Soil testing

Overview

    Crop and Soil Science integrates the basic sciences—biology, chemistry, physics, and mathematics—and applies them to challenges of sustainable plant production and soil and water management. As the world’s population grows toward a projected 9-10 billion people, crop and soil sciences will become increasingly important for ensuring the world’s food security.

    In the CSES major, students learn about plant production, genetics, and physiology; international aspects of crop production, and the science and management of turfgrasses. Students graduating with a degree in CSES will be competitive for jobs as crop consultants, crop breeders, specialists in international agriculture, soil scientists, and managers of golf courses and sports fields. The U.S. Bureau of Labor Statistics forecasts that employment of soil and plant scientists is expected to increase by 15% between 2008 and 2018, faster than the average for all occupations. Students majoring in CSES can choose from options in Agroecology, Biotechnology and Genetics, International Agriculture, Soils and Land Rehabilitation, and Turfgrass Management.

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 industries supporting production agriculture, crop and soil consulting, farming, or into sales and managerial positions that directly and indirectly support agricultural production.

Biotechnology and Genetics 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.

Soils and Land Rehabilitation 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 of disturbed areas.

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.

Requirements for a Minor

    The department offers minors in crop and soil environmental sciences, turfgrass management, and wetland science. The requirements for each include CSES/ENSC 3114 and 3124 (or 3134) and 15 or 16 more credit hours selected from courses from within and outside the department. Consult the department office (240 Smyth) or web site (www.cses.vt.edu) for more information on a minor.

Satisfactory Progress

    By the end of the academic year in which the student has attempted 60 hours (including transfer, advanced placement, advanced standing and credit by examination) "satisfactory progress" will include meeting the following minimum criteria:

  • having a grade point average of at least 2.0
  • passing at least 24 semester credits that apply to the Curriculum for Liberal Education

    6 hours of MATH and/or STAT
  • declaring an option within CSES

Opportunities to Excel

    Students with outstanding records can qualify for the Honors Program and graduate "in honors" in crop and soil environmental sciences. Other opportunities for personal and professional growth and for recognition include department-sponsored agronomy and turf clubs, membership in Alpha Zeta and Gamma Sigma Delta or other honoraries, and several scholarships. B.S. graduates are certifiable in the professional registry of the American Society of Agronomy.

    Graduate courses and research opportunities lead to M.S. and Ph.D. specializations in the crop, soil, and environmental sciences. (See the Graduate Catalog for more information.)
