Crop and Soil Science
The discipline of crop science provides the knowledge and understanding of technologies that contribute directly to improvements in production and quality of food, feed, fiber, seed, energy, and nutraceutical crops for the world. The art and science of plant improvement are key elements in efforts to feed, clothe and provide energy for the world’s ever-growing population. Conventional and molecular tools assist in the development of new genetic strains of food and energy crops. Crop plants play an important role in the future of sustainable food and energy production.
The discipline of soil science provides the basic understanding of the physical, chemical, and biological properties of this important natural resource. Why is soil important? Soil is the fundamental substrate for life on terrestrial landscapes. Soil plays a vital role in sustaining human welfare and assuring future agricultural productivity and environmental stability. An understanding of global and local ecology depends on an awareness of the soil and its properties. Global information and mapping systems are essential tools for characterizing the landscape and its constituent soils.
Agronomists are crop and soil scientists who work to improve crops and agricultural productivity while effectively managing pests and weeds. Students in crop and soil science explore important contemporary issues faced by our society, including water quality and management, sustainability of different types of crop production, organic crop production, erosion and sedimentation, growing crops for biofuel production, land use and reclamation, genetic modification of crop plants, and soil quality and sustainability. An array of careers is available.
Career Opportunities
Careers for crop scientists are available in business, industry, farming, research, agricultural chemical industries, seed production, seed technology, communications, conservation, and education. Positions are available in agricultural experiment stations and extension services, state departments of agriculture, food processing companies, insurance agencies, lending institutions, and commercial firms, both domestic and international, dealing in the processing and sale of farm products, chemicals, and seed.
Careers for soil scientists are available in agriculture, forestry, education, state and federal resource agencies, private consulting, and research. Farms, ranches, and agricultural supply companies employ soil scientists as managers or field representatives. Soil scientists may become teachers of vocational agriculture or environmental education, or they may become county extension agents in agriculture or natural resources. The U.S. Department of Agriculture's Forest Service and Natural Resources Conservation Service often employ soil scientists, as do private consulting firms in environmental engineering and land use planning.
Academic Advising
Undergraduate curricula in crop and soil science are flexible enough to provide for the student's individual professional needs and interests and for a broad-based general education by allowing electives in other colleges throughout the university. Undergraduate advising is a vital part of the program, and the department is well known for excellence in advising. The department has a head advisor who meets with all students each term. Advisors and faculty provide curricular guidance and aid in professional extracurricular activities, career decisions, and job placement.
Scholarships
The Department of Crop and Soil Science administers a number of scholarships available only to students majoring in the department. Over $40,000 is given to students each year.
Student Clubs
The department supports a Crop Science Club that provides valuable co-curricular professional development, a collegiate Soil Judging Team that participates in both regional and national competitions, the OSU Organic Growers Club that provides hands-on experience in organic production of vegetable crops, and the OSU Bug Club, a student club whose members are actively engaged in insect education outreach to local schools and communities. Graduate students in soil science also have a student club.

Many sustainability crises are local, and the people most impacted tend to be groups already experiencing difference, lack of power, and discrimination. Transformational responses led by those most affected will be examined -- responses that address the environmental problem while also building social and economic power for those affected. The tools and tactics used to achieve positive changes will be analyzed. (Bacc Core Course)
