The 5 Best Soil pH Tester – 2021 Buying Guide

Soil pH Testers

If the soil is acidic, neutral, or alkaline, one of the most important factors for whether a plant will thrive or not is.

Even the Soil pH Testers may have disastrous effects on your plants being a little off in either direction.

That’s why using the right soil pH tests is so crucial to ensure your plants are getting the nutrients they need to be happy and safe.

What is Soil pH and Why is It Important?

The main reason soil pH is so important is that it determines the availability of all the plants needing the nutrients.

A pH of 6.5 is usually optimal but this number varies depending on the species of the plant because they all have different needs.

If the pH is too low, the soil is acidic and there are fewer nutrients, such as phosphorus, available while other things can accumulate and become toxic. Soil that is too acidic for beneficial bacteria is not a good house, either.

On the other side, high pH soil is alkaline, which removes access to iron, manganese, copper, phosphorus, which zinc from the plant. Iron is of great importance to all plants, but especially important for evergreens.

How to Test Soil pH with pH Meter?

Every tester functions a little differently, but they do have a lot in common. Since most of these meters are using probes, a general process for how to use them is here.

1. Clean and Calibrate

Turn on your meter, and let it get a little warm. This usually takes approximately 30 minutes but to be sure, you should test the specific instructions for your meter.

First, clean the electrode by removing it if possible from the storage solution, and rinse it with distilled water.

Once the electrode has been rinsed, blot dry. Don’t rub it because you might damage some delicate membranes or scratch the surface of the metal. If it’s not enough to clean the distilled water, check your tester ‘s manual and use the cleaning solution they recommend.

2. Using Your pH Meter

It’s not always as easy to use your tester as just to push the probe into the soil. While the instructions that come with your meter should always be followed, here’s one way to get good results.

Begin by digging out the top two inches of soil from different locations around the planting area. That includes different parts of the bed and different depths of soil. The pH in any garden will vary widely from place to place and from one layer to another.

Place all the samples you collect in the same bowl, thoroughly mix, and be careful to avoid any rocks as they may harm the sample. Measure around two tassels of mixed soil in a clean tub.

Fill the soil with distilled water and seal it into the tub. Turn on the meter, and insert it into the soil using a clean probe. Twist it to ensure you have good touch all the way around and keep the probe away from the container ‘s rim.

Next, you need to let the probe settle down. How long depends on the manufacturer but can range from 60 seconds to 10 minutes or more anywhere. Note the read after the allotted amount of time has passed.

If you are using a test kit with test strips or capsules encoded in color, be sure to obey the instructions with care. For some of these sets, various color control media are applied to the soil and triggered with a couple of drops of water. You’ll be given the pH amount by comparing the final color to the included chart.

3. Clean up

Proper cleanup is important because next time, it makes everything easier. In distilled water, rinse the electrode and blot dry. Then, keep it away till next time. Consult your manual for best practices on storage.

How to Raise and Lower Soil pH?

Before making adjustments one important thing to keep in mind is that not all plants prefer neutral pH.

Plants such as blueberries and azaleas, for example, thrive in acidic soil while some plants, such as lilies and hyacinths, prefer alkaline. Make sure that the soil is adapted to what your plants prefer.

The pH-scale ranges from 0 to 14 with a neutral pH of 7. About 7 is considered acidic; above 7 is considered alkaline. Most plants prefer slightly alkaline pH between 6 which is slightly acidic, and 7.5.

You can either choose plants that prefer the soil you have or change the pH of the soil to suit your plants if your pH is off.

How Accurate are Soil pH Testers?

Although they may not be as accurate as having the soil sent to a laboratory, soil pH testers can provide you with reliable and consistent results. There are a variety of things you can do if you want to get the best results possible.

First, make sure you make accurate use of the tester. Carefully read the directions, and follow them exactly. Place the probe deep enough, and wait long enough to get an accurate result.

Next, make sure you have your tester cleaned and stored properly. Samples should be washed both before and after use, using distilled water. When washing, always be careful and be sure not to rub the probe too hard because it could cause damage.

Finally, if recommended by the manufacturer, calibrate your tester and make sure you are using the buffers that they suggest. This usually involves calibrating the probe to a liquid that is neutral, acidic, and alkaline.

Final Thoughts

Proper pH is important to ensure your plants grow to their full potential. If you find the leaves turn yellow or any other irregularities, a good place to start troubleshooting is to test the pH of the soil.

It ‘s important to use the best available soil pH meter to get the most accurate results, particularly if the soil is being treated to correct the pH.

If you’ve done treatments to raise or lower pH, make sure you start with an accurate reading of the foundation. Then, after diagnosis, test regularly to make sure you are having the right results. This can prevent any over-corrections that may lead to other problems.

Bear in mind, too, that several of the items we chose the test for several factors so you can really check your soil ‘s overall health and make sure your plants get what they need.
