METHODS OF INSTRUCTION (TYPICAL) Instructors of the course might conduct the course using the following method: Subject matter will be presented through class lectures, field labs, and shop labs Demonstration of operation of irrigation equipment Instructor-led discussion and elaboration on appropriate conclusions regarding water use Use of audio-visual materials Guest speakers Field trips D. ASSIGNMENTS (TYPICAL) EVIDENCE OF APPROPRIATE WORKLOAD FOR COURSE UNITS Time spent on coursework in addition to hours of instruction (lecture hours) C. D. Weekly lab report Given in class scenarios, students are required to develop an irrigation plan that meets the irrigation situation. Students will complete an irrigation project from design through installation. Weekly homework assignments that develop an understanding of the material taught during the lecture EVIDENCE OF CRITICAL THINKING Assignments require the appropriate level of critical thinking Sample assignments: Develop irrigation schedules for a given situation, keeping in mind uniformity, crop needs, system type and application rates. I need to apply 2 inches of water using a furrow irrigation system with a DU of 86%. How Division: Agriculture & Environmental Sciences 5 of 7

6 much water do I need to apply and how long should I run the 500 GPM pump in order to apply the 2 inches over 10 acres? Identify the following irrigation methods and provide two advantages and two disadvantages of each method. Discuss all the factors that make up a water budget for the state of Californi E.

DESIRED LEARNING OBJECTIVES Required Objectives Upon satisfactory completion of this course, the student will be able to: d. e. Identify irrigation system components and discuss their purposes and functions. Summarize the principles involved in the procurement, distribution, application, and management of water in agriculture. Explain why water conservation is important for agriculture and the environment. Demonstrate the ability to effectively setup an irrigation schedule in order to efficiently use water to meet specific crop needs. Identify various irrigation systems and be able to discuss advantages and disadvantages of each. f. Analyze a current irrigation system and make recommendations in order to improve irrigation efficiency. Lab Objectives Upon satisfactory completion of the lab portion of this course, the student will be able to: d. e. f. Analyze various irrigation systems and make changes to improve irrigation efficiency. Measure irrigation flow and determine the amount of water applied. Identify various irrigation systems and discuss how their uses differ with crop type and location in the state. Analyze soil moisture content and develop an irrigation schedule to bring soil moisture back to field capacity. Develop a preventative maintenance schedule for irrigation components which include pumps, filters, valves, sprinklers and emitters. Analyze CIMIS data and develop a crop specific irrigation schedule. Recommended Objectives Upon satisfactory completion of the course (when the related recommended content is covered) the student will be able to: Identify various irrigation equipment manufacturers and describe the products they provide.
