A new program aimed at helping agricultural laboratories maintainhigh-quality performance has been established as a collaborativeproject between UC Davis and Utah State University. Analytical agricultural laboratories help farmers monitor a variety of potential soil pollutants ranging from fertilizers to animal waste to composted products. "No one wants to put out incorrect information, so this program was established to help the labs identify any problems they might have in specific analytical methods," says Robert Miller, Cooperative Extension soils specialist at UC Davis. Miller and colleagues at Utah State initiated the "Western States Agricultural Laboratory Exchange Program" in March. Results remain confidential, and Miller and colleagues offer to work with laboratories to help solve any analytical problems identified by the program. Currently 104 independent laboratories in 22 states and provinces as far east as Ohio have enrolled in the program, including 42 laboratories in California.
