Yes ag lime is just crushed limestone rock.

If you have acidic soils I really like the limestone rock to use in and around the pond.

One negative thing it will do though is grow algae and especially filamentous algae really well. Dump some limestone rock in a pond and in short order it will be covered with algae.

But otherwise I think it is very good for the chemistry of the pond water.
