The vitality of your grass and other plants is closely tied to the well-being of your soil. Prioritizing soil health ensures superior grass quality from the ground up. While regular lawn fertilization is a good practice to provide essential nutrients, determining the precise nutrient needs of your lawn can be challenging.
For instance, despite consistent nitrogen application, you may not observe improvements in the appearance or quality of your grass. Uneven growth patterns might also be evident in different areas of your lawn, without a clear understanding of the underlying reasons.
Before investing time and money in potential solutions, a prudent approach is to conduct a soil analysis on your property. This analysis reveals the specific nutrients your lawn requires for optimal growth.
What is a soil test? It's a tool that assesses the macro and micronutrients present in your soil, indicating the necessary adjustments for your lawn and garden to attain an ideal pH level. Recommendations for soil enhancement, typically involving fertilizers or amendments, are often provided based on the test results.
Soil tests vary in forms and procedures, but generally involve collecting a soil sample from your lawn and submitting it for analysis. The method of submission—whether by mail or through a local cooperative extension office—depends on the chosen company or turfgrass expert.
Why should you use a soil test? It's a cost-effective means to identify your soil's requirements for optimal performance. As the pH levels of soil can be influenced by frequent fertilizer and chemical applications, a soil test offers insights into the specific nutrients your lawn needs, preventing unnecessary expenses on redundant fertilizers. Additionally, it helps avoid environmental harm caused by excess fertilizers washing into natural water bodies.
Conducting a soil test empowers you to make informed decisions about the fertilizers and nutrients your soil truly needs, contributing to a healthier environment for your lawn and garden.
To collect and submit a soil analysis:
- Use plastic probes or baggies to collect several soil samples from different locations in your yard.
- Walk in a zigzag pattern, collecting samples from 10–15 locations.
- Remove any plant material, mulch, or organisms from the samples and combine them in a plastic bucket.
- Allow the soil to dry before collecting about 1 pint for submission to a turfgrass expert.

The timing of soil testing varies based on grass type and location. Warm-season grasses, such as zoysia, should be tested in spring, while cool-season grasses like Kentucky bluegrass are best tested in late summer or early fall.
How often should you test your soil? Most experts recommend testing every 1–3 years, or more frequently if issues arise. Submitting soil samples is an invaluable practice for maintaining the health of your lawn and garden.
Consider factors like pH levels, nutrient deficiencies, and micronutrient importance when interpreting soil analysis results. Overreliance on macronutrients without addressing micronutrient needs can impact your lawn's health. Carbon, often overlooked, is a vital component for soil balance and plant health.
For soil improvement following a soil analysis, some tests come with product suggestions. If not, understanding fertilizer labels is crucial for selecting the right product for your soil.
In summary, conducting a soil analysis is a proactive step towards ensuring the well-being of your lawn and garden. It provides valuable insights into nutrient needs, prevents unnecessary expenses, and contributes to a healthier environment.
