Testing Material Costs

Material costs range from $10 to $150 depending on the test. For most lab samples, you can use plastic bags or order special bags from the lab of your choice.

DIY Soil Testing vs. Hiring a Pro

For instant results for your garden, a DIY home test kit might be all you need. Or, you can start with a DIY solution. First, use a home kit to screen. Then, move to a lab for a detailed analysis if it comes back positive for heavy metals or other impurities. You can also hire a local soil testing service for gardens and agricultural needs.


Why is it important to test soil?

It’s important to test soil during new construction to make sure your home won’t shift after it’s built. Toxin screening makes sure the soil and groundwater is clean. For gardens and agriculture, it’s important to know soil composition for healthy plants and to improve crop yields.

What type of soil test do I need?

The main soil tests you’ll need can be broken down into two categories:

  • Agriculture and garden – determines the suitability for growing crops.
  • Geotechnical testing costs $1,000-$5,000 – determines the suitability for building structures.
