Agriculture
Program Overview
Established in 2007 as a joint effort between CTS and Dr. Robert O. Miller, the CTS Agricultural Laboratory Proficiency (ALP) Program combines our lengthy and extensive experience in operating interlaboratory programs with Dr. Miller's noted expertise in agricultural testing, offering a wide array of analyses on agronomic soils, carbon sequestration soils, botanicals, and water.
Technical Director Dr. Miller prepares test samples, assists with interpreting the collected data, and provides the Director's Analysis and Comments report. CTS prepares and distributes the Summary Report and Individual Performance Analysis Reports, which contain results for all properties and samples for which a laboratory submitted data during a testing cycle.
