unmanaged cork oak forests located both in Sardinia and in Tunisia was characterized. The studied Sardinia area was a stand of about 1 ha (40°54'48"N,9°08'00"E, left unmanaged for about 50 years and located in Cusseddu-Miali-Parapinta, in the Northern part of the island in Tempio Pausania District. This forest is run by Agris Sardegna and certified since 2005 according to the FSC Standards (SA FM/COC-001436). The studied Tunisian area was the cork oak forest located in the site of Ras Rajel (36°57'15""N,8°51'48"E), in the North-Western part of Tunisia. Soil samples were collected in both areas at the depth of 0-10 cm, according to international standards (ISO 10381-1:2002) to determine the pedological characters (humidity, pH, total organic carbon, total nitrogen content and texture) and the fungi community. The data were tested for significance with analysis of variance (ANOVA) techniques. The soil of the two studied areas were significantly different as far as pH, TOC% and Sand content are concerned. In Sardinia soil the pH values ranged from 5.15 to 6.14, TOC from 4 to 9% and total N from 0.25 to 0.39%. In Tunisia soil the pH values ranged from 6.22 to 7.38, TOC from 3 to 6% and Total N from 0.20 to 0,43%. The texture of Sardinia soil was mainly classified as "sandy-loam" and the Tunisian ones as "sandy-clay-loam" (USDA classification system). As far as the fungi community is concerned in Sardinia soil, the most frequent fungi genere were Trichoderma (18%), Penicillium (15%), and Paecilomyces (13%). in Tunisian soil Penicillium was the dominant genus (54%), and Aspergillus was occurred second n the order of dominance (20%).
