What updates will I receive on my sample status?
Generally, the first update you will receive is the emailing of your sample analyses report(s).
What is the Sample ID and where do I get this?
Sample ID is the unique term or name you give an individual sample, thus allowing you to know which sample is which when the sample report(s) are returned to you. For example, “Front Yard” or “Back Yard 2022”.
Can I dropoff the sample to the laboratory?
The laboratory lobby is open Monday-Friday, 8 a.m.-5 p.m. on days that the Texas A&M University campus is open. This includes closure due to weather or early dismissals.
Can I use the same soil sample for my garden, lawn and trees?
Unlikely if the landscape is already established, as differences in amendments, fertilization and tillage that have been imposed on the soils/areas often result in differences in soil nutrients and plant growing conditions.
Do I need to collect different soil samples from the front and back yard?
It all depends. Commonly, landscapers and homeowner treat the front yard differently than the backyard, sometimes from the very beginning. These differences in fertilization, soil placement and etc. can result in dramatic differences in soil analyses and subsequent lawn growth.
My soil is contaminated. Can you still conduct analyses?
The laboratory will refuse to conduct analysis on non-conforming samples. Non-conforming samples include samples with odors of hydrocarbons, pesticides, significant foreign substances includes plastics, glass and other materials that could be hazardous to staff and facility.
What is the D-494 form?
This is the old term used for our general Soil Submittal form. The printing on some of the existing soil sample bags still has this terminology, as a soil submittal form or online information submittal is required with each soil sample submitted to the laboratory.
How often should I soil sample?
This differs depending on circumstances. Annually if your prior soil analysis report indicated any needs for non-nitrogen additions, limestone additions and elevated salinity. Additionally, high value crops and forage systems where hay is removed, annual soil testing is strongly recommended. Soil sampling following drought is also recommended, as residual nitrogen might be present and crediting this nitrogen is both economically and environmentally prudent. Under other circumstances, every other year or every third year maybe justifiable.
Where do I get your soil sample bags?
The laboratory does not inventory these bags; however, many Texas A&M AgriLife Extension County offices do order and stock the bags. The bags are not required, while1-quart freezer zip lock type of bags are perfectly acceptable.
How much soil do I need to send?
Most testing suites require about 2 full cups of plant and rock free soil. A full pint of soil is recommended to avoid having to send additional soil. Testing suites including soil texture and detailed salinity require at least a pint of soil.
What is the AG-257?
This is a Texas A&M AgriLife Administrative form (Banking and Receivables) that is required for all billing/invoicing of customers in the Texas A&M University System Ipayments accounts receivable system. This form must be on file for clientele requesting to be invoiced for services.
