Overview
With the world’s population now approaching 7 billion people, and expected to exceed 9 billion within 30 to 40 years, the demand for food is expected to double. Therefore, our ability to sustainably produce plants for food and aesthetic purposes is more crucial now than ever before. If you want to become a scientist with the skills and knowledge to grow crops or turfgrass to provide for human needs and improve environmental quality, then the Crop and Soil Sciences major at Virginia Tech is for you!
In the CSS program, students learn the fundamentals of plant science and improvement, and soil and environmental stewardship for feeding the world, protecting the environment, and producing quality turfgrass. As a student majoring in Crop and Soil Sciences, you can count on quality academic programs relevant for today and tomorrow, opportunities for involvement and experience, and individual and personal attention from our award-winning faculty and staff. Our programs offer the rigor, flexibility, and practical knowledge that will help you succeed regardless of the path you choose. You will learn the fundamentals of soil, plant, and environmental sciences to prepare you for your career.
Agronomy Option
Students in this option concentrate on the biology and increasingly complex technology of food, feed, fuel, and fiber production. Graduates typically move into farming or into sales, consulting, and managerial positions that directly and indirectly support agricultural production, a most vital component of the world's economy.
Crop Genetics and Breeding Option
Producing better quality and higher yielding crops has been a long-standing objective of crop breeders. New techniques of genetic engineering are now being brought to bear on crop improvement. Students in this option learn the newest methods of molecular biology and are well prepared for careers in research and industry.
International Agriculture Option
The world's ever-expanding population must be fed; at the same time, we must be good stewards of the Earth’s resources. Many countries have not been able to bring food production and resource conservation into balance. Students in the International Agriculture option are interested in finding simultaneous solutions to these concerns. Employment opportunities exist with various private and public agencies.
Turfgrass Management Option
Using basic principles of the natural sciences and agricultural technology, turf managers have skills that make them highly employable in golf-course management, athletic and recreational fields, lawn maintenance services, the landscaping industry, and sod production.
Requirements for a Major
All the curricula for the various options contain a core of courses to assist the student in developing knowledge and ability in basic sciences (biology and chemistry), computational skills (mathematics and statistics), communication skills (both writing and speaking), as well as crop, soil, and environmental sciences. A list of courses specified for each option may be obtained upon request from the department or at www.cses.vt.edu. In the following listing, semester hour credits are shown at the right.
