Best Soil Testing Kit On The Market: Frequently Asked Questions (FAQs)

Are home soil test kits accurate?

mini soil test

Home soil test kits are generally accurate when testing the soil’s pH levels and nutrient deficiencies. That being said, you must use good quality test devices.

You are bound to get uneven, false, and unreliable results with cheap testing devices. No one can guarantee the accuracy of home soil test devices, but testing with such devices is better than not testing at all.

These tests are quick and economical compared to test results from analytical laboratories. If you are a home gardener or wish to know the soil type, we recommend using a home soil kit.

On the other hand, if you plan on growing massive crops and farming for food, you must have a professional laboratory test. These tests give 100 percent accurate results, so your intense labor and time won’t go in vain. Home soil test kits are usually manufactured for hobby gardeners and plant lovers.

These test kits are good to have around the house for a quick update. People living in remote areas use home soil test kits religiously. These soil analysis kits lack precise decimal units; they generally classify the results into broad categories like high, medium, or low.

American society for horticultural science has a research journal that states Rapitest kits are 92 percent accurate. Therefore, using a home soil test is not a bad option if you are a budding gardener. It will surely give the correct result provided you use a trusted brand, like the ones mentioned in this buyer’s guide.

Do soil testers work?

soil tester in pot

Yes, soil testers work to provide necessary information related to your soil. Soil testers work on the basic principle of finding a lacking mineral or component. These testers are mini versions of complex laboratory machinery that we see in a professional laboratory.

The inaccuracy with the results makes people question these soil testers. As mentioned earlier, a good quality soil tester will always work and give you correct results. For getting the best accurate results with these soil testers, refer to our next question below.

How to use a soil test kit for best results?

Using a soil test kit isn’t difficult or complicated if you follow the instructional manual, but you can get inaccurate results if you make mistakes.

We will go through 3 types of soil test kits and few best result tips for each product to help you with that.

Probe meter

  • You need to push the switch to the desired test setting like pH, light, and moisture.
  • Insert the probe into the soil about 4-5 inches, keep the dial steady and check the results after 10 minutes. Wipe the probe before storing it.

For best results

  • Avoid using the probe meter continuously without giving it some time to rest.
  • Try to note down the result after 10 minutes and before 12 minutes.
  • Water the soil before testing the product as dry soil won’t give the best results.

pH test

  • Collect the soil from your garden’s major spots and mix the final heap of soil.
  • Mix the soil with water and form a mixture.
  • Dip the test and hold it for 3 seconds. Measure the test strip by referring to the color chart.

For best results

  • Collect the soil from all levels of the soil bed.
  • After mixing the soil with water, let the mixture sit for 20 minutes. After 20 minutes, stir the mixture and let it sit for another 10 seconds, then dip the test strip.
  • Avoid using brass, bronze, or galvanized utensils for mixing purposes. Try to use clean plastic or glass bowls for the process.


  • Collect the soil sample and let it sit overnight with the water solution.
  • With the help of a tiny dropper, fill the vial and add the chemical capsule. Let the tube sit for another 10 minutes, then put the vial in the testing machine. Press the button of your desired test and get instant results.

For best results:

  • Keep the soil and water mixture for 24 hours.
  • Avoid touching the chemical with bare fingers.
  • Press the accurate button for the right color-coded bottle.
  • Avoid using tap water to mix the soil as it will add more minerals. You can add distilled or rainwater.

How do you test a field of soil?

soil testing results

You have to take accurate soil samples if you wish to test a field or soil accurately. The result will get accurate if you carry out the soil sampling the right way.

Divide your field into different areas

Sample only the areas with a similar crop, cropping history, texture, and fertility history. If the soil is exceptionally different in your field, you can sample that patch in another separate batch. Limit one sample to 20 acres for flat land and up to 5 acres for a hilly region.

Sample each area

Collect 15-30 subsamples from each area in a zig-zag pattern. Avoid sampling the site’s surface soil as it will have unwanted minerals that can give you inaccurate results.

Try sampling to a depth of 7 to 8 inches for cultivated crops and 3 to 4 inches for sod fields and pasture. Try to avoid sampling back furrows, old fence rows, fertilizer or lime spill areas, low spots, and small saline areas. Make sure to sample at least 300 to 350 feet away from crushed limestone or gravel roads as their dust changes the soil’s pH.

Mixing the subsamples

Mix the soil subsamples thoroughly in a clean plastic container. Dry the soil for 24 hours if the test requires a wet soil mixture. Do not microwave the soil unless you plan on doing a nitrate test.

Testing the field

Your main work is done; you can send the samples to the laboratory or carry out home soil tests. If you wish to perform a home soil test, we recommend reading the manufacturer’s manual for a detailed report.


We encourage new gardeners to overcome their fear of dead plants.

You can plant several trees and have a luscious green garden or yard by learning about your soil. Keep checking the soil nutrient level, and enjoy the gardening process.
