The Grain Quality Incentives Act of 1990, passed as part of the 1990 Farm Bill, outlined a broad-based approach for addressing grain quality concerns and enhancing the competitiveness of U.S. grain exports. One issue addressed by the Act was the need to standardize commercial grain inspection equipment. As a result of this legislation, the Federal Grain Inspection Service was authorized to work with the National Institute of Standards and Technology and the National Conference on Weights and Measures to develop testing and standardization procedures for grain moisture meters used in commercial transactions. This overview summarizes activities and accomplishments for a national grain moisture meter program that was implemented in 1993. Results and discussion focus on efforts to improve uniformity of moisture content measurements for fifteen major grains included in an on-going moisture meter calibration program. Summary results are presented for multiple years of data for a variety of moisture meter technologies.
