Solid calcium organique Growing additif

Hello,

I’m looking for an organic solid calcium additif to ad in the soil.

I seen oysters shell or dolomites lime but i don’t find one 100% organic that can be ship to Europe.

Egg shells work

Gypsum.

I can't find any of the 2 available in contry

do you things that can’t use that in my soil ?

They don't have chickens or chicken eggs in your country? Seems weird....

You can’t find egg shells in your country, don’t you eat eggs?

How many grams of shells eggs per liter of soil ?

Gypsum should be available everywhere globally. It's used in concrete for god sake!

gypsum is fast acting. egg shells, washed, oven dried and ground up into a powder work too.
the gypsum or calcium sulphate, is finer and therefore more redaly absorbed into liquid and therefore , quick to be absorbed into your plants
use 2 1/2 oz per usa gallon of water, and give each plant one or two capfulls
