AHCPHT406
Control Phase II mushroom substrate process

Assessment tool

Version 1.0
Issue Date: April 2024


This unit of competency describes the skills and knowledge required to control Phase II of mushroom substrate.

It applies to individuals who analyse information and exercise judgement to complete a range of advanced skilled activities and demonstrate deep knowledge in a specific technical area. They have accountability for the work of others and analyse, design and communicate solutions to a range of complex problems. All work is carried out to comply with workplace procedures.

No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.

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


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.

Element

Performance criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Confirm the requirements for Phase II mushroom substrate preparation

1.1 Monitor and manage Phase II mushroom substrate process and ensure that all equipment is operated safely

1.2 Check to ensure all temperature probes are functioning correctly

1.3 Ensure site quarantine protocols and farm and personal hygiene requirements are followed

1.4 Assess condition and quality of compost before filling

2. Carry out Phase II process

2.1 Monitor placement of probes in air and substrate

2.2 Check the evenness of filling and the amount filled

2.3 Ensure doors are secure and vents and thermostats are set at completion of filling

2.4 Measure and record key factors and critical points

2.5 Adjust equipment settings to ensure optimum conditions for each Phase II sub-stage

2.6 Take random representative samples for laboratory testing

2.7 Determine ammonia levels before cool down for spawning

The candidate must be assessed on their ability to integrate and apply the performance requirements of this unit in a workplace setting. Performance must be demonstrated consistently over time and in a suitable range of contexts.

The candidate must provide evidence that they can:

assess room or tunnel layout and determine most appropriate locations for taking substrate and air measurements

carry out effective troubleshooting during Phase II process

differentiate between Phase I substrate and substrate ready for spawning and describe desired parameters of each stage

monitor and manage Phase II process for at least eight crops

The candidate must demonstrate knowledge of:

principles and practices for controlling Phase II processes

concept of compost selectivity and biological indicators of compost quality

correct probe placement and calibration

factors influencing air quantity and distribution

farm standards and procedures, including those relating to workplace health and safety, food safety, Hazard Analysis Critical Control Point (HACCP), quality systems, emergency procedures, organisational structure

interpretation of chemical test results

how different systems (shelf, tray and tunnel) impact on temperature zones in substrate

key parameters to be recorded and monitored relating to temperature, ammonia and moisture content

objectives and desired parameters of each sub-stage of Phase II substrate preparation

overview of Phase I compost production and how it impacts on Phase II process

relevant legislation and industry codes of practice

site quarantine protocols

Assessors must satisfy current standards for RTOs.

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.

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.
