Elaine has spread controversy her entire career, starting when she called out Monsanto on not disclosing some studies on a GMO product. That being said, she has a lot to offer from her extensive work on soil microbiology. I'm neither condoning or condemning her practices, I don't know enough to judge. She is worth hearing. As far as speaker fees, we have paid several speakers to talk at our seminars. How we do so is confidential. Her knee is bad enough that she is unable to drive and has a crutch. She limped around the room without the crutch, but I'll bet she was hurting the next day.
