Imagine being all excited about growing new flowers or some exotic looking plants in your garden only to see them growing weak or not growing at all. You can water and nourish your plants as much as you want but if the soil in which they rest is not in the perfect condition then no amount of nurturing will fix things.

So how do you find out if your soil is healthy? You test it with a soil ph tester. Some soils are just too acidic for certain types of plants to grow while some may be too basic.

To make sure you are planting the right seeds and also to find out what kind of fertilizer the soil needs, you must get a pH tester. This little device does an excellent job of detecting the amount of acid or alkaline in the soil and can give you the most reliable results possible.

We have put together a list of some Soil pH testers and also a guide for you so that you can now fix up the soil and grow that beautiful garden you have always dreamt of.

Beginners Guide to Buying the Best Ph Soil Tester

If you really want to know more before purchasing a soil tester to test the pH level of the soil you are planning to work with or already have in your garden then the following contents are going to make things easier for you. But before we get to the factors which need to be considered, we will explain to you why you need to test your soil for its pH level.

So, why do we need to test the soil and how does a soil pH tester help?

First of all, if you remember we learned all about the pH level of water in school during chemistry classes and maybe if we weren’t all interested in gardening or agriculture, we wouldn’t really bother much with all that information. But yes, after all those years we are back to that topic because we chose to invest some time in gardening or farming or even in keeping indoor plants at home.

See, just like water, soil has its own pH level and it plays a very crucial role in the health of your plants. Elements like calcium in the soil can make the soil quite basic (meaning it will have a higher pH level) while too much of phosphorus can make the soil acidic.

If the soil is too acidic it can be harmful to the plants and even prevent growth to some extent, whereas the soil is too alkaline can also be bad for the plants. To test these levels you will need testers because you cannot determine anything by seeing or feeling the soil. Even the dust from miter saw can make a difference ir soil’s ph.

Types of Testers:

There are mainly 3 types of testers that could test the pH of the soil: electronic tester, pH strips and dyes with colors. The best option or should we say the most convenient kind of tester is the electronic tool because it gives you precise and accurate readings when compared to the strips and dyes. The strips follow next, with the colored dyes being the least accurate.


Factors to Check Out When Picking a Ph Soil Tester

Display

If you going to buy an electronic tester then it will have a display with a dial inside and some markings that will read the different levels of pH in the soil, you need to make sure that the markings are clear and easy to understand.

Size

A small and compact sized tool will work best for those who wish to use the tester for their indoor plants and small plant tubs. However, small size does not mean that the tester should be too fragile or not sturdy enough to be used on the farm or in a big garden.

Durable

Electronic testers have probes or rods which need to be inserted in the soil for the tester machine to detect the pH level properly. The machine itself must be well built but even then the probes need to be strong and very sturdy.

Usually, customers complain that the machine worked fine but the probes got damaged or broke as they tried to push it in the soil. Of course ,you should not try to force it in if you see that the soil is too hard or rocky, but the machine should also feel durable and well constructed either way.

Waterproof

This is very important because the probes that will go in the soil might rust as soil has moisture. It isn’t advisable to keep the probes inside for longer than 10 to 15 minutes but if the probes aren’t built well, they may start to show signs of corrosion even before that.

Versatility

Most of the soil ph testers that we have reviewed for you are 3-in-1 tools where you can also test your soil’s moisture and sunlight level. This is more like a complete package because along with pH level you must also find out if the soil has enough moisture and gets the right amount of sunlight for the plants to grow well.

When you know the level of moisture in the soil you can tell when or if the soil needs to be watered. Dry soil isn’t healthy for plants and can cause plants to wilt or just die. Among the basic things needed for a seed to generate or a plant to grow healthy, is sunlight. If the soil does not let enough sunlight to penetrate through then germination might not happen in the right manner.

Keep in mind that not all plants need sunlight to germinate but the majority of them do so if you are working with the common kind of seeds and plants, sunlight is very much required. In short, to test the overall health of the soil, you will need to test more than just its pH level. And getting a tester that tests two or more things on the list saves you the hassle and extra cost of buying separate testers for each test.

Maintenance

No matter how high grade your soil pH tester is, it will sooner or later fail but you can prolong its life with proper care and maintenance. The testers usually come with manuals that tell you how to take care of the device but some general rules include wiping the probe immediately after use, not leaving the probe in the soil for long and keeping it away from harmful substances.

Depending on the model, the probes may need replacements so keep a check on that.


How to Test the pH Level of Soil?

The best pH range for most plants is from 5.5 to 7.0. However, some plants are adaptable and grow just fine at a level outside this range. In this article, you will find out how to test the pH level of soil and what can you do if the level is not as desired.

How to Test Soil pH Without a Kit

It is the DIY era. Almost everything can be done at home without calling a professional or using special tools. To test the pH level of soil yourself, just add half cup of vinegar to it. If it bubbles with a hissing sound, it proves you have alkaline soil with a pH between 7 and 8.

If it doesn’t bubble, add distilled water to another patch of soil until it is grubby and add half a cup of baking soda. If it now bubbles, you have acidic soil with a pH between 5 and 6.

No reaction of soil in both experiments means it is neutral with a pH level of 7.

How to Test pH Level of Soil with a Test Probe

For this purpose, you need to make a 2” deep hole in the soil. Fill this hole with distilled water until the hole is muddy and put in a clean test probe. Take it out after 1 minute to see the reading. If the reading is 7, it indicates neutral soil. A reading greater than 7 indicates basic soil, and a reading lower than 7 indicates acidic soil.

However, you cannot rely on a single test. Repeat the test several times at different spots and take the average to determine the final pH level.

How to Test Soil pH with Paper Test Strips

For this purpose, you need to get a litmus paper. Mix around 3 tablespoons of soil with distilled water, dip the reading end of the litmus paper in the muddy soil mixture for about 30 seconds, take it out, and clean the dirt with distilled water. Compare the color of the paper with the color codes on the test kit to find out the pH level of the soil. Remember to choose the closest color from the kit if it does not exactly match any.

What Can Be Done If the Soil Is Alkaline?

If your garden soil is alkaline in nature, there are two ways to fix it. Either use the plants that are not affected by the alkalinity of the soil, or decrease the pH level.

For the latter, you need to add a cup of organic material like peat moss or decayed leaves. Then, retest the soil to find out its new pH. If you get a decreased pH level but it’s still higher than what you want, you can keep adding the organic matter.


FAQs – People Also Ask

Can these testers be used to check the Ph level of water or other solutions?

No, we do not recommend using any of these testers for any other use except for testing soil. Even if it is possible you are advised not to.

How often should I adjust the meter?

You should regulate or adjust the meter after every use so that your next readings are accurate.

Why do I have to leave the probe in the soil for 10 minutes?

The time will depend on the particular tester but in general most electronic testers with probes need to be left in the soil for around 10 minutes to give it time to detect and analyze the soil. If you pull out the probe or read the markings too fast then you might risk not giving the machine enough time to collect the right results.

What is the pH range on these testers?

Usually the electronic testers read from 3.5 to 8 for pH level. The 3-in-1’s that also test moisture and sunlight have a dial reading of 1 to 10 for moisture and 0 to 2000 lux for sunlight.

How far deep should I stick the probes in the soil?

You will be asked to push the probe in anywhere between 2 to 4 inches. This is the standard depth for the electronic testers mentioned in this list. It might vary from model to model.

Conclusion

If you are keen on fixing up your soil to grow beautiful flowers or plants or maybe you love farming and want to grow fresh vegetables, then you must definitely have a tester around to check the quality of the ground you will be working on. These items are pretty affordable and carry more value than their price in terms of usage and necessity.

If you are planning to raise plants in your home garden or big fields, the first thing you ought to do is check the soil’s pH level through any of the methods described above. In case you are not lucky enough to get acidic soil, you can push luck your way by putting organic matter into it. Otherwise, you can grow plants that do not necessarily require acidic soil to grow.
