Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Plan for extremes of weather

  1. Modify estimated deficits to cater for any prolonged saturation following heavy rainfall
  2. Alter shift areas, and where applicable, application rates, to suit appropriate irrigation schedules that minimise frost damage
  3. Implement strategies involving prioritising of plants and crops and intermittent irrigation at times of extreme heat

The candidate must provide evidence that they can:

apply a measured amount of water

assess the efficacy of irrigation and repeat cycles of irrigation

incorporate data from in-field equipment and remote monitoring sources into scheduling systems that compute irrigation requirement

monitor crop and plant water use

plan for extremes of weather

record irrigation and scheduling parameters

use and maintain in-field equipment that monitors the plant environment

The candidate must demonstrate knowledge of:

in-field irrigation reticulation performance and its capacity limits

inter-relationship between plant, soil and the aerial environments in the determination of water budgets

physical soil characteristics such as infiltration rate, water holding capacity and wetted volume in the root zone

possible adverse impacts on the crop and environment from inefficient scheduling or unpredictable weather effects

recognition of moisture stress effects (sometimes desired) on plants

relevant environmental policies and procedures

water authority standards and procedures

water quality monitoring methods and acceptable quality limits
