A use for pulverised egg shells

[lottie dolly]

On reading about the uses of the above,i like the idea of putting a little in the bottom of planting holes,to give a calcium boost to tomatoes,has anyone tried it,if so was it any good,i put a few in the blender and got dust,so was just thinking aloud,by reducing it to dust,should incorparate into the soil,where as crushed shell is like sharp stones,what do you think,and what else would benefit look forwards to answers.

I "roast" the shells in the bottom of the oven, crush them roughly and feed them back to the chooks for their calcium boost.

thats what i have been doing,they do not want to eat it all,hence my post,i also roast em first,got quite a bit all crushed in a airtight container,

Sounds like a good idea, LD. Anything prone to blossom end rot would probably benefit - peppers and aubergines, as well as tomatoes. I use our hardwood ash for the allium family and also for squash and courgettes. There's some calcium in the ash, and I have to say, the plants seem to benefit from the extra.

I roast mine same as VC does then add then in planting holes for toms, courgettes and brassicas.

I don't bother roasting them. I just crush them in a pestle and mortar. I don't have chooks but I do have wormeries so the egg shells go in there.

They are also brilliant at putting around the base of "Hosta's! to ward the slugs off!

Might this be of interest?
Eggshells - Do They Decompose In The Garden?

Some of it not terribly scientific, but I found the early part and some of the comments useful. The upshot is (if you don't want to read it) that for eggshells to be of any benefit to the soil, they need to be ground extremely finely. Plus, they won't have much effect if the soil is not acidic. That's not to say that roughly crushed shells might not prove a useful slug or snail deterrent.

I've read that egg shells in wormeries are good as long as they are crushed because worms have a form of gizzard that uses the hard shells to help chew up their food.

Light weight liming... if you crushem up good

apparently... - i just chuck em in the compost and hope for the best

Thanks for the repies,thanks Bren for clarifying things for me,
As well as planting holes,another thought was making our own potting on compost,and the relevence of egg shell powder,coffee grounds and who knows what in the process,my mind is working overtime on everything lately and not just gardening
