  • Building Hydroponic Systems
    Brian Waters bwaters2@unl.edu
    Welcome!  "Buildling Hydroponic Systems"  in an educational project being developed by the Waters Lab at the University of Nebraska-Lincoln. Dr. Brian Waters has developed a system that can be used by researchers and educators to experiment with the uses of hydroponic systems. Please join this community for updates as new learning materials become available.    This site has been developed through grant funding provided by the National Science Foundation (NSF). 

  • 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.

  • UNL Soils Home Course
    Contact Brian Krienke with any questions. krienke.brian@unl.edu
    Welcome to the UNL Soils Home Course!   The purpose of this course is to increase the users' knowledge of soil science including the origins, physical properties and chemical properties of soil.  This will aid users in making management decisions related to soil fertility and crop production.  This in turn can improve the efficiency of fertilizer applications, reduce nutrient loss, an improve crop yields. This course is intended for crop consultants, agency personnel, crop producers, and others interested in soil science and soil fertility management. We hope you find this course to be enjoyable and informative.  To begin working 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.  Upon completing a chapter you can take the quiz by clicking on the "Quiz" link included in each lesson.  To obtain CEU credits for the Certified Crop Advisor program, you will need to earn 75% on the quiz(zes).  You may take quizzes as many times as you wish. For any questions, please contact Brian Krienke at krienke.brian@unl.edu.
