Elements and performance criteria
Element 1
Describe the nutrient requirements of turf.
Performance criteria
1.1
Turf growth is described in terms of the role of and requirements for major and
minor nutrients.
1.2
Turf systems are described in terms of the mechanisms of nutrient loss.
Range
1.3
Turf systems are described in terms of the mechanisms of nutrient availability.
Range
1.4
mechanisms of nutrient availability – pH, cation exchange capacity
(CEC), soil moisture, micro-organism activity, soil temperature.
Turf is described in terms of the effect of environmental and management
factors on annual nutrient requirements.
Range
1.5
mechanisms of nutrient loss – volatilisation, denitrification,
clippings removal, leaching, plant uptake.
clippings removal, wear and traffic, playing quality, growth pattern,
drainage, growing media, length of playing season, climate.
Turf growth and development are described in terms of the effects of major
nutrients.
Range
at least five of – root/shoot ratio, colour, disease susceptibility,
plant hardiness, recovery from wear, botanical composition,
establishment and density.
Element 2
Describe the properties and characteristics of turf fertilisers.
Range
at least five of – soluble, slow release, organic, inorganic, salt index, particle
size, acidity, granule, liquid, foliar, solid, straight, mixture, compound.
Performance criteria
2.1
Turf fertilisers are described in terms of their solubility and formulation.
2.2
Turf fertilisers are described in terms of the percentages of major nutrients they
contain.

2.3
Turf fertilisers are compared in terms of their advantages and disadvantages.
Range
comparisons may include but are not limited to – rate of release,
size of granule, ease of application, storage and handling,
characteristics, effects on soil and plant, price, and availability.
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
tutors and assessors, and special resource requirements.
