Principles of Soil Science

An integrated introductory course in soil science. An exploration of the interaction between soil and the environment, soil formation and morphology, soil physical, chemical, and biological properties and their influence on soil management, nutrient cycling, and soil-plant interactions.

Course code

Qualifications are made up of courses. Some universities call these papers. Each course is numbered using six digits.

189151

Level

The fourth number of the course code shows the level of the course. For example, in course 219206, the fourth number is a 2, so it is a 200-level course (usually studied in the second year of full-time study).

100-level

Credits

Each course is worth a number of credits. You combine courses (credits) to meet the total number of credits needed for your qualification.

Learning outcomes

What you will learn. Knowledge, skills and attitudes you’ll be able to show as a result of successfully finishing this course.

  • 1 Explain the physical properties of soils that affect energy, air, and water movement and the availability of water to plants and apply this knowledge to soil management.
  • 2 Describe the processes of soil formation, the association of specific soil types with different landscape units, the significance of soil morphological features, and the interpretation of soil maps.
  • 3 Explain the principles of soil chemistry with special attention to the development of surface charge, nutrient retention on soil surfaces, and plant mechanisms of nutrient uptake.
  • 4 Describe the dynamic nature of soil biology, including soil as habitat, factors that regulate soil organic decomposition and protection, nutrient cycling, and plant-microbe interactions and apply these concepts to soil management.
  • 5 Compare and contrast the attributes and limitations of common New Zealand soil orders and different cultural perspectives (including Māori) on soil management.
  • 6 Apply knowledge of soil science to investigate aspects of soil management in New Zealand and communicate the results in written format.

Learning outcomes can change before the start of the semester you are studying the course in.
