water extraction and treatment procedures for turfgrass
use; interpret water quality test results to select suitable
water source for sports turf irrigation purposes; evaluate
principles of stream, pond, and lake management as a
means of water harvesting for irrigation of a sports turf
area; and determine construction features of bank walls as
a means of erosion control and bank stabilisation in a
selected turfgrass environment.
entry information:
Open.
accreditation option:
Evaluation of documentation and visit by NZQA and industry.
moderation option:
A centrally established and directed national moderation
system has been set up by the Primary Industry Training
Organisation.

storage, screening, aeration, coagulation, flocculation, clarification,
filtration, pH adjustment, disinfection, softening.
Analysis of the factors involved in using treated water identifies the implications
of its use on turfgrass areas.
Range:
factors may include but are not limited to – treatment procedures,
application mechanisms, transportation logistics, user reaction,
cost, adverse and beneficial soil and turf effects, human health.
element 2
Interpret water quality test results to select suitable water source for sports turf irrigation
purposes.
performance criteria
2.1
Interpretation of water quality test results identifies the physical, chemical, and
biological characteristics of water quality relevant to turfgrass growth.
Range:
physical, chemical and biological characteristics explained will
include but are not limited to – total soluble salts, electrical
conductivity, sodium hazard, pH, osmotic pressure, toxic ion
levels, bicarbonate, soil factors, colour, hardness, turbidity, odour,
biological oxygen demand, faecal coli concentration.
2.2
Interpretation of results determines if chemical, physical, and biological
characteristics of water quality conform to turfgrass growth requirements
identified in published scientific literature.
2.3
Interpretation of results identifies the level of tolerance warm season turf
grasses and cool season turf grasses will have to the tested water quality.

soil characteristics.
Range:
2.5
soil characteristics may include but are not limited to – sodium
and/or salinity hazard, structural stability, leaching ability, soil
texture, climatic zone.
