Description
This unit of competency describes the skills and knowledge required to monitor water use, apply a measured amount of water, assess efficacy of irrigation and repeat cycles, record irrigation and scheduling parameters, and plan for extremes of weather to determine irrigation scheduling requirements.The unit applies to individuals who apply specialised skills and knowledge to irrigation scheduling. This includes applying and communicating non-routine technical solutions to predictable and unpredictable problems.No licensing, legislative or certification requirements are known to apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Monitor crop and plant water use
  • 1.1 Estimate or measure water use from one or more systems
  • 1.2 Accumulate water as a soil water deficit in the root zone
2. Apply a measured amount of water
  • 2.1 Predict a pre-determined deficit using a scheduling system
  • 2.2 Apply irrigation to partly or fully replace the deficit
  • 2.3 Increase water quantities where appropriate to ensure dilution and transport of toxic solutes below the root zone
3. Assess efficacy of irrigation and repeat cycles of irrigation
  • 3.1 Measure effectiveness of irrigation application with in-field equipment
  • 3.2 Adjust estimated soil moisture level in scheduling system to match in-field measurements
  • 3.3 Recalibrate scheduling system where necessary
  • 3.4 Repeat cycles of irrigation until schedule is correctly established
4. Record irrigation and scheduling parameters
  • 4.1 Record each irrigation and significant rainfall event, plus other appropriate parameters used in scheduling system
  • 4.2 Estimate and record drainage amount below root zone at each irrigation
  • 4.3 Record system performance data
5. Plan for extremes of weather
  • 5.1 Modify estimated deficits to cater for prolonged saturation following heavy rainfall
  • 5.2 Alter shift areas, and where applicable, application rates, to suit appropriate irrigation schedules to minimise frost damage where applicable
  • 5.3 Implement strategies involving prioritising of plants and crops and intermittent irrigation at times of extreme heat
