Eggshells for soil
Are broken up egg shells good for gardening? How do they affect the soil?
Submitted by BHGPhotoContest

Eggshells are basically calcium carbonate. As they break down, plants can use the calcium in them. However, it takes a long time for them to break down, so the benefit will be minimal at first. Calcium also has the effect of raising soil pH, but it would take many pounds of eggshells to make a difference in the soil pH, so, again, their effect will be minimal.
