    • Quantification of Bouteloua curtipendula biomass, organic matter accumulation, and geochemical changes during growth in mining wastes

    Metadata Updated: July 6, 2024

    Re-vegetation of mining wastes is difficult due to the inhospitable conditions for plant growth. Our aim was to determine whether the combined addition of municipal waste compost and plant growth promoting endophytes (i.e., microorganisms that live within plants) could improve plant growth, organic matter accumulation, and phytostabilization of metal contaminants across multiple types of hard rock mine waste. We grew a widespread perennial grass, Bouteloua curtipendula, for 45 days in tailings (Ag-Pb-Au mine) and waste rock (porphyry copper mine) sourced from southeastern Arizona, USA. We quantified organic matter accumulation, microbial biomass, plant growth rates, biomass yields, plant metal concentrations, and mine waste metal concentrations at the end of the growth experiment. These data are included within this dataset.
