We describe Pennsylvania's Commercial Manure Hauler and Broker Certification Program and discuss results of an industry survey. Survey knowledge questions were centered on state-mandated program competencies designed to minimize environmental losses of manure nutrients. Survey results demonstrated that participation in state-directed, Extension-led educational programming resulted in greater knowledge for those required to complete more rigorous certification education and for those exposed to more continuing education. Educational impact is expected to be far-reaching as survey respondents worked on an average of 38.5 farms annually. Extension's role is critical in this certification program that endeavors to improve water quality.
