  • Irrigation Home Study Course
    Chuck Burr Extension Educator Univ of Nebraska chuck.burr@unl.edu
    The intent of this Home Study Course is to increase the user’s awareness and understanding of irrigation management concepts. This in turn can help producers reduce irrigation application amounts and increase uniformity of application, thereby reducing deep percolation and runoff. The end result can be reduced irrigation costs, increased efficiency, increased yields and reduced surface and groundwater contamination. The target audience for this course includes: crop consultants, agency personnel, irrigated crop producers and others interested in improving their irrigation water management skills. There is additional information on irrigation management on the UNL Water webpage: http://water.unl.edu/web/cropswater/home It is hoped that you find this course both helpful and enjoyable. To begin work in the course click on "Lessons" in the task bar above.  This will take you to a page where you can click on links to view each chapter.  We recommend that you print a few of the addenda, especially the Tables and the Equations.  For best printing results, set the printing properties to Portrait and, if available, to print both sides.  Upon completing a chapter you can take the quiz by clicking on the "Quiz" link included in each lesson; you may use your printed addenda while taking each quiz.  To earn CEU credit, you'll need to get 8 of 10 questions correct.  You may retake quizzes as many times as you wish.
