The primary role of agriculturists are in leading agricultural projects and programs, usually in agribusiness planning or research for the benefit of farms, food, and agribusiness-related organizations.

[3] Agriculturists can also provide technical advice for farmers and farm workers such as in making crop calendars and workflows to optimize farm production, tracing agricultural market channels,[4] prescribing fertilizers and pesticides to avoid misuse,[5] and in aligning for organic accreditation[6] or the national agricultural quality standards.

Professional agriculturists may provide advice directly to farmers, vineyards, agricultural corporations, municipal and provincial governments, the fertilizer and seeds sector, consult on food processing, advise on range management, turf management and golf course operations, assess and provide remedial recommendations for brown lands (contaminated sites), watersheds, among many different areas of practice.

To qualify for entry level posts, the Agricultural Scientists Recruitment Board conducts competitive examinations pursuant to the Gajendragadkar Report of 1972.

On completing service for designated years and meeting set performance criteria, they are promoted to the next higher grades in a flexible complementation system known as Career Advancement Scheme (CAS).

The ARS encourages fresh infusion of talent at all senior levels through lateral entry in which incumbent scientists can participate in the open competition and move their career ahead in much shorter time than CAS.

Similar to other professions in the Philippines, malpractice and illegal practice of agriculture are grounds for suspension or revocation of certificates of registration and professional licenses.

The profession is exercised for the public interest in defense of the principles of Articles 9 and 32 of the Italian Constitution and of the Charter of Fundamental Rights of the European Union.

If accepted by their provincial institute, the applicant is known as an articling agrologist (AAg) or agrologist-in-training (AIT) and must complete a two-year educational and mentorship program before being considered for a professional designation.

An alternative certification called "registered technical agrologist" (RTag), or (PTag) is also available, requiring a two-year college or university education in the agricultural sciences instead of a four-year degree.

[26] CPAgs are required to complete at least 50 hours of continuing education through the American Society of Agronomy every two years in order to retain their certification.
