Other Ways to Test Soil
While a pH tester can come handy, gardening experts also recommend other unique ways to evaluate the quality of the soil. For instance, if you would like to test for alkaline, here is what you need to do:
Dig about six inches deep and take a soil sample.
Remove any debris from the soil and make sure that only soil remains. If there are clumps, break them before you proceed with the test.
Place one cup of the soil in a glass container.
Add water and mix the soil until it becomes muddy.
Add a half cup of vinegar and mix.
At this point, if there are bubbles, this is an indication of alkaline in the soil.
From the steps that have been mentioned above, if the bubbles did not form, proceed to another test, which will help you to determine if the soil is acidic.
From the portion of the garden where you retrieved the soil that has been initially tested, get another one cup and place in a glass container.
Add water and mix until it becomes muddy.
This time, instead of using vinegar, you have to put baking soda. Stir.
If there are bubbles, this shows that the soil is acidic. If nothing happens after testing for both alkaline and acid, this means that you have a neutral soil.
However, while these are great alternatives, I suggest that you still use a pH tester kit. After all, there is no substitute for the real thing if you want the results to be more accurate.
