Abstract:
The paper presents the catalogue of unproductive marginal lands affected by mining activities in the Jiu Valley, aspects regarding the quality of soil and biomass crops on experimental plots established in the living laboratory, the results obtained through anaerobic digestion of biomass and aspects regarding the use of digestate to improve soil fertility. The catalogue systematizes research related to unproductive lands in the Jiu Valley, the identification of pressures caused by inorganic soil pollution and the stationary mapping of tailings dumps. Based on the analyses performed on soil samples, experimental plots for soil remediation were established. The plot arrangement works, soil mobilization works for the establishment of biomass crops, their stability, as well as their maintenance and harvesting are highlighted. Also, aspects regarding the production of biogas obtained through anaerobic digestion of biomass cultivated on unproductive lands, in recipes from a mixture of sorghum, soybeans and corn in co-digestion with organic waste are presented. Qualitative and quantitative aspects of the obtained digestate are presented and the suitability of its use for improving soil fertility is analyzed. The paper presents working methods and hypotheses, data analysis and interpretation of the results obtained in the living laboratory set up for research on unproductive lands in the Jiu Valley.
