“…This result is in good accordance with the evidences reported by Crecchio et al (2004), about the same orchards, which recorded that the soil ATP contents, used either as a estimate of soil biomass size (Sparling and Eiland, 1983) or microbial activity (Fairbanks et al, 1984), were significantly affected by cropping system, being lower in IM soil than SM one. The remarkable ergosterol increment at third sampling time than the others two (Table 4) could be related to the variability of its content reported in natural soil environments (Newell 1992); nevertheless, it is known that the ergosterol content of fungal cells varies depending on species and environmental conditions (Tunlid and White, 1992).…”

At the same time, particularly, soil ATP contents rose significantly (Crecchio et al, 2004). This evidence is coherent with the rising of sterols (Table 4) which were negatively correlated with PMN (Table 5), confirming N immobilization by soil living organisms.…”

Several factors such as soil pollution and intensive agricultural management continuously damage the sustainability of agricultural production, with potentially adverse effects on soil quality. It is important to create applicable and valid soil quality indicators in order to both identify areas with potential productivity problems and monitor soil quality changes due to a range of perturbations. In this work we compared several chemical and biological variables between a Mediterranean soil characterized by intensive horticulture that has been irrigated for 20 years with moderately saline waters (IM) and an adjacent soil, subjected to a sustainable agricultural production management and irrigated with plain water (SM). Soil sampling was repeated three times during a year in both sites. IM soil had lower pH, organic carbon and total nitrogen compared to SM soil at all sampling times, while its electrical conductivity was significantly higher at two sampling times only. Potentially mineralizable nitrogen pointed out significant differences only at the first sampling time, with lower levels in the SM soil. β-sitosterol, cholesterol and ergosterol varied significantly with sampling time and were influenced also by management. Statistical approach by Principal Component Analysis highlighted a contrast between two groups of soil variables: potentially mineralizable nitrogen and sterols mainly weighted on the first axis, while chemical properties, weighted on the second one. Moreover, the second axis separated the soil subjected to a sustainable agricultural production system from that subjected to intensive practice management, while the first axis separated the third sampling data from the first two.

“…For this aim metabolic fingerprints of each microbial community were obtained using Biolog Ecoplates and then compared. The use of metabolic fingerprints from Biolog Ecoplates, that contain 31 different carbon substrates (see Table 1), has been previously revealed very helpful for the characterization of microbial communities from different environmental samples [9], [10]. Furthermore several studies have reported distinctive multivariate profiles of carbon source utilization among a variety of microbial community [11].…”

Abstract-The microbial ecology of cork oak rhizosphere was investigated using the Biolog Community Level Physiological Profile (CLPP) that provides a unique metabolic fingerprint helpful for the characterization of complex microbial communities. Microbial populations from the rhizosphere of cork oak plants growing at three different sites within the same area were characterized using CLPP and compared. The sites were distinguished by a different soil management under the tree cover and, in general terms, by a different anthropogenic impact. The comparison of metabolic fingerprints of the different microbial populations showed the existence of a relationship between general microbial activity and functional biodiversity in the rhizosphere and the level of anthropogenic impact. Particularly the presence of grazing animals, soil tillage and fire could be identified as the main factors affecting both the general microbial activity and the structure of microbial populations from cork oak rhizospheres.

“…Studies on microbiota diversity by molecular approach are increasing in this last years. In particular, studies were performed to evaluate the influence of soil type [9], the impact of a number of soil treatments, such as grassland restoration [10], saltrich water irrigation [11] or farm management style [12], on composition of telluric microbial community.…”

In this research, soil microbial structures under a wheat triennial monoculture and horse beanwheat-horse bean succession were evidenced using a metagenomic approach. Polymorphism analysis of DNA extracted from soil samples collected at the end of the third year of the two crop successions, was performed by PCR, carried-out with six different primers designed on simple tandem repeats sequences. Readable profiles were obtained with M13 primer, from which no polymorphisms were detected, and with the primer (GACA) 4 , that gave distinctive patterns. Experimental findings suggest that metagenomic analysis performed by (GACA) 4 primer may be an easy and suitable method to discriminate microbial diversity of different crop successions. (GACA) 4 PCR-pattern indicate that soil microbiota changes are well correlated with crop succession.
