Abstract

[Autom. eng. transl.] The treatment of degraded soils through the reconstitution process (patented by the company mcm Ecosistemi) subjects the earthy matrices to mechanical disintegration and aggregation using additional materials of mineral and organic nature. This pedotecnica, which acts on the structure and composition of the soil, involves changes on the physical properties by acting on the structure and the state of aggregation of the soils. These changes, mainly due to the increase in organic matter, are also to be associated with the stability of the same and its redistribution within the mineral fraction of the soil, this occurs during the mechanical re-aggregation. Structure, state of aggregation, water retention capacity, are some of the physical properties of a soil, which, by describing the mechanical and hydraulic characteristics of the layer explored by the roots, determine its physical quality. Maintaining the physical quality of a soil, its improvement, are particularly important in relation to the increase in the phenomenon of soil degradation. The degradation and desertification are due to a worsening of the chemical and physical qualities of the soils, which, in this way, lose their functions within the ecosystem of which they do. The fight against soil degradation and strategies for the restoration of degraded areas are today the most important issues among those funded by research projects. The New Life project, co-financed by the European Union, aims to experiment, to test its effectiveness, with reconstitution as a pedotecnica to restore degraded soils. The experimental part of the project involved the creation and study of experimental plots prepared starting from different types of naturally degraded and reconstituted soils produced from these. The plots have been set up to compare the changes made by the reconstitution to the soils of origin over time. To this end, sampling has taken place every six months to carry out chemical and physical analyzes. The comparison values, measured two years after the treatment, between the soil of origin and the reconstituted soil, produced by it, of texture, apparent and real density, organic carbon content and quality of the structure according to Malquori and Ceccone (1962). Moreover, for both types of soil, with the help of texture and organic carbon data, the structural stability index (Pieri 1992) was calculated, which indicates the risk of structural degradation, ie the resilience of the soil structure. The comparison shows that the reconstructive process causes a decrease in apparent and real density, an increase in the organic carbon content, an improvement in quality and an increase in the resilience of the soil structure.
