EVOLUTION OF PHYSICOCHEMICAL AND BIOLOGICAL PROPERTIES OF SOILS AFFECTED BY CONSTRUCTION WORKS OF THE FLOWLINE

In this study physical and chemical properties, and microbiological profiling of agricultural and forest soils were determined to assess the dynamics of environmental restoration processes occurred after an oil pipeline implantation. Soils were sampled ante-opera, to be used as control, and during the subsequent years. Agricultural and forest soils showed an interesting diversification of several parameters in each sampling site, with significant changes of textural fractions, high values of pH, and a remarkable bio-stimulation of germination, and a strong enrichment of edaphic fauna. A high microbial diversity was also ascertained, stressing the soil capacity to tolerate and withstand the disturbance due to the pipeline installation, with the presence of bacterial species able to perform certain functions in altered conditions
