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.


Compost is good for depleted soil for many reasons but it will not increase
calcium very much if at all.

if you add enough to improve the habitat for
worms they will increase calcium levels. worms
do secrete calcium.

also many plants do have calcium, that doesn't
disappear when compost is made (or if it does
where does it go?).

just be careful as adding too much compost all
at once will likely encourage fungal diseases (
if you smother the grass).


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

What do you suggest?

Thank you.


Ted where did you get this information? Have you tested the pH? If not do
so before you act.

agreed.

but really, it makes more sense to plant grasses
or add other plants to the mix that will tolerate
existing conditions. leave the amendments and
compost for the garden beds that you want to alter
to fit specific crops (much smaller areas, less
expensive, etc.).
