Abstract

[Autom. eng. transl.] The construction of transport infrastructures is often the cause of degradation and fragmentation of ecosystems directly or indirectly affected by the construction of the work, with effects also on the quality of the soil, which is altered in its physical and chemical properties. The recovery interventions of these sites, foreseen by the national legislation and aiming to accelerate the process of colonization of the potential forest vegetation, are often ineffective precisely because of the degradation of the soil. The correct restoration of the pedological component involves high and sometimes unsustainable costs, both economically and ethically. The mcm Ecosistemi company has patented a technology that is based on chemical-mechanical processes applied to a mixture composed of a degraded soil and / or an assimilable mineral matrix and of industrial processing waste products, for the realization of a soil called tecnosuolo reconstituted. This soil makes it possible to avoid the removal of fertile soil from other sites and to use waste material otherwise destined for landfill, producing a non-renewable resource and responding to the concept of a circular economy. In order to evaluate the effectiveness of the use of reconstituted soil in environmental recovery interventions by planting forest species, an open field trial was performed. The degree of rooting and growth rates of the plants were evaluated in 3 types of reconstituted soil, with different texture, and in a control soil, improved with compost. A trial in a controlled environment was also conducted, where the development of the seedlings was monitored in different humidity conditions of the technosole. At the end of the first vegetative season the results of the experimentation in the field showed how the reconstituted soil represents a valid substrate for rooting and for the growth of the seedlings (average vitality> 70% as in the control and average growths of about 51 cm against the 44 cm of the control). Even the experiments conducted in the cell have shown the effectiveness of the technosol in favoring the growth of forest species, thanks to its ability to retain and make available the water resource. Although it is necessary to carry out medium-long term monitoring to evaluate in the most effective way the evolution of the physico-chemical properties of this soil and its effect on forest species, the preliminary results obtained seem to suggest how the use of the reconstituted soil can represent a valid solution to be applied in environmental restoration interventions in degraded lowland areas.
