How To Test Soil Acidity/Alkalinity without a Test KitFind out if your soil is acidic or alkaline without a pricey test kit.
- Scoop some soil into a container. Then, add a half-cup of vinegar. If the soil bubbles or fizzes, it's alkaline.
- If there's no reaction, scoop a fresh soil sample into a second container. Add a half-cup of water and mix. Then, add a half-cup of baking soda. If the soil bubbles or fizzes the soil is highly acidic.
- Amend your soil with wood ash or lime, if it's acidic. Amend your soil with sulfur or pine needles, if it's alkaline.
