Texas Plant and Soil Lab

TP&S Lab, established in 1938 in the heart of the Rio Grand Valley, is a leading national testing lab for Soil, Plant, and Water analysis.

For over 75 years we have been perfecting the process of laboratory soil analysis, the Daubeny Extraction Method, utilizing Carbon Dioxide (CO2) to mimic the way plants naturally take in nutrients, and the Albrecht system of fertility balancing for optimum crop yields.

If you don't know what is in your soil or water, if you are at a loss to explain poor plant performance, if you have been told your soil or water or plants are beyond help, if you desire better yields and consistent harvest, or if you are unaware of the heavy metals in your soil, water and crops, we can help.

Our spectrum of services range from mail-in soil test kits for the 
at-home enthusiast, to resellable services for commercial providers such as nurseries, landscapers and greenskeepers, to government contracts, agri-corps and universities all over the world.
