Can I Hire a Lawn Care Professional for Soil Testing?

Lawn care professionals sometimes offer soil testing as a standalone or add-on service. While they have less formal engineering training than a soil engineer, they can be a practical choice, especially if you already use their mowing or landscaping services. Many send samples to a professional lab for comprehensive analysis, often including micronutrient levels. Verify their tools and experience before hiring to ensure you get quality results and clear recommendations. If you want a more thorough analysis or need help interpreting results, you might want to consider a soil testing pro near you to ensure the job is done accurately and meets your local requirements.

How Do Soil Engineers Complete Soil Tests?

Soil engineers follow a structured process to deliver dependable results.

1. Use a soil probe or sharp spade to collect multiple samples from selected locations

2. Take the same amount of soil from each spot for consistency

3. Remove twigs, rocks, roots, and debris that could skew results

4. Send prepared samples to a certified soil testing lab

5. Review lab results with you, recommend fertilizers, and explain how to use findings to meet your goals

How Much Does Soil Testing Cost?

Soil testing costs depend on whether you DIY or hire a professional and on the type of test. DIY soil testing costs about 15 dollars and provides basic information. Hiring a soil engineer for advanced analysis generally costs 100 to 200 dollars per hour or 1,000 to 2,000 dollars per day. The test type you choose affects both price and detail level. More comprehensive services cost more but deliver deeper insights and clearer recommendations.
