I'm starting to brain storm some ideas for next year's spring garden projects early and have soil amendments on my brain. Been fighting heavy clay soil in Alberta for years and am gonna stop amending it and just pull it all out and start from scratch.
There are things like bulk garden mix, which I might just use as a control in one bed, but want take a shot at building my own soil recipe. An ingredient that's come up sporadically, but doesn't seem to be widely used is crushed ceramic. A very porous material I'd think it's have great micro pore potential for water retention and mineral ions. My guess is that it's not used very widely because in large quantities it may be hard to find not contaminated with other construction materials.
I've found several people on classified advertisement websites in my area with PALETTES of un used roof tiles that I'm thinking of picking up and giving a go. Would have to crush them myself and will do some other research into the manufacturing process if there's some chemicals present in the ceramic I'm not aware of.
Has anyone here some thoughts on this idea?
I'd be using it in combination with bio-char, peat moss, crushed sea-shells, normal compost, and then the rest some regular "garden mix" from a bulk store locally.
