Sustainable Agriculture is a highly competitive, direct-admit graduate program, where students are admitted into the group of a major professor as well as into the SUSAG major. As such it is imperative that prospective students identify a potential professor BEFORE applying to the program. Applicants should review our faculty directory to identify faculty working in areas that align with their interests and goals. Once relevant faculty members have been identified, applicants should contact those faculty directly to inquire about open graduate positions and funding opportunities for their planned term of entry. Only applicants that contact faculty, apply for the program and are then nominated by a faculty member will be considered for admission to the program.

The SUSAG program does not allow for self-funding nor can we provide conditional admission. We also do not provide application fee waivers.
