"Welcome to Texas Plant and Soil Lab
Texas Plant and Soil 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 70 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."
