Definitions
Feedstock is a mixture of organic materials that form the food for worms in a
vermicomposting unit.
Vermicomposting refers to a mixture of vermicast and unprocessed organic matter; it may
also contain worm capsules and small worms. The term may also apply to a mix of
vermicast and composted material.
A vermicomposting unit is made up of a bed in which worms are placed, and worm cast
and (depending on the type of unit) liquid fertilizer is produced. The bed may include a
combination of – of aged manures or composted materials, shredded paper products,
decomposing leaves, straw, soil, vegetable or fruit discard materials.

Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated
authority for quality assurance, before they can report credits from assessment against
unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register
credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for organisations
wishing to develop education and training programmes, such as minimum qualifications for
