The OSU Crop and Soil Science Central Analytical Laboratory operates as a fee for service laboratory. We accept soil, plant, water, and soil amendment samples from OSU faculty, staff, students, and extension faculty, as well as gardeners, field reps, and commercial producers.


Update 9/21/18 Effective immediately, Shannon Andrews is no longer the manager of the OSU Central Analytical Laboratory. Responsibilities for laboratory work and business management are being transitioned to Gloria Ambrowiak and responsibilities for consultation and soil health projects are being transferred to Markus Kleber. If you have any questions, please feel free to call or email Gloria at 541-737-2187


Update 8/7/18: Our Shimadzu TOC and TN is not in working order. Therefore, right now, we can not analyze dissolved carbon or nitrogen and can not quantify microbial biomass. Please contact for further information. 

We are focused on research projects and are often significantly slower than commercial laboratories. Please call prior to submission if you are on a schedule. 
CAL is a central piece of the OSU soils educational program as well as a fully functional soil and plant analysis laboratory. As such we offer discounted rates for student preparation of samples as well as analytical training. Researchers, please contact Shannon to discuss use of our facility. 

We are actively pursuing collaboration with OSU faculty, staff, extension, and experiment station scientists as well as the NRCS, SWCDs, and ODA. If you have a project related to soils, but are not sure how to sample or what to analyze for, contact us and we can help you with your plan or develop a method.
