An interesting note about eggshells

Eggshells are a good source of calcium for plants. Commonly people recommend things like “12 crushed eggshells for a tomato plant”. Problem is, storing eggshells in their original shape takes quite a bit of space. On the other hand, they are kinda hard to count once they have been crushed… Enter the realisation of a long held dream:

My shiny new kitchen scale

Yes, that is a kitchen scale. Not the pretiest, but by a long shot not the ugliest scale I saw on the day, it weighed in at a fairly affordable R 130 from Game. The only question is why it took me so long to buy one. I guess after hinting that I want a kitchen scale before several successive birthdays and christmasses I should have gotten the message.

But more importantly, said scale loaded with 4 large eggshells (yes I did remember to zero with the bowl on) indicates that each shell weighs about 5.5g. So there you have it, if ever you need to add 12 eggshells to your tomato plant, you can just weigh out 66g of crushed eggshell.

    How big were the eggs you used to get to 66g? Medium/Large or X-large?

    I've been hinting at an electronic scale for years, and I am still waiting. Maybe i should just go out and buy one myself!
