I spent seven years working as a coal fired boiler operator and dealt with fly ash on a daily basis. While it would be presumptuous of me to contradict the learned articles, I personally would not apply fly ash to my soil as an amendment.

We burned Wyoming coal and the resulting flyash was sampled and tested on a regular basis and the levels of heavy metals was scary to say the least. We were warned constantly to shower immediately after being exposed to flyash for a length of time. There were also warning labels that our flyash was possibly radioactive. Ours was landfilled and buried.
