Soil quality is a major component of growing healthy food plots, as well as other things, such as gardens and yards. There are many different soil test kits available for everyone from the one-plot hobbyist to die-hard land managers. That’s why I sorted through many of the offerings and designated the best soil test kits.

How I Chose the Best Soil Test Kits

Naturally, where you live impacts the type of soil that lies there. Silt, loam, clay, and sand are the most common soil properties, and each of these take a different percentage of the soil composition ratio depending on geographical location. This impacts soil pH, and there are, of course, numerous soil elements to consider, including: macronutrients, micronutrients, pH (acidity and alkalinity), soil temperature, soil moisture, light availability, etc. But analyzing these things requires a soil test kit.

When comparing different soil tests, there are also various things to think about, including accuracy (most important), ease of use, results speed, price, and more. Different soil tests perform differently regarding each of these factors, and choosing the right one will depend on your priorities.

So, what’s right for you? The typical soil test types include analog, chemical, digital, laboratory, professional, and strips. Each one of these are best-suited for certain situations. Here are some of my top recommendations.

The Whitetail Institute Laboratory Soil Test Kit is a great option for those seeking the utmost accuracy in their soil samples. Obviously, it requires a pulled soil sample, completed form, mail-in effort, and a wait period. That said, for those with enough time, the accuracy of the results are incredible.

Fortunately, the typical wait time is one week. And once the results come in, these are easy to translate into in-the-field soil correction. Plus, it offers incredible customer service with the included professional phone consultation.

Key Features 

Near-instant results (20 minutes)

Four tests included

Price: $15

Pros

No lab needed

Good instructions

Easy-to-read results

Cost-effective

Cons

Must use distilled water for testing

Only has four tests

The Antler King Instant pH Soil Test Kit is an excellent offering. This test is one of the most accurate no-lab-required tests on the market. You get results in 20 minutes rather than a week or more of waiting.

In addition to the basic readings, it also includes a fertilizer utilization chart with 10 helpful hints for better food plots. Plus, the pH result readings are very easy to understand and interpret.

With only four tests included, that’s fewer than some options on the market, but more than others. If there are only a few small food plots to take samples for, or one large area with multiple spots to test, one kit will work. However, multiple kits are needed for additional areas.

Pros

Fast at-home results

The Garden Tutor Soil pH Test Kit Strips are great for those who prefer the test strip route. Obviously, these are less popular with the advent of modern soil test kit. That said, these still hold value, especially for those who have many different soil samples to pull on a budget. This allows the consumer to test more areas with less money. Even so, an analog or digital is better suited for increased testing.

This unit is calibrated specifically for fast soil pH testing. It does offer results as quick as 60 seconds, too. Plus, it comes with 100 strips, which will last much longer than many other test kits. Furthermore, it includes a detailed pH testing handbook with soil application charts.

Some soil tests don’t have as much range as this one, too. It tests soil between the 3.5-9 pH range. That’s beneficial for those likely to have soil at one extreme or the other. All said, this is a great option for those wanting test strips.

How to Choose the Best Soil Test Kit

Choosing the best soil test kit isn’t easy. That’s why I’ve sorted through many different products on the market, tested items, and made designations based on what they do best. I’ve done a lot of the hard work for you.

As with most product categories, product testing isn’t so much about apples-to-apples comparisons as it is determining what each option does best. Then, comparing those items to similar items that also do those same things very well. Once you group items in this manner, then it’s much simpler to accurately determine what is best-suited for a given purpose.

Therefore, when choosing the best soil test kit for you, it’s important to understand your needs, expectations, and timeline. Then, choose the soil test kit that best aligns with those three factors.
