Would crushed eggshells be useful as a soil improver for clay in a similar way to grit? I realise they would break down eventually but they seem to take years. I don't want to put them in the compost bin for that reason.

What's the soil pH?

So sorry to take so long to answer. I've been having prpblems with my computer.
I don't know my soil pH -- only that it's heavy clay.

Here in the desert, the soil is alkaline, with a pH as high as 9. We only use eggshells in the compost, since they tend to raise the pH. If your soil is derived from chalk or some other kind of limestone, it may be neutral to slightly alkaline, which will allow the eggshells to stick around long enough to help improve drainage. Otherwise, in the Devon climate, the soil is likely to be quite acid, which will dissolve the eggshells faster than you might believe, making them no more effective than any other form of lime. At least they are "free"!

Thankyou Tb. I know virtually nothing about soil, which is daft when I've been gardening for 20 years. So no benefit to Devon clay then, but as you say, free and some people do find them useful in the slug war. How different things must be in Arizona.
