Diagnostic and soil labs
Turf disease and nematode diagnostic labs
If you are in any doubt about the identity or cause of a turf problem, we highly recommend the use of a qualified turf diagnostician. Fortunately, there are several labs that provide this service. Check with your local land grant university and/or county extension agent for information on regional diagnostic laboratories. If none are available, the following labs provide nationwide services (and in some cases can accept international samples) for reasonable fees. Labs should be contacted prior to sample shipment for specific preparation and shipping instructions.

Soil analytical laboratories
We work with and recommend Brookside Laboratories. Contact us if you’d like to do some testing.
PACE Turf’s soil, water, and leaf tissue guidelines are available here:
- We use the MLSN guidelines

There are many commercial laboratories such as Waypoint Analytical and Spectrum Analytic that can do routine soil nutrient analyses. We recommend using the guidelines above if you will interpret your own test results.
You may also be able to get testing done at a local or regional university soil lab.
