How it works
- 01
Get a form and sample the way your lab says to
Pick up a form at a county office or download it from Clemson Agricultural Service Laboratory. Where you pull cores and how you mix them decides whether the report means anything, so follow the lab's instructions exactly.
- 02
Send it in
Many county offices accept the sample and route it to the state lab; otherwise mail it in with the form.
- 03
Turn the report into a plan
When results come back, the numbers only matter if they change what you put down. Enter them in the app and it builds the plan.
THE APP · SOIL REPORT ANALYZER
Got your South Carolina report back? Analyze it.
Enter your report values in the Lawn Dominator app and pick your lab, and it handles the messy part: units and extraction methods differ by lab, so your numbers get compared against turf targets that match how your lab measured them. Then it helps build the fertilizer plan for your grass type and checks timing against your live soil temperature.
