Objectives:

To familiarise students with the basic geology and geomorphology of south-eastern Australia; to introduce the combinations of soils, plants and animals that comprise the main agricultural systems of this area, with particular reference to Victorian agriculture, and to demonstrate how the application of science provides the basis for improvements in productivity and the development of environmentally-acceptable practices. On completion of this subject, students will be able to apply the principles developed in relation to agricultural land use in Victoria to other regions and agricultural systems. They will also appreciate the importance of relationships between the various scientific disciplines of agricultural science, and the emphasis placed on integration as well as discipline strength in solving complex problems associated with biological systems functioning at large scales.

Content:

Introduction to the landscape of south-eastern-Australia and the geological processes that resulted in the formation of that landscape. The relationship between crystalline structure, chemical composition and the physical properties of common minerals; rocks as aggregates of minerals; an introduction to igneous, sedimentary and metamorphic rocks and weathering processes. The distribution and formation of the major soil types in Victoria. Broad land use categories in Victoria and south-eastern Australia. The influence of climate, geology and soil type on land use capability. Climate and weather in Victoria and their effects on plant and animal productivity; examples of the distribution, management and economic performance of important crop, pasture and animal industries in Victoria. Consequences of improper land use; examples of land degradation - decline in soil physical conditions, loss of soil fertility, development of soil salinity and soil acidity. Off-site effects of agricultural activity - erosion and water quality; concepts of integrated catchment management; waste management.
