Ground Eggshells as an Effective Liming agent. FIELD STUDY.

Came across this article during my organic venture. Supports the use of ground eggshell as liming agent. Since there are not many articles on here about eggshells I'd though I'd post this for a reference. Enjoy!

I actually cracked some eggs yesterday for breakfast and wondered if and how they would be useful. I'm trying to be as organic as possible with my grow. Thanks for the info!

I love the idea of using common household items to achieve a proper growing environment. Not to mention on a low budget!
