Rankin County’s Extension office can help with a soil-test question, but it is not the mailing destination printed in MSU’s current submission instructions. Those instructions direct samples to Southern Soil & Plant Lab, LLC., 117 Haley Barbour Parkway, Yazoo City, MS 39194. Check the current order instructions before mailing a bag to an address in an older handout. MSU submission route
Local help and laboratory delivery are different stops
The Rankin office is at 601 Marquette Road, Brandon, with telephone 601-825-1462. Ask whether local staff can assist with your planned test and whether any local drop-off arrangement is available; this review did not confirm one. Rankin directory
For the MSU-linked mailing route, use the Yazoo City destination above. MSU’s current testing page lists 662-325-3226 for submission questions and 662-746-8105 for the named laboratory. These contacts serve different purposes from the county office. Testing services and contacts
Match the order to the bag—and the result to the area
MSU instructs the sender to put both the order number and sample name on the soil-sample bag. Start from its official submission page to obtain the order route. Bag-label instructions
Before sealing a shipment, make this short cross-check:
| Match | Why it matters |
|---|---|
| Order number on the order and bag | Connects the physical sample to the submitted request |
| Sample name on the order and bag | Distinguishes one sampled area from another |
| Your sample name and intended planting in your own notes | Lets you connect the eventual report to the correct bed or lawn area |
The first two identifiers are MSU’s instructions. The third is LSL’s record-keeping suggestion, not an additional laboratory form requirement. Follow the current collection directions rather than treating this identity check as a sampling protocol.
Select the question the analysis can answer
MSU describes this route as nutrient testing for lime and fertilizer recommendations. Its overview says recommendations depend on the selected crop codes and lists the standard analysis and optional services separately. Confirm the intended planting, selected analysis and current charge before paying. Test scope
A fertility report is not a drainage design, foundation assessment or contamination clearance. Nor should an old publication’s price or turnaround be treated as a current order quote.
LSL compared the current county directory, testing overview and submission instructions on September 13, 2026. This revision adds the current shipping destination and bag-label instructions missing from the earlier guide. The laboratory is named solely to identify that destination; no commercial placement, sample submission, analysis or service endorsement occurred.
