Course overview
This course covers topics in soil and water management and conservation important to students of agricultural, viticultural, and environmental sciences. Processes that degrade the soil- and water-resources of Australia (e.g. erosion, salinity, alkalinity and sodicity, as well as acidification, water repellence, and degradation of soil structure) are examined, and their measurement, avoidance and management discussed. There is a strong focus on quantitative theory and practice of measuring and managing soil water using commercially available technology, particularly in relation to interception, storage and movement of water in dryland and irrigated agro-ecosystems. Broader issues in soil and water conservation (e.g. State and Commonwealth legislation) are also covered. Practical classes consist of laboratory, computer and field exercises designed to illustrate the concepts covered in lectures.
Course learning outcomes
- Theory and measurement of soil water content, movement, storage and plant availability
- How to manage and measure salinity and sodicity in irrigated agricultural systems
- How to solve quantitative problems in soil water management, specifically how to:* conduct simple calculations of water content, porosity, density and hydraulic conductivity
- analyse and interpret data on infiltration, available water, and storage of water
- How to work effectively in small groups in the lab and in the field
- Successful students will be able to understand:The primary causes and consequences of a wide range of soil degradation problems, including soil acidity and alkalinity, erosion, salinity and sodicity, and nutrient loss
- The impact of soil management on soil organic matter, soil structural stability, water quality and other important soil properties
- Where soil conservation and management fit into the broader context of the South Australian Natural Resource Management Act
- and to:Develop an ability to collect and evaluate data in practical classes
- Develop writing skills through essay and report writing
- Learn how to provide and respond to “peer-review” feedback on a draft essay
