eggshells and nutrients

[Rwise]

Soil has sulfur in it, sulfur + water + time make sulfuric acid, this will dissolve the egg shells, slowly depending on the PH. Higher PH is slower, lower PH is faster. They will also buffer the soil a bit

Egg shells in soil are good for stopping slugs or worms attacking plants its like glass to them only way to get plant to absorb it is by baking them and mixing it with distilled vinegar mate

This is another myth growell. Egg shells are not sharp at all and will not negatively affect slugs or worms what so ever.
You're just being silly. Place a saucer of beer nearby or use a product called Sluggo.
