Range of Variables The 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 areas may be considered part of the nursery environment? | Nursery environment may include glasshouses, shadehouses, and hardening-off areas. |
What environmental parameters are to be taken into account for this standard? | Environmental parameters may include light, temperature, humidity and wind. |
What market requirements may require the modification of environmental parameters? | Market requirements may include size of plant, extent of foliage, colour, time of sale, and number of blooms. |
How are daily water requirements determined? | Plant water needs are determined using water monitoring devices or physical observation applying mathematical formulas. |
What needs to be monitored to ensure plant water requirements are maintained? | Monitoring plant water needs may include soil moisture, condition and size of plant, and environmental parameters. |
What enterprise guidelines may be relevant to this standard? | Enterprise guidelines may include standard operating procedures (SOPs), specifications, production plans, work notes, Material Safety Data Sheets (MSDSs), or verbal direction from manager, or supervisor. |
What potting media specifications are relevant to this standard? | Potting media specifications may include pH, drainage, aeration, salinity nitrate levels, water repellence, and nutrient content. |
How is the overall healthof the plant monitored? | Monitoring the health of the plants may include checking the thickness of stems, evidence of pests and diseases, number, strength and distribution of new roots, maturity and distribution of shoots, visually complete and robust graft union, and no signs of dehydration. |
What plant interventions may be utilised to promote plant growth? | Interventions may include pesticides, fungicides, fertilisers, hormones, pruning, hardening off, irrigation, mulching, removing weeds, removing dead material, aeration, staking, tying, spacing and thinning. |
What OHS requirements apply to this standard? | OHS requirements may include handling hazardous substances, the use and maintenance of equipment and machinery, and the use of protective clothing. |
| |
What environmental considerations may be relevant to this standard? | Environmental considerations may include disposal of chemical containers and left over chemicals, and run off from washing and cleaning equipment and machinery. |
What workplace records are relevant to this standard? | Workplace records may include spray diaries, types of interventions applied, accident reports, and machinery log. |
