Free-living nitrogen-fixing bacteria promote eco-engineering technosols ecosystem sustainability

Mined land rehabilitation faces a significant challenge in ensuring a sustainable N supply. Biological N fixation is the dominant pathway, contributing up to 97% of the soil N in natural terrestrial ecosystems. The functional ecology of free-living N fixation is often presenting a dominant biological N fixing pathway to acquiring newly available N in terrestrial ecosystems (e.g., Queensland tropical savanna forest). However, free-living N-fixing processes in mined land have received limited attention and understanding. This research aims to fill this knowledge gap by investigating the ecology and significance of free-living N-fixing organisms in mined land, specifically focusing on their N-fixing and adaption capacity to various mined land with advanced omics-based technologies. This will alllow development of technology to improve N supply in situ, promoting the long-term sustainability of mined land rehabilitation.
