What is Soil pH Meter?

A soil pH meter is a gardening tool that helps determine the acidity or alkalinity of the soil. It enables you to know what to do to make your plants grow better. Soil pH meters don’t just measure the soil pH; however, they can also measure moisture and light intensity.

Types of Soil pH Meters

There are several types of soil pH meters. Some only test the soil pH while others test a few other parameters.

For instance, the Allotpower soil pH meter, apart from measuring soil pH, can also be used to measure soil moisture and light.

Other devices, such as the Bluelab Metcom Combo pH Meter, can also test soil temperature or conductivity.

There are pH meters that work with the help of batteries, such as the Pensoil pH meter. However, most are usually self-powered and don’t need batteries.

Which Soil pH Meter is suitable for you? 

There is a variety of soil pH meters available in the market. We understand it might be problematic knowing which one is best for you.

A simple design and an easy-to-use soil pH meter should feature high in your list of suitable soil pH meters. You shouldn’t have to struggle to use a soil pH meter.

A good soil pH meter should also have extra functions. Most of the soil pH meters we have discussed here have at least two features to go with testing soil pH.

A suitable soil pH meter should also be durable and of high-quality design. You don’t want to be continually looking for replacements.

A good soil pH meter should also be quite affordable. It is not always a higher price means a better product.

Finally, an excellent soil pH meter should give accurate and reliable results. You don’t want a device that gives you results you can’t trust.

How to Test the pH Level in Your Soil:

Since some of the pH meters on our list were strips, we will show you how to use strips and the other more conventional soil pH meters.

How to test for Soil PH with a Soil Strip

Step 1

Get the needed soil sample by digging in the required area.

Step 2

Using a teaspoon, measure one to three teaspoonfuls and place them in a clean container preferably glass

Step 3

Add a little amount of distilled water then vigorously stir to mix the soil with the water.

Step 4

Filter the resulting mixture with a coffee filter into another clean container.

Step 5

Gently dip the strip in the solution for some time. Note the color change then compare it with colors on the color handbook.

 Step 6

Repeat the whole process for more accurate results.

Measuring Soil pH using a Soil pH meter

This is usually quite straightforward because of how easy to use soil pH meters are

Step 1

Water the plant so that the soil it is growing on gets wet or moist. Let it sit for about 20 minutes.

Step 2

Insert the probe of the soil pH meter into the soil for about two minutes.

Step 3

Read the meter for the pH value

How to test for Soil pH using the Luster Leaf Rapid Kit

The Luster Leaf test, unlike other tests, uses a capsule to test for soil pH. It merely involves mixing a given amount of water with soil then adding the capsule.

After mixing thoroughly, note the color change then compare it with the accompanying color scheme.

The color comparator has specific pH values marked against whatever color you get after mixing well.

It is a relatively easy and fast way to determine the soil pH. It, unfortunately, doesn’t cater to other parameters such as soil moisture or light.

How to use a digital soil pH tester 

We bet by now, you understand why you need to test the soil pH. You bought your digital soil pH meter and are set to test the soil pH. However, you don’t know how to start.

Well, a digital soil pH meter is as easy to use as one, two, three. You will notice that your digital soil pH meter has a long probe attached to the head where the meter is.

All you have to do is insert the probe into moist soil for one to two minutes and check the reading on the meter. Easy, isn’t it? You bet it is!

How Accurate Are Soil pH Meters/Testers?

The accuracy of a specific soil pH meter will rely on the quality, pH range they cover, and the method of use.

Tests covering a broad range tend to give reasonably inaccurate results for soil pH. Seeing that soil pH usually ranges between five and eight, a strip with a long-range won’t give you the accurate results you desire.

One of the most familiar complaints you’ll see about most soil pH meters or tasters is that they aren’t as accurate as expected when they bought them.

To some degree, some can give quite unreliable and inaccurate results. That would be down to the quality being substandard. However, a good percentage are accurate and provide near perfect and believable results.

Sometimes, when you test for the pH but see highly inconsistent results or no change on the meter, you might be doing it the wrong way. Most users don’t get setting the meter right at first, which leads to inaccurate results.

A faulty meter can give you very inaccurate results that will have you doubt any future results the meter gives you.

Therefore, you have to ensure you check the meter every time you want to start a test.

Soil pH Ranges that your plants need

Most plants have their optimum pH between 5.0 and 8.0. However, plants are very adaptable and can teach themselves to grow in the soil of whatever pH.

  Plant  PH range  
Maple6.0-7.5  
  Lemon  6.0-7.5  
  Walnut  6.0-8.0  
  Potato  4.8-6.5  
  Asparagus  6.0-8.0  
  Garlic  5.5-8.0  
Tomato  5.5-7.5  
  Carnation  6.0-7.0  
  Tulip  6.0-7.0  
  Petunia  5.5-6.0  
  Morning glory  6.0-7.5  
  Lupine  5.0-6.5  
  Hibiscus  6.0-8.0  

Final Thoughts

We hope by now, you have decided on the best soil pH meter and tester. If you thought that soil pH doesn’t influence plant growth, well, we hope we have changed your mind.

Most of the products on our list such as the Allotpower soil meter and the GainExpress soil meter, are digitized soil pH testers.

Their digital approach makes it easier to test for the pH as well as the soil moisture level. In that way, you will know what nutrients your plants are lacking.

You can start that house garden as long as you remember to test the soil pH with either of the meters and testers we have discussed here. Good luck!
