How to Test and Measure Your Soil pH With a pH Meter

The first time I used a soil PH meter, I simply stick it to the ground and waited for the results. The problem with this technique is that you may not get an accurate result. If you want to know how to Test And Measure soil PH with a pH meter and get a more accurate PH result, I have some easy steps to share.

First of all, there are all sorts of Soil PH Meter available out there. There are test strips, dyes, kits, and old-school and digitalized meters that you can use.

I have a Dr. PH Meter. I like it a lot because aside from the soil’s PH level, it also measures the soil’s moisture, sunlight intensity, and the soil’s temperature. It’s very easy to use!

I prefer a digitalized electronic meter because it’s very easy to read and it displays the most accurate measurement among all types of soil PH meters.

It’s not a requirement to get a digital soil PH meter to get the most accurate result. What’s important here is the type of meter you have and the method you choose to test your sample.

Generally speaking, it’s simple and very easy to get a sample and test its PH no matter what type of meter you use.

Steps to Follow

  • Take a soil sample - you can get at least one scoop of soil from your garden or pot.
  • Make sure that the soil sample you have is pure. It shouldn’t have any rock, pebble, sand, leaves, or any debris. It is also best to get the portion of your sample from where the root is. This is to ensure that the result you will get is the most accurate.
  • Place the soil sample in an open container and add water. The amount of water should be the same with the amount of your soil. So if you got a scoop of soil, you should only pour a scoop of water on it.
  • Stir the soil for 5-10 seconds and then let it sit for 15 minutes.
  • After 15 minutes, stir the soil for another 5 seconds and get yours Soil PH meter.
  • Place the meter stick on the soil and wait for the screen to show how much PH your soil has.

Note: Always make sure that you clean the stick of your meter before and after use so that you won’t get confusing results.

Another way of testing the Soil PH with a Meter

Another easy way to measure your soil’s PH without using a container is by digging. The way I do it, I just dig a small hole in my pot or land area and fill it up with water. 

When it comes to the amount of water, 16-20 ounces will do. While pouring water in the hole, I start to mix and wait until the soil’s consistency becomes muddy and mushy.

I use a PH Meter with a needle or stick on it for this way of measuring. After 4 minutes of mixing the muddy soil, I stick the PH meter about 5cm deep to make sure that the tester gets enough samples. It should only take a minute for the meter to completely measure the soil’s PH level.

Other Types of PH Testers you can use 

Strip Test Soil PH Meter – if you are on a budge, this is perfect. It’s basically litmus paper on a strip that you can just dip on the soil mixed with water for about 30 seconds.

The color you get on the strip is comparable on the chart it comes with. It reflects the PH level of your soil. The problem with test strips is that the color it shows may be hard to read or interpret.

Chemical Dye Soil PH Meter – This is basically a PH test kit. You just have to get your sample and put it in the container and solution it comes with.

The color of the sample inside the container will change after shaking it, and that will help you determine the PH level based on the chart that’s part of the kit.

Knowing Your Soil’s PH Level

Now the meter you have may display the PH level of your soil in two ways. It could be from 0-14 or 0-100.

Levels 0-14 is the most common display on soil PH meters. The PH level of 7 means that your soil is in a neutral state. If your soil’s PH measure is below 7, it says that your soil has higher acid. If it goes above 7, it means it has higher alkaline.

If your soil scored a PH level of 0-5, it most likely has more aluminum, iron, and manganese. Those elements could be detrimental when it comes to some plants’ growth. It’s still best to keep your soil PH level neutral for most plants.

Understanding the right PH Level

Please don’t think that your soil PH has to be maintained with a score of 7. What you really have to consider is what kind of plant you have or plan to nourish.

Also, your soil PH measurement can be controlled. If you want your soil to have a lower acidity level, you may use the juice of citrus fruits on it like lime, orange, or lemon.

I know it sounds like it should increase acidity because these fruits have acid, but trust me! It does the opposite. It actually increases alkalinity!

Here are a few alkaline-loving plants:

  • Barberry
  • Crocus
  • Lilac
  • Buckeye
  • Ironwood
  • Honey Locust
  • Austrian Pane
  • Green Ash

If you want a soil with lower alkalinity, you can easily get any brand of soil sulfur from your favorite gardening shop like Arizona’s Best.

A few plants that prefer acidic soil are:

  • Azaleas
  • Daffodils
  • Rhododendrons
  • Heathers
  • Hydrangeas
  • Japanese Pieris
  • Wood Anemone
  • Bleeding Heart

When Is It Best To Test The Soil PH?

You can test the PH level of your soil anytime. I of course measure before I plant something new in my garden or pot.

Other than measuring the soil’s PH level before planting, I also measure it if there is a sudden change in the weather.

Rain can affect the acidity level of the soil. So you bet I measure the soil PH level in my garden the day after it has been raining.

If it hasn’t been raining, it doesn’t mean that you should not test your soil’s PH. I test mine every 3-5 months. I also plant a few vegetables, so that’s why I want to be sure that my soil’s acidity level isn’t going crazy.
