Best Soil pH Testers for Your Garden and Backyard

Gardening is a science, luckily, it is nothing complicated, and information is abundant. You may not always be successful in growing some plants due to the soil pH, which is why you need the best soil pH testers.

pH in full is ‘potential of hydrogen’ and it is a measure that is used to test how many hydrogen ions are in the soil against hydroxyl ions. Many plants require land that is a bit acidic, so in many cases, you want a pH of less than seven. This allows the plants to have access to the nutrients in the soil, which are usually in the form of ions. The wrong soil pH means that your plants can’t access nutrients so they will die. 

There are various ways to test the pH but using an electronic soil tester is what I have found most accurate for home use. We will have a look at everything you need to know here with the best-rated pH soil tester review.

My top pick:

Professional pH Soil Tester – Sonkir Soil pH Meter, MS02 3-in-1 Soil Moisture pH Tester

Sonkir Soil pH Meter, MS02 3-in-1 Soil Moisture pH Tester
ADVANTAGES:
  • Detects pH, moisture, and sunlight.
  • It gives results faster.
  • Double-needle assures accuracy.

The Sonkir tester uses some of the best pH detection technology to give you results almost as good as lab tests. It is excellent for use anywhere both indoors and outdoors so long as you use it on fine soil. This pH tester is durable, and it is a 3-in-1 tester, so you get value for your money.

While it is not a unique looking tester, I love just how accurate it is and that it has extra-long probes so if you need to reach deeper roots, then this works perfectly. The double-needle detection helps in faster finding since each of the probes measure something different. Switching between the different modes is easy and convenient since the different settings are marked.

You can use this cheap soil pH tester both directly on the soil, and by making the soil and water mixture, so you can do both and get the average, but I can assure you the difference shouldn’t be huge. The pH meter has a basic range between 3.5 and 8, and it comes with a chart to help you. It also has scientific data monitoring that allows you to check on the progress of your plants carefully.

Why Do You Need a Soil pH Tester?

A soil pH tester tells you just how acidic or alkaline your soil is so you know what plants you can grow. There are three types of soil pH testers, namely electronic, paper strips, and chemical color dyes. Among these, I have known the automated tests to yield more accurate results, although the other options are high and can give you an idea of what you’re working with.

The best pH tester for soil will tell you the current state of your land so that if it is wrong, you can work on improving it using fertilizers and pH adjusters if needed. This ensures that the earth has the correct pH for your choice of crop. Knowing the pH allows you to have a better chance that your plants will thrive and that you will get a good yield.

Are pH Testers Accurate?

Are you wondering how accurate are soil pH testers? Well, accuracy depends on the type and quality of tester you buy. I prefer electronic testers since they give the most accurate results compared to all the other options. Chemical colored dyes will have to be number two on accuracy. They’re also easy to use since you only need to compare the results from mixing the stain and soil to the chart provided.

The paper strip testers are a bit tricky to use, and you may have to test again using a different method for more accurate results. Please note that these are not litmus papers. You can get regular paper strips from your local gardening store, and they should give you a good idea of the acidity of the earth. However, I suggest getting lab-grade pH testers since they are more accurate.

How Do You Read a Soil pH Tester Result?

First, you need to understand the basics of acidity and alkalinity, which runs from zero to fourteen. Seven is the neutral number, and anything above it is alkaline, while below seven is acidic. Many of the testers usually come with a chart to help you in accurately reading the results depending on the examiner that you use. 

Many of the electronic testers have a probe that allows you to insert it directly into the soil to get a reading. There are cases when it may not work well, and you end up with inaccurate results. The best way that I use for correct results is by making soil and distilled water mixture. Put some soil into a container and add water then stir so that it incorporates well. With this, you can use the electronic or strips to test, and your results should be as accurate as possible. You can do it a few times if you’re not sure as suggested in soil pH testers reviews.

It is usually advisable to use the chart that the tester comes with since some devices have a different reading from the basic one. This ensures that you have a correct read and that you decode it correctly for a good idea of the state of the soil.

As you will see in the reviews below, many are electronic although they all offer different benefits over others that I will discuss.

ADVANTAGES:
  • Scientifically accurate.
  • Affordable for 3-in-1.
  • Great for both outdoor and indoor.

DRAWBACKS:
  • The probes are not sturdy.

The iKKEGOL is another favorite if you are on a budget. It offers three different tests, which it does with great accuracy. It measures soil moisture, pH, and solar intensity. 

The probes on this pH soil tester are made of bronze and silver that measure moisture and pH, respectively. They are, however, not the strongest, so be careful when inserting it into the soil. For this reason, don’t use this in rocky earth as you risk damaging it and getting inaccurate readings. It has an easy to use switch that allows you to toggle between the different settings.

I do not like that the screen is so tiny, so if your eyesight isn’t excellent, you may struggle reading it. However, it gives steady readings with little differences, no matter how many times you take it. It doesn’t use batteries so you can use it as long as you can with no issues.

How Do You Find The Best Soil PH Tester?

Your choice of the best pH tester depends on what is most important to you. For example, if you only need to know the pH and not the soil mineral composition, then an electronic device is perfect. However, if you want to know the nutrients in the soil, a chemical test would give you the desired results. You also need to check on:

  • The number of tests that you can perform, for example, pH, moisture, and light.
  • The design of the tester and the way it can be used and read.
  • pH scale range depending on the type of soil.
  • Type of soil, for example, waterlogged, dry, or rocky.
  • Accuracy of the device. Ensure that you check pH testers for soil reviews.

Remember to fully follow the instructions given on every test for the best results. With chemical tests, just like in a chemistry experiment, everything needs to be measured. Without this, you won’t achieve the correct outcome.

Frequently Asked Questions about pH Soil Testers

If you are new to testing the pH of the soil in your garden, then you must have some questions. Here are a few common ones about the best pH soil tester.

How Do Soil PH Testers Work?
The pH test measures the number of hydrogen ions in the soil, so the testers use electrodes that attract the ions to it. The concept is the same for both chemical and electronic test kits. So the hydrogen ions get attracted to the electrodes on the tester, which then sends a reading to the pointer that shows the level of ions.
Will Soil PH Testers Work Water?
No, soil pH tester won’t work water since the sensors are specially made to test the hydrogen ions in the soil and not water. However, some soil pH testing strips may work on the water. The biggest problem is that you won't get an accurate reading. Many soil sensors have a limited pH range, so if the acidity of your water is beyond that, you won’t know.
How to Test Soil pH with Liquid Tester?
If you’re using a liquid tester then you only need to put some soil into a container, add the chemical liquid, shake and wait for the color change. Remember to use the chart provided for an accurate reading based on manufacturing.
How to Use a Digital Soil pH Tester?
With a digital tester, it is easy to dig it directly into the soil and wait for the reading. Alternatively, make a mixture using distilled water and soil then leave the probe in it until you get a reading.
How to Use Rapitest pH Soil Tester?
Put soil into the test tube up to the level indicated, add the chemical in the capsule and water up to the required standard. Shake properly then leave to rest for a couple of minutes. Put in the tube in the detector and compare the results to the chart.
Do Cheap Soil pH Testers Work?
Yes, they do. The important thing is to check the accuracy level and some of the reviews from buyers. Not all cheap testers may work, but many of them do.
Can You Test pH in Soil with a Pool Tester?
No, a pool testing kit will likely give you a wrong reading since it is designed for a different task. Hence, the pH range will also be varied. You may get a result, but the accuracy is not one you should rely on.
