Evaluation of ash derived from conversion of contaminated Miscanthus x giganteus biomass as a soil amendment: impacts on soil parameters and physiological characteristics of Zea mays L.

Popis výsledku v původním jazyce

Biomass ash (BA) is a sustainable soil amendment with the potential to reduce dependency onchemical fertilizers, enhance soil quality, and improve crop productivity, in accordance with theprinciples of the circular economy. This study evaluated the effects of Miscanthus x giganteus(Mxg) ash, derived from biomass grown on trace element (TE) contaminated land in France,applied at rates ranging from 0 % to 7 %, on soil properties, nutrient dynamics, and the physiological responses of the test plant, Zea mays L. The study results demonstrated that BA application significantly increased soil pH (from 6.2 to 7.5) and electrical conductivity (from 0.42 to2.14 dS m? 1), indicating enhanced buffering capacity and ion-exchange potential. The soilorganic carbon content reached a maximum of 3.8 % with a 5 % ash application rate, suggestingits potential for carbon sequestration. Nutrient analysis revealed a substantial increase in Kconcentration, reaching 51,691 mg kg? 1 in the plant leaves at the 7 % BA level, while Mg and Pconcentrations decreased to 826 and 567 mg kg? 1, respectively, at the same dose. A higher ashapplication rate (7 %) caused physiological stress and nutrient imbalances, thereby limiting thegrowth of Z. mays plants. These findings highlight the dual effects of BA as a soil amendment:while lower application rates (1 % and 3 %) improve soil fertility and plant growth, higher doses(5 % and 7 %) pose potential risks. Given the large-scale availability of Mxg BA from the thermalconversion of biomass cultivated on TE-phytoremediated sites, these results support its practicaluse in sustainable agriculture and land reclamation, provided that application rates are carefullyoptimized to balance benefits and risks.
