Sustainable Ag Systems

Semester Taught - Spring

Catalog Description

Credits: 3

Minimizing energy and costs in agricultural and natural resource systems and industries. Students explore ways to enhance sustainable systems by improving efficiency. Topics include agricultural machinery, pumps, motors, fans, refrigeration, lights and construction methods.

Pre-requisites/Co-requisites

Senior standing and 1st year physics.

Course Objectives

Students will be able to calculate efficient operational plans for agricultural and natural resources facilities.  Topics that students will analyze include:

  • Agricultural machinery
  • Lighting
  • Ventilation systems
  • Electric motors
  • Internal combustion engines (stationary and non-stationary)
  • Pumps
  • Refrigeration systems
  • Building systems and technology

Students will learn to analyze efficient operation and couple the results with economic analyses to reduce fixed costs.  Reduction of fixed costs will be shown to increase profitability and sustainability.

Time does not permit everything to be covered in the lectures and labs therefore, reading and homework will be assigned.  Exams will include outside reading material as well as that provided in the lectures.

Grading

A C- will not be a qualifying grade for critical tracking courses.  In order to graduate, students must have an overall GPA and an upper-division GPA of 2.0 or better (C or better).  Note: a C- average is equivalent to a GPA of 1.67, and therefore, it does not satisfy this graduation requirement.  For more information on grades and grading policies, please visit: https://catalog.ufl.edu/ugrad/current/regulations/info/grades.aspx

Exams 2 @ 50 each 100 points
Homework 10 @ 10 each 100 points

Academic Honesty

As a student at the University of Florida, you have committed yourself to uphold the Honor Code, which includes the following pledge: “We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honesty and integrity.” You are expected to exhibit behavior consistent with this commitment to the UF academic community, and on all work submitted for credit at the University of Florida, the following pledge is either required or implied: " On my honor, I have neither given nor received unauthorized aid in doing this assignment."

It is assumed that you will complete all work independently in each course unless the instructor provides explicit permission for you to collaborate on course tasks (e.g. assignments, papers, quizzes, exams). Furthermore, as part of your obligation to uphold the Honor Code, you should report any condition that facilitates academic misconduct to appropriate personnel. It is your individual responsibility to know and comply with all university policies and procedures regarding academic integrity and the Student Honor Code. Violations of the Honor Code at the University of Florida will not be tolerated. Violations will be reported to the Dean of Students Office for consideration of disciplinary action. For more information regarding the Student Honor Code, please see: http://www.dso.ufl.edu/SCCR/honorcodes/honorcode.php.

Accommodation for Students with Disabilities

The Disability  Resource Center coordinates the needed accommodations  of students with
disabilities.  This includes  registering  disabilities,  recommending  academic accommodations within  the classroom,  accessing  special adaptive computer equipment,  providing  interpretation services and mediating  faculty-student  disability  related issues. Students  requesting  classroom accommodation  must first register with the Dean of Students  Office. The Dean of Students  Office will provide  documentation  to the student who must then provide  this documentation  to the Instructor when requesting  accommodation

Software Use

All faculty, staff and student of the University are required and expected to obey the laws and legal agreements governing software use. Failure to do so can lead to monetary damages and/or criminal penalties for the individual violator. Because such violations are also against University policies and rules, disciplinary action will be taken as appropriate. We, the members of the University of Florida community, pledge to uphold ourselves and our peers to the highest standards of honesty and integrity.

Campus Helping Resources

Students experiencing crises or personal problems that interfere with their general well-being are encouraged to utilize the university’s counseling resources. The Counseling & Wellness Center provides confidential counseling services at no cost for currently enrolled students. Resources are available on campus for students having personal problems or lacking clear career or academic goals, which interfere with their academic performance.
