FAQs
Add baking soda to one jar and mix. Then add vinegar to the other and mix. If the baking soda mixture bubbles, you likely have acidic soil; if the vinegar mixture bubbles, you likely have alkaline soil. This method is best used as an initial assessment of your soil pH or as an educational activity.

How do you test pH without a kit? ›
Red Cabbage Test
First, cut red cabbage into small pieces, boil it in water, then strain the liquid. Add a small amount of the boiled cabbage liquid to a glass of water, and observe the color change to determine the pH level. The pigment in the glass should turn red in acidic environments with a pH less than 7.
What is the most accurate way to test soil pH? ›
Testing with vinegar and baking soda can indicate which end of the pH scale your soil is leaning. But a soil pH testing kit provides more definitive results for an exact measurement. You can purchase testing kits at most garden centers and through local cooperative extension offices.
How do you make a homemade pH test? ›
Use the litmus paper to test for acidity.
No change means that the solution is either basic or neutral, but not acidic. You can make red litmus paper (that turns blue when exposed to a base) by adding acid to the indicator solution before soaking your paper.
Can you test soil pH with vinegar? ›
Place a handful of soil into a clean container. Add ½ cup of white vinegar. If the soil starts to fizz, it's likely high in alkaline. If the test proves the soil's alkalinity, amend the soil with sulfur or pine needles.
How do you test soil pH with paper? ›
Measure pH
Insert a small portion of the pH paper in the liquid above the soil and allow the liquid to move up into the paper. Remove and let the color develop for 60 seconds. Read the paper color using the pH color chart.
How to check soil pH with baking soda? ›
Put a soil sample in two small containers. Mix a little water to the soil in each container to dampen the soil. Add baking soda to one of the containers. If the baking soda causes the soil to bubble, it indicates that the soil is acidic with a pH below 7.
Can you test soil with pH strips? ›
Soil acidity can be determined from pH testing strips, but the measurements may not be as accurate as using a meter or bringing a soil sample to a testing site.
What is the best way to test pH? ›
pH Meters. The most precise of the 3 test options, pH meters measure a solution's pH by measuring the electrical potential difference between the pH electrode and a reference electrode. The meter then coverts this potential to a pH reading.
You will Need:
- pH paper, which gives a number that shows how acidic a chemical is by changing colour. You can buy this cheaply or make your own!
- Straws.
- Coca-Cola, or fizzy drink of your choice.
- Milk.
- Tap water.
- Vinegar (cider and malt)
- Laundry detergent.
- Table (make your own to record your results)
Red cabbage juices is the best known edible pH indicator in your kitchen but there are many safe fruits, vegetables and flowers that change color in response to acids and bases such as eggplant, beets, blueberries, cherries, onion, raspberry, grape juice, turmeric, and even tomatoes!
How to test soil pH with baking soda? ›
Put a soil sample in two small containers. Mix a little water to the soil in each container to dampen the soil. Add baking soda to one of the containers. If the baking soda causes the soil to bubble, it indicates that the soil is acidic with a pH below 7.
How much baking soda to raise pH in soil? ›
Mix a tablespoon of baking soda into a gallon of water. (You can use this ratio to increase or decrease the amount you need, based on the size of your garden.) Be careful not to add too much baking soda or use too much of this mixture in your garden, as it could create an imbalance.
