Overview
This broad discipline deals with crop production, utilization of soils, and stewardship of the environment. It is concerned with feeding the world, protecting the environment, and producing quality turfgrass. Graduates include professionals who monitor and work to improve water quality, who serve as agricultural loan officers for banks, who develop environmentally acceptable methods for protecting crops from pests, who advise municipalities on use of the land resource, and who maintain the greens and fairways at golf courses.
Graduates' familiarity with fundamentals of soil, plant, and environmental sciences prepares them for careers ranging from integrated pest management to international development, from environmental legislation to biotechnological investigation, from cash cropping to city planning. Students find employment in agribusiness (e.g. agricultural sales and consulting), soils-related activities (such as soil conservation and land-use planning), and other areas of environmental concern (e.g., biological control of pests and water quality assessment/control), as well as crop production (such as turf maintenance and farm management). Because of its breadth and diversity, the crop and soil environmental sciences major is divided, for advising and curricular purposes, into five undergraduate options.
Agroecology 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 U.S. economy.
Biotechnology and Genetics Option
Producing better quality and higher yielding crops has always been an 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 biotechnology 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.
Soil-Environmental Option
Human impacts on the environment and good stewardship of the soil and land resources are major focuses of this option. Graduates find positions with governmental agencies and private industry. They may deal with concerns such as soil conservation, groundwater pollution, land-use planning, waste management, and reclamation.
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.
