In the context of plant requirements and water quality, management has asked you to investigate the impact of scheduling irrigation according to daytime temperature.The nursery uses dam water and all the run off from the nursery eventually finds its way back to the dam via earthen channels.

The main plants grown here are woody ornaments. Your initial investigations show the daily water usage in similar sized plants varies by 300% and climatic conditions creates a further 300% variation in evaporation rates.

Outline a strategy you would use to improve the irrigation schedule including the steps would you take here. Include in your presentation an appreciation of the adverse environmental issues this activity may have and how would modify the nurseries policies and procedures to ensure changes were effectively implemented and monitored.
