Course Overview

The objective of this course is to give you a fundamental knowledge of soil science. If you are a student interested in agricultural, forest, rangeland, wetland, or constructed ecosystems, a basic understanding of soils is essential for you. The soil provides an ideal system in which to observe practical applications for basic principals of biology, chemistry, and physics. In turn, these principles can be used to minimize the degradation of soil as one of our fundamental natural resources.

Learning objectives for this course are:

  1. identify and characterize elementary aspects of soil formation,
  2. discuss basic soil physical, chemical, biological, and morphological properties,
  3. explain behaviour of soils in managed and natural landscapes, and
  4. identify 10 soil orders in the Canadian Soil Classification System.

Pls note that APBI 200 is offered in 2 sections - section 001 taught by Dr. Maja Krzic, and section 002 taught by Dr. Sandra Brown.

Note for auditors - For Auditor status to be entered on the transcript you will have to attend at least 75% of the lectures and to submit problem sets and laboratory assignments.

Note about plagiarism - 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 http://learningcommons.ubc.ca/resource-guides/avoiding-plagiarism/

Academic Honesty – Academic honesty is a core value of scholarship. Cheating and plagiarism (including both presenting the work of others as your own and self-plagiarism) are serious academic offenses that are taken very seriously at UBC. By registering for courses at UBC, students have initiated a contract with the University that they will abide by the rules of the institution. It is the student’s responsibility to inform themselves of the University regulations. Definitions of Academic Misconduct can be found on the following website http://www.calendar.ubc.ca/vancouver/index.cfm?tree=3,54,111,959

If you are unsure of whether you are properly citing references, please ask your instructors for clarification before the assignment is submitted. Information about academic integrity
