  • Plant Breeders Without Borders
    Anthony Leddin
    Welcome to Plant Breeders Without Borders! Similar to the "Doctors Without Borders" concept, our organization aims to match volunteer plant breeders with projects overseas in underserved areas in the hopes of promoting the exchange of plant breeding knowledge. These volunteers would train locals to be plant breeders, as well as mentoring undergraduates involved in the project.  Ideally, the project leaves behind new, native plant breeders that are able to continue breeding work with support of the plant breeding volunteer from back in their home country.  If you are interested in involvement with this project, please contact Anthony Leddin at aleddin@valleyseeds.com.   Partners Melb Uni versity WA University  Sydney University Latrobe University FAO -CIAR Centre of underdeveloped crop species (Crops for the future) based in Malaysia. Australian Business Volunteers (ABV) Crawford fund The Noble foundation

  • UNL Soils Home Course
    Contact Keith Glewen with any questions. kglewen1@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 Keith Glewen at kglewen1@unl.edu.

  • North American Invasive Plant Ecology and Management Short Course
    Steve Young syoung4@unl.edu
    Welcome to the North American Invasive Plant Ecology and Management Short Course (NAIPSC) Online Community! The NAIPSC Online Community houses information about the NAIPSC Field Course, instructors, resources, and future opportunities to increase your knowledge of invasive plants. The 2013-2014 NAIPSC Webinar Series The 2013-2014 NAIPSC Webinar Series is now done. NAIPSC members can view the archived version by logging onto the NAIPSC Online Community. For more information about the NAIPSC Webinar Series and the Online Community, contact Steve Young. 2014 NAIPSC Web Course The first annual NAIPSC WC took place January 22-23, 2014. We had great sessions, good discussion, and no one complained about the food, hotel, or flight delays! If you weren't able to join us, don't worry because we recorded each session and have made them available in an 'archived' version. If you want to watch the sessions, contact Steve Young for details. Invasive Plants: Impacts on Ecosystems Are you interested in more than just how to control invasive plants? Have you had questions about where invasive plants occur and how they are impacting the most pristine to the most degraded ecosystems? Maybe you just want to know what an invasive plant is. If so, then you need to sign up for the all new course entitled, "Invasive Plants: Impacts on Ecosystems". In this 15-week course offered through the University of Nebraska-Lincoln, you'll learn how invasive plants in arid climates are affecting hydrological cycles, the changes below-ground caused by invasive plants, the legacies of invasive plants, and much more. The format of this 3-credit course is similar to other college-level courses, except that the all of the instruction, materials, and activities are located online. You can participate from anywhere to hear the pre-recorded lectures, and be involved in the discussion board and complete the problem sets and other various assignments. To put all of your new found knowledge to use, an optional final project on several topics including land manager interviews, invasive plant spotlights, and creating an educational program will be available. For any professional, researcher, student, or instructor working or teaching in the fields of conservation or land management, this course is for you. No other course is going to teach you the 'why' and 'how' relating to the establishment of invasive plants in terrestrial ecosystems. Find out more by contacting Dr. Steve Young (steve.young@unl.edu) or downloading a brochure. The 2014 course has already begun, but a shorter 5-week version is being developed.
