The Oklahoma CCA program is a voluntary certification program for individuals who provide advice to growers on crop management and inputs. Certified Crop Advisers meet the standards set by the American Society of Agronomy including passing rigorous examinations, maintaining continuing education and subscribing to a code of ethics.

The Oklahoma CCA demonstrates a commitment to professionalism as well as the knowledge and skills necessary to help growers produce economical and environmentally sound crops.
