How Much Does Soil Testing Cost? [2026 Data]

A soil test costs around $1,382, in most cases, and prices often fall between $652 and $2,112. Something like a simple garden soil test will cost between $10 and $200, testing for contamination can reach up to $400, while geotechnical testing can cost between $1,000 and $5,000.

Soil Testing Cost Breakdown

Generally, the materials for standard test kits cost $10 to $200. However, some tests, such as geotechnical testing, require heavy, expensive, specialized equipment, hence the higher price tags of these types of tests. 

Once you have your samples, labor depends on the amount of work involved for testing. For a chemist or lab technician to review your tests, you can expect to pay $100 to $200 per hour or $1,000 to $2,000 per day. While some test results are quick to process and review, others require a deeper, more time-consuming technical analysis. 

If you require an on-site technician, as in the case of a geotechnical soil test, expect to pay an additional $50 to $100 per hour or a day rate of $300 to $800. 

Cost to Test Soil by Test Type

There are many different types of soil testing, and which one you need depends on what you're testing for. Simple at-home tests tell you the basics about your soil, such as the current pH or what nutrients your soil is missing. However, more comprehensive tests may be required before construction projects or if any kind of contamination is suspected.

Note that contamination testing is sometimes just the first expense if you suspect you have an oil leak or some other chemical spill. You might need to budget much more for the cost of environmental cleanup, and you may need to pay fines for the contamination to the Environmental Protection Agency (EPA).

Garden Soil Testing

Garden soil testing costs $15 to $200. A basic at-home test that requires no lab processing comes in at the lower end of this range—but the results you get are pretty limited and often just tell you the soil pH and nitrogen, phosphorus, and potassium levels. More complete tests that require lab processing sit at the upper end of this range but include more detailed information about your soil's composition and nutrient profile.

Lawn Soil Testing

Lawn soil testing ranges from $20 to $100. You can expect to pay closer to the $20 mark if you plan to do it yourself. If you're planning to seed a new area or have issues with an existing lawn with persistent dead patches, poor health, or just inadequate growth and performance, you should consider doing a lawn or turf test. 

These kits contain everything you need to sample your soil at home. Some have at-home processing, so you get basic answers fast, while others provide more detailed results, requiring that you send them away to a lab for processing. 

Testing the soil in your lawn tells you what your soil is lacking or has too much of and lets you strategically plan and add the right amendments to remedy the issues and grow a healthy lawn.

Sulfur and Boron Testing

Sulfur and boron testing costs $25 to $100 and is a smart test to order if your plants exhibit smaller vegetation, stunted growth habits, and reduced fruit yield. Sulfur and boron are important but often overlooked nutrients; they have a significant impact on lawn and garden health. So, if you already have problems or are planning a new growing space, this is a test worth using.

Soil Texture

Soil texture testing costs $35 to $75 and is also known as ribbon testing. It's an easy and inexpensive test that tells you the basic composition of your soil.

Once you know the basic makeup of your soil, you can find the plants that thrive in those conditions or add the right amendments to rectify issues. Problems you can correct include compaction and lack of drainage in heavy clay or the lack of moisture retention in excessively sandy soil.

Specific Contaminant Soil Testing

Individual tests to look for the presence of single specific contaminants cost $30 to $50, on average. You'd use a test of this type if you suspect a specific contaminant may be in your soil, as these tests are less expensive than broad-spectrum testing kits. For example, if you suspect lead in the soil, it costs less to purchase a test for lead than a broader heavy metal contamination test kit. 

Homeowners often use these types of tests when they suspect or want to eliminate a single contaminant, such as lead, E. coli, petroleum, or solvents.

Gravity of Soil Testing

Gravity soil testing costs $50 to $80 and tells you how much water your soil can hold. It's an important test if you plan to grow a fruit or vegetable garden, as the water content of your soil, its ability to retain moisture, and to what degree will all determine the success or failure of your growing space. 

Similarly, this test is most common during the planning stages of a construction project. Experts who do soil testing use this to determine if the soil retains too much water or drains too rapidly. In either case, soil expansion and contraction from changes in moisture can cause instability under and around your foundation, leading to damage. Once the contractor has this information, they can determine what amendments they’ll need to make to prepare the ground for construction.

Similar to gravity testing, a soil perc test or percolation tests the drainage of the soil, specifically around septic systems. Whether you need a traditional soil test or a perc test will depend on why you’re testing how much water your soil can hold.

Fertility of Soil

Soil fertility testing costs $50 to $300 and is a more comprehensive study of the soil's composition than the standard garden test kits. With this kind of test, you get a full nutrient profile of your soil, showing how fertile it is, what's lacking, and what you can do about it. This lets you replenish missing nutrients and plan to grow plants that will thrive in your specific soil.

Heavy Metal Testing

Heavy metal soil tests cost $70 to $200 and, as the name implies, test for the presence of potentially harmful heavy metals. This is a broad-spectrum test and looks for multiple heavy metal contaminants, including, but not limited to the following:

• Arsenic

• Cadmium

• Chromium

• Copper

• Lead

• Nickel

• Selenium

If the test identifies any of these harmful substances, you can then take steps to rectify the issue. Heavy metal contamination is a common problem with soil in older residential areas or residential areas that were formerly commercial areas. 

Basic Soil Profile Testing

Basic soil profile testing costs $270 to $300 and provides a detailed breakdown of the composition of the soil, but it goes beyond the standard top few inches sampled in garden and turf testing. 

With a soil profile of this type, the test examines the soil's makeup from the surface down to the bedrock, giving you a more complete picture. However, it still doesn't provide you with any information about contaminants. 

Advanced Soil Testing

Advanced soil profiling costs $500 to $570 and provides a complete picture of your soil, including its structure, composition, nutrient profile, and levels of a range of potentially dangerous contaminants, including heavy metals. 

Oil Tank Soil Testing

Oil tank soil testing costs $500 to $550 and is essential if you have or previously had an oil tank buried on your property. This soil test identifies whether oil has been leaking from the tank and spreading through the surrounding soil, which would be a serious health and environmental hazard.

This test is costly because soil has to be taken from around the whole perimeter of the tank and sent to a lab for processing. If your test reveals that there is an oil leak, you’ll also have to pay fines to the EPA, and you’ll need to pay for an environmental cleanup, which can cost thousands of dollars.

Geotechnical Testing

Geotechnical soil testing costs $1,000 to $5,000 and determines the suitability of the land for the construction of a home. This type of comprehensive test involves multiple individual tests that look for safety, suitability, stability, and proper drainage. It can also help to determine what type of foundation works best, how much drainage is required, where to put drainage, what fill dirt to use, and where to direct groundwater.

“Geotechnical testing” is really a catch-all term for a handful of different specific tests you might need that collectively make up a geotechnical test. You may only need a few of the following tests before construction.

Cost of Common Soil Testing Add-Ons

Soil testing is often the first step in a larger project, so you may want to consider the following add-ons and budget for your next steps at the same time.

• Garden bed installation cost: $4 to $12 per square foot

• General landscaping cost: $1,200 to $6,000

• Septic system installation cost: $3,600 to $12,400

• French drain installation cost: $500 to $18,000

• Foundation repair cost: $2,200 to $7,900

• Cost to install a retaining wall: $3,200 to $9,200

• Cost to build a house: $139,000 to $526,000

• Cost to seed a lawn: $440 to $1,750

DIY Soil Test vs. Hiring a Pro

You can perform a basic soil test yourself for as little as $15. However, at this price point, the information that you'll get will be fairly basic, like the nutrients present or missing in your soil. But, in some instances, such as if you're just checking the pH or nutrients to see if they are suitable for growing blueberries, that basic information is all you need. 

However, when a more detailed report is necessary, you cannot do the test yourself unless you have access to a processing lab and the skills to complete the scientific analysis. You can, however, often save money by collecting the samples yourself so you don't have to pay for an on-site technician. 

For specialized tests, such as geotechnical soil testing, you really can't do any part of it yourself, so you’ll need to hire a soil tester near you. That's because the equipment needed to gather all the appropriate samples is cost-prohibitive to the average homeowner and requires a high degree of specialized knowledge.
