I've just read the following gardening tip. Add baking soda to a cup

it bubbles, the soil is alkaline.
Looks like it was written originally by someone with a smattering of
chemistry and no practical gardening experience. I fully agree with
what the others have said. The amount of CO2 liberated in such tests
wouldn't be nearly enough to form decent bubbles unless it's a chalky
soil with lumps of free chalk, when it's pretty obvious what sort of
soil you've got.
I'm sure you're all correct but - Has anyone tried this at home?! I'm
almost tempted! ;-)
