Soil Testing

Properly conducted soil sampling and testing can be a cost-effective way to determine the types and amounts of fertilizer and lime needed to improve plant growth and yield.

There are four steps in a soil test:

  1.   obtain proper soil submittal form with sampling instructions,
  2.   obtain soil sample collection bag,
  3.    collect composite samples,
  4.   select proper test, complete submittal form, and mail form along with payment and sample to Soil, Water, and Forage Testing Laboratory in College Station, Texas.

Submittal form can be downloaded from

Forms and soil collection bags may also be obtained from your local AgriLife Extension Office.  Instructions on how to collect and ship the sample, along with the costs of testing and the mailing address are found on second page of the submittal form.


Homeowner’s should use form D-49B for home gardens, landscape, and soil.

Agricultural producers should submit form D-494.
