Elements and Performance Criteria

ELEMENT	PERFORMANCE CRITERIA
1. Monitor plant or crop environment for irrigation requirement	1.1. Plant or crop environment is monitored and results are interpreted according to enterprise policy and procedures. 1.2. Plants or crops are inspected for signs of stress. 1.3. Changes to irrigation shifts are recommended according to environmental conditions and plant or crop requirements.
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 co-ordinated 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 Occupational Health and Safety (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: use enterprise monitoring equipment monitor plant or crop environment for irrigation requirement check water supply and availability implement irrigation shifts evaluate effectiveness of irrigation activities
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.
