What an assessment for AHCIRG339 must cover

39 assessable components: 4 elements (17 performance criteria), 6 performance evidence and 12 knowledge evidence requirements, plus 4 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Assess the physical properties of irrigated soil

  • 1.1Identify the profile of irrigated soil
  • 1.2Determine soil texture and structure within the soil layers
  • 1.3Interpret tests for organic matter level in soil
  • 1.4Test for slaking and dispersion in irrigated soil
  • 1.5Assess the infiltration rate for irrigated soil
  • 1.6Measure soil moisture levels
  • 1.7Assess the environmental impacts of cultivation and watering practices on the physical properties of soil

2 Monitor soil moisture properties

  • 2.1Identify soil moisture tension and its role in determining water availability to plants
  • 2.2Assess the field capacity of irrigated soil
  • 2.3Observe the wilting point for a plant species in irrigated soil
  • 2.4Calculate the readily available water (RAW) in irrigated soil

3 Monitor soil chemical properties

  • 3.1Interpret soil test results for salinity and sodicity levels in irrigated soil
  • 3.2Interpret 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

  • 4.1Assess the risk of erosion in irrigated soil
  • 4.2Implement and monitor a watering schedule
  • 4.3Adjust the frequency of watering based on available moisture, soil properties and plant response
  • 4.4Record and report soil and plant moisture status and irrigation requirements

Performance evidence

  • conducted soil structure and texture assessment
  • used soil moisture monitoring equipment
  • calculated moisture holding capacity of plants, including readily available water (RAW)
  • applied the results of soil testing to assessing soil properties
  • assessed the erosion potential of the irrigated soil
  • adjusted watering practices to meet plant needs

Knowledge evidence

  • soil structure and texture
  • effect of dispersible soils under irrigation
  • critical measures for moisture availability
  • adverse environmental impacts of irrigated plant production
  • field capacity
  • signs of moisture stress & nutrient deficiency in plants
  • wilting point
  • soil moisture definitions and calculations
  • RAW calculations
  • interpreting salinity, sodicity and pH tests
  • soil moisture monitoring procedures
  • types of erosion

Foundation skills

  • Reading: Interpret textual information from a range of sources to identify relevant and key information about workplace operations
  • Writing: Use correct terminology to document soil and plant moisture status and irrigation requirements
  • Oral communication: Use clear language to describe irrigated soil profile, impacts of cultivation and watering practices, and soil moisture tension, and to report soil and plant moisture status and irrigation requirements
  • Navigate the world of work: Recognise and follow workplace requirements, including safety requirements, associated with own role and area of responsibility

Questions about assessing AHCIRG339

What does an assessment tool for AHCIRG339 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AHCIRG339 needs to address all 39 unit components: 4 elements with 17 performance criteria, 6 performance evidence requirements, 12 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for AHCIRG339?

Auditori pulls the current release of AHCIRG339 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for AHCIRG339 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AHCIRG339 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of AHCIRG339, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
