Why Should You Use a pH Tester Kit

The best reason to use a pH tester is to make sure that the soil is right for your plants. Keep in mind that not all types of plants will require the same kinds of soil. They may have varying requirements, especially in terms of the pH level. If the pH level is too little or too much, the health and growth of the plant will most likely suffer.
If the soil has too much calcium, the pH meter will show that there is a high level of alkaline. On the other hand, if there is a high concentration of phosphorus, the readings will show that it is acidic. When the level of acid or alkaline is too high, the plants will not thrive. Therefore, by having the soil tested, gardening frustrations can be minimized.

What are the Different Types of pH Testers?

Best pH Tester KitDifferent types will have different levels of effectiveness. The most affordable comes in the form of strips or paper. In this case, the color of the paper will change depending on the pH level of the soil or the water that is being tested. More often than not, it comes with a reference to easily determine the corresponding pH level depending on the resulting color.
The next type is the one with probes or sticks. Most of the options that are mentioned in this guide belong to this category. You need to stick the probe on the soil and on the top part, the readings will be shown.
You can also opt for electronic or digital soil testers. They are the most advanced from the three and usually expensive. The results are quite accurate and preferred by many people because of the convenience that it offers.

How to Choose the Best pH Tester Kit

Similar to shopping for other gardening tools, the options can be overwhelming. Nonetheless, you should still take the time to evaluate the possibilities, which will be easier if you consider the factors briefly mentioned below:

  • Ease of Use: For sure, you hate complications! Therefore, you have to choose a pH tester that is as effortless to use as possible. It should have a simple design and the manufacturer should provide comprehensive instructions on how to use the product.
  • Accuracy: Your pH tester will be useless if it is unable to show the accurate results. One of the best ways to determine its accuracy is to read reviews from its past users. Through the experiences that they are sharing, it will be easier for you to determine how one product is better than all others.
  • Versatility: A good option is one that can deliver multiple functions. More than being able to measure the pH level, it must also measure other things, such as sunlight and moisture, making it a multifunctional gardening tool.

How to Take Care of your pH Tester

To make the most out of your home soil test kit and to make sure that it can deliver accurate results even after a long time, care and maintenance should be prioritized. That being said, here are some of the most important things that you need to do:

  • When you are not using the tester, keep it in a safe place, away from direct heat and moisture. It is a good thing that some options are already inclusive of a case.
  • The use of the right solution for calibration is also important, making sure that the readings remain accurate. See to it as well that the meter will be calibrated based on the schedule that has been specified by the manufacturer.
  • Before storing the tester, clean it thoroughly. If there are traces of soil on the end of the probe, it could harden over time and can be more difficult to remove.

How to Use a pH Tester

This is actually going to vary depending on the pH tester that you are using. If in case you are using a probe, which is the most common, here are the simple steps that you have to follow in its use:

  1. Dig a small hole on the part of the garden with the soil that you want to test.
  2. Once the hole has the right depth (depending on what the manufacturer recommends), fill it with water. It is best to use filtered water.
  3. Once the soil turns muddy and once the liquid has been drained, it is now time to start with the test. Stick the probe or the end of the meter on the wet soil. Hold it for about a minute or depending on what the manufacturer specifies.
  4. Read the results. When the display shows 7, the soil is neutral. When it is less than 7, it is acidic. On the other hand, when it is more than 7, this goes to show that the soil is alkaline.

At the end of the day, the most important is to religiously follow the instructions from the manufacturer to be confident that the readings will be right.

What are the 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:

  1. Dig about six inches deep and take a soil sample.
  2. 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.
  3. Place one cup of the soil in a glass container.
  4. Add water and mix the soil until it becomes muddy.
  5. Add a half cup of vinegar and mix.
  6. 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.

  1. 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.
  2. Add water and mix until it becomes muddy.
  3. This time, instead of using vinegar, you have to put baking soda. Stir.
  4. 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.
