The American Society of Agronomy (ASA) is a progressive international scientific and professional society that empowers scientists, educators, and practitioners in developing, disseminating, and applying agronomic solutions to feed and sustain the world. Based in Madison, WI, ASA is the professional home for 8,000+ members and 14,000+ certified professionals (Certified Crop Advisers) dedicated to advancing the field of agronomy. ASA provides information about agronomy in relation to agronomic production, biometry and statistical computing, climatology and modeling, education and extension, environmental quality, global agronomy, and land management and conservation.

Founded in 1907, ASA supports its members and certified professionals by providing peer-reviewed research publications through the Digital Library, educational programs, certifications, meetings, and science policy initiatives via a Washington, DC office. A common thread across the programs and services of ASA is the dissemination and transfer of scientific knowledge to advance the profession.
