Elements and Performance Criteria

1. Monitor and maintain the nursery environment
   • Environmental parameters are monitored against the needs of the plants and enterprise guidelines.
   • Environmental parameters are altered, as required, to meet the needs of nursery plants and market requirements.
   • Irrigation system components are serviced for basic operational use and basic user serviceable parts are repaired or replaced.
2. Determine daily water requirements
   • Water requirements are determined according to the needs of the plant and environmental parameters.
   • Water is applied according to the needs of the plant group.
   • Water requirements of the plant are monitored according to enterprise guidelines.
3. Promote plant growth by intervention
   • Potting media is tested in production areas to ensure quality specifications are met.
   • Health of the plant is monitored according to enterprise guidelines.
   • Plant interventions are undertaken according to marketing plans, appropriate stage of plant growth for the particular intervention, and Occupational Health and Safety (OHS) requirements.
   • Waste is disposed of with full consideration of the environmental implications.
   • Records are kept on all maintenance activities according to enterprise requirements.

Evidence Required

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 calculate daily water needs recognise stages of plant growth monitor plant health integrate range of plant maintenance activities monitor the effects of plant interventions prepare mix and use chemicals as required
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
