Tom Jaszewski expounded:

pH is a figment of inorganic gardeners
imagination....

Tom, that's not true. You need to put in a disclaimer that it depends
on where you live. Without limestone, my soil is naturally 4.5 to
5....way to acid to grow grass. And I do grow a nice lawn,
organically, using regular old fashioned limestone applications twice
a year.
