comment Does oxygenated watering benefit deep clay?
i've since done a little test with a nugget of deep sticky clay. it doesn't disperse at all in plain tap water. this by the way is an indicator that gypsum won't help. Anyway, I've added a good dash of h2o2 to some water in a glass with the dense nugget of said clay. amazingly it started dispersing, with tiny bits of clay coming off in every direction. I know this is not a proper scientific experiment but at least an initial proof of concept or so. I eneded up with half the clay turning into a chocolate color solution and sediment. pretty impressive and quick dispersal of clay I must say.

Thanks for the response. As has been reported by many in-situ studies, gypsum only works on specific clays and the amounts required are impractical for deep clay. The "miracle gypsum" type writeups are another brand of snake oil. I have been adding gypsum, dolomite and lime over the years. It's done nothing for deep clay.

thanks. i've read this before my initial posting. These are the things i'm referring to. I was hoping someone had done some of these things in a home garden setting. Since i've dug up some deep clay, I might add h2o2 a few times to see what happens to the clay.

Having finally improved my vegie beds with sharp sand and crusher dust after years of adding loads of composts and manures, I'm afraid adding humus and other organic matter to heavy clay does not improve it to any degree. It still remains wet in winter and dries out quickly in summer. The organic matter "burns" up quickly and back to structureless soil by mid-summer. Organic matter is good for soil that already has some structure. Water authorities use ozone to sterilize drinking water supply. Aerating aquariums must be junk science also? There are snake-oil salesmen in every industry.

I guess I'll have to get a oxygen test kit to see what the oxygen saturation of tapwater is. Supposedly the oxygen saturation isn't that great in tapwater, so that iron and manganese (in particular) don't fall out of solution and foul pipes and devices. Pool or pond water that isn't constantly agitated tends towards anoxia, so it's probably not as simple or quick for oxygen to saturate water at nominal pressure. There have been promising agricultural studies adding h2o2 or just o2 into soil..but not the kind of convincing results i'd like.

New Scientist is not peer reviewed, so nothing to brag about there. As I said I have deep clay soil with a bit of topsoil. I'm trying to figure out a way to improve the deep clay so that my fruit trees and even vegies grow better, without adding another metre of topsoil on top. Since the subsoil doesn't drain well, neither does the topsoil. Increasing oxygen in the deep clay would not only help the plants but also the land itself, upon which our house rests.
