Soil testing is the only accurate way to determine lime and fertilizer needs for lawns, gardens, and pastures. It helps prevent over-application, saves money, and supports healthy plant growth.
What Soil Testing Provides
-
Soil pH (acidity or alkalinity)
-
Lime recommendations (if needed)
-
Nutrient recommendations based on what you are growing
Soil tests do not identify plant diseases, herbicide injury, drainage issues, or compaction.
When to Sample
Soil samples can be submitted any time of year, but it’s best to sample several months before planting so you have time to make recommended amendments. The North Carolina Department of Agriculture and Consumer Services (NCDA&CS) Soil Testing Lab is busiest in winter and early spring, so results may take longer during those seasons.
Submitting Soil Samples in Cabarrus County
Cabarrus County residents have two options for submitting soil samples:
-
Cabarrus Soil & Water Conservation District sends soil samples to the NCDA&CS lab in Raleigh on the first Thursday of each month.
-
You may also choose to mail samples yourself directly to the lab .
Soil sample boxes and submission forms are available for pickup, Monday-Friday from 8am - 5pm, and completed samples can be dropped off, at:
715 Cabarrus Ave W, Concord, NC
Cost of Soil Testing
Soil testing is free from April 1 through Thanksgiving for North Carolina residents, thanks to funding from a statewide fertilizer tax. A $4 per sample fee applies to samples submitted between Thanksgiving and March 31, which is considered peak season.
How to Collect a Soil Sample
Collect soil samples from areas where different plants are grown (for example: lawn, vegetable garden, flower beds, or pasture). Use a clean stainless steel trowel or soil probe and collect soil to a depth of about 6 inches.
Take several random subsamples from each area, mix them together in a clean container, and submit about 1½ cups of soil per sample. If certain areas are performing poorly, sample them separately to help identify potential nutrient or pH issues.
Receiving and Understanding Your Results
Soil test results are typically available within a few weeks and will be emailed to you from AGRONOMIC LIMS. Results are also posted online through the NCDA&CS system.
