We believe that our laboratory offers the best price value per sample available. We utilize the top technologies available in our analysis processes, our turn around time and customer service is as good and any competitor lab in the business, and the variety of testing methods and recommendations that we offer is second to none. Our lab is owned by agronomists who utilize the data that is produced each and every day, so we have designed our lab to meet the those needs. Inexpensive, high quality, rapid testing with a variety of methods and recommendations!! We believe we offer the best value in the soil testing market to date!
The two most common extraction methods that our lab uses are Mehlich 1 and Mehlich 3. The Mehlich 1 uses a weaker acid and is the most common soil extraction method used in the Southeast, where soils are lighter and more acidic. The Mehlich 3 extractant, also termed "the universal extractant", is made up of stronger acids and is more common in the Mid South and Midwest where soil are heavier with higher clay content and typically not as acidic. Other extraction methods include Lancaster, Bray 1, Olsen, and Morgan, however we currently do not offer these extractions methods at our Georgia location. Our partner lab in Mississippi does offer the Lancaster extraction method.
Our laboratory uses Inductively Coupled Plasma Spectrophotometry (ICP-OES) for the nutrient analysis of the following: Phosphorus (P), Potassium (K), Magnesium (Mg), Calcium (Ca), Sulfur (S), Boron (B), Zinc (Zn), Iron (Fe), Copper (Cu), Molybdenum (Mo), and Aluminum, (Al), as well as others upon request. These instruments utilize the most advanced technology currently available for nutrient analysis for soils and plants and are the most commonly used instrument found in agricultural testing laboratories worldwide, for nutrient testing. We maintain 6 of these instruments equipped with high speed auto samplers that utilize the FAST system which allows for samples to be analyzed rapidly (see pic).
For Nitrogen Analysis we utilize the Leco 928 series analyzer which is the most advanced Nitrogen analyzer on the market. We also utilize multiple Elementar Nitrogen Analyzers.
Our lab uses robotics for pH analysis as well as having manual stations. We utilize both combustion and/or muffle furnace methods (LOI) for Organic Matter determinations.
Our laboratory typically has sample results available within 48 hours or two business days from the receipt of the sample at our lab. However, there are times when sample volume is extremely high or when we have scheduled maintenance on equipment that turn around times may be 72 hours or longer. It is RARE that we exceed more than 5 business days on soil sample turnaround time. If you have not received your samples within this time frame then you should call the lab as something may wrong. PLEASE REMEMBER Saturday and Sunday are not business days...although our lab typically remains open on Saturdays during busy times.
We provide free shipping labels via UPS. We also provide sampling supplies (bags), and boxes. To qualify for free shipping each box must contain a minimum of 15 soil samples. If a box contains less than 15 samples then shipping fees will be incurred by the client.
We offer our clients access to an online web portal in which reports can be viewed, turnaround time is shown, crops can be changed, reports combined, and a variety of other options. Please contact the office to set up your username and password. Follow the link on this site to www.seagrilab.com for portal access.
All samples are dried overnight in forced air ovens, ground to pass a 10 mesh screen. Samples remain in original sample bags throughout the process so that sample identification on the bag remains intact as well as no transfer errors occur. Samples are scooped and the Mehlich 1 extractant is added and shaken for 5 minutes. Samples are filtered into test tubes and then analyzed via ICP instrumentation.

All samples processed the same as Mehlich 1 except using the Mehlich 3 extract. Sulfur comes standard with Mehlich 3 because the extract contains no sulfur and does not require additional methods to determine.

Standard Turn around time is 48 to 72 hours for soils. There are times when the lab is exceptionally busy and turn around may exceed 72 hours, however this is not typical. Occasionally, growers need samples results back ASAP, and for those times we offer 24 hour and 48 hour priority services. These Priority Services incur small per sample fees but allow samples to be bumped ahead of those that do not have pressing needs for results.
This option moves your samples ahead in the process with the goal of next day turn around from the time it is received at the lab and assurance that it will be processed within 48 hours.
The next day guarantee will assure your sample results will be ready the the next business day from when the sample was received at the lab by 5pm. This assurance adds $10 to the sample cost. If for some reason the samples are not finished then no additional fees apply.
We provide free shipping for UPS ground packages that have a minimum of 15 samples per box. We also provide boxes and bags for our clients. Please contact the lab or use the materials request for at this website to order supplies.
Shipping is free as long as clients send a minimum of 15 samples per box. Packages that contain less than 15 samples will be charged $1 per sample for the difference between samples sent and 15. Example a box with 10 samples would incur a $5 shipping charge to the client.
