The pH level tells you whether the plants you grow on your soil will get sufficient nutrients or not. Soil pH testers are of two types, electronic and chemical. Based on your preference and convenience, you should buy a good quality soil pH tester for your soil to keep yourself abreast of its health.

Buying Guide

If you are determined to get the most accurate results as far as the pH level of your soil is concerned, you must invest in a good quality and reliable soil pH tester. While older or popular brands do evoke a sense of trust and confidence, you can also try out testers manufactured by newer companies if you find them to have all the features that will help you get a fair idea about your soil quality.

Here are some of the factors you must consider while buying a soil pH tester.

Portability – Since you will most likely be using a soil pH tester in an outdoor area, you must try to look for a device that is portable. If you are travelling to your farmhouse which is several miles away from your home, you can’t move around with heavy equipment. While most soil testers come in compact sizes, you must opt for the one that suits you well. If you have an indoor garden area and you need a pH meter to check its pH level, you can buy a slightly bigger device.

Calibration – When you are considering buying a particular pH meter, you must make it a point to check its calibration settings. A calibrated pH soil tester results in the most accurate reading. You must also remember that some pH soil testers work best in certain environmental conditions. There are many pH meters that fail to take an accurate reading of the soil in a hydroponic garden. Then there are some meters that prove to be unsuitable for testing dry soil. So, before you invest in a soil tester, read the instructions that have been laid out for calibrating the tester.

Accuracy – One of the important things to check while buying a soil tester is the accuracy it provides. A soil tester that does not show accurate readings is not worth investing in. A reliable soil tester is one that observes and informs the user about the slightest fluctuation in pH level, temperature or moisture in the soil. Apart from buying a good soil tester, you need to do a few things to ensure that you get accurate readings. The probe should be in close contact with the roots and four inches deep inside the soil.

Durability – Soil pH testers consist of probes that help in checking the pH level in the soil. Inside the device, the probes must be transfixed in a sturdy manner. Since you will be inserting the electrodes into the soil, you have to ensure they are well-built and durable. If the probes are not made of good quality components, the various rough elements in the soil can damage them.

Waterproof – Since you will be putting a soil tester into moist soil, it would be better to invest in one that is made with waterproof material. Probes, which come in testers that are not water-resistant, tend to rust faster. Inferior quality probes also result in corrosion. If you have a waterproof tester, you can also use it to test the pH level in a particular liquid-based product. There are a handful of brands that manufacture high-quality waterproof soil pH testers.

Frequently Asked Questions

Soil pH testers work on a very simple mechanism. With the help of the pH test, one can measure the amount of hydrogen ions present in the soil. The testers, therefore, take the help of electrodes to attract ions to it. The methods used in both electronic and chemical tests remain the same. Once the electrodes on the tester attract the hydrogen ions, a reading is sent to the pointer which is responsible for providing information on the level of ions.

If you have a liquid tester and want to test the pH level of the soil with it, you can start off by putting some soil into a small container. After that, add chemical liquid to it and shake it gently. Keep shaking until you see a mild change occurring in the colour of the liquid inside the container.

A pH meter’s resolution is higher than a pH paper. That’s the reason the accuracy offered by the former is higher than the accuracy offered by the latter. A pH meter also proves to be more effective at providing more consistent or reliable measurements. Also, a pH meter is far more durable than a pH paper.

The process of using a digital soil pH tester is very convenient. All you need to do is to insert it inside the soil and wait for a few seconds to have a look at the reading. You can also make a mixture containing soil and distilled water and put the electronic device inside it to get an accurate reading.

No, soil pH testers are not designed to work on water. These devices are made to check the quantity of hydrogen ions present in the soil and not in water. That being said, some companies do manufacture soil pH testing strips that work on water.

It is important to know that even if you use a testing strip that is said to work on water, it won’t provide you with an accurate reading. You will come across a large number of soil sensors featuring a limited pH range. Therefore, if the acidity level in water in higher than the range covered by the sensor, it will go undetected.

A pH meter works only if it’s inserted into soil which is sufficiently moist. So you must not insert a pH meter’s probe into dry soil. If the soil is too dry, watering it before getting the probe inserted inside it would be a good idea. Do not insert the probe immediately after watering the soil. It is important to wait for a few minutes to ensure that you do not take the reading of soil that is too watery.

It depends on how frequently you use the tester. Most brands recommend calibrating a pH meter after every single use. However, that’s not necessary. To get accurate results, it would be sufficient to calibrate it once in 10-15 days. If your pH meter is not calibrated, you will not be able to get accurate measurements.
