So I was simply looking up how eggshells can help with gardening and I also stumbled upon something interesting – eggshells are good sources of calcium for humans.
One thing I’d like to point out when researching this subject if the article you are reading about eggshells doesn’t tell you to grind the eggshells into a powder, immediately stop reading. Chances are the person who wrote the article doesn’t know much about what they are talking about and/or are just regurgitating information that they heard or read from another misinformed or unreliable source.
Why do I say this? Well, for instance, putting cracked eggshells in your garden to use to fertilize the soil simply is not going to work as intended. The larger the pieces of eggshell, the longer it takes to decompose. So the nutrients you think you’re adding to the soil aren’t going to have any effect on whatever you are growing because the shell isn’t going to breakdown in time to even release those nutrients into the soil.
Think about this – what will melt faster an ice cube or an iceberg?
