Description of course: The course is an introduction to scientific principles and management of soil fertility. Students in this course will study material provided in course with 11 topics for 13 weeks in the Spring 2019 Semester. Some units are lengthy and will take two weeks of instruction. A total of 13 quizzes will be taken in the units as students progress through the course. Topics that last for two weeks will have two quizzes. The quizzes are based on readings that are in the online textbook. Students can take the quizzes at their own paces and in any order. All quizzes should be completed by the end the of the Spring 2019 Semester when reporting of grades is due (May 14, 2019). The Students also will participate in a Discussion Forum that will include topics of general issues in soil fertility and on topics that are not necessarily in the textbook. Students are expected to participate in the discussions for an average of twice per week by making entries into the Discussion Forum. Discussion topics will be available in the course structure online. Students do not need to participate in all topics but must participate 26 times.

The content and workload of the course is identical to the resident course in soil fertility at the University of Massachusetts.

Topics (from the textbook):

  1. Introduction and factors of soil fertility

2&3. Crop growth and factors affecting it

3&4. Acid soil infertility

  1. Liming
  2. Modeling of crop growth
  3. Soil testing and plant analysis
  4. Management of fertilization
  5. Tillage
  6. Nitrogen, phosphorus, and potassium fertility in soils
  7. Cropping systems and soil fertility
  8. Green manures and soil fertility
  9. Livestock and soil fertility

Grading: Quizzes 90% & Discussion 10%

Textbooks: A textbook for the course is available online. The textbook includes all of the topics of the course and is written so that it is the text of lectures that would be given in a classroom presentation. The quizzes for the course will be prepared from the textbook that is online.

Recommended: This book is much more extensive in coverage of soil fertility than the online version that accompanies the course and may be useful to support the understanding of topics of soil fertility. The 8th edition international version is inexpensive.
