AHCIRG409A
Implement, monitor and adjust irrigation schedules

This unit covers the process of implementing watering shifts, monitoring factors that influence water requirements and adjusting the irrigation schedule to accommodate changes in those factors, and defines the standard required to: 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.

Application

This unit relates to implementing, monitoring and adjusting irrigation schedules will be carried out without supervision but with general guidance on progress.

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.
