Elements and Performance Criteria

ELEMENT	PERFORMANCE CRITERIA
1. Monitor plant health	1.1. Workplace information is interpreted and clarified with the supervisor. 1.2. Growth rate of plants are assessed against targets set in the production plan. 1.3. Plants are assessed for overall health according to sound horticultural practice. 1.4. Plant is assessed for onset of fruit according to production plan.
2. Monitor the hydroponic environment	2.1. Environmental parameters are monitored according to the production plan and adjustments made as required. 2.2. Samples are collected and sent off for analysis to identify potential sources of contamination. 2.3. Hygiene procedures are monitored and adjusted according to enterprise guidelines. 2.4. Disposal of materials is monitored to ensure it follows enterprise guidelines, and with due consideration of the environmental implications.
3. Monitor nutrient solution	3.1. Ingredients of the hydroponic nutrient solution are identified. 3.2. Samples are taken for testing and analysis. 3.3. Results are interpreted and discussed with the supervisor. 3.4. Nutrient solution is modified in accordance with results to ensure the correct balance of ingredients for optimum growing conditions.
4. Perform routine maintenance checks	4.1. All buildings and structures are inspected and checked for wear and tear. 4.2. Equipment for delivering the nutrient solution is checked according to enterprise guidelines. 4.3. Equipment controlling the atmospheric and root zone environments is checked according to enterprise guidelines. 4.4. OHS hazards are identified, risk assessed and suitable controls implemented according to enterprise guidelines.
5. Complete monitoring activities	5.1. Any significant problems are reported to the manager and/or owner operator. 5.2. All checks are recorded according to enterprise requirements.
