Deep drainage and runoff, combined with poor nitrogen fertiliser practice, is resulting in significant nitrogen losses in early season irrigation.

A survey was conducted to ascertain the presence of feral cotton plants in off-farm drainage areas and along roadsides associated with cotton production and transport throughout Queensland and parts of northern NSW.

This case study looks at the project: Soil Management for Australian Irrigated Agriculture.

Australia's water resources are in a serious state, both in reduced quantity and declining quality due to

techniques. In response, this project was commissioned to investigate the potential of reducing nutrients in irrigation drainage systems using in-line wetland technology and batter stabilisation.
