Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA 

1. Determine irrigation shifts

1.1. The irrigated area is subdivided into the smallest units capable of individual irrigation and area, and irrigation equipment characteristics are noted for each.

1.2. Each unit is defined for its soil irrigation capability.

1.3. The crop/plant water requirement is defined for each unit.

1.4. Units requiring similar irrigation are combined to form a shift that does not exceed the water delivery capacity of the property irrigation infrastructure.

2. Check water supply and availability

2.1. Water volume required to meet irrigation needs over specified period is determined.

2.2. Water is ordered, if necessary, according to water management authority standards and procedures.

2.3. Sufficient notice of water order is given, if necessary, to ensure water is available when required.

3. Implement irrigation shifts

3.1. Resources are coordinated and personnel briefed to deliver requirements.

3.2. Agreed irrigation schedule is implemented.

4. Evaluate effectiveness of irrigation activities

4.1. Plant or crop environment is monitored according to enterprise policy and procedures.

4.2. Plants and crops are inspected for signs of stress.

5. Monitor irrigation system process as specified by enterprise policy and procedures

5.1. Frequency of irrigation is recorded.

5.2. Water usage is measured and recorded, and does not exceed water allocation for a given period.

5.3. Differences between estimated water use and actual water used are calculated.

5.4. Water quality is measured according to enterprise OHS policy and procedures.

5.5. Plant or crop growth and water use efficiency is assessed.

5.6. Soil chemical characteristics are measured and soil moisture is assessed.

5.7. Labour performance is measured.

5.8. Climate and weather conditions are recorded.

6. Record irrigation information and activities as specified by enterprise policy

6.1. Plant or crop environment data is recorded

6.2. Water orders and water usage is recorded.

6.3. Irrigation shifts are recorded.

6.4. System process data are recorded.

Evidence Guide

EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

  • estimate water availability for plants/crops
  • determine irrigation shifts and rates
  • monitor and record irrigation data
  • analyse moisture monitoring equipment data
  • evaluate effectiveness of irrigation.

Context of and specific resources for assessment 

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.
