GEOG 318 –SOILS IN OUR ENVIRONMENT
Soil is central to life on earth. We rely on healthy soils for our very survival as soils are required for the growth of our food crops and for the production of fibre. The importance of soils to ecological functioning of the planet is becoming ever more apparent. Many human activities (such as industrial activity, agriculture and forestry) and natural occurrences (such as wind and rainstorms) have the potential to damage soils and vast areas of soils in many parts of the world have been degraded. This degradation includes soil erosion; desertification; chemical and microbiological pollution of soil and water; soil acidification; soil compaction; and soil organic matter depletion. It is essential that a large number of people obtain an understanding of soils and their functions in order to maintain the healthy functioning of our soils.
The objective of this course is to provide students with an understanding of soils and their properties and functions; and how proper management of soils is essential to their healthy functioning. Course topics will include: 1) the functions of soils in the environment; 2) the properties of soils, including physical, chemical and biological properties; 3) how soils can be degraded by natural occurrences and human activities (soil erosion, desertification, chemical and microbiological pollution of soil and water; soil acidification; soil compaction; and soil organic matter depletion); and 4) how soils can be managed to maintain or regain healthy functioning.
