Egg shells placed under the surface of the soil around your tomatoes, and
other plants bothered by nematodes, will draw an insect (I don't know which
one) to eat the membrane in the egg shells. Once they get there they find
that they like nematode eggs better and will clean them out. I read that in
one of my tomato books, but don't remember which one.

What is your source for this statement?

The best way to provide calcium to plants via eggshells is to let them
dry completely in the sun and if you have a morar and pestal grind
them into powder. You can also put them in a plastic bag and roll
them with a rolling pin till they are powder.

A much more effective way to provide Ca to soil is in the form of
powderd milk. It's very fast.
