Types of soil pH Testers

Chemical soil pH tester

It is used to determine the baseline nutrient level within the soil. Once enough data has been collected, recommendations can be made for cover crops, fertilizers and make the amendments. This tester can be used used to determine the type of soil. Some plants need particular soil types to thrive, and timing is crucial when doing the tests, which is where this tester is applied.

Digital soil pH tester

The digital soil pH tester can be used to determine if you are at adequate, sufficient, deficient, depleted, or surplus for the three macronutrients, namely nitrogen, potassium, and phosphorus. Also, many use it to test the average pH and determine the pH at extreme levels. This type of soil pH tester includes a plastic dropper, test tube dock, four test tubes, a proprietary digital soil test module, and the color-coded nutrient test capsules.

Analog soil pH tester

This soil pH tester uses about two to three metal probes when testing different aspects of soil. When you place the probes in the soil, a natural electrical energy register is stored between the probes so that these non-electronic devices can store various things. Many analog testers can provide a rough estimate of the pH, the amount of sunlight received during the test, and the soil moisture. Some also test the general soil fertility.

Professional soil pH tester

The professional soil pH tester is an excellent option for those who do not want to skew the results. The soil sample is placed in a jar, provided, and sent to the laboratory in a sealed envelope for professional analysis. The results are then sent through email and can be found online.

Factors to Consider When Buying the Soil Ph Tester

Accuracy

It would be best if you look for a soil pH tester that is accurate. It is supposed to have a range when measuring within. Most of the soil pH testers can measure between 3.5 and 8, while some have a range, which is smaller or larger. You need to carefully follow the instructions that come with the soil pH meter, as they can give you the right idea of how to get an accurate reading on the device. For example, you may need to move the probes, keep them in the soil for a long time, or place them closer to the plant roots for best results.

Probe depth

The soil pH testers are designed in two ways: one or two probes. Typically, these probes are made of metal, such as silver, aluminum, metal amalgamation, or copper. Although the type of metal is not very important for the accurate reading of the soil, the probe depth is essential. If the probe of the soil pH tester is more extended, it will be the best because it will offer the best content of the whole soil section.

Design

The soil pH tester typically has one or two metal probes, measuring between 7 and 8 inches. Use the button below the adjustment dial to measure pH, moisture level, or light. When you place the probes in the ground, the needle pointer will move to the numbered gauge on a dial screen to display the correct reading.

Waterproof

When buying the soil pH tester, a waterproof feature is very crucial. The reason being, the probes must penetrate the ground. If it is not waterproof, the probe can start to rust in the soil moisture. Besides, if the sensors are not of good quality, the testing can cause corrosion.

Durability

Electronic testers have rods and probes that are inserted into the ground. This can allow the device to measure the pH of the soil effectively. The device must make sure the probes are durable. This is because you deep it into the soil. A lack of a well-built device can result in rods or probes damaged by soil elements like moisture.

Versatility

Some critical tests must be done to check the quality of the soil. This includes the sunlight levels and soil moisture levels. A soil pH tester, which can measure the level of sunlight and soil moisture, is the bonus. Make sure your tester is 3-in-1 to check the soil conveniently. You need to have a device that can perform all three tests instead of having one device for every test.

Number of Tests

Many soil pH testers offer several individual tests, usually a fixed number for each test. You are required to be careful when buying the tester to make sure you have sufficient tests for your requirements. Many of these products also offer different size options, so you can buy them in bulk if need be. And you may want to ensure you buy the replacement products. For instance, you can test an element more than others, and you will need to ensure you buy tests individually to correct the differences in tests.

Portability

It would be best if you look for the soil pH tester, which is compact and lightweight. This will make it convenient to carry around and use in all types of weather. Soil pH tester probes can be sensitive, though you may want a device that offers the best performance on your investment.

Power source

Most of today's soil pH testers are battery-free, so you can test the soil without connecting in AAA or AA batteries. However, there is some sold that require batteries. At the same time, the tests are battery-operated and more accurate. In the absence of scientific evidence on this issue, the jury is not yet present.

Maintenance

Regardless of how good the soil pH tester is, it can fail sooner or later, but you can extend its life with proper maintenance and care. Typically, testers come with manuals, which describe who to maintain the device. According to some general rules of the probes, clean it immediately after use, do not leave it on the ground for a long time, and keep it away from destructive substances. Depending on the product, the probe may need to be replaced.
