Our Comprehensive Buying Guide



Given that there are so many options available on the market, how can you make sure you choose the best home soil test kit for your plants? Continue reading to find out more about these products and make sure that, no matter which one you choose, you will receive professional results for all your plants.



Mail-in or at home?

Many of the products you will find on the market today allow you to test your soil in the comfort of your own home. Although these items are more convenient and easy to use, they require knowledge in the field of gardening. They do come with clear, step-by-step instructions but they will take some time to be properly calibrated.

You will also need time to learn to read and properly interpret the results so that your plants receive the best care. The good thing about home kits is that they provide almost instant results.

Mail-in products provide improved accuracy in terms of results. You will only have to send a sample of your soil and a team of professionals will run all the tests for you, providing the information you need to properly look after your plants.

The main disadvantage is that you’ll usually have to wait anywhere between a couple of days and a week until the results become available, wasting precious time.

And, since each plant requires different lighting and watering conditions, mail-in test kits are not a feasible option for those who want to grow different trees, fruits, veggies or flowers.


Number of tests

Many soil tests for gardens come with several individual tests, usually a complete set for each of the tested elements. You need to make sure the product you’re purchasing has enough tests for your needs or buy them in bulk.

Don’t forget that some elements will be tested more often than others, so you’re also looking at replacements. In time, all the extra supplies you’re buying will add to your costs, turning gardening into an expensive hobby.

There is also the option of electronic or mechanical devices that measure the most important parameters of soil without requiring additional supplies. They are usually lightweight and portable and provide accurate results in a matter of seconds or minutes.


Is soil the only thing that needs to be tested?

While soil testing is an important element to make sure your plants receive the optimum combination of nitrogen, phosphorus, and potash, there are other things you need to take into account, such as the soil pH, sunlight, and moisture amount.

All these elements combined ensure proper growth for your plants, supporting them throughout their development cycles, from seedling to bloom. Thus, if you want to test more than the soil, you’ll need to either invest in additional accessories or in one single device that can measure all these parameters together.

According to recent studies, when used correctly, moisture meters can reduce outdoor water usage by more than 50%, which further translates to cheaper bills and the optimum amount of water for all your plants.



Frequently Asked Questions


Q: How do soil test kits work?

As we previously mentioned, there are various types of soil test kits, each measuring different elements and reacting to different compounds and stimuli.

If we’re referring to 3-in-1 products, there are a few simple steps you need to follow before reading the results provided by them and understanding what needs to be done next for your plants.

If your kit measures the soil pH, moisture level, and sunlight exposure, you will have to insert the probe into the soil about 2-4 inches deep and adjust its position until the pointer on the dial swings slightly.



Q: How do you use a soil testing kit?

The instructions depend on the type of soil kit you opt for. 3-in-1 products that are more convenient and affordable come with step-by-step instructions on how to use them to get the most accurate results.

The first step usually tells you to switch to the type of position you wish to test – moisture, pH or light. Then, you should insert the probe into the soil about 2-4 inches. Adjust the position of the probe so that the pointer on the dial swings slightly, and then wait anywhere between 60 seconds and 10 minutes to read the dial.

After your testing is done, remove the probe from the soil and use a clean wipe to remove excess dirt and debris.


Q: Do soil test kits expire?

Many soil fertility and pH tests are affordable but this doesn’t mean they will last forever. If you opt for a home kit, you will have to buy replacement chemicals or reagents as they expire.

If you’re opting for 3-in-1 devices that give you the results on the spot, you won’t have to worry about their expiration date. Most of these devices use other systems to test moisture and pH and don’t require you to replace substances. However, these items might not be the best solution if you’re a beginner as they are a bit more complicated to set up, read, and interpret.


Q: What are the different types of soil tests?

The analysis of soil is conducted for a large variety of reasons. However, the most widely conducted soil testing is designed to estimate the available concentrations of plant nutrients to determine the necessary amount of fertilizers and water used for agricultural purposes. Other soil tests can be conducted for engineering, ecological or geochemical investigations.

Most do-it-yourself kits test for three major nutrients (nitrogen, phosphorus, and potassium) and soil pH. These tests can be usually purchased from farming cooperatives, gardening stores, and university labs.

Electrical meters can measure soil acidity, water content, and nutrient content. You can also opt for laboratory tests conducted by specialists that deliver more accurate results but take up to 10 days to complete.


Q: Why is it important to test your soil?

Each plant is different regarding its soil pH and nutrient needs. Soils also vary considerably in their ability to meet the plant’s nutritional needs, depending on various factors such as soil parent material, texture, structure, biological activities, climate, current growing conditions, and others.

By testing your soil, you will be able to adjust the number of nutrients your plants receive for healthy growth. Other benefits of testing the soil include minimizing the fertilizer amount used which further translates into cost savings and a greener planet, as well as reducing soil water by around 50%, according to a study recently conducted by the experts from the University of Florida.
