Plant and Soil Sciences

The goal of the department is to meet societal needs for food, fiber, energy, and intrinsic value related to the conservation and management of plant and soil resources. Teaching, research, and extension efforts are designed to spur innovation and provide understanding regarding management of agricultural and environmental resources to increase long-term sustainability food production systems.

Undergraduate students select an option of study from: agronomic business, crop production and management, plant biotechnology and improvement, or soil and water resources. Students may choose to specialize in an area such as: entrepreneurship, forage and livestock production, pest management, plant genetics, precision agriculture or environmental management. In addition, students can fulfill prerequisites for professional programs such as pharmacy school. Students interested in professional certification will complete the necessary course requirements in their degree programs. Students have flexibility to work with their academic advisors to develop a plan of study to suit their interests. Many undergraduate students work with the research faculty on projects providing the student an opportunity to assist in gathering new information related to plant breeding and genetics, biotechnology, environmental remediation, plant physiology, crop production, weed science, soil nutrient management, soil chemistry, soil physics, water quality and land restoration.

Upon completion of a Bachelor of Science program, students are employed by private firms, public institutions, state and federal agencies, or non-profit organizations that require personnel with expertise in plant and soil systems. Typical careers include: federal employment in soil and rangeland conservation; crop consulting; technical sales and service for seed, fertilizer or agricultural chemical supply companies; farm or ranch operation; research positions as plant and soil scientists with federal agencies, state agricultural experiment stations or private industries; teaching and extension positions with colleges and universities; and a broad range of employment or ownership in retail businesses supplying feed, seed, grain, fertilizers, equipment, agricultural chemicals and other agricultural supplies and services. Our undergraduate program has also successfully prepared students to pursue advanced degrees in plant and soil sciences, agricultural economics, environmental science, and other related disciplines. Demand for individuals with experience in plant and soil sciences will continue as long as society demands a safe, secure food supply balanced with a desire to conserve natural resources.

Minor in Agronomy or Soil Science

The Department of Plant and Soil Sciences offers two minors, Agronomy (20 hours) and Soil Science (19 hours). Students pursuing a minor in Agronomy will take courses in areas that are most important for understanding the science of crop production, including genetics and biotechnology, weed science and nutrient management in order to prepare them for careers that support crop production. The Soil Science minor has a great deal of flexibility (12 credits of controlled electives) that will allow students to explore diverse aspects of soils ranging from chemistry to conservation while helping them prepare for a variety of environment-related careers.

Department/School: Plant & Soil Sciences

Programs of coursework and research are offered leading to a Master of Science degree in Plant and Soil sciences, a Doctor of Philosophy degree in Crop Science, or a Doctor of Philosophy degree in Soil Science. Specific program focuses are available in the areas of plant breeding and molecular biology, biotechnology, bioenergy, environmental remediation, forage, and pasture management, weed science, crop physiology, crop management, conservation cropping systems, soil morphology and genesis, soil microbiology, soil fertility and plant nutrition, soil physics, soil-water management, soil chemistry, soil and water quality, and waste management. Applicants should indicate their specific area of interest upon application. Plant and soil sciences faculty also serve on advisory committees for the Environmental Science interdisciplinary degree programs.

The graduate programs in plant and soil sciences prepare individuals for successful careers in a variety of areas including research, teaching, environmental sciences, waste management, farming and ranching, extension education, agricultural business, and all aspects of crop production.

Prerequisites

Admission to the graduate program requires a BS degree in plant and soil sciences, agronomy, or a closely related field. Applicants should have completed basic courses in plant and soil sciences, agronomy, biology, chemistry, and mathematics required of undergraduate majors. Deficiencies in fundamental course requirements will be met by the student under the direction of the student’s advisory committee. Applicants must be accepted by an adviser in an appropriate discipline prior to official admission.

Degree Requirements

Students must follow approved plans of study that meet the minimum University and program requirements for the respective degrees they are pursuing.

The plans of study for graduate programs are developed individually for each candidate and must adhere to guidelines in the Plant and Soil Sciences graduate student handbook and be approved by the student's advisory committee. The graduate degrees in plant and soil sciences requires a minimum of 30 credit hours beyond the BS degree for a Master of Science degree or 78 credit hours beyond the BS degree for a Doctor of Philosophy degree. These include six credit hours of PLNT/SOIL 5000 Master's Thesis or 15 credit hours of PLNT/SOIL 6000 Doctoral dissertation. All students must meet certain requirements in basic disciplines such as statistics, mathematics, botany, and chemistry. The study of a foreign language is not required but can be incorporated if the student and advisory committee feel that it is desirable.
