▼ The study presented here investigates the use of a mixture consisting mainly of pyrolusite by-products (MnO2) used as substrate in a limestone quarry restoration. Over a period of 3,5 years, the development of biological activity and the establishment and growth of vegetation was monitored. The substrate mixture consisted of 70% by-products from pyrolusite (MnO2) electrolytic process, 10% sand (to improve the physical properties), 10% soil (to supply the mixture with microorganisms) and 10% rice husk (to improve the mixture properties). Three plant species were used: pine (Pinus brutia), cypress (Cupressus sempervirens) and broom (Spartium junceum) and two types of fertilization were applied. At first, a laboratory experiment was conducted to study the chemical composition and decomposition rates of the rice husk in different mixtures of pyrolusite by-products and soil. The rice husk decomposition rates were lower in the pyrolusite mixture (3,04%) than in the soil (5,03%). The quarry substrate was analyzed every six months for microbial biomass, respiration activity, and alkaline and acid phosphate activities. From the data obtained substrate quality indicators were estimated, namely the microbial quotient, metabolic quotient and mineralization quotient. In addition, the physiochemical substrate properties were also estimated, such as aggregate stability, moisture content, organic carbon, pH, available P, nitrate and ammonium nitrogen, exchangeable cations (K+, Na+, Ca+2, Mg+2), cation exchange capacity, trace elements Fe, Mn, Cu and Zn and content of Fe and Mn oxides. In the selected plants, heights and mortality rate per year were used as growth indicators. The biomass and tissues nutrient analysis of native plants was also measured during the final year of experimentation. Data analyses suggest, that the establishment of the selected plant species at the experimental substrate was successful showing acceptable mortality rates (20-25%). Planting the selected species affected the substrate biological properties, i.e. increased activity at the rhizosphere in time (compared to the beginning of the experiment) and space (the rest of the substrate). The values of microbial biomass, CO2-C release from basal and total respiration and alkaline and acid phosphatase activity of the control were 85,84 μg Cmic g-1, 78,8 μg CO2-C g-1 d-1, 381,2 Σμg CO2-C g-1, 108,21 and 92,43 μg p-nitrophenol g-1 h-1, respectively. Similarly, the results in the third year under the cypress trees were for the microbial biomass 214,94 μg μg Cmic g-1, the CO2-C release from basal respiration 112,8 μg CO2-C g-1 d-1 and total respiration 679,4 Σμg CO2-C g-1, while in the rest of the substrate the values of these properties were 69,53 μg Cmic g-1, 74,4 μg CO2-C g-1 d-1 και 353,1 Σμg CO2-C g-1, respectively. The alkaline and acid phosphatase activities under pine trees were 198,92 and 125,06 μg p-nitrophenol g-1 h-1, respectively and in the rest of the substrate were 138,76 and 71,29 μg p-nitrophenol g-1 h-1, respectively. The moisture content of the…
