TURF SOIL AND
SOIL HEALTH TESTING
Gain the insights needed to optimize turf health.
Soil and soil health testing provides a nutrient roadmap to make the best turf management decisions to optimize turf health and longevity.
Beyond monitoring soil conditions and gauging the effectiveness of fertilizer applications, we provide the information you need to implement an effective, data-driven action plan.

AgSource can provide a variety of reporting options customized to your specific needs, including transfer of data via API.
Popular report options include:
A good sample is the key to an accurate analysis. Consistency is the important to obtaining the most accurate soil test results for a soil fertility program. Follow our basic sampling reminders for best results.
AgSource Laboratories Soil Sampling Reminders:
- Determine sample locations. Record locations for future reference – this is particularly important for fairways. Do not mix sub-samples from different greens or fairways, always sample each separately.
- Take samples. Keep sampling depth consistent – sample greens to a depth of three inches, other turf samples can be to a depth of three to four inches. Take multiple sub-samples – about 10-15 sub-samples are needed for a representative nutrient analysis. For consistency, include a layer of thatch in your sample. Avoid fertilizer residue contamination – wait a minimum of two weeks after an application before collecting soil samples. Avoid “unusual” areas that are not representative of the larger area you are sampling.
- Identify samples. Clearly mark the samples and identify each sample bag on the submission form. Indicate type of turf being tested on the submission form and package choice.

Turf Plant Tissue Testing
Tissue testing provides a snapshot of your turf’s nutrient status at the time of sample collection. This can be helpful if you’re wanting to understand and track the nutrient status throughout the season, or are trying to pinpoint a specific problem.
