    Contact Keith Glewen with any questions.
    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

    Undergraduate Students in TCAP Click on the map below to see where TCAP students are located across the country.  Once the map opens in a new tab you can click on the red dots to learn more.   Undergraduate Research Internships in Plant Genetics and Plant Breeding The Plant Breeder Training Network for Undergraduate Students (PBTN – US) provides an excellent experience for students who wish to understand the science of plant genetics and plant breeding and acquire training in research. Students will gain knowledge and skills by assisting a graduate student with research and, with advice from their graduate mentor, planning and implementing an independent research project.   Purpose To meet global demand for food in the coming decades, new crop varieties adapted to conditions of changing climate, limited land, water and nutrient resources and unyielding disease pressure are needed.  This work requires the collaborative efforts of scientists with knowledge in the areas of genetics, genomics, breeding strategies and experimental design and the application of tools of molecular genetics and computational biology.   PBTN-US provides a way for undergraduate students to gain experience and skills in many of these areas, to learn about careers in research, and to prepare for the next step in their own research career. PBTN – US provides: paid research internships mentoring by trained graduate students interaction with undergraduate interns at other institutions interaction with professional plant breeders in academia and industry funds for travel to a scientific conference to present research results   To learn more about research internships, click below for a description of research projects and contact information. Research Projects   Please contact us with any questions you have about plant breeding or internship opportunities.   Mary Brakke   Jamie Sherman   Deana Namuth-Covert

  • Crop Science Investigation (CSI) Network
    Brandy VanDeWalle
    Crop Science Investigation (CSI) Network         This site is designed to serve as a clearinghouse of lesson plans and other materials useful for teaching 4-H and FFA youth about crop and soil sciences.  Check out this site for information to use in your classroom, workshops, or 4-H meetings.        As youth become less connected with agriculture, it is essential to teach them about agriculture. A series of workshops, called Crop Science Investigation or CSI was created to help spark the interest of youth to learn about crops and plants. Dig into some interesting facts about Nebraska crops. Learn how crops grow and factors that affect them. Learn about exciting career opportunities related to crop and plant science. The University of Nebraska offers great majors for anyone interested in anything plants!  Check it out!

    Making a Gene Library
    This animation shows how to make a colony of new DNA in order to locate a specific gene of interest. This is the third of four animations detailing the gene cloning process. To begin at the beginning, choose Making a Recombinant Plasmid. (The animation prior to this one is Bacteria Transformation. The animation just after this one is Screening a DNA Library.)
