Soda water does not contain any carbonic acid. Instead, you are looking for a liquid or granular soil conditioner (sometimes labeled fertilizer with soil conditioner)
that contains humus or humic acid. If your local agricultural supplier carries Kellogg's Nitrohumus -- then you can mix this in either: with the clay, sand, pea gravel, gypsum, and ground coir as you amend the soil, or mix it in with your mulch after the fact.
