Egg shells instead of lime /dolomite

[Luigi69]

Hello all, could I use the eggshell in the potting mix?
I do put the farm grade oyster shell and dolomite what about eggs? I do put eggshell in the vegetables bed as it is a bit acidic,
Everyday for breakfast we consume about 8-12 eggs, I lightly toasted in the toaster and throw in the garden,
Could I save them reducing in powder and mix with the potting soil?
Thanks in advance

Eggshell is perfectly viable as a source of calcium and some trace elements. Baking them is a good step to maintain mix sterility. Be sure to grind well to encourage nutrient absorption.

Eggshells/calcium are basic, not acidic.

Yea they are great to use, though they take some time to break down for the plant to be able to uptake.
I wouldn't count on them to help your plants in the short term.

and yes its for a long term not right away, i want to use as we use limestone, its a long term thing

I’ve tried half bucket of crushed/grinded egg shells and crushed calcium/magnesium tablets, in my personal experience, i couldn’t see any effectiveness to the plant. When i applied calcitic lime, fig roots were all over the surface in as litte as one week.

As mentioned they do take a long time to break down. I sprinkle coarsely crushed eggshells around cuttings to discourage slugs and snails from snacking on the tender new growth.

I saw a video advocating putting them in a blender with water to create a slurry of fine particles.

All our egg shells are fed back to the chickens.
They love it. 🐔
