Add pulverized egg shells (put in blender with some water) to your

Get serious. Ted already has enough goofy advice. If the lawn is
no bigger than 3m square and he has 5 years to wait this is a good
idea.

Explain your goofy response.

I appreciate your aim of re-use and recycle but in this case it isn't
practical.

How many eggs do you have to eat to get enough shell to spread on a
yard? Sure it depends on the size of the yard but we are talking
about some kilos of egg shell.

How fine can you grind it? Not very fine without a mill. Fine
garden lime or gypsum will take months to work, ground shell will be
much coarser and take years.

IMO, if the OP wants to add calcium, all he/she needs to do is to
just find someone who still has a wood burning fireplace/heater, then
s/he could just spread the seived ash which contains calcium. It
should be spread thinly like icing sugar (confectioner's sugar in
USian) on the top of a Victoria Sponge cake.

OK if the pH needs to be raised. As you say use it sparingly as it is quite
alkaline and some of the alkaliine stuff (the potassium salts) are soluble
and so fast acting. For a novice there are safer alternatives.

For nitrogen I'd spread 'your friend and mine' - good old blood and
bone.

Blood and bone would be fine.
