COST-EFFECTIVE TEMPORARY MICROIRRIGATION SYSTEM FOR GRASS ESTABLISHMENT ON ENVIRONMENTALLY SENSITIVE STEEP SLOPES

An advanced technology cost-effective drip irrigation and set-up on environmentally sensitive elevated steeps of a coal train derailment site in Central Queesland, Australia, are presented. The irrigation system is described in detail. It was used to aid the establishment of grasses on the batters of the well-compacted soil to control erosion. The irrigation system worked very well and excellent grass coverage was established. However, the spreading and incorporation methodology needs to be improved.
