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.
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 Gloria 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.
