When I started gardening I planted whatever wherever. Some plants thrived; many died. Finally I learned the importance of testing the soil - I found out what micronutrients I lacked and how my pH levels were out of whack. After following the detailed recommendations, my crops thrived. I could have saved myself so much money and time if I had done this earlier.

Do YOU know if your soil is missing nutrients? Perhaps you have plants that refuse to grow even though there’s another one of the same type just yards away! This could be due to an imbalance in your soil, and a test kit can help solve this problem.

A good soil test kit is able to tell you if your soil's nutrients are off, and you can then correct it to get healthy soil, beautiful lawns, and thriving plants all season long.

Our Top Pick

Our winner for today is Soil Savvy by Soil Test Kit—it’s straightforward and will analyze all nutrients and pH in your soil. Along with your results, you’ll receive recommendations for fertilizers, both organic and synthetic. 

Here is an example of the results you get from Soil Savvy. This should give you an idea of what to expect from the results you’ll get from laboratory soil test kits.

Why It's Essential to Test Your Soil

Sadly, planning or maintaining your garden isn’t always as straightforward as it may seem. You know how it is. You plant your seeds and wait, only to find tiny shoots that won’t grow. Plants require nutrients to develop, just like we do. If you look closely at any fertilizer, you’re likely to see a few common ones like potassium, phosphorus, and nitrogen. However, there are other crucial nutrients such as calcium, which is vital for optimal plant health.

Before planting a garden, it’s important to get your soil checked. This way, you’ll know what you need to add, what you have enough of, and which kind of plants can thrive. It allows you to amend possible issues before they affect your vegetation.

It can also help you prevent over-fertilization, which can lead to erratic growth like root-forking in carrots.

Lastly, it’s crucial to check your soil to measure the pH level. If the soil is too acidic or contains excessive alkaline, certain plants will not grow. Of course, some thrive in an acidic environment, but most prefer a neutral range.

Types of Soil Tests

1. Soil pH

The primary measurement tested for is the soil pH level. You’ll find kits which exclusively look for this and others that combine it with additional data. For most plants, an ideal pH is between 5.5 and 7.0. However, research the plants you’re trying to grow to ensure you’re within the right range. 

2. Micronutrients

Micronutrients are elements like calcium, iron, magnesium, among others. These are also crucial for flourishing plants. Sadly, most home tests only look for the major nutrients such as nitrogen, potassium, and phosphorus.

3. Macronutrients

When working with fertilizers, you’ll probably notice an NPK rating. This is what tells you the proportions of nitrogen (N), phosphorus (P), and potassium (K) present in the fertilizer. NPK are the nutrients most plants require to mature and fortunately, they’re generally present in the soil already. 

Types of Soil Testing Kits

1. Chemical Tests

Chemical soil testers are relatively easy to use—you’ll receive everything you need in the kit. This usually includes vials where you place your soil, combined with water and a colored capsule. Each tablet represents a test for a nutrient.

You drop in the capsule, shake the vial, and wait as per instructions. Soon, the water changes color which you can then compare to the accompanying color chart. More advanced chemical kits are available, but these aren’t necessarily more accurate. 

2. Professional Soil Test Kits

Likely the best and most accurate are professional soil test kits. These require you to collect a sample of your dirt and send it to a lab where experts conduct an analysis. Since the labs have all the specialized equipment needed for precise results, this is the most reliable method. 

At the lab, they test for everything, including pH, N, P, K, and micronutrients. With most kits, you’ll also receive recommendations for improving your soil quality.

In saying this, its accuracy does depend on your ability to gather the dirt. You must harvest soil from different spots in your garden, then mix before letting it dry and sending it off to the lab. 

3. Digital Soil Testers

Digital soil testers are great if you want to conduct a quick analysis of your garden. These come in two forms. One includes a vial and one requires you to insert it directly into the ground. Although, the most accurate is the former. Keep in mind that most only check the soil’s pH level.

However, if you’re looking to check for nutrients, you’re better off with either a chemical or professional. 

Frequently Asked Questions

Should I test my soil before planting?

It is ideal to test your soil before planting. Some experts say ‘just plant it and see if it works’ , but knowing exactly what’s in your soil (or what’s NOT in it) will help you know if your plants will thrive and grow.
