The Crop and Soil Sciences major is based upon the continuously expanding knowledge base of the biological and physical sciences and the utilization of those sciences to produce food and fiber of high quality on a competitive basis to promote sustainability, and to obtain increased nutrient–use efficiency, proper land use, increased plant adaptation to environmental and other stresses, decreased soil erosion, and decreased environmental pollution. Crop and soil scientists utilize the principles of genetics, plant breeding, crop physiology, weed science, turfgrass science, soil physics, soil fertility, soil genesis and classification, and soil chemistry.

Majors complete a common core of courses and one concentration: Agronomic Sciences, Turfgrass Management or Advanced Study.

1. Agronomic Sciences is designed to prepare students to work as agronomists. These scientists have career opportunities in agricultural business and in government agencies such as departments of agriculture and/or natural resources, the Natural Resources Conservation Service and the Extension Service. They also work and consult pest management specialists and managers of grower organizations and with land appraisal firms, agencies involved with environmental issues, and in international agriculture.
2. Turfgrass Management is designed to prepare students for the rapidly expanding area of urban agriculture. Graduates have career opportunities in the industries involved with management of golf courses, athletic fields, lawns and park and grounds management.
3. Advanced Study is specifically designed for those students who plan to pursue graduate studies. Although students who complete the other concentrations may pursue graduate study, this concentration requires the completion of advanced levels of mathematics and advanced courses in the basic science.

Students may qualify to teach agriscience in high school under a plan of study cooperatively developed by the student’s faculty advisor and the Department of Community, Agriculture, Recreation and Resource Studies.
