Biosolids application
nounPronunciation: /baɪoʊˈsoʊlɪdz ˌæplɪˈkeɪʃən/
The process of applying treated organic residues (sewage sludge) to abandoned mine land to improve soil structure, add nutrients, and facilitate vegetation establishment. Biosolids must meet regulatory quality standards to prevent contaminant transfer to reclaimed ecosystems.
Plain English
Using treated sewage sludge on abandoned mines to improve soil and help plants grow while meeting safety standards.
Etymology & History
Usage
"Biosolids application enhanced soil conditions at the copper mine site, allowing native grasses to establish successfully."
