I'm trying to find studies done on pond gleying. All the resources I found on it are from permaculture forums, but that isn't good enough to convince me (no offense everyone)...anyone know of any studies?
But those links just talk about the process of gleying as I had learned about it in school- the process of water-logged soils becoming oxygen depleted and thereby turning grey from the iron and such. The only way I can see this possibly helping seal a pond is that clay particulate settle to a particular horizon in the soil profile. However, this clay is not compacted or anything - it's just there in larger quantities than when it's spread over the entire soil. I guess that's better than nothing, but you still get leakage and what gleying is supposed to do is prevent that.
So far I am becoming less convinced that gleying really has the affect of sealing the pond from water loss. I think if I have to seal a pond, I'll go for compacted clay.
I appreciate your help.
