Buying Guide

You’re most likely looking for a soil test kit as you’re not happy with the growing results you currently have. It’s important to be able to identify issues and make changes. To do that, you not only need a kit you can rely on but one that gives you the information you require to take proper actions. In this guide, we’ll be going through all the key features, so you know what to look for. In the end, we’ll answer some FAQs to clear up any queries you may have.

How to pick the best soil test kit?

10 Best Soil Test Kits – Achieve the Balance of Nutrients!

The first thing you need to know is what type of kit you’re looking for. We’ll go into that in more detail immediately below, but there are key differences. This includes being able to test different nutrients, moisture, sunlight, and pH. Beyond that, you’ll also want to look at how easy they are to use, what recommendations they give, how accurate the results are, and also how fast the process is. When you take all this into account, you can start to build up a picture of the best soil test kit for you.

Type

There are a few different types of test kits, but they can be mainly put into three categories.

3-in-1 tests – Testers, such as the Sonkir Soil pH Meter 3-in-1 Kit, are generally probes that can measure the pH, moisture content, and sunlight. They offer rapid results but aren’t quite as accurate as other methods. It’s ideal for those wanting quick and easy tests.

Chemical tests – These kits use strips or containers to measure the pH of the soil, which is perhaps the most important measurement. The tests are usually exceptional quick and involve testing the color of the chemical reaction against a chart. For example, the Luster Leaf 1601 Rapitest Test Kit is a great choice here.

Lab tests – Products such as the MySoil Soil Test Kit are going to be the most accurate and detailed method. This is where you take a sample of your soil and send it away for analysis.

While you get the benefits of accuracy, the lab tests are usually a little more expensive and take more time.

What does it test?

It’s important to know the pH of your soil, as if it’s too acidic or alkaline, it could damage your plants. All the kits we’ve looked at here will test for it. Along with pH, you may want to know that nutrients are within the soil.

The most important are the macronutrients like nitrogen (N), phosphorous (P), and potassium (K), and they are vital for plant growth. The Luster Leaf 1601 Rapitest Test Kit is great for measuring all of the above and gives you vital information.

If you want to test the micronutrients such as calcium, magnesium, and zinc, you’ll probably need a kit that you can send away, such as with the MySoil Soil Test Kit. This will give you a full breakdown of everything within your soil.

Package content

10 Best Soil Test Kits – Achieve the Balance of Nutrients!

Each type of kit will come with different things within the package. For the test kits that you send away, you’ll most likely get a sample jar and a scoop to complete the process. Some will also have a nutrient absorbing capsule that they can then test. Additionally, you should have a pre-paid envelope included so that you don’t have to worry about any postage costs.

If you’re getting a chemical kit, you’ll want to know how many tests you’ll have in total. In this instance, the Garden Tutor gives you an impressive 100 strips, which allow for a lot of testing to be done. The 3-in-1 devices come ready to use, and you don’t need anything else to do the testing.

Instructions

Not everyone is going to be familiar with how to test soil, so it’s important to have well-written instructions, so you know what you’re doing. We were impressed with all 10 of the kits here, with the Whitetail Institute Laboratory Soil Test Kit being a great example with simple and easy-to-follow instructions.

Every test is going to be a little different, and therefore, it’s always wise to follow them. This is especially true of the lab test kits as these are a one-time use product, so you don’t want to waste your money by getting it wrong.

Fertilizer guidelines

An impressive aspect of many of these kits is the guidance you get. The Luster Leaf 1601 Rapitest Test Kit is a great example of this. Not only does it give you the preferred pH level of 450 plants, but it will also give you fertilizer recommendations depending on your findings.

The MySoil Soil Test Kit is brilliant for giving you a detailed analysis. This includes fertilizer recommendations that allow you to take precise steps for better plant growth. Having this information can be vital, especially if you’re starting out on your plant growth journey.

Accuracy

Each type of kit is going to give you a different level of accuracy. The 3-in-1 kits with the probe are perhaps going to be the least accurate when it comes to pH. The best ones aren’t out by much, but this isn’t the best idea for those wanting absolute precision.

If you want to have the most accurate results, you’ll need to use a kit that you can send away. The downside here is going to be time.

So, if you want a mixture of accuracy and speed, the chemical kits such as the Luster Leaf 1605 Digital Soil Test Kit can be a good compromise.

Fast results

We mentioned it in the above section, as speed has a big correlation with accuracy. In terms of these kits, usually, the faster you get the results, the more inaccurate they’ll be. The 3-in-1 tests are rapid and will be able to give you an instant gauge on that pH level, moisture content, and light.

The chemical tests are going to be a little slower, but not by much, and you shouldn’t have to wait too long. The lab tests obviously need to be posted out and then analyzed. Most companies will promise to have your results back in about 7-10 days.

Prices

10 Best Soil Test Kits – Achieve the Balance of Nutrients!

Along with the price, you should also have a look at what you’re getting for your money. The 3-in-1 kits, such as the Sonkir Soil pH Meter, can be used time and time again and only cost around $15.

You should be looking to pay a similar amount for testing strips such as the Garden Tutor Soil pH Test Strips. Digital test kits can be a little more expensive at around $30, as you get that extra level of usability.

For those lab kits, you can expect to pay around $30, which has everything included. The MySoil Soil Test Kit is around this figure. It may seem a little more expensive, but you’re getting plenty for your money with detailed analysis.

As you can see, the prices don’t vary by much, so choosing the right one should be much simpler. Just remember to pick the proper type that matches your needs.

FAQ

It’s best to take a proactive attitude to soil testing. It makes sense to find out if your soil is healthy before you start planting. That way, you can have full confidence that your plants are going to be as healthy as possible before you start growing them. Some may take a more reactive approach as simply try and solve issues where they see them, which is fine. While this can be less exhaustive, it means you can waste time growing plants in unfavorable conditions. Once you have the right levels, then it’s a good idea to check your soil every few years to see if anything has changed.

This will depend on what type of test kit you have, but one important thing to keep in mind is that you shouldn’t presume how to use it. That way, you may skip crucial steps that are required for the process. It’s always the best idea to check the instructions thoroughly. The likes of the test strips and the probes are going to be the simplest to use. Along with checking how they should be used, it’s also a good idea to read up on the results. Not using these tests in the proper way could lead to misreading the results, which, in turn, could lead to you making changes to your soil that aren’t required.

Each device and test have their own waiting time. For the pH tests, you’re going to get these results back almost instantly in most cases. When it comes to other types of tests, you may have to wait for the soil to settle and dry before you get results. The lab kits are going to have by far the longest wait of all, as it will probably take a little over a week. Sometimes it’s best to be a little more patient, so you have the highest levels of accuracy.

Our Verdict

We looked at many brilliant testing kits, but our highest rated one was the Luster Leaf 1601 Rapitest Test Kit for Soil. It’s a chemical test that can show accurate results not just for pH but also for the most important macronutrients. It’s the best solution for anyone looking to avoid a long wait.

Are you looking for a quick and easy-to-use device? If so, you can’t go wrong with the Atree Soil pH Meter 3-in-1 Tester Kit.

If you don’t mind a little wait or want in-depth results, perhaps the MySoil Soil Test Kit would be perfect with its excellent accuracy and detail.

All of the 10 options we looked at here are fantastic, and finding the right one will depend on your needs, the importance of accuracy, and how quickly you want the results. All that you need to do now is choose the best soil test kit for you and take the first steps to amazing plant growth.
