Range of VariablesThe Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in particular training and assessment requirements may depend on the work situations available |
What soil and plant tests may be conducted as part of a sports turf maintenance program? | These may include on-site and off-site testing of the soil to determine physical characteristics such as colour, texture, structure, depth of rootzone and depth of watertable, and chemical characteristics such as pH, salinity, nutrient and carbonate content, and testing the nutrient status of plants through plant tissue testing. |
Who may be referred to as a client? | Clients may include the enterprises management or a private individual, company, community group, management committee, sporting association, government agency, or a combination of these entities. |
What range of conditions may affect plant nutrition? | Conditions may include weather, seasonal influences, soil characteristics, nature and frequency of use, fertiliser history, irrigation methods and scheduling, spraying program and soil management practices. |
What sports turf maintenance procedures may apply to this standard? | Maintenance procedures may include soil and turf plant tissue testing, applying nutrients, watering, rolling, mowing, monitoring turf plant health, renovating where necessary, and preparing the sports turf playing surface to presentation standards. |
What resources may be required for maintaining sports turf playing surfaces? | Physical resources may include soil and plant testing consumables, materials to modify soil pH, soil ameliorants to improve soil fertility, fertilisers to meet the nutritional requirements of turf species and cultivars, and weed, pest and disease control materials.Human resources may include paid labour, contractors, suppliers and consultants. |
What tools, equipment and machinery may be required for the implementation of the sports turf maintenance program? | Tools, equipment and machinery may include soil and plant tissue testing equipment; turf maintenance hand tools; 3-point linkage, trailed or motorised turf maintenance machinery; and irrigation and drainage systems and components. |
What OHS hazards may be identified as part of the sports turf maintenance program? | Hazards may include disturbance or interruption of services, solar radiation, dust, noise, air-, soil- and water-borne micro-organisms, chemicals and hazardous substances, sharp hand tools and equipment, manual handling, moving vehicles, machinery and machinery parts, slippery and uneven surfaces, and flying objects. |
What controls may be introduced to minimise the risk of OHS hazards? | Controls should be introduced according to enterprise OHS policies and procedures and may include identifying hazards; assessing and reporting risks; cleaning, maintaining and storing tools, equipment and machinery; appropriate use of personal protective equipment including sun protection; safe operation of tools, equipment and machinery; safe handling, use and storage of chemicals and hazardous substances; correct manual handling; appropriate use of safety equipment such as signage and protective barriers; basic first aid available on site; personal hygiene, and reporting problems to supervisors. |
What environmental implications may be associated with the implementation of a sports turf maintenance program? | Over-spraying or run-off into the external environment may result in nutrient overload or excess water to native plants, natural waterways, watertables and ecosystems, water erosion, water logging and salinisation.Beneficial impacts may include the minimisation of nutrient run-off and toxic side effects in soil and surrounding environment from improved assessment and targeting of nutrient requirements, application techniques and rates, and the reduction of toxic side effects of applied nutrients in the turf plants.Responsible fertilisation and watering practices may help to reverse previous environmental degradation by allowing natural recovery and regeneration of native ecosystems. |
What specifications may be included in the sports turf maintenance program? | Specifications may include types and frequency of soil and turf plant tissue testing, a turf plant nutrition program, irrigation scheduling, mowing frequency, height of cut, pattern, mowing directions and specified equipment, rolling instructions, observable turf quality parameters for monitoring turf health, and preparation procedures for achieving presentation standards. |
What remedial action may be undertaken to improve plant nutrition? | Remedial action may include adjustments to irrigation scheduling and nutrient application rates and methods, and changes to soil management practices. |
