Description
This unit of competency describes the skills and knowledge required to assess physical and moisture properties of soil, monitor soil chemical properties, assess soil health and plant growth under irrigation, and implement strategies to optimise irrigation on the soil plant growing environment.The unit applies to individuals who monitor soils under irrigation under broad direction and take responsibility for their own work.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Assess the physical properties of irrigated soil
  • 1.1 Identify the profile of irrigated soil
  • 1.2 Determine soil texture and structure within the soil layers
  • 1.3 Interpret tests for organic matter level in soil
  • 1.4 Test for slaking and dispersion in irrigated soil
  • 1.5 Assess the infiltration rate for irrigated soil
  • 1.6 Measure soil moisture levels
  • 1.7 Assess the environmental impacts of cultivation and watering practices on the physical properties of soil
2. Monitor soil moisture properties
  • 2.1 Identify soil moisture tension and its role in determining water availability to plants
  • 2.2 Assess the field capacity of irrigated soil
  • 2.3 Observe the wilting point for a plant species in irrigated soil
  • 2.4 Calculate the readily available water (RAW) in irrigated soil
3. Monitor soil chemical properties
  • 3.1 Interpret soil test results for salinity and sodicity levels in irrigated soil
  • 3.2 Interpret pH tests and the potential impact of pH on soil structure and nutrient availability
4. Implement strategies to optimise the irrigation growing environment for plants
  • 4.1 Assess the risk of erosion in irrigated soil
  • 4.2 Implement and monitor a watering schedule
  • 4.3 Adjust the frequency of watering based on available moisture, soil properties and plant response
  • 4.4 Record and report soil and plant moisture status and irrigation requirements
