Abstract

[Autom. eng. transl.] The present work aims to compare the ecological aspects derived from vegetation with the results of chemical-physical analyzes conducted on a soil of a degraded area. This area is represented by a former MSW landfill located on the outskirts of Piacenza (Emilia-Romagna, Italy). It is involved in a Life + project ("Environmental recovery of a degraded and desertified soil through a new soil reconstitution treatment technology" Life 10 ENV IT 400 "New Life"; http://www.lifeplusecosistemi.eu) which consists of in the experimentation of an innovative technology for restoring degraded and desertified soils. In the study area a vegetation analysis was carried out by performing 52 phytosociological surveys. In particular the ecological aspects of the vegetation cover were investigated using some indexes by Pignatti (2005) and Landolt et al. (2010) including H (humus index), R (reaction index) and U (humidity index). The results of the analysis have shown the presence of an indicator vegetation of medium-poor tenor in humus, neutral-basic and moderately dry soils. To characterize the covering soil, 52 samples were taken on which the basic chemical-physical analyzes were carried out, from which it emerged that it is neutral-basic, rich in carbonates and well-endowed in organic carbon. On 11 representative samples of the area, more detailed chemical-physical analyzes were performed to determine the available water of the soil. Through the use of pedofunctions the available water content of a hypothetical non-degraded soil was compared and compared with the real values of the 11 samples. From this comparison it emerged that the soil samples of the landfill have a lower available water content than the soil control although they contain more organic carbon. Generally high values of organic carbon correspond to high values of organic substance which acts by improving water permeability and availability. The scarcity of water available, together with the high organic carbon content, could be justified in a block of the humification processes and find confirmation in the low value returned by the index H.
