This unit applies to managers on farms that are managed according to the principles of organic agriculture. Work is likely to be done independently and according to the requirements of the National Standard for Organic and Biodynamic Produce.

ELEMENT

PERFORMANCE CRITERIA

1. Monitor indicators of soil fertility

1.1. Work is undertaken in an environmentally appropriate manner and according to workplace information, principles of organic agriculture, Occupational Health and Safety (OHS) requirements and enterprise guidelines.

1.2. Soil testing is conducted at reference sites according to enterprise procedures and organic industry standards.

1.3. Soil acidity or alkalinity (pH), mineral balances and organic matter levels are assessed and recorded.

1.4. Soil texture, structure, salinity and sodicity are assessed and recorded.

1.5. Soil biological activity is assessed and recorded

1.6. Soil condition is assessed for drainage, compaction, aeration and water infiltration in relation to requirements for desired plant growth for selected species.

1.7. Results are analysed to identify trends in soil health and fertility and areas for improvement.

2. Assess soil-related factors for selected plants

2.1. Nutritional requirements of selected plant species are identified.

2.2. Soil analyses to be conducted and suitable testing facilities are selected.

2.3. Plant tissue sample collection is conducted according to enterprise procedures and requirements of testing facility.

2.4. Results of tissue testing are combined with observations of plant vigour and productivity to determine management and input requirements of the farming system.

3. Select and implement allowable techniques and inputs to optimise soil fertility

3.1. Range of allowable inputs is identified according to requirements of the National Standard for Organic and Biodynamic Produce.

3.2. Cultural practices to enhance nutrient cycling are identified and implemented.

3.3. Appropriate inputs are calculated, based on soil/plant analyses, crop removal and plant/animal observations.

3.4. Cover crop and pasture systems are selected and managed.

3.5. Mulching and composting systems are developed, applied and monitored.

3.6. Rotations to optimise soil fertility are designed and implemented.

3.7. Cultural practices to enhance soil fertility are selected and implemented.

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:

understand and apply principles of organic agriculture

understand and apply knowledge of interrelationships between soil fertility, animals, plants, pests and diseases

devise and implement a soil improvement plan to correct imbalances and maintain soil fertility

analyse soil test results for a range of indicators of soil fertility

work with natural processes and allowable inputs to improve and maintain soil fertility.

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.

The range statement relates to the unit of competency as a whole.

Organic may include:

the application of practices that emphasise the use of renewable resources

conservation of energy, soil and water

recognition of livestock welfare needs

environmental maintenance and enhancement, while producing optimum quantities of produce without the use of artificial fertiliser or synthetic chemicals.
