Hello,

The soil in our yard appears to need nitrogen and calcium. The stuff
I've read, and the advice I've been told, says to add soil amendments.

How?

Okay. I'm far from an expert. Let's start at the beginning.

If I add something like dolomite (for calcium), I'm told that will
kill microinvertebrates and make the lawn dependent on chemical
fertilizers indefinitely. I don't want that!

So let's add compost. But, in order to add enough calcium in compost
form, I'd have to add several inches (in vertical depth) of of
compost. That would smother the lawn. Nope. Not gonna do it. I
don't want to re-plant the lawn.

Obviously I can't believe everything I hear or read.

What do you suggest?

Thank you.

Add pulverized egg shells (put in blender with some water) to your lawn.
Egg shells breakdown slowly, so you won't get a quick response, but they
will break down eventually.
