Commercial soil test kits are widely available and very accurate. But if you want to know right now whether your soil is acid or alkaline, try these tests recommended by Almanac.com:
1 Place 2 tablespoons of soil in a bowl and add a half cup vinegar. If the mixture fizzes, you have alkaline soil.
2 Place 2 tablespoons of soil in a bowl and moisten it with distilled water. Add a half cup baking soda. If the mixture fizzes, you have acidic soil.
If you get no soil reaction to either test, your soil has a neutral pH.
Counter acidic soil with ground limestone. Treat alkaline soil with ground sulfur.
