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. Take soil samples from a number of places in the permaculture system | 1.1 Obtain samples from several places over a site 1.2 Prepare the samples for testing 1.3 Label containers accurately with location identifier, date, soil test and tester |
2. Test soil for range of plant and structural needs | 2.1 Carry out soil tests for texture, organic matter, structure, pH, water infiltration and compaction 2.2 Have samples tested by a laboratory for nutrient levels and deficiencies if concerned or if particular requirements exist for the crops and livestock in the permaculture system 2.3 Re-test in a different season or soil temperature |
3. Analyse soil improvement requirements | 3.1 Determine requirements for soil improvement from tests carried out 3.2 Determine requirements for soil improvement from the laboratory test results, if taken 3.3 Identify soil biota in soil and ascertain how to optimise biodiversity 3.4 Research soil improvement options, including discussing with neighbours and experienced practitioners appropriate options for soil improvement |
4. Implementing soil improvement plan | 4.1 Develop a plan for soil improvement over time and vary it depending on the location on the site and the crop or livestock being grown 4.2 Calculate required quantities of allowable additives and supplements to improve soil health 4.3 Use products at recommended rates and according to any existing certification system applying to the land 4.4 Protect soil biota present in soil, including using appropriate mulches for perennial and annual plants |
5. Maintain health of soil according to organic guidelines | 5.1 Observe changes over time and record using tables and photographic records 5.2 Avoid practices that can cause deterioration in soil health such as over- or under- watering, over-grazing, over-cultivating and off-contour ploughing 5.3 Follow organic and permaculture guidelines to increase soil carbon |
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:
take soil samples
test soils
analyse soil improvement requirements
implement soil improvement plan according to permaculture guidelines
maintain soil health
The candidate must demonstrate knowledge of:
permaculture principles and practices related to soil health and plant nutrition
working with natural soils rather than importing soil
soil as an ecosystem
soil as biomass and carbon capture and storage
principles of sustainable horticultural practices
how to read a laboratory soil test
soil testing techniques, such as:
jar test for soil structure
ribbon test and ball test for soil texture
infiltration or permeability test
pH testing
compaction test
non-wetting soil test
air-filled porosity test
worm count
microscopic biota in soils
plant nutrient uptake and mineral action
soil chemistry
science of composting
fungal and bacterial action and mulches appropriate to different plants
additives to improve soils, such as
compost and worm castings compost teas
biochar
green manures
organic mulch
manures/animal bedding materials
leaf mould
plantings – green manures, nurse plants
companion planting
chop and drop
nutrient trapping systems
greywater use
organically certified products
amendments that may include rock dust, gypsum, dolomite, lime, zircon, sulphur and other minerals
plant growth and development
soil life, including microscopic life
methods of waste disposal causing minimal impact on the environment
the effects of conventional agricultural chemicals on soils and soil ecosystems
Assessors must satisfy current standards for RTOs. Assessors must also hold a nationally accredited Certificate III (or higher) in Permaculture. Completion of a Permaculture Design Course (PDC) is not sufficient at this level.
