Elements and Performance Criteria

Elements

Performance Criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Interpret the irrigation schedule

1.1 Confirm activity to be undertaken, including identifying potential hazards and risks and implementing safe working practices to manage risks

1.2 Select required tools and equipment and check for safe operation

1.3 Select, fit and use personal protective equipment applicable to the task

1.4 Access information on plant growing requirements

1.5 Interpret growing season moisture requirements

1.6 Read the predicted seasonal moisture deficit and watering requirements and check with management

1.7 Record parameters for the irrigation system

2. Determine irrigation shifts

2.1 Subdivide irrigated area into units capable of individual irrigation and note area and irrigation equipment characteristics for each

2.2 Define soil irrigation capability for each unit

2.3 Define crop and plant water requirement for each unit

2.4 Combine units requiring similar irrigation into irrigation shifts

2.5 Ensure irrigation shifts do not exceed water delivery capacity of the property irrigation infrastructure

2.6 Determine the water volume required to meet irrigation needs over specified period

3. Implement irrigation schedule

3.1 Coordinate resources and brief personnel to deliver requirements

3.2 Implement watering program

4. Monitor irrigation

4.1 Inspect plants and crops for growth rate and signs of stress

4.2 Record frequency of irrigation

4.3 Measure and record water usage and confirm water allocation is not exceeded for a given period

4.4 Calculate the difference between estimated and actual water use

4.5 Measure water quality

4.6 Assess plant and crop growth and water use efficiency

4.7 Measure soil for readily available water (RAW)

4.8 Record climate and weather conditions

4.9 Adjust watering program in response to rainfall events and changes to evapotranspiration rates

5. Record irrigation information and activities

5.1 Record plant or crop environment data according to workplace recording procedures

5.2 Record water usage

5.3 Record irrigation shifts

5.4 Record system process data
