I’ve recently tried mixing the used coffee grounds in baking soda, and I’m seeing a very visible chemical reaction. I haven’t tried putting it in the ground yet though.

    Just compost them. No need to add baking soda unless you want your soil to be light and fluffy like pancakes.

    They’re high in nitrogen and when mixed with carbon based materials will make excellent compost/soil amendment in 6-12 months. Shorter if you hot compost or bokashi.
