The 10 Best Soil pH Testers to Improve Soil Condition

Maintaining a healthy garden and plants is a task that requires considerable care and effort. There are numerous tips and tricks that can make gardening easier. A balanced pH level is just one of many.

Although there are various natural methods to check soil acidity, we strongly recommend using one of the best soil pH testers available.

To make it easier, we prepared a detailed list of the 10 pH meters we consider to be of top quality and worth your attention.

Healthy soil means a healthy harvest, so keep reading to get the info you need.

What’s pH?

Understanding pH is really easy. Just think about it as a degree of acidity that can have any value between 0 and 14.

If the value is lower than 7, then the soil is acidic and if it’s higher than 7 the soil is considered alkaline. Additionally, a value of precisely 7 represents a neutral soil type.

This value can help you modify the soil in your garden to meet the plant’s specific needs. Some require a more acidic environment, while others require a more alkaline environment to thrive.

Ultimately, this is the reason many experienced gardeners recommend testing the soil before planting.

What are the Key Features of a pH Tester?

Precision

Your pH tester must be precise to provide accurate measurements. Most of the testers can measure between 3.5 and 8; however, there are some whose range can differ by 1-2 points.

Never ignore the instruction manual, as it may contain valuable information that is essential for obtaining the best readings. Sometimes, you’ll need to keep the meter on the ground for a certain time frame, and at other times, you’ll need to gently shake the probes to get them started.

For optimal results, place the meter close to the plant’s roots to obtain a deeper reading, rather than just the surface of the soil.

Depth or Length

There are 2 types of probes in terms of design. They can either be with one or two metal probes. The metal can be copper, silver, aluminum, or a particular metal mixture.

Unlike construction metal, the length of the probe is a crucial feature when selecting the right option. A longer meter can help you reach the deeper layers of the soil, where you can get more accurate readings of its condition.

By following the instructions, you can get the most accurate readings and prepare your soil for any endeavor.

More Functions Available

Some meters are specifically designed to test the pH value of the soil, while others can also test additional conditions – these are referred to as multi-functional devices.

They can measure the level of moisture and light your plants receive. This type of device can bring more value, as it offers additional functions at an affordable price.

Compactness

A lightweight probe is a good probe! It can be used both indoors and outdoors without additional effort and preparation. Additionally, remember to get one that’s made of durable materials and can last for many years.

Power Source

Most of the options we presented in our article don’t require a battery, and they’re easy to use. However, other variants require batteries or an alternative power source.

It’s really up to personal preference what kind you want to use. Our detailed list examines the best options, so whichever you choose is acceptable.

What about Accuracy?

We mentioned previously that precision is one of the key features to look for when purchasing a pH meter.

But, how precise are they? Every professional gardener or expert advises pH soil tests before planting.

You can conduct the testing in a laboratory setting or use a testing device, such as the ones we’re discussing.

Although lab testing is undoubtedly the most precise option, it’s also more expensive and less convenient. That’s why practical gardeners use pH meters that can give instant results with a high level of accuracy.

To obtain the most precise readings, ensure your soil is not too dry and consider adding distilled water before taking the measurement.

If possible, use a meter with an accuracy of ±0.2 to achieve the best results.

How to Test the Soil?

First, make sure you turn on the probe and clean it with distilled water. Use a clean towel to gently dab away any remaining water droplets, but avoid rubbing the probes, as this can cause damage.

Furthermore, ensure that the soil is not too dry; adding some water will help soften it slightly. Inserting the probe in hard soil can cause physical damage.

It’s essential to calibrate the meter. Some devices are pre-calibrated, and for other meters, consult the instruction manual.

As soon as the probe is deep in the soil, you have to wait for a while to get an accurate reading. The time frame usually depends on the type of probe, so double-check the instructions.

Finally, if you decide to use testing strips instead of a meter, always follow the instructions to the smallest detail and consult the color chart to get a precise reading.

After each use, clean the meter thoroughly and have it ready for the next use. 

What can Influence Soil Acidity?

Many factors can affect the acidity of the soil, and some of the most common ones are:

• Rain can influence the soil to become more acidic due to chemical processes that happen when rain mixes with the soil.

• Plants such as alfalfa, soybeans, and clover can also decrease the soil’s acidity, as they consume more cations than anions. This process encourages the release of H+ ions, which contributes to the acidity.

• Topsoil can be more acidic than the lower layers, and that’s why it’s important to measure lower in the soil to get accurate info.

How to Adjust the pH Level?

Depending on the results of the measurement, you might need to adjust the soil pH. There are a few ingredients that can help you do this; however, whichever you use depends on how the soil needs to be modified.

If you need to lower the pH value, you can add sphagnum peat, granular sulfur, fertilizer, aluminum, and iron sulfate. These are all good options if your plants thrive in a more acidic environment.

On the other hand, if you need to make the soil alkaline, you can use limestone or potassium carbonate to get the best results.
