Manage a moving sprinkler irrigation system

Assessment tool

Version 1.0
Issue Date: April 2024


This Unit applies to irrigation managers in the food and fibre production industries.

This Unit covers the process of managing a moving sprinkler irrigation system and defines the standard required to: develop procedures for system operation; troubleshoot faults and blockages; measure performance of the system; and benchmark energy and water efficiency of the system.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Prerequisites

Employability Skills

This Unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

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:

read and follow operations manual and irrigation schedules

carry out pre-start checks

operate and inspect the system

measure and interpret flow rates and pressures

identify environmental hazards

shut down in response to irrigation indicators.

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.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills include:

Ability to:

measure output and efficiency of an irrigation system

develop and supervise procedures for starting up, carrying out operational checks and shutting down

monitor system effectiveness:

application rates

irrigation times

sprinkler coverage and output

soil moisture levels

pressure variations and blockages

salinity levels and water quality

depth of irrigation

infiltration and runoff

measure, interpret and adjust flow rates and pressures

fix blockages and replace components

use records to review an irrigation system.

Required knowledge includes:

Knowledge of:

moving sprinkler irrigation technologies

component specifications

pump types used in moving sprinkler irrigation systems and their output and efficiency ratings

servicing and maintenance of travelling mechanism

environmental hazards of runoff and compaction

general irrigation methods for moving sprinkler systems

main components of moving sprinkler irrigation systems

pump types used in moving sprinkler irrigation systems and their operation

energy efficiency indicators/ benchmarks for moving sprinkler irrigation:

Application Efficiency

Average Application Rate

Instantaneous Application Rate

soil moisture testing techniques

soil/plant/water relationships

water requirements of plants/crops consistent with sound environmental management

critical measures for moisture availability:

readily available water

wilting point

field capacity

monitoring soil compaction and drainage

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

irrigation schedules

environmental impacts of irrigation using water from any ground or underground source

best practices for reducing environmental impacts of irrigation

water requirements of plants/crops consistent with sound environmental management.

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Moving sprinkler irrigation systems may include:

moving sprinkler irrigation systems describe specifically hard and soft reel self-travelling irrigators, lateral move systems and centre pivots.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
