Case Contibutors:

Maja and Sandra are the appropriate contact persons regarding the general conduct of the course and some of the cases. Drs. Berch and Bomke and Mr. Van Ham prepared one case each and will be contributing their expertise during that specific unit of the course. In 2016/17, Drs. Prescott and Grayston , who have been contributing to this course over the years, are away on sabbatical and will not available to interact with students.

Course Description

Application of fundamental, unifying, soil science principles in sustainable management of forested, agricultural, and urban or constructed ecosystems.

Learning Outcomes

Upon completion of APBI 402/SOIL 502, students will be able to:

  1. Describe processes of soil genesis, recognize diagnostic features of natural soils, and relate management practices to information available in soil survey reports.
  2. Utilize physical, chemical, and biological soil quality indicators to assess sustainability of land management practices.
  3. Characterize the soil chemical environment and its modification to enhance plant, animal, and human health.
    • Specific topics may include: liming, fertilization, and remediation of chemical contamination
  4. Describe the soil biological processes with regard to nutrient cycling and management of organic inputs.
    • Specific topics may include: maintenance of soil organic matter, carbon sequestration, and recycling of various organic materials such as manures biosolids, and green manures.
  5. Describe the soil physical environment and its manipulation and/or degradation in ecosystem management.
    • Specific topics may include: compaction, trafficability, water management, soil erosion
  6. Discuss the relationship of soil management to government and private sector policies.
    • Specific topics may include Forest Practice Code, urban development regulation, right to farm and farmland preservation legislation, environmental farm planning, and land reclamation legislation

Course Format

APBI 402 is run in conjunction with SOIL 502, with students enrolled in both courses participating in a modified problem-based learning (PBL) environment to meet the course learning outcomes listed above.

The course learning outcomes will be met through three case studies, each four weeks in duration. Groups of 4-6 students will be assigned either a forestry, urban, or agricultural land management regime in which to pursue the case study learning outcomes. Each case will conclude with seminars from each group to enable a comparison of approaches within different land uses. Individual students will prepare 1,000 word reports summarizing their own personal learning for each case. Groups will be organized to facilitate interdisciplinary discussion and to provide opportunities for students from different programs to benefit from their varied experience and educational backgrounds. Class meetings each week shall consist of a 1-hour lecture and 2-hour discussion/PBL group activity.

There is no textbook for the course; background readings will be drawn from a variety of sources. Student assessment will be on the basis of a final examination, group presentations, individual student case reports, and a small component to recognize class participation.

(A) Written case reports of 1,000 words will be prepared by individual students and will be due a week after the group presentations. Written case reports will be assessed on the basis of content and quality of writing. Content of the individual case reports should demonstrate that the student has achieved the case learning outcomes and is able to discuss them in the context of the case scenario. Also, in 1-2 paragraphs, each student should compare/relate learning outcomes of his/her case to the cases presented by other groups. Some writing tips are given at the end of the course syllabus. All reports should be handed in on time and 10% mark subtraction will be made for each day being late.

(B) Group presentations will be judged based on content, structure, and delivery. More detailed criteria of group presentations are given at the end of the course syllabus.

(C) Term paper for SOIL 502 students of approximately 1,500 words on a soil management topic to be negotiated between the student and instructors.

(D) Class participation will be assessed on the basis of contribution to in-class (verbal) and online (written) discussions.

It is highly recommended that students attend SOIL 500 - Soil Science seminar (every Friday 3-4pm) since most seminar topics will be complementary to what we are covering in this course.

Judging Criteria for Group Presentations

Group presentations will be judged based on content (6 points), structure (3 points), and delivery (1 point).


1. Content was presented in a clear and concise manner.

  • Explains theory and potentially complex material clearly (e.g., no jargon or jargon is explained).
  • There was sufficient detail for an out-of-field observer to follow the presentation.

2. Objective for your case study was clearly articulated.
3. Provide explanation on how were data collected (e.g., study sites and management treatments are described, differences among soil types are explained).
4. Explain the key findings of your study case (e.g., summary of main points, suggestions for future research/directions, thought-provoking comments on where do we go from here).
5. At the end of your presentation, post 2 questions about the most relevant findings of your case.


  1. The presentation started in a manner that captured the audience’s interest and was relevant to the body of the presentation.
  2. The points were presented in a logical manner.
  3. The presentation is closed in a manner that links key findings to the study case’s objective.
  4. Length (kept to allotted time).


  1. The students’ presentation kept the audience’s interest and engaged the interest and participation of the other groups.
  2. Audio-visual aides were used in a manner that supported the presentation.
  3. Speech: projected well (everyone could hear), presenters did not speak too quickly.
  4. Handled questions well (if did not understand question paraphrased back to the questioner, demonstrated critical thinking if answer is not immediately obvious, makes an educated guess, if does not know the answer says so, shows confidence in ability to answer questions).

Case Report Writing Tips

Case reports will be evaluated based on content and organization (6 points), comparison of your own case to other cases (3 points), and grammar and clarity of the writing style (1 points). Pls submit your term papers as Word (not pdf) files. Word limit of 1,000 words does not include tables, figures, list of references, cover page, and appendix (assuming that you decide to include an appendix in your paper).

Content and Organization

•Tips on how to approach preparing this report:

  • Before you start writing the report, make an outline and identify the key sub-sections.
  • During the writing process, refer frequently to the learning outcomes to keep yourself on track.
  • Before you submit the paper, make sure that it is correct, clear, concise, consistent, and complete (co-called 5 Cs of communication).

•Provide background information on the study site(s) and management practices (or treatments if your case is done on an experimental field) as well as soil type, climate, topography, parent material, and type of vegetation on the study site(s). Soil type should be discussed regarding its natural advantages and disadvantages for a specific management practice.

•Outline study objective(s).

•Develop a soil quality framework [Function -- Process -- Attribute (Property) -- Indicator] and justify selection of indicators focusing on the management practices of your case study.

•Discuss the data of your case study.

•Briefly summarize the body of your report and restate your argument. Check it against the study objective(s) to make sure you have not wandered away from it.

Comparison to Other Cases

In 1-2 paragraphs, compare and/or relate key findings of your case to the cases presented by other groups. Focus on the soil function, processes and properties (indicators) and do not go in any elaboration of different management practices used in different case studies. Consider developing a table highlighting similarities and differences between cases.

Grammar and Writing Style

•Keep your sentences simple. That does not necessarily mean that your thoughts are simple. Complex and adjective-laden sentences just make your great ideas hard to follow.

•Each paragraph should contain one main idea. Paragraphs should be logically organized. For example, you should discuss ideas in the order in which they appear in your introduction.

•As a university student, you are expected to submit original work and give credit to other peoples' ideas; hence, plagiarism will not be tolerated. If you are unclear on the concept, please see
