Question for Elaine

[Lmvine1]

In an interview with an Aussie here
http://www.nutri-tech.com.au/Interviews/Interviews10.htm
Elaine is quoted below.  I would like for her to elaborate from her experience and maybe provide more reference that could be researched.  Dan

Elaine:  "The reason the pan is formed is because the soil got compacted, then went anaerobic. It always is the micro-organisms getting the life back into that
hardpan that opens it up and prevents it from reforming as a compacted hardpan zone. Soil-life is the key. It needn’t take very long with biology. Work at Ohio State University shows that you can break up a hardpan at four inches in six weeks by just getting the right kinds of fungi into that soil. You can break up a hardpan at four feet in six months."
