How to determine the acidity and alkalinity of soil?

Method 1: Test with vinegar and baking soda

Pour baking soda and vinegar into the soil and observe if there are bubbles with a hissing sound. If bubbles form with vinegar, then the soil is alkaline; if bubbles form with baking soda, then the soil is acidic.

Method 2: Visual inspection

You can observe the soil in the flower pots you use. After watering, if the soil dries up quickly and becomes severely compacted, it is mostly alkaline soil. If the soil is loose, it is mostly acidic soil.
