Welcome to TP&S 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.

In conjunction with the most accurate of laboratory results in the industry and the closest to Nature of methods, TPSL specializes in soil fertility and plant nutrition. We have trained and certified professionals who have interpreted tens of thousands of soil test over decades of years.

Our proprietary Ask the Plant® program allows you to dynamically adjust your fertilization program to accommodate your crop's ever-changing nutritional requirements throughout the growing season resulting in higher crop yields, reduced water use, eliminating fertilizer waste and ensuring a healthy, safe product.

We are proficient in all chemical, organic, biological and physical aspects of agricultural science.

On our site you can review our services for soil, plant, and water testing, analysis and recommendations. We are also able to accommodate special requirements testing not see here.

about your needs.
