The Pullman Plant Materials Center (PMC) is a 320 acre farm unit located one mile east of Pullman, Washington. The PMC lies in the heart of the Palouse Hills region which is internationally recognized for outstanding wheat yields and sadly, some of the highest soil erosion rates in North America. Numerous conservation practices including terraces, permanent vegetative cover, and shelterbelts have been installed and are still maintained at the PMC in an effort to demonstrate the utility of these practices.
The three state area served by the Pullman PMC includes eastern Washington, eastern Oregon (east of the Cascade Mountain range), and northern Idaho. Testing has been performed at a number of locations but currently is concentrated at Pullman and the WSU Dryland Research Unit, Lind, WA.
Pullman is also the home of Washington State University. The main offices of the PMC are located on campus within the James H. Hulbert Agricultural Sciences Building (Hulbert Hall).
