[GUIDE] An Introduction to Soil pH Tester Kits
Testing soil will give you peace of mind, and maximum plant health and productivity
NOW THAT YOU HAVE the spot picked out for your garden and have it all cleared and ready to go, the next step is to determine the quality of the soil.
You can, of course, take a small sample and send it off to the UMass Soil and Plant Tissue Testing Lab for analysis. But this can take a lot of time and be a little expensive. A much better option is to use a soil pH tester kit and do it yourself.
So let's take a look at what you should be looking for in a soil pH test kit to make sure you don't waste your money. Before you rush out to the nearest garden center or department store.
Why You Need a Soil pH Tester Kit
In short, maintaining the proper pH balance of your soil is vital to the healthy growth of everything you plan to plant in your garden.
For example, if your garden has a high level of calcium in it, the soil will be more alkaline. On the other hand, if there is a high level of phosphorus in your soil, it will be more acidic.
Most plants require certain amounts of each in order to flourish. However, if the soil is too acidic or alkaline, your plants will not thrive and provide you with maximum harvest. This is the main reason why you need to buy a pH tester and keep a close eye on the pH balance of your soil.

Three Different Types of Test Kits
There are, in fact, a total of three different types of soil pH test kits on the market today, pH strips, pH colored dyes, and electronic pH testers. The issue with strips and dyes however, is neither of them is capable of giving you accurate results you can rely on. You also need to buy every test you intend to do.
This leaves only the electronic pH testers. Electronic testers are able to provide you with almost instantaneous results that, depending on the brand/model you buy. They give you accurate results you can rely on. Also ph testers in this category are reusable. All you need to do to reuse the tester is to clean the soil off it.
One thing to keep in mind if you have never used a soil pH tester before is to be sure that the tester kit you get comes with a very complete set of instructions. Not only should the instructions tell you how to use the kit, but they should also tell you how to interpret the results. After all, not much good having a series of test results if you have no idea what they mean, right?
The instructions should also cover how to calibrate the tester to ensure you get the most accurate results possible. The problem here is that if you don’t get accurate results or are not sure how to interpret them, you can easily end up over or under-fertilizing your garden. This could leave you with a garden that does not produce the best possible results or worse yet a patch of ground full of dead plants.
Look for a Test Kit that Does More
If you want the best results, look for a soil pH test kit that does more than just measure the pH of the soil. A good testing kit will allow you to run at least four different tests on your soil.
The pH Level - the pH level of your soil should be between one and fourteen on the scale, with neutral soil sitting in the middle at a solid seven. Once you know whether your soil is acidic (under 7) or alkaline (over 7) you can adjust the type and amount of fertilizer you need to use.
Your Soil's Conductivity - Electrical conductivity is used to determine the level of naturally occurring nutrients currently in your soil. Once you have these figures, you can more accurately determine how much more fertilizer your soil needs.
Your Soil's Temperature - Different crops need different soil temperatures in order to germinate properly. You need to measure the temperature at the level you intend to plant the seeds. Rather than at the top which would be of no value with regard to helping your seeds to germinate and flourish.
Most, if not all quality seed packages will tell you the optimum soil temperature for best results.
The Level of Light - Plants all have their own very specific needs when it comes the right amount of sunlight for proper growth. Some pH tester kits have a built in light meter to help you determine how much sunlight each area of your garden receives on an average day.
I would recommend you buy a separate light meter if the kit you choose does not have one built in.
Using a a Kit
Using an electronic tester is relatively simple. Of course, the best way to make sure you are using yours the right way is to read the instructions that come with it.
The good news is that most pH testers are very similar, here are a few basic tips that should help you get started. They are common to a wide range of brands and models based on my experience.
Here is a quick video that covers using an electronic pH test:

While this meter is used only to measure the pH of your soil, what attracted me to it is the fact it is so simple to use.
All you have to do is dig a hole in your garden that measures 3 - 4 inches across and approximately 5 inches deep. Fill the hole with water and let it drain out. Stick the tester in the soil and wait for the results, nothing could be easier.
