This unit applies to the management of a horticultural production site consisting of one or several controlled growing environments. The work is usually undertaken without supervision, with only general guidance on progress sought by senior management. Responsibility for the work of others may be involved and team coordination may be required. Management of controlled growing environments requires extensive horticultural knowledge and practical skills, particularly in plant physiology and growth needs, controlled environment systems, monitoring, reporting and forward planning.

ELEMENT

PERFORMANCE CRITERIA

1. Identify crop requirements

1.1. Crop growth and production requirements are determined according to a documented production plan.

1.2. Environmental parameters for optimal growing conditions for the specific crop are researched using available information resources.

1.3. Controlled growing environment factors are identified, evaluated and recorded.

2. Determine requirements for controlled growing environment

2.1. Structures, machinery, equipment and resources required to control environmental conditions are identified, costed and availability confirmed.

2.2. Occupational Health and Safety (OHS) hazards are identified, risks assessed and controls implemented.

2.3. Detrimental environmental impacts associated with the controlled growing environment system are identified and controls sanctioned.

3. Prepare a management plan for controlled growing environment

3.1. Management objectives for controlled growing environment are determined consistent with production plan and market requirements for crop quantity and quality.

3.2. A schedule of environmental control procedures is developed according to controlled environment management objectives.

3.3. Staff training needs are evaluated in regard to operation and maintenance of environmental control systems, and reported.

3.4. A budget supporting the controlled environment management plan is documented and approval sought.

3.5. The schedule of environmental control procedures is communicated clearly to staff.

4. Manage controlled growing environment

4.1. Controlled environment indicators and thresholds for remedial action are identified for monitoring according to industry best practice.

4.2. Monitoring frequency and schedule is developed according to the requirements of the production plan and communicated clearly to staff.

4.3. All monitoring data is recorded, analysed and applied to management of the controlled environment system to ensure optimal plant development.

4.4. Remedial action undertaken is documented and reported.

4.5. Costs of the controlled growing environment system are monitored against budget.

4.6. Budget adjustments are recorded and reported.

4.7. Recorded information, budget data and production outputs are evaluated and operational achievements towards management objectives are documented in a report.

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:

identify the growing requirements of the crop

prepare specifications for controlled growing infrastructure

develop a management plan to cover staff training, budgets, operating procedures and remedial actions

develop environmental monitoring procedures

evaluate and document the achievements towards management objectives.

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.

The range statement relates to the unit of competency as a whole.
