Hello,

I just heard an ad for crushed basalt on the radio but forgot the
product's name before I could write it down. The name is something
similar to "Nature's Own fertilizer" or something like that. It is
supposed to be better as well as less expensive as "other" products,

it's available locally.

Thanks,
