Abiotic legacies mediate plant-soil feedback during early vegetation succession on rare earth element mine tailings

An increasing number of studies have shown how feedback interactions between plants and soil can influence primary and secondary succession. However, very little is known about the patterns and mechanisms of such plant-soil feedbacks on stressed mine tailings ecosystem, which can be severely contaminated by a range of toxic elements. 
In a two-phase plant-soil feedback experiment based on the rare earth element (REE) mine tailing soil, we investigated biotic (changes in bacterial and fungal community) and abiotic legacies (changes in chemical properties) of three pioneer grass species, and examined feedback effects of three grasses, two legumes and two woody plants with different root traits.
Positive plant-soil feedback was found in Miscanthus sinensis, Paspalum thunbergii and Tephrosia candida, and neutral feedback was observed in other four plants. These effects corresponded with an increase of nutrients and total organic carbon, as well as a decrease of acidity and extractable alumi..., In a two-phase plant-soil feedback experiment based on the rare earth element (REE) mine tailing soil, we investigated biotic (changes in bacterial and fungal community) and abiotic legacies (changes in chemical properties) of three pioneer grass species, and examined feedback effects of three grasses, two legumes and two woody plants with different root traits. 
The soils for the experiment were collected from several patches of REE mine tailings that had been abandoned since 2007. The grass species, comprising M. sinensis, Paspalum thunbergii and Digitaria sanguinalis, were planted in both the conditioning and feedback phases.Besides grasses, the legume species, comprising of Tephrosia candida and Cajanus cajan, and the woody species, comprising of P. massoniana and C. lanceolate, were planted in the feedback phase. 
The conditioning phase lasted for 18 weeks. At the end of this phase, the shoots and coarse roots were removed, soil samples were collected for chemical properties (abiot..., , # Abiotic legacies mediate plant-soil feedback during early vegetation succession on rare earth element mine tailings

These datasets are derived from a two-phase plant-soil feedback experiment based on the rare earth element (REE) mine tailing. We investigated biotic (changes in bacterial and fungal community) and abiotic legacies (changes in chemical properties) of three pioneer grass species, and examined feedback effects to three grasses, two legumes and two woody plants with different root traits.
