    Gen100 - Issues in Agriculture ; Credits - 3
    An introductory course requiring critical analysis of issues in agriculture development and an historical survey of agriculture development. Written and oral communication is emphasized. .
    Instructors: David W. Williams Scott Smith
    PLS103 - Plants, Soils and People: A Global Perspective; Credits - 3
    Only a few things are essential to life, and food is one of them. What people eat is about what they need to be healthy, what they want to eat (personal preference and culture), and what they have available or can afford to eat. Agriculture plays a vital role in human food security. Many experts feel the world is facing a food supply crisis. Knowledge and application of the principles of plant and soil sciences will have a dramatic effect on human food security, now and into the future, both locally and globally. However, these issues will also be impacted by future human population growth, urbanization, consumer preferences, human decisions regarding civic duties, and climate change. Students successfully completing this course will leave with an understanding of the need to sustainably e.

    May be repeated for a maximum of nine credits. Prereq: Consent of appropriate instructor before registration. .
    Instructors: David W. Williams
    A field-based learning experience in plant and soil science under the supervision of a faculty member. May be repeated for a maximum of six credits. Pass/fail only. Prereq: Complete learning contract before registration..
    Instructors: David W. Williams
    Pls490 - TOPICS IN PLANT AND SOIL SCIENCE. ; Credits - 3
    A capstone course for majors in Plant and Soil Science to be taken near the conclusion of the student's academic career. The course provides the student the opportunity to integrate knowledge acquired in previous courses in the plant and soil science and support areas. Emphasis will be placed on problem solving, synthesizing and integrating information, critical thinking, group activities, and written and oral communication. Instructional methods may include formal lectures, laboratories or supervised individual research. The specific nature of the course depends upon the student's Area of Emphasis within the Plant and Soil Science major. All topics offered will be approved by the Undergraduate Education Committee in the Area of Emphasis. Prereq: Senior in Plant and Soil Science. .
    Instructors: David W. Williams
    Pls515 - TURF MANAGEMENT; Credits - 3
    A study of the selection, culture, and management of certain turf species used for home lawns, golf courses, athletic fields, and highway slopes. Lecture, two hours; laboratory, two hours. Prereq: PLS 210 and PLS 366..
    Instructors: David W. Williams
