The American Society of Agronomy (ASA) is a scientific and professional society of agronomists and scientists of related disciplines, principally in the United States but with a large number of non-U.S. members as well. It was founded in 1907 with the objective of 'the increase and dissemination of knowledge concerning soils, crops, and the conditions affecting them.' One of its founding members was Charles Piper, who would become its president in 1914. The first president was Mark A. Carlton and the first annual meeting was held in Washington, D.C., in 1908. Two daughter societies were subsequently formed, the Soil Science Society of America and the Crop Science Society of America. The ASA is headquartered in Madison, Wisconsin, and publishes a number of scientific journals. The ASA holds annual meetings attended by thousands of its members.
