Abstract

The Carnarvon horticultural area has suffered considerable erosion damage following flooding of the Gascoyne River.

The purpose of this report is to describe the factors that contribute to soil erosion in the Carnarvon horticultural area (Section 1), provide guidelines for good soil management (Sections 2) and provide floodway hazard classes and associated soil management recommendations (Section 3).

This report:

  • Provides detailed information on soil management for intensive irrigated cropping.
  • Details cropping alternatives to better manage the soil erosion risk.
  • Identifies appropriate plants for soil stabilisation in a range of situations.
  • Promotes the concept of property management plans.
  • Takes account of current management techniques within the limitations imposed by the water resource, climate and financial considerations.
  • Provides current hazard mapping of local floodways.

Periodic revision will be required as experience, technology and legislative change occur. Grower innovations and practice should be monitored, assessed and incorporated into these guidelines as appropriate.
