Soil testing

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, 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 will learn the newest methods of biotechnology and will be 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 world's resources. Many developing 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 be dealing with concerns such as soil conservation, groundwater pollution, land-use planning, waste management, or 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.

Course Requirements

  • 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, computer science, 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. In the following listing, semester hour credits are shown at the right.

    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 professional growth and recognition include department-sponsored agronomy and turf clubs, membership in Alpha Zeta and Gamma Sigma Delta (or other honoraries), and several scholarships designated for majors. 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 soil mineralogy, soil microbiology, soil chemistry and biochemistry, soil morphology and genesis, soil physics, soil and crop management, soil fertility, biotechnology, bioremediation, crop breeding, crop ecology, crop physiology, and seed physiology. (See the Graduate Catalog for more information.)
