Other claims from this paper (11)
- Intervention effect Newberry sludge supported growth comparable to fertilizer.
- Intervention effect Fresh Athens sludge supported growth comparable to fertilizer.
- Intervention effect Chicago sludge at 68 Mg ha −1 produced smaller seedlings than fertilizer.
- Intervention effect Aiken sludge yielded poor growth and mostly nonplantable seedlings.
- Intervention effect Pisolithus ectomycorrhizae formed less readily under sludges than fertilizer.
- Intervention effect Artificially inoculated Thelephora formed ectomycorrhizae equally readily on sludge and fertilizer seedlings.
- Intervention effect Natural ectomycorrhizae formed less readily under some sludges than fertilizer.
- Intervention effect Chicago sludge increased cadmium in seedling roots, stems and needles two to fourfold versus other sludges.
- Mechanism The authors attributed poor growth under old Athens sludge to macronutrient deficiency.
- Mechanism The authors considered heavy metal toxicity a possible cause of poor growth with Aiken sludge.
- Mechanism The authors considered heavy metal toxicity a lesser possible cause of poor growth with Chicago sludge.
