Agronomy

Undergraduate Study

The Department of Agronomy has a curriculum noted for its scientific rigor and breadth in crop science, soil science, agricultural meteorology, and plant breeding. It prepares students for science-based professional positions, graduate study, or research careers across the spectrum of Agronomy.

The curriculum provides both flexibility and direction for students by offering four in-depth options: crop management and business, agroecology, soil and environmental quality and plant breeding and biotechnology. A minimum of 15 credits of Agronomy courses must be earned at Iowa State for students transferring from other institutions. The program also has many opportunities for undergraduate students to be involved in cutting edge research and international agriculture.

Graduates have the theoretical and practical knowledge needed for efficient and sustainable production of food, feed, fuel, and fiber. Graduates are skilled in communications, critical thinking, problem solving, and working effectively with others. They understand the ethical, cultural, and environmental dimensions of issues facing professionals in agriculture and natural resources.

An Agronomy major prepares students for employment in agricultural business and industry, agricultural service organizations, crop production and soil management, environmental and natural resource management, and farm management. Graduates pursue careers in the seed, fertilizer, and agricultural chemical industries as field Agronomists, crop and soil management specialists, research technicians, sales and marketing specialists, and production managers. State and federal agencies employ Agronomists as extension specialists, county extension directors, environmental and natural resource specialists, research associates, soil surveyors, soil conservationists, and in regulatory agencies as plant, food, and grain inspectors. Additional areas of work open to Agronomists include integrated pest management, land appraisal, agricultural finance, turfgrass management, and the home lawn care industry.

The department offers an international scholar program leading to a credentialed title of "Agronomy International Scholar" for agronomy majors who have distinguished themselves in global understanding and international experience. Contact the department for requirements.
