As with the Veroyi kit, this one also tests for pH, moisture, and light. Usage is also the same, select the desired switch first, then stick the probes into the soil.

How to Buy the Best Soil Test Kit

Testing your garden’s soil is the only way to know exactly what it can offer your plants, but there are so many soil tests available that the newcomer easily gets overwhelmed.

You need to understand the major goals of soil testing, which is to check the pH balance and macro-nutrient availability of any soil. With this in mind, you can keep an eye on the following important factors when making your choice for the best soil nutrient test kit.

1. Type of Soil Tester

The first thing you need to understand about soil testers is that there are three major types that you can use. They are chemical tests, digital tests, and professional testing services.

Each type of soil test has its advantages and disadvantages, so it’s left for you to first consider what you need to test for in the soil, and to then choose the most proper testing method for it.

Following is a closer look at each type of soil test.

Chemical Tests. This type of soil testing requires you to place a small amount of the soil in a vial and add water to it. You’ll also need to drop a reagent into the solution and wait for a certain period before checking the solution’s color against a chart provided by the manufacturer.Chemical tests are ideal for macro-nutrient testing of a soil, which aims to find the levels of Nitrogen, Phosphorus, and Potassium.

Digital Testers. With a digital tester, you get a system that relies on an electric charge to test soil, as opposed to chemical reactions above. They usually come with a probe that you’ll need to stick into the soil to get a reading.Although they are easy to use, digital soil testers need a battery to run on, and they’re often not as accurate as chemical testers. They’re, however, limited to tests for water and pH levels in the soil, an area in which they shine.

Professional Services. Another major approach to testing any soil is to use a professional service. All you need to do in this situation is to scoop the garden soil according to the lab’s instructions, and then send it in.The lab will then use its many lab equipments to test for the range of features that you requested. One downside of this method is that it’s costlier, but the upside is that it gives the best soil testing results.

2. Accuracy

Some soil test kits measure one or more factors, while other kits measure multiple nutrients, the important thing, however, is to get a soil test kit that accurately measures whatever it is that you want to measure.

The only way to do this is to check out the product and probably read some reviews to see how well it works. Many manufacturers will make claims about their kits, but only a proven kit is worth your money.

3. Ease of Use

Whether you are reading moisture levels, pH, temperature, or light with your soil test kit, the process has to be as easy to use as possible.

Many digital test kits just need you to stick their probe into the soil and read their output, while chemical kits need you to mix a certain amount of soil with a certain volume of water before comparing the resulting color with a chart.

For some folks though, the easiest way to test their garden soil is to simply scoop the soil and post it to a professional soil testing service, so it’s left for you to decide your desired level of convenience here.

4. Budget Considerations

Soil test kits come at different prices, ranging from less than $10 to hundreds of dollars. The price, will, of course, depend on the complexity and accuracy of the kit, with the cost of professional services also depending on the lab and on how much testing you want.

As you can imagine, you need to set your budget here and try to work within it by only spending on kits or testing that you can easily afford.

Conclusion

We’ve come to the end of this soil test kits review and you’ve seen all the great offers out there, including the simple 3-in-1 devices and the more elaborate laboratory services.

It’s left for you at this point to make your choice because it’s only you that knows what you need exactly and how much you are willing to spend.
