NY312 - Nursery Irrigation, Drainage

The nursery industry in Australia, which is valued at $2.5 billion, depends extensively on irrigation at both the production and retail level. If not managed effectively irrigation water can cause runoff, which may contain undesirable levels of nutrients and pesticides. If uncontrolled, this runoff canhave adverse effects on the surrounding environment. To prevent these adverse effects from irrigating containerised nursery plants requires a thorough understanding of irrigation and drainage techniques, and acceptable methods of reuse or disposal of runoff water.
