If you have a beautiful garden, a vegetable patch or fruit trees, and you need to fertilize regularly, soil test kits are a valuable tool that can help you do the job correctly.

Soil is the foundation of your garden and it is very important that it’s in the right pH and nutrient levels for the plants that you’re growing. Using soil test kits to create nutrient solutions can help your garden thrive.

Soil test kits can be used for a variety of areas including:

  • garden soil
  • lawn soil
  • seed starting mix
  • hydroponic soils
  • amendments
  • water

Because all plants need different nutrients, soil test kits cannot test for everything, but they are very practical, easy to use, and comprehensive and will give you the information you need to figure out what nutrients you need to add to your soil.

Frequently Asked Questions (FAQ)

What is the most accurate soil pH tester?

The most popular and accurate indi garden is the Taylor Soil Meter. One major pro is that the pH of the soil is tested instantly. The meter also displays a seven-point slider. This is the best pH tester for the money and also the best one to own in your gardening toolbox.

Are soil pH testers accurate?

Asoil pH tester measures the content of potassium or hydrogen ions in soil. The pH range is from 0 to 14; 7.0 is the neutral end. Most plants are adapted to grow best in a pH range of 6.5 to 7.0, with 7.0 being ideal. A pH greater than 7 indicates alkaline soil, while a pH less than 7 indicates acidic soil.

Depending on the plant cultivated, a high or low pH level in the soil may cause harm or inhibit plant growth.

Can I test my soil myself?

Yes, because one of the ways to get great soil is by simply making sure that everything is balanced in the soil you already have. A soil test can help you get the nutrients your soil lacks and skip the guesswork and adding of excess nutrients that may cause more harm than good.

There are kits that walk you through the process as you take samples and then mail them in to a lab. Today with services like Amazon, it is very easy to get started with a home soil testing kit.

What chemicals are used in soil testing kits?

Majority of the soil test kits available in the market use most of these chemicals in testing the soil.


If you haven’t had your soil tested before, then it’s time. Many of the best gardeners I know test their soil regularly and are always on the lookout for natural solutions. This way, they know the pH level of their soil and can take measures to keep it healthy and add amendments where needed. This is much easier than waiting until you see problems before you decide to test and correct. I’m not trying to scare you with warnings of doom and gloom, but soil test problems rather than having annual problems.
