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

Each organization is autonomous with its own bylaws and governing boards of directors. The Agronomic Science Foundation supports ASA, CSSA, and SSSA activities, programs, and projects.

Agronomy looks at agriculture from an integrated, holistic perspective. Agronomists are specialists in crop and soil science, as well as ecology. Some things they look at are:

The properties of the soil;
How the soil interacts with the growing crop;
What nutrients (fertilizers) the crop needs;
When and how to apply these nutrients;
The ways that crops grow and develop;
How climate and other environmental factors affect the crop at all stages;
How best to control weeds, insects, fungi, and other crop pests; and,
How to grow crops effectively and profitably while conserving and protecting the environment.

Agronomic crops can also be grouped by the type of crop grown. Many agronomists specialize in one or more types of crops. According to the USDA the major crops grown in the US are:

Soybeans
Corn
Wheat
Hay
Cotton
Grain sorghum
Rice
Oats
Barley
